After spending MONTHS buying and trying any and every hair system I could find...My stylist recommended In Common. Based on her excitement i did, and it's hands down the best system I've found. It is the lightest most nourishing stuff I've found in forever and my hair is soft and healthy and not frizzy! and to be honest it lasts WAY longer than other brands I've used. the foam is endless! So while it seems pricey, i'm purchasing less frequently than before..WIN! I can't wait to see what else they come up with!
