A substantially blemished face, back and limbs could point to cystic acne. The most severe form of the condition, cystic acne, arises from the same hormonal imbalances that cause hair loss and is associated with dihydrotestosterone production. Seborrheic dermatitis, a condition in which an excessive amount of sebum is produced and builds up on the scalp (looking like an adult cradle cap), is also a symptom of hormonal imbalances, as is an excessively oily or dry scalp. Both can cause hair thinning.
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.

Poor nutrition. Not eating enough healthy food can contribute to hair loss.

And some athletes are at higher risk for hair loss because they may be more likely to develop iron-deficiency anemia.
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.
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.
