I've been using both tools for about a week now, and I'm impressed! The shampoo brush really helps make my scalp feel clean. I feel like my hair is much more voluminus since using it and just feels over all cleaner than it had before. I'm not sure of the cellulite messaged is getting rid of my cellulite, but it definitely feels great to use. The bristles on both tools are made of a soft and flexible, but very sturdy silicone. I love them!
