Review (5/5): these are good!
I relax my hair a few times a year. I have very thick coarse hair that is also a little bit wavy, and this gets it pretty straight. The only thing I don't recommend is toleave it on too long, or your hair will break off. Unfortunately that happened to me lol, but my hair grows pretty fast so its not a big deal, just be careful since it's very strong and very effective. I'll definitely be more careful in the future and time it a little bit better. Will probably try the mild next time. But it relaxes well and the perm last a long time.
