Review (5/5): For the price and overall result - you can't beat it!
I will give this keratin treatment five stars. It arrived very promptly and no issues with bottle leakage. I started by washing my hair with Dawn dish detergent (as noted by another seller who provided feedback), did NOT condition and blew it completely dry. I then separated my hair into four sections and added the solution to each section separately while combing through with a fine tooth comb. I did my best to get as close to the roots as possible and saturate all strands without 'over saturating'. I chose to leave the solution in my hair and dry it immediately following the application. I dried it straight on the highest heat setting. Once this step was completed I flat ironed while going over sections 3-4 times. I did this step on a Wednesday evening and washed it out the following Saturday. It did feel a bit heavy, needed hot iron touch up each day and smelled a bit like pickles. But I found the cons totally worth it once I washed and styled my hair on Saturday. It looks and feels healthy, is FAR less susceptible to frizz and is holding up quite nicely. This is huge given that I have curly - frizzy hair AND happen to live in humid Florida. For the price and overall result - you can't beat it!
