Apply one ampoule per day to dry and clean scalp, covering the entire surface. Do not spread the product along the hair shafts. Massage gently for a few minutes. For opening and using the ampoule, follow the instructions below:

Remove the special hard plastic ampoule breaker from the packaging slot. Attach the breaker to the ampoule by simply placing it over the neck of the ampoule. Hold the breaker between your index finger and thumb and break the top part of the ampoule by pressing lightly and steadily. Remove the special soft applicator nozzle with the cap from the packaging slot. Attach the soft nozzle to the neck of the opened ampoule and remove the cap from the nozzle. Apply the preparation to dry and clean scalp, line by line, ensuring it does not come into contact with the face. Massage gently to help the absorption of the preparation.
