What should be used when performing a scalp massage on a client?

Using fingertips when performing a scalp massage on a client is the most effective choice. Fingertips are ideal for this technique because they allow for delicate and precise pressure, which can stimulate the scalp and promote relaxation without causing discomfort. This method also enables the cosmetologist to access different areas of the scalp easily and apply varying levels of pressure based on the client's comfort and preferences. Additionally, fingertips facilitate gentle circular motions that enhance blood circulation in the scalp, which can be beneficial for hair health and overall relaxation.

Other options, such as using knuckles or elbows, may not provide the necessary finesse for an effective scalp massage. Knuckles could apply too much pressure and lack the gentle touch required, while elbows are not suitable for this delicate area, as they cannot achieve the same level of control or comfort. Palms can be used, but they may not offer the same targeted sensation that fingertips do, making them less effective for stimulating the scalp.
