My scalp is oily, but my hair is dry. I tend to get a really bad buildup of oily sebum on my scalp that is hard to get off. I tried to combat my scalp issues by buying increasingly stronger shampoos, but they only tended to strip my hair dry and my scalp was still oily. I was looking for a solution on Amazon and I found the Scalpmaster Scalp Brush. I have been using it since February 2016 and it has been a Godsend. I apply my shampoo to my scalp then use the brush to scrub the shampoo into my scalp. Then I use the brush again when I rinse the shampoo off my scalp – scrubbing my scalp while using the power of the water spray. This brush keeps my scalp clean and removes all of the buildup without irritating my scalp. It is also pretty durable because I have had the same brush for a year and it is still in good condition.
