Step-by-step explanation:
The safety criteria for a permanent wave service typically involve several key practices and precautions to ensure both the stylist and client are protected during the chemical hair treatment process.
- Client Consultation: Before performing a perm, a thorough consultation should be conducted. This includes a discussion about the client's hair history, allergy tests, and a patch test to ensure there are no adverse reactions to the chemicals.
- Proper Use of Chemicals: It's vital to follow the manufacturer's instructions for the perm solution to avoid injuries and ensure optimal results. It's also important to use gloves to protect the skin from chemical exposure.
- Proper Ventilation: Ensuring the workspace is well-ventilated minimizes the inhalation of fumes from the perm solution.
- Timing: Careful monitoring of processing time is essential to prevent hair damage or scalp irritation.
- Post-Service Care: After the perm, the hair and scalp should be rinsed thoroughly to remove any remaining chemicals, and proper aftercare instructions should be given to the client.
