Can I really use this on my hair? How will it behave compared to shampoo?

The product is described as suitable for body cleansing in the shower, bath or sauna, with the added bonus that it can also be used on hair. On the scalp and hair, it acts as a cleansing wash rather than a heavy conditioning product. That means it will remove sebum, sweat and product buildup, but it will not provide the same detangling or smoothing effect as a dedicated conditioner or a shampoo with high levels of conditioning agents.

If you have normal or oily hair, this type of soft soap can be a practical multi-use option, especially at the gym, in a country house or after steam bathing, where you may not want to carry several bottles. If your hair is long, dry, chemically treated or prone to tangling, plan to follow with a separate conditioner or a leave-in product. You should also pay attention to how your scalp feels over time: some people find that a gentler, soap-based wash is less irritating than a strong sulfate shampoo, while others may need a more specialized scalp care product.

To use it on hair, wet the hair thoroughly, massage a small amount into the scalp and lengths, then rinse well. Because the texture is soft and not as thick as typical shampoo, you may need to adjust the amount. Avoid getting it into the eyes, and if you use it on both scalp and body regularly, observe how your skin and hair respond over a few weeks.
