Review (4/5): This product works!
I was hesitant, to say the least , about doing keratin myself. i watched a ton of videos and how-tos and decided on keratin research brand because of reviews both bad and good. i used the product as directed, and i used a mask during the drying process- totally smells-i actually didnt wash my hair for two days afterwards even thought they i could do it right away. IT WORKS! my hair is soft and shiny, and frizz free. it took some of the wave away but thats ok with me. its a little hard to do the back of your head with a flat iron, but i was slow and steady... its was $65 and a Brazilian keratin is at least $300 near me. so if i have to do it again in three months i'm good! try it!!!
