Just wanted to update on this, hair is still frizz-free/minimal... 1.5 months later. Other perks: i had thin unhealthy looking hair with no shine, i now have full full looking shiny hair. I also used to shed like CRAZY... My hair is really thinning, I shed about 90% less after this BKT. I used to have terrible dandruff... I have had zero dandruff since doing this treatment and using sulfate free products. After reading on here importance of deep conditioning, i purchased liquid keritin deep conditioner by coppola. Great results! My hair is beautifully healthy!
