The emfohlene minimum application period of 10 days at the Gliss Kur Serum Deep Repair Shampoo should also be respected - only then can determine a positive result!
Day 1-3 of the application: Very pleasant texture and odor, after foaming (and leave on) are the hair but still so rough. I was disappointed!
From day 4 you realize then so slowly that the hair "smooth" to be. This suggests that the 10-day construction of keratin so slow effect shows :-) So go ahead!
From there it goes up every day with the hair structure and is exactly what the shampoo indeed reach. For me a shampoo that I will apply 3-4x as "cure" in order to give more body and substance healthier hair. But not for every day, because I just need a shampoo that leaves after washing "squeak" the hair.
The ingredients should be evaluated surprisingly positive. Apart from the so-called PEG / PEG derivatives (such as emulsifiers combine water and fat; can make the skin more permeable and pollutants in the body infiltrate) and Dimethicone (environmentally relevant) there is not much to criticize. Compared with other brands surprisingly little :-)
Therefore, for me a good occasionally to use product with only minor deductions.
