I've increased the vitamins I take as well as using much less heat and protective styling. Oh, and not letting people who think they know a lot about hair do whatever they want to it.
(off topic)
I just took my braids out on Saturday b/c they were getting a little old and now my hair will be in a braidout for the week. My friend saw me and said, "What did you do to your hair? It looks nappy." Now keep in mind that her hairline is almost non-existant but she continues to wear lots of glued-in tracks and uses a lot of heat on her hair. She then proceeded to give me a lecture on how my hair doesn't look professional and that people are going to talk. I defended myself and told her that there are many girls on my campus who don't have room to talk about MY hair and what I do with it is my business. Ever since I stop letting people do whatever they wanted to on my hair, it has flourished, so yes, I can testify to that. Thanks for listening to my rant.
