This shampoo is not an automatically good choice for every sensitive scalp, because the essential oils and capsicum extract are active ingredients that can be felt on the skin. The product information itself says that if your scalp is very sensitive, these ingredients may feel active and you should watch your personal response and avoid use if irritation appears.
Before using it on the whole head, do a small test. Apply a little shampoo behind the ear or at the nape of the neck, leave it for a few minutes, rinse and watch the area for the rest of the day. If there is no itching, redness or discomfort, you can proceed. Start by using the shampoo only once or twice a week so your scalp has time to adjust. Keep the contact time short; there is no need to leave it on after massaging.
A warming or tingling sensation is possible with capsicum extract and certain essential oils. This is not a sign that the product is cleansing better; it is just a sensory effect. If the sensation becomes painful or the skin becomes red or irritated, stop use, rinse thoroughly with lukewarm water and avoid the product afterwards. If you have a diagnosed scalp or skin condition, or if you are under dermatological care, do not use this shampoo as a replacement for your treatment; ask your doctor first. It is a cosmetic cleansing product, not a medicine or a treatment for any scalp condition.
For anyone who is pregnant, breastfeeding, taking medication, or under medical supervision, a quick conversation with a specialist before introducing a new scalp product is the safest approach.
