any info. on life after a vigorol ???

I used a vigorol liquid relaxer. Now that I know it contains a chemical called Ammonium Thioglycolate, not the same as your types of chemicals found in our usual perms,no- lye or lye. I was wearing my hair short and wash & wear, now I wanted to go back to straight with those lye and no-lye perms. I have been told "dont do it, because I risk hair damage, due to the diffrent chemicals in the two types of relaxers" I have been told by my own stylist " I can go to a regular relaxer now, because when I did do the vigorol, it did not damage my hair " and last I recieved some infor. that if I used a product called " Pro- Design " mixed with my relaxer, which is supose to stop any damage, by treating with protiens and the things our hair needs . I can go to the traditional relaxers safely.However I can`t find that stuff in stores. Someone , anyone if you have any knowledge on the subject please share with me. Otherwise, I have been told I will just have to let my hair grow out and start fresh, after cutting where the vigorol was at off.

Help !!!!!!!

I had a vigorol as a child so I don`t know if it was the same kind as they are selling now but I now have a relaxer in my hair but I put it in many years after the fact so the vigoral may have grown out by then. I`m sorry if that didn`t help but I didn`t experience any breakage.
