When I first got mine this summer I hated it. the teeth broke my hair off and i put it up for sale. then when I could not get my investment back, I decided to make it work. I made some ballsy changes in my regimen and now I ABSLUTELY LOVE IT. I don't use the teeth, but the steam feature is awesome.
the reason it didn;t work for me before is that despite hours of dc'ing and conditioning, my hair was POROUS. Now that I have introduced more protein, my hair is on point.
I use as final press after my pressing comb.
