Experts: Dry Shampoo Could Cause Balding

PHILADELPHIA (CBS) -- This is mostly about the improper use of dry shampoo, which many women love to use. It is supposed to be sprayed on the hair and not directly on the scalp. Doctors say that when it is overused, it can cause problems.

It's the styling secret that women swear by, swapping out your daily hair wash, for dry shampoo.

It's designed to soak up oil in between washes. Your hair looks fresher without the fuss.

A picture, posted by Nicole Baxter on Facebook and shared 33,000 times, has many scratching their heads. Many dermatologists blamed dry shampoo for the bald spot that was forming on her head.

Experts say that dry shampoo can build up on the scalp. Stephanie Johnson, a licensed hair stylist says the natural oils, that need to escape your scalp, can be trapped by dry shampoo if you use it too much.

Dermatologist James Ralston says dry shampoo can plug the hair follicle and trap bacteria. "That bacteria causes inflammation in the hair follicle which leads to pimples or cysts," Ralston said.

Doctors say the other potential issue with dry shampoo is contact dermatitis. Some contain fragrances and preservatives that can cause an allergic reaction on the scalp.
