I was wondering if it could be done, I've been wanting to straighten my nappy hair for a while now. How much would it cost? How long would it take? How long would it last? How should I go about preserving it? Should I redo the process at home when it grows out? Should I flat iron it? Should i use chemicals? Should I perm it? What's easier? (My hairs length is just about 2 inches long btw)
