I’m going to do this myself and save $$$. The hardest part is 400 degree flat ironing 10 times each section. This will burn your hands so I bought heat gloves and a Tension Comb recommended by BKT companies. The video below is the best instructional video for BKT.

I'm going to give myself a professional BKT that lasts for 3 months for under 25 bucks!
Don't buy LK. It's a terrible product.
Where did you purchase your bkt treatment? I actually used the LK on my hair today and I can definately say I can see a difference. So like all things it works for some and not others. The only con I see is that it doesnt last as long as the others.
