I've been doing this for a while now. But my method is kind of different from a lot of peoples. So I wash my hair once a month for starters. And on the first day after the wash, I let it air dry for a bit, then blow it dry on cool. Then I put it up in a pony tail. I braid the ends of the pony tail in a semi loose braid. I then proceed to tuck the braid under and bun my hair. I NEVER undo that braid. The only thing I do is at the end of each week, I undo the bun and pony tail I made (so keep in mind my hair is still in that braided shape) and repackage the pony tail together. And tuck the braid under once more. And bun again. I don't comb my hair for a MONTH. The bun still looks fresh everyday. I rap the bun itself with a scarf every night, then I put a bonnet on top of it. In the morning I just slick down the edges and go. Quite simple. Works for me. If you are prone to tangles and matting. Then it may not be your type of thing. But I retain allllll of my growth this way. Only problem is my boyfriend is starting to complain about my hair being in a bun all the time. But whatever. He can wait til March when I decide to be a little bit freer with my hair. For now. I want to retain ALL of my growth.
