Why does full strength pre-treatment make sense? Other medicated shampoos direct you to add water, lather and wait. Taking this approach treats the hair, the unaffected scalp and problem areas equally, with perhaps more water than medication. And who wants to wait around with a head full of lather? Tarsum is different. Use Tarsum's unique applicator tip to apply Tarsum full strength, directly to affected areas of the scalp BEFORE showering. You can apply Tarsum and go about your morning or evening routine while Tarsum works full strength to help eliminate flaking, itching, redness and irritation. After a treatment of a few minutes or up to an hour, simply add water, lather, then immediately rinse. No more waiting in the shower for your shampoo to work. You have time to use your favorite conditioner, or simply spend less time in the shower. Full strength, medication and convenience - Tarsum has it all!
