The $20 pH-Balancing Shampoo a Dermatologist Loves for Keeping Her Graying Hair Healthy and Shiny

Shirley Chi, MD—a 46-year-old dermatologist who is starting to gray—wants to keep her hair as healthy as possible while also makings sure it looks its best. One of the ways she does that is by using a color-safe, pH-balancing shampoo that gently cleanses her hair while leaving it strong and sleek.

"In particular, I like the Zerran Botanum shampoo because it's formulated for chemically treated hair and it has the right pH of 3.5 to 4.5 to keep your hair follicles healthy and shiny," says Dr. Chi.

The shampoo's pH is acidic, which is a good thing for your strands. When your hair's pH is basic (aka greater than 7),, it can increase its negative electrical charge, which in turn can increase the friction between fibers. According to Whitney Bowe, MD, a board-certified dermatologist in New York, this increased friction "can actually lead to cuticle damage and fiber breakage, which translates into dull, damaged hair. Optimizing the pH of our hair-care products can, therefore, also benefit the overall health of our hair."
