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

Great result but very expensive
I was a bit sceptical before buying because leave-in masks aren’t usually part of my routine and I was worried about a greasy finish on my fine hair. After checking the proper application, I realised a very small amount is enough. I could already see the benefits after the first use and I’m really happy with the results. The only downside is the price, It is very high for the quantity
