True medicine is not fixing what wrong but preventing it from happening
with hair , scalp or any medical condition in general We need to ask why , not how. first is to figure out the issue , why my scalp is dry? why my hair is dry ?why I have dandruff ?
you will be able to treat effectively once you realize whats wrong
are you using the right hair cleansers ?
maybe the shampoo you are using is too harsh on your scalp or hair?
maybe the silicones in the products causing it?
maybe your skin is sensitive to perfumes?
many reasons can cause it but the solution is there in most cases .
