This is in reply to Great Qatar ; apparently the Keratin Shampoo is in no way hazardous to the hair as this does not contain Sodium Chloride, Sodium Sulfate and some other chemicals that strips the hairs natural keratins, instead this is used as an aftercare process if someone has undergone the Keratin Treatment, which is done to eliminate Frizz and control Damaged Hair. It is always advisable to read the contents on any Shampoo and conditioner you use, before purchasing it !!! Cheers.

And to Soniya ; well said my dear, cause some people try to experiment on their own and then the end result is damaged/frizz hair.
