Is Preferance 9.13 Baikal safe for sensitive or damaged scalp and hair?

The formula contains ammonia, hydrogen peroxide, and resorcinol, which are common irritants, so individuals with sensitive scalps or damaged hair should perform a patch test and may experience irritation; the conditioning esters can mitigate dryness but do not eliminate the risk.

What role does resorcinol play in this hair color product?

Resorcinol acts as a coupling agent in the oxidative dyeing process, helping develop the final shade by linking the primary dye pigments to the hair’s keratin structure, thereby intensifying color depth.

What is the recommended application protocol for this hair dye, and does it contain any controversial chemicals?

Apply the mixed color and developer to dry, pre‑bleached or natural hair, leave for the time specified on the packaging (typically 30‑45 minutes), then rinse thoroughly; the product includes controversial ingredients such as ammonia, hydrogen peroxide, resorcinol, and fragrance components, which are regulated but may cause sensitivity in some users.
