Final answer:
A scalp massage is typically beneficial and recommended prior to most hair services, except for perming hair.
Step-by-step explanation:
A scalp massage is typically beneficial and recommended prior to most hair services, as it helps to relax the client and improves blood circulation to the scalp. However, it is best to avoid giving a scalp massage prior to perming hair.
Perming involves chemically altering the structure of the hair to create curls or waves. The massage can potentially disrupt the chemical process and affect the final outcome of the perm.
On the other hand, scalp massages are helpful before relaxing hair, coloring hair, and shampooing hair as they provide relaxation and improve the absorption of products.
