This hair mask is amazing, it hydrates and repairs without weighting down your hair, and it's specially suitable for the hot and humid summer climate in Hong Kong, because it won't leave your hair sticky. It has a very light floral scent that makes you feel really fresh.
My only complain about this product is it's price, I've got shoulder length hair and one tube was only enough for 4 application, kind of expensive.
