Final answer:
In the event that a perm solution does not result in curl formation after 10 minutes, review the procedure, consider hair type and condition, rinse the solution, condition the hair, and consult with the client for next steps. Do not reapply immediately to avoid damage.
Step-by-step explanation:
If you have applied a perm solution to a client's hair and there is no curl formation after 10 minutes, you should first review the procedure to make sure that the solution was applied correctly and that the correct processing time has been followed. Different hair types and the condition of the hair can affect the processing time, so it might need more time. However, if no curls are forming after the recommended processing time or if the hair is not responding as expected, you should gently rinse out the solution to prevent any potential damage to the hair.
Always conduct a thorough consultation before any chemical service to ascertain hair history and texture, as this can affect how the hair reacts to chemicals. Do not attempt to reapply the perm solution without understanding why the hair did not respond in the first place; this could lead to hair breakage or scalp irritation. After rinsing, condition the hair to help restore its natural pH balance. It's also important to discuss the next steps with your client, including the possibility of reattempting the perm after an appropriate amount of time or exploring alternative styling options.
