Propecia (finasteride) is a 5 alpha-reductase inhibitor. It works by inhibiting the conversion of testosterone into 5 alpha-dihydrotestosterone (DHT), a hormone that plays an important role in hair loss. Propecia is a prescription medicine and is only approved for use in men. There are other 5 alpha-reductase inhibitors on the market but Propecia is the only one approved for androgenetic alopecia.


Turns out low stomach acid results in malabsorption of iron (which as you know is necessary for maintaining our hair) and many other essential nutrients. Thanks to this article I discovered my own issues with low stomach acid and found help with Pure Encapsulations Betaine HCL with Pepsin. This has also helped me with heartburn, gas, acid reflux, and bloating. I know what you are thinking, all of you with heartburn and acid reflux are taking antacids to do the opposite – reduce, neutralize acid. Hmmm. Maybe the real source of your discomfort is too little acid and the real solution is increasing acid instead!

Medical conditions and medications. A common medical condition that also causes hair loss is hypothyroidism, which can happen in both men and women. Patients suffer from an underactive thyroid gland, which is responsible for producing the hormone, thyroxin, which performs important bodily functions, such as the regulation of body temperature, proper utilization of carbohydrates and fats, and production of protein. Since protein is an important nutrient for the production of keratin, inadequate protein supply in the body due to an underactive thyroid means that hair growth in the follicles is slow. In men especially, hair loss is one of the first signs of hypothyroidism.

Collagen is the most abundant protein in your body found in your skin, hair, bones, and tendons. Our body produces less and less of it as we age. I’ve long read about the benefits, including improved skin and nails and even pain reduction, of replenishing our depleting collagen stores with a form easily assimilated by the human body including hydrolyzed collagen and gelatin. I became particularly interested in collagen for hair loss when I read about a study published in Science in 2016. It all started with investigating the hair follicle stem cells of mice where researchers discovered that age-related DNA damage triggers the destruction of a protein called Collagen 17A1. The hair follicles of older people then convert themselves into skin cells, and over time baldness ensues. Think of the image of each hair follicle on your head disappearing leaving behind bare skin one at a time and on and on. My favorite brand is Vital Proteins Collagen Peptides grass-fed and pasture-raised.
The earlier you begin treating hair loss, the more effective the treatment will be. Androgenetic alopecia is a condition that gradually worsens over time, so the general rule is that the earlier you seek treatment, the better. “If you’re losing your hair and you have genetic hair loss, using medication such as Propecia or minoxidil is most effective when started early,” says Dr. Robert M. Bernstein, Dr. Wolfeld’s colleague at Bernstein Medical – Center for Hair Restoration. Because not everyone loses hair on the same timeline, you can’t rely on statistics to tell you when you should start treatment. Some men start to notice thinning in their early 20s, while others maintain a thick head of hair well into their 50s. If you suspect that you’re starting to lose your hair and want it to stop, act quickly.
Multiple vitamins, including biotin, have been promoted for hair growth, but solid scientific studies for many of these claims are lacking. While taking biotin and other supplements marketed for hair, skin, and nails probably won't worsen anything, it may also not necessarily help the situation. Therefore, advertised hair-regrowth supplements should be approached with mild caution. There is only anecdotal evidence that oral or topical application garlic, onion juice, saw palmetto, coconut oil, evening primrose oil, apple cider vinegar, creatine, and pumpkin seed oil are of benefit for hair loss.
Hair multiplication. Similar to the idea of cloning, this treatment involves taking out donor cells from the hair follicles and then growing and multiplying them in a laboratory. Once sufficient samples have been multiplied, these hair cells are then injected into the bald patches to stimulate hair growth. As a relatively new treatment, hair cloning is still in its research phase.
Just as pregnancy hormone changes can cause hair loss, so can switching or going off birth-control pills. This can also cause telogen effluvium, and it may be more likely if you have a family history of hair loss. The change in the hormonal balance that occurs at menopause may also have the same result. “The androgen (male hormone) receptors on the scalp becoming activated,” explains Mark Hammonds, MD, a dermatologist with Scott & White Clinic in Round Rock, Texas. “The hair follicles will miniaturize and then you start to lose more hair.”
Localized or diffuse hair loss may also occur in cicatricial alopecia (lupus erythematosus, lichen plano pilaris, folliculitis decalvans, central centrifugal cicatricial alopecia, postmenopausal frontal fibrosing alopecia, etc.). Tumours and skin outgrowths also induce localized baldness (sebaceous nevus, basal cell carcinoma, squamous cell carcinoma).
Laser treatments. Low-level laser therapy (LLLT) is used for the prevention and reversal of hair loss. Also known as red light therapy, cold laser, and soft laser, it is a form of light/heat treatment (therefore generally safer) that is used on cases of pattern baldness and alopecia areata. The procedure uses a device that emits light that penetrates into the scalp. The more commonly used lasers are the excimer, helium-neon and fractional erbium-glass. The procedure can increase the blood flow in the scalp to stimulate the follicles that are in resting or dormant phase to go into anagen, and at the same time, prevent the production of DHT, which destroys the hair follicles.

Treatments for alopecia areata include injecting small amounts of steroids like triamcinolone into affected patches to stimulate hair growth. Although localized injections may not be practical for large areas, often this is a very effective treatment in helping the hairs return sooner. Other treatments, such as oral steroids, other immunosuppressives, or ultraviolet light therapy, are available for more widespread or severe cases but may be impractical for most patients because of potential side effects or risks. In most mild cases, patients can easily cover up or comb over the affected areas. In more severe and chronic cases, some patients wear hairpieces; nowadays, some men shave their whole scalp now that this look has become fashionable. Recently, investigators have noted some beneficial results in small groups of patients with extensive alopecia areata or alopecia totalis with a JAK1/2 inhibitor, baricitinib (Olumiant). Long-term studies are under way.

When hair loss is related to a medication, stopping the drug usually prevents further hair loss, and the hair will eventually grow back. Hair also tends to grow back after most illnesses, radiation therapy, or chemotherapy. Wearing a wig or hat can hide the hair loss until the hair returns. Hair transplants are a more permanent hair-replacement solution.

A good hair care regimen and diet can prevent hair loss and promote longer hair in combination with vitamins. In many cases, hair loss is caused by vitamin deficiency called telogen effluvium, which temporarily pushes hairs from the growth phase of the hair growth cycle to the resting phase, causing hair loss. Telogen effluvium is temporary and the treatment is to eat more of the key vitamins that contribute to healthy hair growth. You can prevent hair loss due to vitamin deficiency or other nutritional deficits, such as key minerals and proteins, by having a good hair care regimen and eating a well-balanced diet of hair loss foods.
Patel said the problem with those treatments is that they have not been subjected to large or head-to-head research. There's great variation in how doctors give the plasma treatments and in laser-based devices, so it's hard for patients to know whether they're getting a proven regimen. Nutrafol seems promising, he said, but he does not think that company-funded research showing its effectiveness has been replicated. He has not recommended it yet.
Again, you’ll want to visit your doctor to get a blood test to check your levels in these vitamins. For example, women who have iron levels lower than 70 nanograms per milliliter are considered deficient. From there, work with your doctor to find an appropriate dose according to your deficiency level. Excessive or unnecessary supplementation can be dangerous.
While the drug is generally safe for use, some possible side effects are mild irritation of the scalp, dryness and growth of hair on some parts of the body, especially the sides of the face and hands. In some cases, you might observe some increased hair loss around the first few days of use. If the hair fall continues after two weeks upon application of minoxidil, stop the treatment first and see a doctor.
My name is Marsha… I have hypothyroidism… Type 2 diabetic. I’m currently taking Levothyroxine and Metformin… I am so depressed. My hair is brittle everytime I brush or comb it comes out in clumps. It’s very thin it literally feels like a Brillo pad no matter how much I moisturize it comes falling out I can just brush my hand across it and the hair just falls out like snow. I just went to the doctor last week and he says everything is normal and He suggests that I see a dermatologist is the dermatologist the person I should see? Or should I see an endocrinologist. I’m at my wit’s end I’m tired of searching for the right wig to wear nothing is more appealing than my own hair and a long to get it back. But I need to find the right doctor that can perform the right test. My doctor doesn’t seem to be helping me I don’t even know where to start. I don’t go out anymore… I’m just home hibernating period. A woman’s hair has a lot to do with the self esteem in mind is very low at this time. My whole wardrobe consist of every color scarf and hat you can imagine… Where should I start what doctor should I see first?
Most men experience hair loss as they get older, but for some it starts as early as their 20s or 30s. We offer both Finasteride and Propecia as prescription-only hair loss treatments. If you order Finasteride or Propecia from our discreet online service, you can pick it up from one of our pharmacies the same day, or have it delivered the following day.

Wash your hair at least once every three days with a gentle hair cleanser or shampoo to remove all the accumulated dust, dirt, oil, and bacteria build up. Keep it clean at all times to avoid hair fall from clogged follicles. It is also important not to wash your hair more than thrice a week. Overwashing will strip your scalp and hair of the natural oils that are essential for healthy hair growth.
"This is an oral, prescription-only medication with the brand name Propecia that’s also FDA approved to treat hair loss," says Spencer. Male pattern hair loss occurs when a hormone called dihydrotestosterone (DHT) prevents hair follicles from getting the nutrients they need. Finasteride works by blocking the production of DHT, which protects the follicles.
When hair loss is related to a medication, stopping the drug usually prevents further hair loss, and the hair will eventually grow back. Hair also tends to grow back after most illnesses, radiation therapy, or chemotherapy. Wearing a wig or hat can hide the hair loss until the hair returns.

Telogen effluvium - occurs mainly due to the body’s reaction to stress, brought about by, illnesses such as cancer, mental and emotional disturbances, medications such as blood thinners, hormonal imbalances, stress during childbirth and so on. In this condition hair thinning occurs on the scalp. The hair usually regrows after the stress period is over.

While thinning generally worsens after menopause, doctors said hormone treatments typically do not improve hair growth. Minoxidil lotion or foam, which can be purchased over the counter, is the first line of treatment. About half of women who use it have not lost more hair a year later, Cotsarelis said. Spironolactone, a blood-pressure drug, can also help, doctors said. Some may also try finasteride — approved to treat baldness in men — off-label. The evidence that it works in women is weak, Patel said.

2. Volumizing shampoos and treatments. Typically, these work by depositing ingredients, like wheat protein and keratin, that adhere to the hair shaft to a) thicken it and b) create spaces between hairs so you look like you have more of it. Try Kiehl’s Rice & Wheat Volumizing Shampoo ($18) with hydrolyzed wheat protein; Rogers likes Redken Cerafill Defy Shampoo and Conditioner ($20 each) with ceramides that bulk up hair.
These are the best hair supplement pills I've tried (and I've tried a lot). My hair gets greasier faster so I can tell it's helping to nourish and produce healthy oils at the root. I have definitely noticed faster hair growth when I'm using this product vs when I'm not. I actually only do 1 pill per day instead of the 3 (to save money) and it still works well.
It will be a mistake if lack of volume does not appear on the list of common hair problems. Happening for both men and women, lack of volume can be the factor that destroys one’s hair and affects his or her look. There are plenty of reasons leading to the lack of volume of flat hair, including thyroid problems, hormone-related conditions, low iron levels, and nutrition. It is believed that the wrong shampoo or inappropriate conditioner can make your hair too heavy and result in lack of volume. Sometimes, product build-up can be the hidden causes for most of the common hair problems, including lack of volume.
Men may also experience some sexual and emotional side effects while taking it: In a study published in the June 2011 issue of The Journal of Sexual Medicine, Dr. Michael Irwig of George Washington University found as many as 92 percent of test subjects reporting problems in the bedroom. The study also reported that “the mean duration of finasteride use was 28 months and the mean duration of persistent sexual side effects was 40 months,” meaning that side effects lingered long after subjects stopped taking the pill.
This makes finding reliable information a challenge, and to further complicate matters, successful hair loss treatment doesn’t come in the form of a quick fix. It’s something that takes time to work – usually a couple of months – and requires consistency and dedication. A lot of people simply quit because they don’t see major results in the first couple of weeks and assume that the treatment doesn’t work .
Hair transplant/surgery. A hair transplant or surgery is the quickest treatment for permanent cases of hair loss, although the most expensive. In pattern baldness, for example, where the top of the head is the most affected area, a hair transplant allows the surgeon to use existing hair to implant it into the bald sections of the head. It works by removing a graft or follicular sample in parts of the head that still have hair (usually this is the back of the head as this area is most resistant to hormonal changes), and placing this graft in the areas that are bald.
The only nonchemical option offered up by the dermatologists I spoke with — short of a surgical hair transplant or platelet-rich plasma therapy, which is like Kim Kardashian’s vampire facial but for your scalp — was the laser comb. First cleared by the FDA in 2009, the HairMax LaserComb is a handheld laser device that is designed to promote hair growth. As the manufacturer explains in a letter to the FDA, “The device provides distributed laser light to the scalp while the comb teeth simultaneously part the user’s hair to ensure the laser light reaches the user’s scalp,” which, in turn, stimulates the hair follicles.

I took a saliva test (where I took samples of my saliva at 4 different times over the course of one day) that tested my cortisol. Cortisol production varies throughout the day with levels normally highest in the morning and lowest in the evening before bed (did you know that too high cortisol at night can be a cause of insomnia!). The advantage of saliva testing is that it takes cortisol levels at different times of the day and lets you know how your cortisol levels vary during the day. My results showed that my cortisol levels were below normal throughout the day. I was obviously struggling with adrenal fatigue and I’m so fortunate to have discovered this.
Consider other factors besides color. Color is important - your wig or hair piece should match your natural hair to look natural. However, consider also texture. You wig should feel like real hair; it should have a smooth and silky feel. For those that need full coverage, choose a wig that bounces to give the illusion of volume. A wig that has a lacing that fits your natural hair also helps in making sure that you have a more natural looking hairline.

Finasteride is available on private prescription in a tablet form. It prevents the hormone testosterone being converted to another hormone called dihydrotestosterone (DHT), which is known to shrink hair follicles. Blocking this action can help the hair follicles to return to their normal size. It usually takes three to six months of daily use to see an effect, and the process starts again if treatment is stopped.

Stay away from tightly bound styles, like braids, buns, or ponytails. Resist twisting or rubbing your hair. And gently wash or brush hair, switching to a wide-toothed comb if necessary to prevent too much pulling at the roots. Hot rollers, curling or straightening irons, hot oil treatments, bleaching, and other chemical processes are other things to avoid.
In addition to your hairstyle, the processes you use on your hair, whether it’s to add color or texture, can have a detrimental effect. For example, harsh chemicals for bleaching and straightening, along with excess heat, can damage and even kill hair follicles, Burg points out. Additionally, excessive chemical treatments applied directly on the scalp can cause inflammation. “Inflammation can damage the follicle, which in turn to can lead to hair loss,” says Maria Halasz, CEO of évolis Professional. To prevent over-processing, she recommends limiting chemical treatments on the scalp to every four to six weeks. Check out these tips for people who use heat on their hair every day.

Instead, you may want to add vitamin D (about $15) to your shopping cart. A vitamin D deficiency can exacerbate hair thinning and make it almost impossible for any over-the-counter product to reverse hair loss, says Dhaval Bhanusali, a dermatologist in New York City, who recommends taking 5,000 international units of D3 a day (and it’s generally beneficial for bone health in women over 40). “There’s also a link between low iron and zinc levels and temporary hair shedding, called [telogen] effluvium,” says Rogers.
The normal cycle of hair goes through a phase of growth and rest. Each individual hair survives for an average of three and a half years. The growth phase of hair generally lasts two to three years, during which time it grows about half an inch a month. This growing phase is called anagen. This is followed by a resting phase called telogen, which lasts for about three to four months. Usually in its fourth year the hair falls out and is replaced within 6 months by a new one.
The cause of female-pattern hair loss is unknown, but doctors said there is a strong genetic component. The risk can come from male or female relatives. Though it looks as if the hair is falling out, that's not really what's happening. Cotsarelis said hair follicles are becoming smaller and producing hairs that may be so small that you can't see them.  Women tend to retain more normal, thick hairs than balding men do.
Traumas such as childbirth, major surgery, poisoning, and severe stress may cause a hair loss condition known as telogen effluvium,[19] in which a large number of hairs enter the resting phase at the same time, causing shedding and subsequent thinning. The condition also presents as a side effect of chemotherapy – while targeting dividing cancer cells, this treatment also affects hair’s growth phase with the result that almost 90% of hairs fall out soon after chemotherapy starts.[20]

The scalp contains a natural oil called sebum, which helps keep the skin lubricated. Sebum is produced by the sebaceous glands. Sometimes these glands work overtime and produce too much oil, leading to a greasy scalp. Greasy hair can look dull, limp, and lifeless, and it may be more difficult to manage. To treat greasy hair, try washing with a gentle shampoo that is specially formulated to control sebum.
