I use this more as a smoothing gel than for straightening. My hair is thick and curly and will typically only straighten with a flat iron. Blowing it out takes minimum 45 minutes, and it will be super frizzy afterwards. Nowadays I just leave it curly and use various things to keep the frizz down. I'm not even sure if they sell this anymore. I've literally taken over 5 years to go through it. It smells incredible. Only complaint is that it's one more plastic thing.
