I'm a natural blonde, so I think as a rule I have very fine, delicate hair. That being said, my hair is about 7 inches past my shoulders and very thick - that's a lot of hair to detangle/brush through.
I definitely CANNOT detangle my hair with this brush after the shower, you know unless I want to rip half of all my hair out of my head. However, this brush is awesome for a blow-out. I generally only blow-dry my hair from the roots to about 5-6 inches down my hair and let the rest air dry, and this is PERFECT for that. The wideness of the brush allows for a really quick dry since a decent amount of hair can be spread apart and brushed through at a time. Plus the little quote on the back is pretty cute.
My hair is thick, & colored. Since getting it colored it gets tangled very easily, this brush is great for gently untangling and making hair smooth and manageable. A little overpriced but with a coupon or birchbox points it well worth it, if you have tough hair.
