Cosmetic world has been my go to for years (instore and now online) for quality haircare products at a reasonable price, including the full Kevin Murphy line. The Stimulate-Me Wash (shampoo) washes without stripping moisture and has a cooling/invigorating effect on your scalp. I've used this, in combination with the stimulate me conditioner, for helping combat some hair thinning (stress/hormones) with some success. Will purchase again.
