Are there any precautions if I have a sensitive scalp or reactive skin?

The formula does not contain parabens or colorants, which reduces the number of common irritants, but individual sensitivity can still occur with any cosmetic ingredient. If you have a history of reactive scalp or contact dermatitis, do a patch test first: apply a small amount behind the ear or on the inner forearm, leave for a few minutes, rinse, and wait 24 hours. When using on the scalp, apply sparingly and rinse thoroughly — the product is primarily designed for the hair shaft. Avoid contact with eyes; if it happens, rinse immediately with plenty of water. If you notice redness, itching, burning, or increased flaking after use, stop using the product and seek advice from a dermatologist or pharmacist. This is standard caution for any new hair care product, not a signal that this specific formula is higher risk.
