Dandruff anyone? or just a dry, itchy scalp that builds quickly? This shampoo is formulated to exfoliate (rub off) that dry skin right down to the clean scalp that you really want. It is combined with plant extracts to nourish your scalp and hair and the exfoliating agent is finely ground walnut shells. I’ve used this product and it works. It is recommended that you massage your scalp for 3 minutes after applying the shampoo. I found I need to set a timer for 3 minutes or I’m ready to quit after just a minute. Do take the time. It rinses off beautifully and leaves a clean scalp and shiny hair. I’ve even successfully used this shampoo on legs and arms when I’ve had dry skin there.
