My favourite product from Redken and honestly my only one is this acidic bonding concentrate pre-shampoo treatment.Is a bit pricey but I had damage hair so I needed to try it out. On damp hair apply a decent amount of product, leave it for 5 minutes and after that shampoo, conditioner and styling as usual. You wonโt believe how my hair ia: so shiny, healthy and no frizzy. This product ia amazing.i use it once a week or two. I swear worth every penny.
