I did not have a favorable BKT experience.
I have relaxed hair, not bone straight relaxed, but relaxed none the less. I was going for stronger, silky, shiny, wash and dry hair that looked as if it had been flatirioned, without having to flatiron it. These are the results that relaxed heads should get from this treatment.
I did the treatment myself back in July. I used Softliss, which is supposed to be a formaldehyde free treatment that you can rinse out an hour after using.
I used as directed, Clarified, blowdried, applied the treatment, blowdried again, then flatrioned on 450 degrees in small sections. (Mistake #1: My hair wouldn't be able to handle that without the treatment, so I shouldn't have took the risk with the treatment)
Most people have silky, shiny swanging hair at this point, but I did not, and I started to worry, but I just thought after I washed it out, that's when I would see the results. My hair felt dry, stiff and coated. Basically I had locked a seal over bone dry hair. (Not good)
Once I rinsed out the treatment, applied the mask, I wet wrapped my hair, tied it down and went to sleep. I woke up the next morning, thinking I was going to see silky shiny hair that looked as if it were flat ironed.....WRONG.
My ends were FRIED. When I say they were fried, they were burnt crispy and going every which way about 3 inches up. I tried to take pics but for some reason my cam was not functioning properly.
My hair would not accept any DC's, it was so tangly and hard when wet, and it was breaking and shedding all over the place. Small pieces, long pieces, my hair was dropping out left and right, much more than before. It was a nightmare to detangle when wet, even with conditoner. I had a friend of mine do my hair because I was so frustrated, she was like OMG your hair feels gross, It was a MESS. I thought I would have to end my journey and start over.
I immediately started using shampoos and conditoners that contained Sodium Chloride to try to strip the treatment off my hair. I was adding salt to my DC's, using clarifying shampoo, anything. Nothing was working anymore. The only thing that made it feel a little better was the Joico K Pak 4 step treatment. I almost lost hope and I really didn't care anymore I was convinced that I would have to cut off all my hair, so I had my friend cut off about 3-4 inches of the fried ends taking me from the top of SL back to the top of NL.
Pics of my hair right after the BKT before I washed it out back in July. My hair is now the length of my AVI/SIGGY. I dyed it black to camoflauge some of the damage. My hair was doing well even with the highlights.
Then about a month after, I decided to do a touch up, I was only 6 weeks post but I had nothing to lose, I had a lot of NG for the most part so I went for it. Thankfully my hair returned back to normal and started accepting moisture and protien again and it is doing well now, but I learned my lesson.
There's no miracle in a bottle, and results may vary. If your hair can't take heat without the treatment, it may not be able to take it with the treatment. If it ain't broke, don't fix it, and stick to the plan of growing my hair the "hard" way. I really feel like I doged a bullet. I still have short pieces in my crown from the breakage, but overall i'm happy with my hair now.
