Im about 70 % natural now so i can answer this lol, for me its the flat iron, trying to blow dry my hair is one big catastrophe of rough dry HUGE frizzy hair,, flat ironing is it.. but getting my hair blown out at the salon works too only i stopped that becuz its way too damaging,, its a stuff sharp brush RIPPING thru wet hair with heat, at least a flat iron has a smooth texture, its been almost a year since i stopped those weekly blowouts and i have a lot of hair to show for it, i say blowouts are too rough, permed or natural
