Story of my Life! Im a 3b with hair just a little bit past my shoulders and I'm trying to grow out because longer it'll be looser.
I took biotin and it seemed to work pretty well for me and now I'm taking a go at mane n tail.
If I were you what helps me is to rub my scalp everyday day softly with me finger pads and even better with oil. And hot oil treatments are amazing and they help me maintain my hair.
