Many folks would protective styling which is great but creating a awesome regime will help with growth. You have to learn your hair first. Low manipulation styles like twist out or braid outs. I do flat twist n curls and they last 5 to 6 days. Also trimming (yep I said it! But you will have if the ends are raggedy.)

Finger comb. Don't use brushes or combs. Only detangle on wet conditioned hair. Do NOT trim unless split ends. If it ain't broke why fix it. Trimming for growth is a myth unless it is because your ends are split or damaged. I dont like protective styles but I consider my 2 times per week Cowash and refreshing with water and some oil using a spray bottle on no Cowash days a form of protective style. When I refresh I don't really you hair. I only saturate hair and shake hair to loosen curls. I also prepoo with evco mixed with a few drops (2 to 4) essential rosemary oil.
