Not effective rather keeps the hair frizzy and dry. Even when using with Thuja shampoo doesn't make a difference as dryness still prevails. Seems for a while to work a little on hair but zero effect on scalp, despite of using both thuja shampoo and amla conditioner together. Only good thing which company claims is zero side effect as is homeopathic but it seems that it even lacks essential components to treat Dandruff and Frizzy hair.
