Which product is often used for scalp massage during a haircut?

Hair oil or conditioner is commonly used for scalp massage during a haircut because these products help to moisturize and nourish the scalp and hair. They can provide a soothing effect that enhances the overall experience for the client. The massage itself promotes relaxation, improves blood circulation in the scalp, and helps in the distribution of the product along the hair strands, which can lead to a healthier look and feel.

Using gel or mousse is typically intended for styling rather than for scalp care or massage. Hairspray is primarily used to hold a hairstyle in place and is not suitable for use during a massage as it can make the hair stiff and sticky. Water can be refreshing and hydrating but doesn’t provide the lubrication or nourishing benefits that hair oil or conditioner offer during a massage technique. This makes hair oil or conditioner the most appropriate choice for scalp massages in the context of a haircut.
