Hi, i have really bad dandruff prob. I try every shampoo and even xpensive also cant reduce dandruff. Then my friend said use antisaptic dettol 1 or 2 cup for short hair or more if long and thick hair for 1 time showerig only in 1 day. Then a next day going shower, use normal dettol soap (green). N reminder, dandruff will fall like crazy for a first few day. Then it will be less dandruff after. And i try, it does work. But the thing is, is it ok to use dettol everytime to shampoo hair?. I have no problem so far.
