Thank you all... will try and let me post about about that...

Message your hair with olive oil atleast once a week.
don't brush your hait when it is wet....let it dry first because brushing in wet hair leads to split ends.
Eat healthy food that supports the growth of hair
-hope this helped :)

Use a hydrating shampoo and conditioner, leave-in conditioner and perhaps a serum (except in fine hair). Make sure to trim regularly (every 4-6wks). Use a mask once a week. Brush only when dry and comb out when wet. Use a heat protectant before any thermal tools are used.

You keep your hair long, by taking good care of it. Remember, longer hair is older, more fragile hair. Don't wash your hair everyday, maybe every other day. If you comb your hair after washing it, use a wide toothed comb. Look for a shampoo that is sulfate-free. Sulfates are rough on the hair and can cause breakage. Get regular trims. I know that SEEMS counterintuitive, however split ends will just continue to break your hair shaft. You can ask for a "dusting" which is the trim of the very far ends.
