Review (5/5): Gentle scrub
I like using a shampoo brush, they really help the shampoo work to its fullest when I'm cleaning my hair. The nubs are gentle, but they get down to your scalp even through thick hair. There are holes in the bottom of the brush so you might want to remove the part with the bristles and let that dry out to keep the mold out. There are a bunch of brushes in this pack so if it gets bad you could easily replace it. These are great as a part of a spa gift or for yourself.
