Chemical Hair Relaxer

I tried to relax anticurl Rusk Radical, which made my wavy curly hair, exactly as I wanted, for three days. He said he wud work for 3 weeks at least. I am looking for a chemical relaxer will make my wavy hair curly for a longg time (one month to 2 months). If anyone knows any of the products I'm looking for, please tell me. Thank you very much.

There is not, you could burn your skin, or worse, if you do it yourself you must go to a hairdresser.
