What is this birch tar hair mask, and when do people choose it? — NK hair mask Tar 300 ml

This mask belongs to a classic line of natural haircare products built around birch tar — a dark, aromatic ingredient traditionally obtained by dry distillation of birch bark. In Baltic and Slavic folk practice, birch tar was used when people wanted a stronger cleansing effect than a regular shampoo or mask could give. The mask is designed for the scalp and the length of the hair. Birch tar naturally contains phenols and resins, which give it a noticeable smoky scent and a calming, slightly tingling sensation on the skin.

People typically choose a tar product like this when the scalp feels oily, flaky, or itchy; when hair looks heavy at the roots; or when visible flakes appear after a stressful period or seasonal change. The mask format is different from a shampoo: it stays on the skin longer, so the active ingredient has more contact time. In practice, tar-based products are usually applied once or twice a week, not at every wash.

The formula is generally appreciated for helping to reduce the feeling of an oily, congested scalp; softening flakes so they rinse out more easily; leaving the roots feeling lighter and the hair fresher between washes; and fitting into a simple traditional haircare routine alongside neutral shampoos. It is a cosmetic product, not a medicine. If a scalp condition persists, consult a dermatologist.
