Hi Corey, glad you made a decision and started your journey. I will start off by answering your questions:
- Should you be crocheting it: NO NO NO
- What should you do about the loose hairs: let them be, it's just part of the process, whether it is backcombing or twist & rip, they loosen up first, those methods are only starters, blueprints to your dreads. Are you cool with wearing any beads on them, guy beads? This will help.
- Should you sleep with a hat on: NO NO NO, let you scalp breath man, you will sweat with football, that's enough on the scalp, don't sweat overnight too
- Can you wash them everyday: Wash them 2-3 times a week, but you sure can wet them with water every day, no problem, just don't go to sleep with them wet
Don't expect miracles with only 4 inches of hair right now. If you have Caucasian hair, it really likes to do its thing when it is 6 inches.
Backcombing is not bad, it comes after T&R and neglect, so don't worry, many people on here have started with that method, just don't re-backcomb them or you may have lasting damage. I myself started with twist & rip, not neglect. I will say that if you want dreads to mature and to last you for years, then don't crochet, it never allows them to truly mature. Even doing it once will set back the maturing process by 6 months. Your hair, your choice. Have a great football season...Peace
