Gliss is a good brand! I mean it's made by Schwarzkopf which is also a professional brand! I dont know if anyone else is like me! If u like a brand u try every range under the same brand name! I've used Gliss Shea cashmere, coconut n Marrakesh oil,total repair and even the colour protecting range ! Was happy with all! Naturally when this was launched i had to buy it! With keratin to repair n strengthen my coloured highlighted Brazilian blow waved and ghd'd several tyms weekly this seemed like a great idea! Not! My hair became v stiff n hard! Hairdressers say keratin does that to build protein into your hair! I passed this on to my mum halfway through: she likes it! I wash my hair every second day and to me healthy hair is shimmering soft vibrant! This range did not suit me at all
