How to improve hair health?

[image] my hair on pic, has anyone have similar type? If so which products do you use to keep it healthy? Or any other suggestion how to improve it.
So far I am using shampoo and condicioner with caffein and leave in condicioner from Czech brand Bione which is without parabenes, and sulfates. Then from time to time coconut oil. And always airdry it. 1-2x per week but it is still not that healthy how I wish. Dealing with bad split ends and knots. Any help and advice is welcomed.

Check the ingredients on shampoos you need sodium lauryl sulphate or similar to clean hair.Conditioner should contain Quaternary ammonium or a derivative to keep hair separated.You dont want hair in your brush as if indicates your hair is breaking.
Dont go above 200 degrees if you use straighteners it causes damage.Never bleach hair.Have split ends regularly trimmed off.
