Wear a Wig
Wear a half or full wig until your hair grows out. You will still need to take care of your natural hair while you are wearing the wig. You may want to braid or twist your natural hair while you are wearing the wig.
Have someone put braids into your hair. Use human hair when getting your hair braided. No one will be able to see the bad hairstyle that you had.
Get kinky twists with extensions put into your hair. You should have the twists done every two months to keep your hair looking neat.
Cut it off
You can always start all over from the beginning again. That is if you are not scared.
