Open the vial with the preparation and insert the dropper. Squeezing the dropper, carefully spread the preparation in drops on a small piece of the scalp – preferably in the place of the parting made for this purpose. After applying the preparation, gently “roll” the preparation into the scalp. Repeat the operation on the next fragment until the entire scalp is covered with the preparation. Half of the vial can be used for one treatment, the rest can be stored in the refrigerator and applied during the next treatment. Use once a week.
