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.
Surgical options, such as follicle transplants, scalp flaps, and hair loss reduction, are available. These procedures are generally chosen by those who are self-conscious about their hair loss, but they are expensive and painful, with a risk of infection and scarring. Once surgery has occurred, six to eight months are needed before the quality of new hair can be assessed.
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.
Here's what you might be wondering about: unwanted sexual side effects. Remember that finasteride works by blocking DHT, and DHT is a male sex hormone and is also a form of testosterone – this sex hormone just happens to also be linked to hair loss, unfortunately! In clinical tests, approximately 2% of the people who take finasteride reported unwanted sexual side effects like decreased libido, difficulty getting or maintaining an erection, and trouble ejaculating. Of that 2%, half of them reported that the side effect went away after taking the medication for three months, and everyone reported that the side effects went away as soon as they discontinued the medication. Still, that leaves less than 1% of guys taking finasteride with a chance of developing persistent sexual side effects.
Other causes for hair loss or hair thinning can be stress, illness, poor diet, hormone imbalance or your body going into shock. Certain diseases and intensive medical treatment such as chemotherapy are also likely to result in hair loss, but it is best to consult your GP if you go bald at an alarmingly fast rate, especially if you have no family history of male pattern baldness.
"My hair began to thin when I was 28 years old. Now I am 44 and the top of my head is bald. Recently, I considered using medicine to treat my hair loss and see if any hair would regrow. After reading the literature and talking to my doctor, I decided not to take medicine because it is unlikely to make a huge difference in my hair—and I don't want to take medicine forever!"
Hair-fiber powders: Colored, powdery fiber sprinkles are commercially available and may work to camouflage balding areas. These colored sprinkles have special properties that help them attach to hair and give a fuller appearance. Toppik is one manufacturer of these products and can be found online. These cosmetic products are available without a prescription, are fairly inexpensive ($20-$40 range), and quite safe with minimal risk. Often these may be used in addition to medical treatments like Rogaine, Propecia, and hair transplants, and they are a great temporary measure to tide one over for special occasions.
Drink plenty of water and keep yourself well hydrated. Cut down on smoking and alcohol drinking which makes you dehydrated. If you are not consuming enough water to meet your body’s daily oxygen requirements, the cells responsible for hair growth will not be able to grow and reproduce. This will make your hair brittle, withered and very dry. Not drinking enough water can stop the natural growth cycle of your hair. So drink plenty of water to get a long, shiny and luscious mane!
You might love the way your hair looks after using your curling iron or straightener, but the damage it causes to your strands might leave your hair thinning. James warns that setting your tools to 450ºF or higher or keeping your hair on the hot tool for too long can burn your hair and potentially cause it to break off. “Set your flat iron or curling iron on medium heat and work with smaller sections, which require less time on the hot tool.” To ease yourself off, try these ways you can curl your hair without a curling iron.

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.

Managing hair loss is just as important as treating it. Now that we've talked about the different treatment options and cures available to reverse hair loss and promote increased growth, let's talk about how you can manage your condition and at the same time prevent further hair loss. The first is more psychological, while the second is more practical.

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.

If you’re a gentleman who’s been noticing a receding hairline or is worried about balding, the first step is to schedule a visit with a doctor or dermatologist and make sure your hair loss isn’t a sign of a more serious health issue. “Not all hair loss is male-pattern hair loss,” explains Dr. Marc Glashofer, a board-certified dermatologist specializing in hair loss and practicing in northern New Jersey. A thyroid disorder, an autoimmune disease, or even a scalp issue could be making you look like Bruce Willis in Die Hard 2. But most hair loss is androgenetic alopecia, also known as male-pattern baldness, and fortunately (or not, depending on your perspective), it’s just a symptom of getting older.
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.
The noticeable hair loss was a red flag for me that I needed to get to my doctor for thyroid testing. I’m on the natural desiccated thyroid Nature-throid plus a compounded time-release T3. My doctor did comprehensive testing including the essential thyroid tests TSH, Free T4, Free T3, Reverse T3, and thyroid antibodies. Turned out my Free T3 was middle of the range. I personally feel terrible when my Free T3 is low or even middle of the range. Optimal Free T3 for my body is when it reaches top quarter of the normal range, so adjusting my thyroid medication dosage was an essential piece to my thyroid hair loss. There are many different thyroid medication options. Finding a doctor open the treatment options to find what is right for you is key.
When women have a hormonal disorder that causes high levels of testosterone, including polycystic ovary syndrome (PCOS), they may experience thinning of hair on the scalp. Often these conditions are also associated with acne, irregular periods, and hair growth in areas typically seen in men, says Joshua Zeichner, MD, director of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York City. “Over-the-counter supplements, such as Nutrafol, can help provide the follicles with the necessary building blocks for healthy hair production,” he says. These are other sneaky reasons your hair is thinning.
Herbal hair supplements are designed to “supplement,” or work together with, a healthy diet, not replace it. However, it’s also important to recognize that the fast pace of life doesn’t always allow for making meals from scratch every day. If you find it hard to meet the recommended daily amounts nutrients because of a tight schedule, you’re definitely not alone.
Alopecia areata is an autoimmune disorder also known as "spot baldness" that can result in hair loss ranging from just one location (Alopecia areata monolocularis) to every hair on the entire body (Alopecia areata universalis). Although thought to be caused by hair follicles becoming dormant, what triggers alopecia areata is not known. In most cases the condition corrects itself, but it can also spread to the entire scalp (alopecia totalis) or to the entire body (alopecia universalis).
Why? Unwanted hair growth (sideburns, for example) is a reported side effect of minoxidil. The belief is that a higher concentration of minoxidil would result in more unwanted hair, which is why women are instructed to use it less often. However, the study in Skin Therapy Letter reports that unwanted hair was more common in 2 percent minoxidil solutions than 5 percent, and women are instructed to use Rogaine’s 2 percent solution twice daily — so what gives?
A little farther up the follicle is the mysterious feature called the bulge. That's where follicle stem cells live. When they get the right set of chemical signals, these self-renewing cells divide. They don't divide like normal cells, in which both halves become new cells that keep splitting and developing. Only one half of the follicle stem cell does that. The other half becomes a new stem cell, and stays put for future regeneration.
It can be proven that Follixin truly is a revolutionary hair loss product simply by looking at the results of clinical trials or the opinions from tablets’ users who took them on a daily basis. Follixin rejuvenates clogged pores and widens the hair follicles, strengthens them at their root and thickens the sheath of each hair follicle. As a result the tablets restore previously lost hair and protect existing hair internally.

Beyond that, things get more controversial, with some doctors saying there's inadequate evidence for other treatments. Saxena thinks there is enough scientific evidence to support some of the alternatives and recommends them to patients. But they are not for women on tight budgets. There's Nutrafol, a "nutraceutical" that costs about $80 a month. Women can also get injections in the scalp of platelet-rich plasma made from their own blood. The first four treatments cost about $2,000 at Saxena's practice in Fort Washington or Lansdale. Maintenance injections, done every three to six months, cost $515 each. Women can also buy Theradome, a light-emitting helmet, for $895 online.  Saxena, who has hair loss herself, said she has had the injections and currently uses minoxidil, spironolactone, and Nutrafol.
Traction alopecia - certain hairstyles such as when you pull on your hair tightly can cause scarring of the hair follicles. If pulling is stopped before scarring to the scalp then your hair will grow back normally. Nervous habits such as continual hair pulling or scalp rubbing can also cause scarring and ultimately permanent hair loss. Excessive shampooing and blow-drying can also cause hair loss.
Hair changes about as fast as grass grows, which is to say it’s extraordinarily slow and not visible to anyone checking impatiently in the mirror every day. But during regular follow-up appointments, Harklinikken uses high-tech equipment to photograph and magnify the scalp and count new hairs and active follicles, which motivates users to adhere to the regimen. Too many people give up on treatments like Rogaine and low-level-light devices before they’ve had a chance to work, Dr. Senna said.
Hair transplantation is usually carried out under local anaesthetic. A surgeon will move healthy hair from the back and sides of the head to areas of thinning. The procedure can take between four and eight hours, and additional sessions can be carried out to make hair even thicker. Transplanted hair falls out within a few weeks, but regrows permanently within months. Hair transplants, takes tiny plugs of skin, each which contains a few hairs, and implants the plugs into bald sections. The plugs are generally taken from the back or sides of the scalp. Several transplant sessions may be necessary.[33]
Vigorous styling and hair treatments over the years can cause your hair to fall out. Examples of extreme styling include tight braids, hair weaves or corn rows as well as chemical relaxers to straighten your hair, hot-oil treatments or any kind of harsh chemical or high heat. Because these practices can actually affect the hair root, your hair might not grow back.
