What does the card say about the composition of the Super Psori shampoo? — Super Psori shampoo 100 ml

According to the card, the shampoo formula contains tar, naphthalan oil, keratin and plant extracts; the pack holds 100 ml. How naphthalan oil differs from tar and why both components are needed, the card does not explain; the claims about antimicrobial and antiseptic properties and the treatment of flaking and dandruff have no confirmation.

General information (not a manufacturer's instruction): tar and naphthalan oil can irritate the skin; in case of pronounced flaking or suspected psoriasis, a doctor should be consulted.
