Is this shampoo completely fragrance-free, and why does that matter for a sensitive scalp?

This formula is fragrance-free, meaning no synthetic perfume or essential oils are added to mask the base scent. For people whose scalp turns red, itchy, or tight after washing, fragrance is one of the most common irritants in conventional shampoos. Removing it reduces the chance of a contact reaction and makes the product a safer daily choice for reactive skin. The calendula extract further supports a calmer feel — it has a long tradition in topical products for its soothing character and helps the scalp tolerate frequent cleansing better. If you have a known fragrance allergy or contact dermatitis, this shampoo avoids that trigger entirely. Still, even fragrance-free products can contain other ingredients that rarely cause sensitivity, so if your scalp is very reactive, introduce it alone (not alongside a new conditioner or treatment) and watch for any irritation over the first few washes.
