is there a way i can get my 4c hair back after millions of straightings in my hair
Yes, You cut the heat damage off, all of it, you can't fix the results of the damage if the damage is still there, sorry, then you start deep conditioning and do hot oil treatments twice a week, after 2 months of doing all of those very strictly, you will see major difference and your curls will pop out and your hair will practically be thanking you. it will be hard at first but its worth it.
Cut the damaged ends
You will always grow curls! You just need to cut the heat damage off and start growing out the gorgeous curls you were intended to have!
