Finasteride (Propecia) is used in male-pattern hair loss in a pill form, taken 1 milligram per day. It is not indicated for women and is not recommended in pregnant women. Treatment is effective starting within 6 weeks of treatment. Finasteride causes an increase in hair retention, the weight of hair, and some increase in regrowth. Side effects in about 2% of males, include decreased sex drive, erectile dysfunction, and ejaculatory dysfunction. Treatment should be continued as long as positive results occur. Once treatment is stopped, hair loss resumes.[30]
If you do decide to start treatment to save your hair, a good place to start is with minoxidil, more commonly known as Rogaine. Don’t expect this hair-loss treatment to create luscious locks; minoxidil is better at slowing down or preventing more loss rather than promoting hair growth. But, according to Dr. Amy McMichael, professor and chair of Wake Forest Baptist Medical Center’s Department of Dermatology, it is effective “if used as recommended, with evidence of improvement seen around six to nine months.” Simply massage the foam or solution into your scalp once or twice daily, and for best results, use a formula with 5 percent concentration.
Cyclosporine is used to suppress the immune system in psoriasis and other immune-mediated skin conditions. Although cyclosporine helps hair regrowth in alopecia areata, the risks of using it may outweigh the benefits, as oral cyclosporine can suppress the immune system and increase the risk of serious infection. Other common adverse effects are hypertension and renal impairment, but these are usually reversible.
Women lose hair on an inherited (genetic) basis, too, but female pattern hair loss tends to be more diffuse, with less likelihood of the crown and frontal hairline being lost. Although some women may notice hair thinning as early as their 20s, the pace of hair loss tends to be gradual, often taking years to become obvious to others. There seems to be a normal physiologic thinning that comes with age and occurs in many women in their early to mid-30s. More women have underlying causes of hair loss than men. These include treatable conditions like anemia and thyroid disease and polycystic ovary syndrome (PCOS). These conditions are diagnosed by blood tests along with a historical and physical evidence. Although a few studies have suggested that baldness may be inherited through the mother's family genes, these theories require further testing. Current studies are inconclusive. Although not indicated for female pattern balding, spironolactone (Aldactone) has had some success in treating this condition.
Once male-pattern baldness starts, it’s not going to stop until every last hair on your head has shrunk or shed, though the rate at which this happens differs from person to person and depends on genetics. And since the grind of hair loss is unending, it’s important to start treatment as soon as your hairline starts bothering you. If you’re looking for a more quantitative metric, Dr. Paul McAndrews, clinical professor of dermatology at the USC School of Medicine and member of the International Society of Hair Restoration Surgery, assures me that “you have to lose half your hair before the human eye can tell.” (Of course, if you don’t care about losing your hair and are fine with going full Prince William and shaving your head, go for it. We’ve got some recommendations for razors and hair trimmers to help you out on that front.)
Drinking warm water with lemon every morning and before meals has definitely helped increase my stomach acid. I drink it through a straw (I purchased an inexpensive set of stainless steel straws) to prevent damage to the enamel of my teeth. You can also try adding one or two tablespoons of Bragg Organic Unfiltered Apple Cider Vinegar with the ‘Mother’ mixed in water before meals.
Ms. Imhof, who lives in Land O’Lakes, Fla., was skeptical. The company’s before and after photos seemed too good to be true. But she went for a consultation and made the cut. (Harklinikken’s products are not available to anyone with autoimmune illnesses like alopecia or baldness from scarring, or anyone who is unlikely to see at least a 30 percent increase in growth.)
DR. WRIGHT: If stomach acid is low, protein isn’t efficiently digested – and hair and nails are made up of… protein! If we are deficient in protein, our bodies know that we can live without hair or nail proteins, but we can’t survive without heart muscle proteins or other important body proteins. So if we are short in supply of protein, the hair or nails are the first to go.
Anagen effluvium - is hair loss due to treatment with chemotherapy medicines. These medicines target rapidly dividing cells, so affects the actively growing hair cells. Hair grows back after the treatment is finished. This type of hair loss also occurs with radiation therapy but it is localized to the area of treatment. so if treatment is in the hip area you will lose hair in that area but not the hair on your head.

1. Hair color. Anytime you dye your hair, you’re increasing the diameter of each strand, which can help add volume when your hair is sparse and fine. As a general rule, ask your colorist to make sure highlights are finer at the top of the head, where hair is the thinnest, and more intense at the bottom, where it’s thickest, says Eva Scrivo, a hairstylist and the owner of the Eva Scrivo Salon in New York City. And beware: A color that contrasts with your scalp (blonde tones if your scalp is dark, deep brunettes if your scalp is light) will make any visible scalp more obvious.
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.
Another type of baldness that goes with hair styling can be permanent: Wearing your hair in a style that pulls too tightly can cause something called traction alopecia. Traction alopecia can permanently damage the hair follicles if you wear a style that pulls on your hair for a long time. if you are getting your hair styled and it hurts, ask the stylist to redo it so that it is no longer painful. Pain is a sign of too much traction on the hair.
All men and women will be affected by patterned hair loss at some stage in their lives. While the majority of men have developed temporal recession by their mid 20s and noticeable balding by their mid 50s, for most women, hair loss is mild and only occurs later in life. However, when hair loss is premature or severe, it can cause distress. A range of treatments is available to slow or reduce hair loss, and stimulate partial regrowth
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.
Minoxidil: This medicine is applied to the scalp. It can stop hairs from getting thinner and stimulate hair growth on the top of the scalp. The U.S. Food and Drug Administration (FDA) has approved minoxidil to treat hair loss. It is the only hair re-growth product approved for men and women. A dermatologist may combine minoxidil with another treatment.
There are few scientifically proven and FDA-approved treatments for hair loss. There are thousands of unproven claims and products to help with hair regrowth. Many conditioners, shampoos, vitamins, and other products claim to help hair grow in some unspecified way. Nioxin has been a popular brand of shampoo for hair loss, but there is no compelling evidence showing it is any more effective than regular shampoos. These products are usually harmless but generally not scientifically proven and therefore potentially useless. To slow down hair loss, there are at least four potentially effective, basic options. These include medications like Minoxidil, and Propecia, which are for long-term use. Stopping these drugs does not seem to worsen or exacerbate the prior hair loss. The patient will simply revert to the state he would have been in had he never started treatment.
Of course, there are plenty of men who wish desperately to restore their youthful locks, and a few — we can think of one powerful one — who cling to elaborate comb-overs, but many balding men simply clip their hair short and go on with their lives. Dermatologists say hair loss is emotionally harder for women, who are often deeply embarrassed by thinning hair even though it's quite common. By the time they reach 50, about 40 percent of women are experiencing what's known as female-pattern hair loss, said Gopal Patel, a dermatologist with Aesthetic Dermatology Associates in Media. Women of African descent struggle with even more conditions that can damage hair follicles and cause bald spots.
Medications and vitamins: Cancer chemotherapy, which attacks hair follicles in its attempt to kill all fast-growing cells around the body, is a well-known reason for hair loss. Other medications’ side effects include hair shedding as well, such as some that treat high blood pressure and gout (a painful joint condition caused by a buildup of uric acid). Excessive levels of vitamin A also contribute.

Harklinikken (“hair clinic” in Danish) inspires great loyalty. Four out of five users come as referrals from satisfied customers, said Lars Skjoth, the company’s founder and chief scientist. The results are certainly compelling. After four months of daily application — that is, working the tea-colored tonic into the hair section by section, then letting it sit on the scalp for six hours — most users regain at least 30 percent of lost density, and some as much as 60 percent, according to company figures.
The pull test helps to evaluate diffuse scalp hair loss. Gentle traction is exerted on a group of hairs (about 40–60) on three different areas of the scalp. The number of extracted hairs is counted and examined under a microscope. Normally, fewer than three hairs per area should come out with each pull. If more than ten hairs are obtained, the pull test is considered positive.[27]
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.
Surgery: Men tend to be better candidates for surgical hair-replacement techniques because their hair loss is often limited to one or two areas of the scalp. Procedures include grafting, which transplants from one to 15 hairs per disc-shaped graft to other locations. Scalp reduction removes bald skin from the scalp so hair-covered scalp can be stretched to fill in the bald areas. Side effects include swelling, bruising and headaches.

"The majority of men lose their hair not through stress, or bad diet, or lack of sleep, but through the genetic trait of male pattern baldness which is hard to treat through shampoos or supplements alone. Women lose their hair for very different reasons, but the argument still stands that a lot of the hair loss products on the market are just offering false hope. That said, there are a few that really work."
Taking hair supplements can be helpful for anyone who is experiencing hair loss or hair thinning. Dendy Engelman, MD, a board-certified dermatologic surgeon at Medical Dermatology & Cosmetic Surgery in New York City, previously recommended Nutrafol, a research-backed hair supplement, to Prevention. "This uses highly concentrated botanicals to address every stage of the growth cycle," she says. Nutrafol's hair supplements include vitamin E and ashwagandha (an adaptogen that helps balance cortisol levels in the body), among others. 

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.
Alopecia areata - starts suddenly and causes hair loss in patches anywhere in the body in children and young adults. This condition is also known as ‘spot baldness’. This condition is observed to run in families and experts believe this condition could be the result of autoimmune disease, where the immune system of the body mistakenly attacks the hair follicles.

Harklinikken does not advertise, but the 25-year-old multinational company is beginning an aggressive expansion into the $3.6 billion hair-loss market in the United States, meaning you’re likely to hear a lot more about it. A New York clinic opened in June inside the Core Club in Midtown (you don’t need to be a member to get an appointment); and in August, Harklinikken consultations became available at some 70 Women’s Care Florida obstetrics and gynecology clinics. (Roughly 75 percent of the company’s 50,000 active users are female.)
