So I asked from my friends. A friend suggested this product here. She has hair extension and told me that one may as Never use silicone or plasticizers, otherwise loosen the hair. She explained further that this special shampoo for own hair is well suited.
So I ordered it and what can I say? That's it !!! My hair has grip that locks lure again, there are no smooth-maker there, let my hair look like after a storm. My hair has jurisdiction and can be styled well. Do not electrify. I am absolutely delighted and will now give any other shampoo or use up as hand washing.
Fabulous! Finally one without all Weichmacherkram, I absolutely can not do.
