My scalp reacts easily to new products — what should I watch for with this shampoo? — Shampoo for oily hair with aloe vera and birch 200ml

The shampoo uses a milder, sulphate-free cleansing base with aloe vera for a softer wash, which many people with reactive skin tolerate well. However, the product information explicitly states that you should be extra cautious if your scalp is very sensitive or reactive, and stop use if irritation appears. This is standard guidance for any cosmetic applied to the scalp. Practical steps: do a patch test on a small area behind the ear or on the inner forearm before full use, especially if you have a history of contact dermatitis or fragrance sensitivity. Avoid contact with eyes, and rinse thoroughly if contact occurs. If you have a diagnosed scalp condition such as seborrheic dermatitis, psoriasis, or eczema, consult a dermatologist before adding a new cleanser to your routine.
