Brush through your hair in the morning and night. Massage your scalp also. Massaging the scalp will basically wake your roots.
.Make sure you are getting lots of vitamins too
Do you have dead roots? Go to the hair saloon and get a trim. To prevent dead roots, don't straighten your hair, dye it, or anything damage like that. :)
Patience also helps too! I have heard if you that braiding your hair makes hair grow faster and longer... Over the night or early in the morning to night. But, if your hair is soft and healthy leave them in from the morning thought the night. Then, fix them in the morning and wear them tell bedtime. Take them out and shower! :)
My hair grows really fast. I just got a hair cut this month and now my hair is so long that its up to my nose now. I'll say don't brush your hair, use conditioner, don't use too much shampoo cause its going to dry out your scalp and the hair will stop growing. That's all I do to my hair so I'll say give it a try.
