Urban Care Intense Keratin Serum Weakened My Hair and Caused Color Fading

Hoping Urban Care's Intense Keratin Hair Care Serum would help heal my dry, damaged hair and lower frizz, I opted to try it. For several months, I used the advised daily application hoping for better, healthier hair. But rather than getting better, I began to find my hair felt thinner and looked to be weakening. Concerned about the long-term consequences of the product, my natural colour even seemed to be disappearing in some places. Considering the money I spent on this serum, I am somewhat let down and worried about these sudden developments. I want Urban Care to look at possible problems with this recipe and make sure no more clients get these upsetting reactions.
