I bought this Hydration mask a few months ago and used it roughly every other time I washed my hair after using the Hello Hydration Shampoo from the same range. I have quite long, thick and wavy hair and the mask left it feeling really soft, shiney and tangle-free. I straighten my hair regularly which can cause it to get dry and damaged but the Hydration mask definately helped to keep it moisturised and to protect the ends, it also made it a little more managable for straightening. The instructions on the tub tell you to apply the mask from root to tip, then to leave it in for a few minutes, I was a little apprehensive that putting conditioner into the roots would leave them looking greasy even after rinsing it out but this wasn't the case at all and I was definately pleased with the results.
Herbal Essences products are often on offer at Tesco and I think I bought the Mask along with the shampoo and the normal conditioner when it was on a 3 for 2 offer, making it quite reasonably priced. At the moment the mask is half price (£2.03), I will definately buy this product again in the future, am just trying to use up all the other products that I have bought whilst they have been on offer to make room in the cupboard!
