Check out a TikTok of the scalp renewal brush in action.

Promising review: "I was not expecting this brush to be so amazing. I usually use a Wet Brush, and NO MORE of that. This one doesn't pull when the Wet Brush did. Feels amazing on my scalp. Just a very refreshing brush to find. I would definitely recommend this to everybody that has a hard time brushing their hair (even kids), very soft, and the price is excellent as well. Love love love this brush. Would definitely buy again and again." — Katy Shoemaker

Price: $7.99 (typically $12; available in four colors)
