Worth Every Penny

I'm a geezer with dry, curly, thin gray hair. Of the endless products I've subjected my head to, this one actually makes a noticeable difference. Because my hair is so thin and short, I only use two pumps once or twice a week. It smooths my hair, controls frizz, adds shine. Two thumbs up!

a must need for bleach blondes

this is unfortunately absolutely worth the price tag. i am a platinum blonde and this is the only product that truly saved my hair.
