You shouldn't have to, but if it is human hair, you can do anything to it you'd do to your own hair.
Only If It Is Human Hair.
Use relaxer, or get a weave.
I tells you in the instructions for whatever relaxer you have, but I would say everybody's hair is different. I have thick strong hair, and I put in a regular strength relaxer every 2 months.
Yes. That's why you have to touch up the relaxer, ha.
yes
Yes.
Yes, you absolutely can put grease in your hair if it has a relaxer in it.My oppinion is you shouldn't put a lot of grease in your hair at all. If you do this..your hair might get way to greasy and look very unhealthy. You should ask a professional about it.
you can put in a weave
They put in weave, or put in gel or brush it
Straighten it Straighten it
You should first see a hair dresser who can put the weave in properly, then you wont have that problem
