This mask is designed for the hair, not specifically for the scalp, but the allantoin in it has a soothing and softening action that can help the scalp feel calmer. If your scalp is dry or irritated, you can apply a small amount to the roots, but it is not a scalp treatment and should not be used as one on a regular basis.
For most people, it is better to focus the mask on the mid-lengths and ends, where hair is driest and most prone to damage. Applying it to the scalp can weigh down the roots, especially if your scalp is oily. If you do apply it to the scalp, massage it in gently and rinse thoroughly.
Before using it on your scalp, do a patch test on a small area of skin, such as behind your ear, and wait 24 hours to check for any reaction. Avoid contact with the eyes, and if you have a very sensitive scalp or a skin condition, consult a specialist before use.
This mask is not intended to treat scalp conditions like dandruff, psoriasis, or eczema. If you have such a condition, talk to a doctor or dermatologist before using any new hair product.
