relaxers

so I am a cosmetologist and I have a client that has been getting sodium hydroxide relaxers from me for about a year, she has not had one in about 5 months, her natural wave has come back out and she has 4 inches of kinky newgrowth. She would like a soft curl permanent and I know thats not a good idea with thew hydroxide, but I found a thio-free perm. I have sugggested a texturizer but she would rather have curls, not just relaxing her natural poofiness. Does anyone have any suggestions or products that would be right for her??????
