If you're talking about the blow drying serum then yea i've used it for a long time but i used it for pressing my hair i think its a heavier serum and that's why i felt it was ideal for pressing because it actually prevented my hair from reverting. Now that i've relaxed/texlaxed i use frizz- ease the one with thermal protection its a lot lighter although i hate the smell but its the closest to their discontinued texture correcting one which is the best serum i've ever used it actually corrected my texture as i said its heavy so if u use it make sure to use very little if you don't want your hair to be weighted down...
