Review (4/5): This is by far the best permanent solution I have ever used
I have been getting perms once or twice a year for the last 30 years. This is by far the best permanent solution I have ever used. I have been using it now for the last 10 years or so. This does not damage my thin/fine brown hair, the curl lasts 6 to 9 months and does not stink from day one. My husband even said it almost smelled good the first time I used it!
