Why contra-indications can affect the scalp massage service?

Contra-indications can affect the scalp massage service because they indicate underlying health issues that may be exacerbated by the treatment. Conditions such as skin infections, open wounds, or certain medical conditions like hypertension could lead to complications or discomfort during the massage. Additionally, clients with contraindications may require alternative treatments or modifications to ensure their safety and well-being. It's essential for practitioners to assess and address these factors before proceeding with the service.
