I have long, thick, coarse 2C/3A curls that used to take 45-60 minuted to completely blow dry. I hadn't realized how badly I needed this dryer until I used it for the first time. Before purchasing I was super skeptical about its effectiveness on my type of hair, and obviously the price point was a little scary. It now takes me 10-15 minutes to blow-dry my hair with the diffuser, or with a round brush if I plan to straighten my hair. The diffuser distributes air and heat perfectly, and the highest setting is actually too much. I can tell I'm doing less damage to my hair with how much time it saves me on a daily basis. This blowdryer is worth every single penny!!!
