I have a sensitive scalp and react to fragrance — can I use this safely?

The product contains fragrance (parfum) and botanical waters (sage flower water, green tea extract), both of which can trigger reactions in fragrance-sensitive or atopic individuals. The manufacturer advises: "If your scalp is sensitive, or if you react easily to fragranced products, it is wise to test first and keep the balm mainly on the hair lengths rather than the roots." Practical steps: do a patch test behind the ear or on the inner forearm with a small amount, leave for 10 minutes, rinse, and wait 24 hours. If no itching, redness, or burning occurs, proceed with length-only application. Use a headband or clip to keep hair off the face while the product sits, preventing transfer to forehead or temples. Rinse thoroughly with lukewarm water — hot water opens cuticles but also increases scalp permeability. If you have a diagnosed condition like seborrheic dermatitis, eczema, or psoriasis, consult a dermatologist before introducing any new leave-on or rinse-off hair cosmetic, even one marketed as gentle. This product is not medicated and does not treat scalp conditions; it's a hair-fibre care product. For daily maintenance between washes, consider a fragrance-free scalp tonic or water-only rinse if your scalp reacts to frequent washing.
