This is my first ever proper review. I had to write about these hair products as they have had an astonishing effect on my hair. I bought the shampoo to try since it had liquid keratin and protein in it. I love keratin products and i have been told my hair lacked protein once. I had an analysis done by an award winning stylist in New Zealand where she tested a few strands of my broken hair from the ends. It was so dry and brittle and was lacking volume. It was limp and lifeless. However, she applied an amazing protein shampoo and after one wash it was instantly full of volume and felt much stronger. After that i committed to using protein shampoo permanently.
