Cleansing scalp scrub. When a deeper cleanse is required, the Exfoliating Foaming Scrub is the right product. Like a skincare product that does a double cleanse, this dual-action scrub transforms into a luscious lather to gently exfoliate the scalp while leaving hair beautifully clean, fresh and soothed. How to use: Apply directly to the scalp and gradually add water to create a lather. Massage into scalp and distribute to hair lengths as needed. Rinse thoroughly. Then apply your favorite JOICO conditioner or mask to the mid-lengths and ends.
