Hello
I used Rusk anticurl for about 5 years. It is a Thio relaxer, so once you begin to use it, there is no turning back...i.e. no OTC relaxers for you. If you do, you will lose all of your hair. With that being said, I loved it. I have 4A hair, and the type 3 worked perfectly. In addition, I can't remember ever having a burned scalp during the process. In fact, my hairdresser would have to constantly ask me and check on me because I would never complain of a burning scalp. Now, it can be expensive and not many black beauticians know how to use it because it is considered a "white" product. Rusk has a website to find out who in your area actually uses the product. What I did was find beauticians in my area who were on the list and ask them whether they did black hair and whether or not they ever used Rusk with black hair. I am going natural now, so I no longer use it of course, but if I did ever decide to go back to chemical straightening, I would use Rusk all over again.
