During flare-ups (chronic xerosis, atopic dermatitis, severe cases of psoriatic lesions), apply the product daily in the morning and at bedtime onto the affected areas, and especially the hair-bearing areas of the body and wet or dry scalp, using a comb to part your hair. Spray the product onto each parting three times by pressing the atomizer button. Then rub it gently into the scalp. Do not rinse. Use the product preventively a few times a week at bedtime.
