Yes. This shampoo is for people whose scalp tends to become oily quickly, whether or not visible flakes are present. Birch tar oil helps loosen the greasy film and built-up dead skin cells on the scalp, which is useful when roots lose freshness faster than the rest of the hair. People who use styling products regularly or wear hats often may also find this type of wash helpful, because those habits can leave residue that makes hair look flat or oily at the roots.
In a routine, use it as a scalp-focused shampoo rather than an all-over polish. Massage a small amount into the roots, let it foam, and rinse. If the lengths are fine, you do not need to work the shampoo through them. Follow with conditioner on the ends, or skip it entirely if your hair does not need extra moisture. Many people pair this with a more moisturizing mask on the ends when they want both a clean scalp and softer hair.
Because it cleanses thoroughly, the result is often a scalp that looks and feels fresher between washes. This is a cosmetic product for cleansing and care, not a treatment for any skin condition. If the scalp becomes painful, blistered, or noticeably more irritated, stop using the product and consult a pharmacist or skin specialist. For an oily-root pattern, consistency matters more than any single wash: regular cleansing keeps residue from accumulating, which is why visible flakes may become less prominent over time.
