Is Dry Shampoo Bad for Your Hair?

Chi Haircare's Cynthia Diersen says that anything used in excess can be harmful to hair. However, it's totally fine to use dry shampoo occasionally between washes. The trouble comes with overuse, says Michelle Blaisure, a certified trichologist with Bosley Professional Strength. If dry shampoo is used too frequently and the product residue isn't removed with wet shampoo, it can result in scalp and hair problems.

The residue from dry shampoo, styling products and pollution can trap bacteria, which can cause scalp irritation, hair follicle inflammation, dermatitis and hair loss, especially for those of us with fine hair or sensitive scalps. To prevent problems, Blaisure suggests using a product that doesn't leave behind a lot of residue, like Bosley Professional Strength Bos-Volumize Bamboom Volumizing & Cleansing Powder, $24.99. It uses organic bamboo charcoal and tapioca starch to absorb grease and impurities.

Just like over-cleansing the skin, using too much dry shampoo can actually result in more oil production, says Alyssia Dotson of Alterna. Excessive oil combined with hair follicles not being able to breathe can lead to a very unhealthy environment for hair to grow. Not only that, but dry shampoo buildup can dull hair's luster, says Dr. Anna Guanche, board-certified dermatologist and celebrity beauty expert.
