Unfortunately a must have

I was praying to God i wouldn’t like the product because of how much it costs but it really is that girl. After a course of this i feel like i have the hair of my dreams

Holy grail level for damaged hair

My hair genuinely feels stronger even after one use. I’ve tried all the trending hair products- and this is one of the two that I’ve kept as my holy grail. Take a dime size piece and add to the tips (the acidic bonding one) perrrfect duo.of your hair. Then I recommend using the redken leave in shampoo
