The third and fourth stages are known as telogen and exogen, respectively. In telogen, the hair is supposed to be at "rest" until it finally detaches itself from the follicle and enters the exogen or shedding stage. Once the hair is detached from the follicle, the follicle remains inactive for about three months, after which a new cycle begins again.
The follicles on the sides of the scalp are more genetically resistant to DHT, which is why male pattern baldness often results in a “crown” of hair. But its downsides are serious. “With women, finasteride is not an option,” says Dr. Wolfeld. “It’s not FDA-approved for women to take, so we don’t prescribe it.” In fact, due to the drug’s effect on hormone levels, pregnant women are advised to not even touch broken or crushed tablets.
Certain foods have also been found to aggravate or worsen hair fall, such as sugar, which triggers the overproduction of the male hormone, androgen, which in turn causes the hair follicles to shrink in size and for hair to fall out or stop growing. Fish products that are known to contain high levels of mercury like tuna, mackerel and swordfish can also cause hair weakening and excessive hair fall. Studies have also found that fried foods are associated with the production of high levels of DHT.
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]
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.
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.

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.

"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.


"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."
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.

Finally, if these tests come back normal, your dermatologist may suggest a scalp biopsy of a couple of two-millimeter sections taken from your scalp under local anesthesia ($400 and up). It can determine whether genetic hair loss, telogen effluvium (a condition in which hair falls out from stress or rapid weight gain), or a disease (such as lupus) is the cause of your shedding, and your dermatologist can treat you accordingly.

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.


One is how much emphasis the company places on compliance, the major stumbling block in the efficacy of any treatment, said Dr. Senna, an author of studies on the subject. Prospective users are questioned about their ability to stick to a regimen because the extract must be applied every day, and they are told that the more conscientious they are, the better. Users are also reminded and encouraged with regular check-ins.

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. 

Chemotherapy is also one of the primary causes of balding among cancer patients, men and women alike. While not all chemotherapy treatments result in hair loss, some that involves the use of drugs like Altretamine, Carboplatin, Docetaxel, and Idarubicin can cause hair thinning and hair fall. In such cases, the hair loss varies from person to person and the dosage of drugs administered. Hair fall doesn't occur at once, but rather after several weeks of treatment until hair fall rate increases after one or two months of exposure to chemotherapy. Radiation therapy as part of cancer treatment can also result into hair loss but typically only in areas where the radiation is targeted.

Daily hair counts are normally done when the pull test is negative. It is done by counting the number of hairs lost. The hair from the first morning combing or during washing should be counted. The hair is collected in a clear plastic bag for 14 days. The strands are recorded. If the hair count is >100/day, it is considered abnormal except after shampooing, where hair counts will be up to 250 and be normal.[citation needed]
