This is the best shampoo for wavy hair if you want them straight . I have wavy hair and evertime I use tresemme keratin smooth it makes my hair soft and straight. It also control the frizziness of the hair. I really love the after effect and my hair are good for 3 days.
This the amazing shampoo having a fruity smell which is just lovely and I am addicted to the smell. I have tried many shampoo but this works best to my hair. Worth the price . Little expensive but big thump up for the result . Luving it.
