Denman D6 Shampoo & Shower Massage Brush

If you have sensitive scalp this would be quite rough, especially in the shower. Don't see how hot water would soften the plastic bristles, since it's just plastic that has rounded bristles so it didn't feel any different but quite rough and spiky.

The brush really works into your scalp. Massaging it causing the follicle to be stimulated. Great product. I probably wouldn't use it for brushing your hair in the shower.
