My hair is falling a victim to dandruff and flakes on my scalp.most of the time i will be scratching my scalp without finding any relief that results in a burning sensation.and on top of that the dandruff is very much visible on my head as my friends keep on pointing that they can see a large amount of white dust on my hair ,but then only i know how i escape their sarcasms over me.so my friend gave me Everclean Unscented Anti-dandruff Shampoo.is Everclean Unscented Anti-dandruff Shampoo herbal in nature and if yes what are the herbs that go in to cleansing the scalp and eradicating all the impurities from my scalp?
