I have high porosity hair and got a cut about 3 months ago. I haven't ever had heat damage that I know of or a stylist has told me. and I'm not CG. Just doesn't work for me.
When I say fizzle i mean that the root of the curl is a little tube of hair and then the ends kind of become a single clump of hair that still twirls but it just is like....a collapsed curl lol
