The mask contains active ingredients, so it is not intended for careless use on very sensitive skin. According to the product notes, you should pay attention to skin sensitivity. If your scalp is very reactive, irritated or damaged, the advice is to introduce the product gently and stop using it if discomfort appears. You should also keep the product away from the eyes.
A patch test before the first full use can be useful. Apply a small amount to a discreet area of skin, for example the inner forearm or behind the ear, leave it for the time you would normally leave the mask on, and rinse. Watch that area over the next day to see whether redness, itching or irritation develops. This is a general precaution that is especially helpful for anyone who has reacted to scalp cosmetics in the past.
If you have a chronic skin condition, are pregnant or breastfeeding, or are taking medication that affects your skin, consult a specialist before introducing an active product. The mask can still be a reasonable choice for many people, but a professional can give advice based on your specific situation.
