5.0 out of 5 stars Buy it!

Super satisfied! I have super curly frizzy hair. I used to get my hair relaxed but wanted something easier on my hair and something cheaper. 3rd pic is hair after treatment air dried and last pic is with it dried and flat ironed.
I will say the process is long but for the price and convenience it is worth it!

3.0 out of 5 stars Fumes is very strong

The containers are for one use only based on the size. The fumes that comes from the treatment is horrible so I would highly recommend that you do not use this in a closed space. But works ok as a DIY
