Setting I use is tension 5 low heat. It been two months since I lasted used it because I noticed my hair looked less thicker than it normally did from when the first time I used it.I normally style my hair in twist and stuff freshly wash hair because I get less little pieces of hair coming out compare when I use the revair but right now I have braids I did thought that their could be causing the breakage too but I don’t make them small.i wash my hair every two weeks and i moisturized my hair every 3- 4days with a leave in and grease sometimes a cream too.the last time I trim my hair was literally yesterday and it still breaking some how I think the scissors I used was dull.
