Also, would it look weird/dumb if I only have a few on the bottom of my head?
Basically, all you have to do is choose a starting method (I suggest backcombing, crochet hooking, twist-and-rip, or any combination thereof for your hair type), section off some squares at the nape of your neck, then start your locks! Everything else from there is simple.
Aftercare does not require much and will not affect how you wash the rest of your unlocked hair.
This won’t look silly at all; we get questions about it all the time! It is far more common than you think! We have a tag packed full of starting tips, sectioning tips, photos, and other Q&As that I suggest you read over before starting. It should answer any question you have!
If questions still remain after reading the tag, please let us know! We would love to help.
