Yes, and it is mandatory before your first use. Wooly contains p-Phenylenediamine (PPD), a colourant active used in professional hair colour. Apply a small amount behind the ear or on the inner forearm, wait 48 hours, and proceed only if there is no reaction. Wooly is not recommended for sensitive or allergy-prone skin.

One 180ml bottle lasts up to 20 washes depending on hair length and thickness — up to 22 washes for short hair.

We recommend consulting your doctor before using any hair colour product during pregnancy. Wooly is free of ammonia but does contain colourant actives — your doctor's guidance applies.
