I used to buy keratin complex but las time it didn't work on my client. I think they change the formula. Now I am watching this video and this one says ,hair clean and dry, means not clarifying shampoo 🤔. Now this they rinse out mmmm after finish that us new.
I had the same experience. I'm very disappointed. If you notice the new bottle says Keratin Complex " Natural" Smoothing Treatment. I think they removed the formaldehyde. Product did not work for me either
