Who can use this mask and how long should a course last? — Shungit+Kremniy Mask-Active against hair loss, 180 ml

Both men and women can use this mask. The product information describes it as a good fit when you notice seasonal shedding, stress-related hair loss, or weak and lifeless lengths after colouring and frequent heat styling. Because it is a scalp treatment rather than a heavy hair mask, it can be added to nearly any wash routine without interfering with your usual shampoo or conditioner.

There is no fixed rule for how long you should use it, but the product information gives a practical guideline: a course of 4–6 weeks followed by a pause. A simple way to follow this is to apply the mask once a week for a month to six weeks, then stop for a few weeks and see how your scalp and hair respond. This makes it easier to judge whether the product works for you before you continue.

For easiest integration, use it alongside a mild shampoo and a conditioner aimed at the lengths. The mask is not a replacement for cleaning or conditioning — it is an active step for the scalp and roots. If you have an oily scalp, keep the product on the roots and rinse thoroughly to avoid a heavy residue. If your scalp is dry or sensitive, start with a smaller amount, keep the contact time short and do a patch test first.

If you are already using a medicated scalp treatment, prescription lotion or other active cosmetic, ask a pharmacist or doctor before combining it with this mask. Stop using the mask if any irritation, redness or discomfort develops, and avoid contact with the eyes. During pregnancy, breastfeeding or with chronic scalp conditions, consult a specialist before starting a new active cosmetic.
