Periods of prolonged or severe illness can affect the hair. “As with extreme stress and extreme diets, this also comes down to the body preserving its energy balance and shutting down non-essential functions in order to battle the illness more effectively,” Berg says. “In fact, physicians have used an inspection of the fingernails and hair quality as part of standard examinations of overall health for many years. Changes in these features provide some clues about the length and severity of illness.” Other diseases, such as diabetes and lupus, can also cause hair loss. Check out these other things your hair can reveal about your health.
People have between 100,000 and 150,000 hairs on their head. The number of strands normally lost in a day varies but on average is 100.[8] In order to maintain a normal volume, hair must be replaced at the same rate at which it is lost. The first signs of hair thinning that people will often notice are more hairs than usual left in the hairbrush after brushing or in the basin after shampooing. Styling can also reveal areas of thinning, such as a wider parting or a thinning crown.[citation needed]
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.

Trichotillomania, classified as an “impulse control disorder,” causes people to compulsively pull their hair out. “It’s sort of like a tic, the person is constantly playing and pulling their hair,” says Dr. Glashofer says. Unfortunately, this constant playing and pulling can actually strip your head of its natural protection: hair. Trichotillomania often begins before the age of 17 and is four times as common in women as in men. 

Another method is to wear a hat or a hairpiece—a wig or toupee. The wig is a layer of artificial or natural hair made to resemble a typical hair style. In most cases the hair is artificial. Wigs vary widely in quality and cost. In the United States, the best wigs—those that look like real hair—cost up to tens of thousands of dollars. Organizations also collect individuals' donations of their own natural hair to be made into wigs for young cancer patients who have lost their hair due to chemotherapy or other cancer treatment in addition to any type of hair loss.
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!

What to do: Like anemia, simple supplementation should help the problem. So can dietary changes. Find natural vitamin B in fish, meat, starchy vegetables, and non-citrus fruits. As always, eating a balanced diet plentiful in fruits and vegetables as well as lean protein and “good” fats such as avocado and nuts will be good for your hair and your overall health.
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.
Menopause is the time in a woman's life when menstrual periods permanently stop, also called the "change of life." Menopause symptoms include hot flashes, night sweats, irregular vaginal bleeding, vaginal dryness, painful intercourse, urinary incontinence, weight gain, and emotional symptoms such as mood swings. Treatment of menopausal symptoms varies, and should be discussed with your physician.
Minoxidil (Rogaine). This is an over-the-counter (nonprescription) medication approved for men and women. It comes as a liquid or foam that you rub into your scalp daily. Wash your hands after application. At first it may cause you to shed hair as hair follicles. New hair may be shorter and thinner than previous hair. At least six months of treatment is required to prevent further hair loss and to start hair regrowth. You need to keep applying the medication to retain benefits.
Dull hair will be the next one on the list of common hair problems that are mentioned in this article. The dull hair will not only make you uncomfortable but also make you look older than your real age. Dull hair can be caused by chemical damage, heat styling damage, improper styling techniques, and sometimes environmental soils as well as stresses, which can roughen the hair’s cuticle.
Scalp reduction is the process is the decreasing of the area of bald skin on the head. In time, the skin on the head becomes flexible and stretched enough that some of it can be surgically removed. After the hairless scalp is removed, the space is closed with hair-covered scalp. Scalp reduction is generally done in combination with hair transplantation to provide a natural-looking hairline, especially those with extensive hair loss.

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.
There are several different types of medication you can buy to help treat hair loss. Procepia and Finasteride are currently the only approved drugs you can take that will effectively treat hair loss. The active ingredient in both treatments (finasteride) works by blocking DHT (the male hormone dihydrotestosterone) that causes hair loss by shrinking hair follicles on your scalp. It has been proven to lead to hair regrowth or to stop hair loss in around 9 out of 10 men in clinical trials. 
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.
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.
Finasteride inhibits an enzyme that converts testosterone to DHT, or dihydrotestosterone, the hormone that causes hair loss in men, and unlike minoxidil, this drug can actually help hair grow back, as well as prevent further loss. All you have to do is take one pill a day, and according to Dr. Evan Rieder, dermatologist in the Ronald O. Perelman Department of Dermatology at NYU Langone Health, two-thirds of men taking this treatment will see improvements in hair density over time.
And though this treatment appears to be safe and somewhat effective, it’s hard to tell who will react well to this low-level light therapy, which is why the doctors I spoke with were hesitant to fully endorse it. “We’re not sure what the optimal power is, what the optimal wavelength is, we don’t even really know the mechanism of action of how this is working,” says Rieder. Plus, it doesn’t work on everyone. “There are subpopulations of patients who do respond to low-level laser light, but this is not easily predictable,” explains McMichael, though she adds that the risk of using the LaserComb is low.

“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.
NATURAL INGREDIENTS BACKED BY SCIENCE: We all know how biotin alone can do wonders for your hair, but most aren't aware that it also interacts incredibly well with other ingredients to boost its effectiveness. Our team of experts has formulated a natural, synergistic blend that combines several essential vitamins, minerals, and amino acids that work in conjunction to create a truly superior blend for maximum results.

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.

As always, eating a balanced diet plentiful in fruits and vegetables as well as lean protein and “good” fats such as avocado and nuts will be good for your hair and your overall health.
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.”

As I mentioned before, the causes of hair fall are innumerable, and so it becomes crucial to get to the root of the problem. The best way to go about dealing with the problem would be to get the correct diagnosis to begin with. This can be made simpler by finding the areas where thinning is most prominent and also monitoring how much hair you are losing whenever you comb or shampoo. Consult a physician to find out whether you have any underlying medical issues causing the hair fall.
The best fix by far for replacing lost hair is a transplant. Back in the day, docs used plugs that resembled cornrows (definitely not natural looking). Today, guys have more options. You can go for “the strip method” where a doctor surgically removes a strip of hair from the back of your head, dissects every hair graft under a microscope, and then plants the individual grafts onto hair-thin areas of your scalp with tiny incisions.
Just letting go is possibly the most challenging of the available options. It’s also the cheapest and ultimately the most effective in the struggle with hair loss. Given the imperfections of surgical, medical, and technological options, there are many who advocate simple acceptance. (BaldRUs.com is one of several sites devoted to embracing the scalp's natural fate.) What's more, the health benefits of happier mirror time -- and fewer years of harmful anxiety -- just might offset the loss of those Samson-like powers.

Cosmetic procedures, such as shampooing too often, perms, bleaching, and dyeing hair can contribute to overall hair thinning by making hair weak and brittle. Tight braiding, using rollers or hot curlers, and running hair picks through tight curls can also damage and break hair. However, these procedures don't cause baldness. In most instances hair grows back normally if the source of the problem is removed. Still, severe damage to the hair or scalp sometimes causes permanent bald patches.
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.
Hello,alopecia means patterned hair loss.if it is alopecia areata its patchy hair loss for which toical creams and intralesional injections would help.if it is androgenic alopecia that is male baldness treatment depends on grade of alopecia ranging from topical medications to hair transplant.prp treatment is one of the natutal treatment available for alopecia in which plasma from patient is taken and injected into scalp.underlying causes too should be evaluated before starting treatment.
“The most common cause of hair loss in both men and women is androgenetic alopecia, which is genetic pattern hair loss,” explains Dr. Michael B. Wolfeld, a board-certified plastic surgeon and an assistant clinical professor of plastic surgery at the Icahn School of Medicine at Mount Sinai Hospital in New York. The root cause of this type of hair loss is dihydrotestosterone (DHT), a byproduct of testosterone that shrinks certain hair follicles until they eventually stop producing hair.

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.”
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]
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.
