Does blow-drying cause thinning hair?
A. Although a blow-dryer can cause damaged, brittle hair, it’s not the reason you are going bald. That being said, it’s best to limit blow-drying as much as possible to keep your hair healthy and shiny. Also, don’t overload your hair with styling products — they weigh hair down, making it appear even thinner. Towel-dry hair and then add a dollop of light mousse. Finish drying your hair quickly with a blow-dryer, on a low setting, or let it air-dry.
