My hairdresser recommended this mask for my very thick, fine slightly wavy hair. Very pricey! But it smells absolutely wonderful. I have previously tried Sebastian shampoos and conditioners, didn't repurchase as the quality did not justify the price! Gave Sebastian another shot with this mask. First of all, I hate the tube! The screw-cap is stupid and annoying, I always end up squeezing out extra product and the whole tube is slippery in the shower, and I've lost so much product down the rain because of the clumsy packaging. As a hair mask, well I'm not satisfied. I don't feel like it's absorbed into my hair, it just coats the hair and is washed out.. Waste of money!(I might try sleeping with the mask, and then maybe I'll change my review)
