Awful hair brush. I tried this in my hair (straight Caucasian hair) as well as in my daughter's hair (wavy bi-racial Caucasian and black hair). It was very harsh and rough for both of us ripping out hair rather than detangling it. This was even after using my daughter's "refresh" spray in her hair. I will not be using this hairbrush at all.
the bristles are very very fine and flimsy which I thought would be an issue but the brush is surprisingly amazing at detangling both wet and dry hair! I have wavy blonde hair and it tangles easily for context.
I was concerned that my former plastic brush/comb was tearing out my hair, so i switched to this. Smoothly detangled and did not feel aggressive. My hair dresser said that it's okay to use it in the shower, so i did, and just dried it on its side once done, as the bed of brush was designed with a tiny hole in it, so water does seep into it. Unfortunately, after about 5 months the brush started to break down. The bristles became softer and more flexible, so it wasn't doing its basic job of brushing through my hair, and i have very thin hair, so it stopped being capable of even doing that. Also, after about 5 months i noticed that a mildew smell started coming from the brush. Even though i made sure to place brush on its side to dry after using it in the shower, to ensure it was properly drained, it still managed to accumulate water inside the brush, clearly, so that makes it not practical as a "wet" brush. I always washed the brush with shampoo weekly as well, so it's not like i wasn't cleaning it. It's a shame because i really like that this brush is a bit more eco-friendly than others. Hopefully this company can build a more durable wet/dry brush in the future.
