I don't use any hear products or brush it when wet. I use TreSemme shampoo and conditioner for dry or damaged hair every other night, but rinse it with water from the shower every night. I wear it in a messy bun almost every day and if I straighten my bangs I use TreSemme hear protectant. I drink about 8 glasses of water a day, am a 13 yr old female and have a pretty healthy diet. Also I wear my hair in a messy bun almost every day to protect it from wind and rain. So how long will it take my hair to grow that much? It's December and I want to know how much longer it will be by April. Thanks! <3

There's absolutely no way to tell you. Every persons hair grows at a different rate. It really depends on your hair, and what's normal growth for you.

Hair grows an average of one-fourth inch per month.
