Rated 5 out of 5 by from 10/10 After using the shampoo and conditioner. My hair was super soft but a bit tangled at the ends from being so soft. I put this in after it air drying so it was semi damp and then brushed my hair and it's amazing and I will definitely be using this again

Rated 5 out of 5 by from Amazing! I was so excited to try the New Extreme Lengths line! I was NOT disappointed. My highlighted hair felt rejuvenated from the Biotin and soy protein after just one use. Love how it smells! My long haired clients are going to love it!
