Don't use too many chemical services in your hair. Be especially aware of permanent colour, that stuff is evil especially if you already have your hair processed (relaxed etc).
Permanent colour with ammonia & peroxide = Dryness & Breakage
Keep your hair moisturised
Take vitamins
Eat healthy
Don't overuse heat, if you do, protect your hair.
