The Best Shampoos and Products to Treat Thinning Hair, According to Dermatologists

If you have thinning hair, you’re in good company. In fact, it’s perfectly normal to lose an average of 50 to 100 hairs every day, according to the American Academy of Dermatology. Hormonal changes are one of the main reasons for hair thinning in women. It often happens when you start or discontinue oral contraceptives, postpartum (approximately four months after giving birth), and menopause, according to Francesca Fusco, MD, a dermatologist at Wexler Dermatology in New York City. Another very common cause of hair thinning or increased shedding is inflammation of the scalp. "This is commonly seen in dandruff, with the patient experiencing an itchy scalp, flaking, and irritation," Dr. Fusco explains. If these symptoms go untreated, they may lead to hair thinning.

The good news is that there are plenty of products to help restore some of the lost hair, whether they're shampoos, hair oils or over-the-counter supplements. Here are some of the most effective hair products for hair thinning or loss, according to dermatologists.
