I use this shampoo by myself I never satisfied by any one shampoo I try lots of shampoo some of them was gun in starting but after sometime they didn’t suit me at all I can say that tresemme suits me. Its all depends on type of hairs I have curly hairs according me its gud for curly hairs if ur hair ruff it’s going to help u alot I saw lots of people mix shampoo with water to increase the quantity so plz stop doing that then whatever shampoo ur using its not going to help ur hair at all according to me tresemme is really gud shampoo try to it with the conditioner
