How many times does your hairstylist remind you to get your ends trimmed? I know mine tells me all the time, but that can be hard when a girl’s trying to grow out her hair. There are several reasons we get dry, split ends. It’s mainly due to heat damage from your straightening iron or blow dryer and chemical damage from dyeing, but the environment can also play a role. Last week, I met Rod Horton, a Mizani Stylist who told me about another reason our ends become ravaged.
