This is something that you might have noticed on quite a few models, and it might be a feature on the one that you use at home and you just never use it- but you should! When you use heat, it opens up the follicle and can make it look frizzy or damaged- especially when you are using it on the highest heat setting. If you want to make sure that you have a sleek and flawless look, while also promoting shines and reducing frizz and static, give it a one over with the cool shot to lock in your look. Plus, the cool shot is perfect when you are attempting to dry off in high heat and humidity in the middle of the summer- it will feel great against a hot scalp.
