The primary purpose of performing a scalp massage during a shampoo service is to stimulate circulation and promote relaxation. This practice has several benefits:

1. **Circulation**: Massaging the scalp increases blood flow to the hair follicles, which can promote healthier hair growth. Improved circulation brings more nutrients and oxygen to the surface of the scalp, thereby supporting overall hair health.

2. **Relaxation**: The act of massaging can also have soothing effects, helping clients to relieve stress and tension. This enhances the overall experience of the shampoo service, making it not just a cleansing treatment, but also a moment of relaxation.

3. **Lathering and Cleansing**: While the massage does contribute to the effectiveness of the shampoo by helping the product distribute more evenly across the scalp, the main goal is always to provide those beneficial effects on circulation and relaxation, rather than merely focusing on product removal or lathering.

The other choices, while they may have some relevance to shampooing and hair care, do not capture the primary intent behind performing a scalp massage during the service.
