Hair lost to male-pattern and female-pattern baldness won't grow back on its own, but there are medications that can help slow hair loss and even regrow hair. Minoxidil (Rogaine) is a topical medicine that is available over the counter to treat men and women. Finasteride (Propecia) is a pill that is available to men only by prescription. Injectable cortisone may also help regrow hair lost to certain conditions.
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.
While there is no catch, finasteride doesn’t completely cure male pattern baldness. Instead, it blocks the hormone linked to hair loss in men (DHT) and is only effective for as long as you take the medication. No matter how successful your treatment is and regardless of how much hair you’ve managed to grow back, if you stop taking finasteride abruptly, you’re not going to like the result. More often than not, the hair you grew back will fall out and the balding process as a whole will resume where it left off.
Hair loss vitamins such as Biotin, Niacin (Vitamin B3) and Vitamin C, and minerals for hair loss such as Zinc and Iron, provide essential hair nutrients to nourish healthy and longer hair. Eating enough of these key hair growth vitamins can help prevent hair loss in both men and women. Although some causes of hair loss, such as chemotherapy, illness and medication, may only be moderately affected by a good hair loss diet, in many cases men and women can see great results after only 3-4 months eating more vitamins and minerals for hair growth. 
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.
Correct ferritin levels maximize your hair’s “anagen” or “growing” phase and encourage your hairs to grow to their full length. When you aren’t getting enough iron through your diet, your body takes ferritin stored in non-essential tissue, like your hair bulb, and gives it to essential tissue, such as your heart. Because your hair bulb is where all your hair cells are produced, this leeching of ferritin can cause your hair to shed before it reaches its maximum length.
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.
Disruptions in the normal length of each phase, which can cause hair loss and hair thinning, may be the result of a number of internal and external stimuli. These are also what we call the triggers and causes of your hair loss. As a quick example, dieting can leave the body stressed and in need of important nutrients. Because of this stress, hair growth may be cut shorter than usual and there is an early onset of telogen or shedding of hair.

Contact immunotherapy. Another drug that can be administered for cases of alopecia areata is contact immunotherapy and is recommended for severe cases. Diphenylcyclopropenon (DPCP) is applied on the scalp every week, and the dosage of the drug is increased over time until a mild allergic reaction is observed, which signals that the drug is taking effect. Regrowth may be observed within three months from the beginning of treatment.
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.”

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]
The other main hair-loss treatment that was recommended by all four dermatologists I interviewed is finasteride, often called by its brand name Propecia. This FDA-approved medication is only available with a prescription, but these days, it’s found as a generic and ordered online after a virtual consultation, through start-ups like Hims, Keeps, and Lemonaid.

Some hair loss treatments can cause side effects. Regaine for women can cause headache, skin irritation and changes in the colour or texture of your hair. It is normal to notice increased shedding during the first two weeks of treatment with Regaine. This indicates that the treatment is working. If you find that you are shedding an unusual amount of hair after the first 14 days of treatment, stop using Regaine and ask your doctor for advice.
“I think their effectiveness is not as significant as finasteride or minoxidil,” says Dr. Wolfeld, “however, it’s something that can be used quite easily by patients at home. If they use it two or three times a week, I tell them it can help to thicken their hair.” Results can take up to 18 months to show up, so Dr. Wolfeld stresses that patience is a virtue.
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.
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).

Polycystic ovary syndrome (PCOS) is another imbalance in male and female sex hormones. An excess of androgens can lead to ovarian cysts, weight gain, a higher risk of diabetes, changes in your menstrual period, infertility, as well as hair thinning. Because male hormones are overrepresented in PCOS, women may also experience more hair on the face and body.
According to the idea of Ladies Home Journal, frizzy hair can be improved with silicone-based products, which can help fight off frizz while smoothing down the cuticle. Moreover, frizz-fighting products containing certain types of proteins, for example, soy or wheat protein can help with hydration. Lastly, there is something that should not be done in order not to worsen the condition, such as brushing dry hair or over- process hair [4].
1. Collagen powder. Preliminary studies suggest that marine-sourced collagen may stimulate hair growth, says New York City dermatologist Yoon-Soo Cindy Bae. Though more research is needed, participants in studies reported thicker hair after three to six months of daily use. Crushed Tonic Original Powder ($105) easily mixes into coffee, tea, and water.

Dietary supplements are not typically recommended.[30] There is only one small trial of saw palmetto which shows tentative benefit in those with mild to moderate androgenetic alopecia.[30] There is no evidence for biotin.[30] Evidence for most other produces is also insufficient.[37] There was no good evidence for gingko, aloe vera, ginseng, bergamot, hibiscus, or sorphora as of 2011.[37]
Has your doctor told you that your blood sugar levels are too high? Low thyroid is one potential cause of diabetes, and it may be your red flag to have your thyroid re-evaluated. When my doctor once mentioned that my blood sugar was at the high pre-diabetic level and suggested starting diabetes medication, I asked for 6 months to try replacing my regular multivitamin with this one Designs for Health Metabolic Synergy (created by a nationally prominent doctor specializing in blood sugar) and by my follow-up appointment my blood sugar was completely normal and diabetes medication was not needed (what a relief).

Hair concealers and hair fibers. These are one of the newest cosmetic answers to hair loss. As the name suggests, these products are applied on the scalp or hair to camouflage hair loss and give the appearance of fullness to thinning hair. Some of these are applied directly on the scalp, while others (hair fibers) are attached to the hair, much like hair extensions, to add volume.


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.
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.
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
Post surgery care is important if you've undergone a hair transplant or surgery. Expect some swelling of the face and on the scalp a couple of days after the procedure. To fast track hair growth, you may be asked to use Minoxidil or Finasteride. Saline is applied on the grafts for a few days, while you will be prescribed to use a diluted shampoo that is softer and less harsh on the scalp. Hair growth in the transplanted areas becomes visible in three - six months.

The dermatologist also will carefully look at your scalp and hair. During an exam, the dermatologist may pull on your hair. Sometimes a dermatologist needs to pull out a hair to get the necessary evidence. And sometimes a dermatologist needs to look at the hair on the rest of your body to see whether there is too little or too much hair in other areas.
The HairMax Ultima 12 LaserComb ($395) makes for a great addition to any hair loss regimen — provided you can afford it. Dr. Wolfeld notes that it’s a popular option in his practice. “Some people like the action of combing something through their hair,” he says. “They find that to be a little bit easier to do as part of their routine in the morning.” Dr. Khadavi also recommends using a laser treatment of some kind in conjunction with other treatments. “Lasers do help in stimulating the hair into the growth phase. We don’t know the exact mechanism of how it works, but it definitely helps.”

When it comes to hair health, what you put in your body is just as important as what you put on your hair. Maintaining a healthy and balanced diet becomes crucial as soon as you notice hair fall. Foods that are rich in Zinc, Iron, Vitamins A, B complex, Vitamin C, Vitamin E, omega-3 fatty acids, and proteins should be consumed. These foods by themselves may go a long way in curbing hair fall as more often than not, hair fall is directly related to a vitamin/mineral deficiency. A healthy diet will also help keep your hair moisturized and nourished, leading to lesser hair fall, fewer split ends, and curbed breakage.
Back in the 17th century, men were told that coating their balding heads with chicken faeces would help them regain a full head of long glossy locks. While we might have moved on somewhat since then, we still don’t fully understand the science behind hair loss and hair regrowth and, unfortunately, there are still some very common myths about hair remedies that we are far too quick to believe. 
Trichotillomania (pronounced: trik-o-til-uh-MAY-nee-uh). Trichotillomania is a psychological disorder in which people repeatedly pull their hair out, often leaving bald patches. That can leave areas of baldness and damaged hairs of different lengths. People with trichotillomania usually need help from a therapist or other mental health professional before they can stop pulling their hair out.
As they age, men tend to lose the hair on top of their head, which eventually leaves a horseshoe-shaped ring of hair around the sides. This type of hair loss is called male-pattern baldness. It's caused by genes (from both parents -- the idea that men take after their mother's father is a myth) and it's fueled by the male hormone, testosterone. In female-pattern baldness, the hair loss is different -- it thins throughout the top of the scalp, leaving the hair in front intact.

Tinea is the medical word for fungal infection, and capitis means head. Tinea capitis is fungal infection of the scalp that for the most part affects school-age children. Tinea capitis is more common in black African or African-American scalps. This condition is rare in healthy adults. Bald spots usually show broken-off hairs accompanied by a dermatitis. Oral antifungals can penetrate the hair roots and cure the infection, after which hair grows back. Sharing hats or combs and brushes may transmit tinea capitis.

It’s also possible that some of Harklinikken’s users are women whose hair would have grown back even if they’d done nothing. Many women who arrive in a dermatologist’s office with prior diagnoses of female pattern hair loss actually have what’s called telogen effluvium. That’s a period of acute shedding of hair — meaning up to 60 percent of hair — three months after a triggering event like pregnancy, significant weight loss or starting or stopping hormone medications.
Also known as Rogaine, this over-the-counter (OTC) medication can be used for men or women with alopecia areata or androgenic alopecia. This drug comes in foam or liquid form and is spread on the scalp each day. It may cause more hair loss at first, and new growth may be shorter and thinner than before. You may also need to use it six months or more to prevent further loss and promote regrowth.

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.
"Firstly, even the very good ones won’t get to the root of the issue - pardon the pun - and prevent or treat male or female pattern baldness which is caused by genetics, nor deal with hormonal issues at the heart of female hair loss. But they can help make the hair you do have stronger and healthier. And they can be useful in putting a hair loss regime in place, along with medication like Minoxidil or Finasteride and/ or a hair transplant.
