Review (4/5): Works as anticipated
I use my normal shampoo then rinse, lately I have been doing a double wash and decided to use the aerator during my second shampoo. The lather gets much fuller the second time around after clearing up the daily pollution and dirt, it is prime time for aeration and extra scalp cleanse. It is way better than just using your hands as it gently but firmly scrubs away dead skin and oil without damage your hands can do when you have a rogue nail or dry hands. Works as described, make sure to use good batteries for the best results as the ordinary batteries worked fine but with lithium it was definitely stronger!
