This store is your one stop shopping location for all your beauty needs. It has shampoo, conditioners, styling products, colorings, etc... And I think some of the locations even have stylists and manicurist! These stores tend to be a pretty good size and they seem to be growing in numbers.
You should check this place out. The staff seems knowlegable and there are good deals to be had on their special products (like shampoo and conditioner packages. They have tons of brand name items here and always seem to have a very good stock of the items on hand. And they keep up with the times with the newest products too. There are many locations in the Bay Area so just look them up, there is bound to be one near you.
