I did a Curlformer set with the extra wide today to stretch my hair. Overall, I was disappointed with the whole experience for two reasons. One, I used Lottabody today for my set for the first time, and I feel like it may have been a waste of money. My hair looked the same as when I just do Oyin Hair Dew. I did a 3:1 ratio this time, so I'm going to try a 2:1 ratio next time.
Second, I've tried all three Curlformer sizes and I think I like wide the best. The extra wide is better for stretching, but it was harder for me to put in. The mouth kept bending, which made it hard to pull the hook through. It also made it hard for me to get close to the root. Also, I usually wear hair curly when I first do the curlformer set, and then use the stretched out hair for other styles. I think my hair is too short to use these for a curly style, so I looked funny.
I don't have pictures because I feel asleep on my hair on the couch and it now looks a mess. I'll probably use these again when I just want a stretched style, so I can work on my technique with these. I'll try to take a picture then.
