And! This just happens to be fan-favorite amongst the BuzzFeed writers — including myself. I have one of these shower companions, and while I don't use it every time I get sudsy, I usually run it through my hair after a few days of back-to-back dry shampooing. It really gets in there to clear up any buildup while also feeling like a nice little scalp massage.
Promising review: "I’ve suffered with dry, flaking scalp for about a year now (pretty much started when I was pregnant and hadn’t gone away). I have used tea tree oil shampoo, dandruff shampoo, coconut oil, you name it. I finally read somewhere that exfoliating the scalp might help, but I was hesitant because years ago, I had a shampoo brush and it was very rigid, the bristles were fine and close together, and it made my hair a tangled mess. Anyway, I saw this shampoo brush and it looked a lot more flexible so I thought I’d give it a try and HOLY MOLY my flakes are gone! It’s made out of a silicone-type material and the little 'bristles' are flexible but still get the job done. I can literally brush my hair with shampoo in and it doesn’t get tangled. It’s amazing. Not only do I have zero flakes now, I feel like using this does a way better job at working the shampoo in and getting your hair and scalp really clean. I have super thick hair and no matter how much shampoo I use or how long I scrub my hair, I felt like the back, underneath part of my hair would sometimes stay dirty. This brush gets all that." —Meg R
