Used this for around a year, use once a month in alteration with ny briogeo mask. It easies breakage and makes hair a lot more manageable.

I use this along with the leave in treatment definitely worth it 

I am using this semi regularly and haven't had time to access if it works. Smells nice though

Mildly conditioning with great results. Redken's Acidic Bonding Concentrate Pre-Treatment leaves my hair feeling soft and manageable, I have noticed significant improvement in terms of strengthening and repairing damaged strands. It's a decent option for maintaining hair health

Definitely see a bit of a difference using this!! Only been a couple of times but hopefully will see better results with time
