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 and 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. I will also add that if you’re dealing with dry scalp (not dandruff) use a shampoo brush, don’t go long betweeen shampoos (I had to bump mine up to every other day), take a good quality fish oil, and drink LOTS of water.
