I am an African American female. I say this first because I know personally when looking for products, I always ask myself "Will this work on African American hair?" To top it off, I am also transitioning (For those of you who don't know what that is, I'm letting my relaxed hair grow out) I have 4b hair. This is to just give you an idea of where I'm coming from with this review. On with the review: I LOVE THEM! The first time installing them was a pain in my butt, but I got used to it and its a breeze now. The first time I did it, I put them in on wet hair and let my hair dry. The curls were extremely defined. To curly for me, almost like Shirley Temple. The second time I put them in, I did it on blow dried hair and only left them in for 2 hours. If you've ever gotten a roller set, that's what my hair looked like but with a little extra curl and so full and bouncy. I fell in love with this way of doing it and just finger rolled my curls at night. The third time I tried it, i did it on air dried hair. It came out the same as blow dried hair. This is my go to way of doing it and I absolutely love it. My favorite part about them is it is good a blending my two textures (the new growth and the relaxed ends) The only thing is, I wish they were a little more comfortable. I start the curlformer right at the root which is a little tight but that is my only option since I want to blend my hair. If you hair is all one texture, you def don't have to start at the root and it'll be a little more comfortable for you. Last thing...what I really don't like it that at some point, your hair will grow out of the curlfomers :/ Women with straight hair can put them on their ends and be fine but since my hair is puffy, I don't want puffy roots and curly ends lol Oh and I bought 2 sets to get more defined curls, my hair is extremely thick.
