I have naturally wavy frizzy hair with some parts even curly and whenever I use heat protectant before straightening it goes all poofy and not as slick as I want it to be, it almost looks like I’m wearing a wig since my baby hairs are the curliest part. Is there anything I can do to fix this or do I just not use heat protectant like I usually do?
