The balm does not contain synthetic colorants, which can be irritants for some. However, its key ingredients are plant-based extracts like nettle and wormwood, which have a long tradition in hair care but may not suit everyone. The product's own guidance advises caution for those with very sensitive scalps or who react easily to herbal cosmetics.
The safest approach is to perform a patch test before incorporating it into your regular routine. Apply a small amount of the product to a discreet area of skin, such as the inside of your elbow or behind your ear, and leave it for 24 hours to check for any adverse reaction like redness or itching. If your scalp is currently irritated or inflamed, it's best to avoid applying any new cosmetic products until it has calmed down. As with any new product, if you experience discomfort, discontinue use.
