Having used up another variation of Watsons Treatment Wax before, I can say they are good value as you get 500ml worth of mask which lasts a very long time especially if you have short hair. This is quite a thick concentrated hair mask which I leave on for a few minutes for maximum effect.
It is more effective than most conditioners, really leaves my hair feeling much softer. By the 3rd day after my last shampoo, my hair begins to feel terribly dry. I need a hair mask like this to restore softness to my hair. A tub this big lasts more than 3 months even when used regularly.
