With what part of the hand are shampoo and scalp manipulations performed?

Shampoo and scalp manipulations are performed using the cushions of the fingertips because they provide a gentle and effective way to apply pressure and stimulate the scalp without causing discomfort to the client. The cushioning of the fingertips allows for increased control and better tactile sensitivity, making it easier to perform techniques that promote relaxation and circulation in the scalp. This technique ensures that the client receives a soothing experience while also effectively cleaning the hair and scalp.

While other parts of the hand, such as the palms, can be used during shampooing, they do not offer the same level of precision and gentle pressure as the fingertips' cushions. Fingernails should be avoided to prevent scratching the scalp, and the pads of the fingers are less effective in creating a thorough and soothing motion compared to the cushions. Therefore, using the cushions of the fingertips is the most appropriate method for performing shampoo and scalp manipulations.
