What should a practitioner ensure before applying a chemical service to a client?

Before applying a chemical service, it is crucial for a practitioner to ensure that the client's scalp is free of abrasions. This step is essential for several reasons. First, any open cuts or abrasions on the scalp can serve as entry points for chemicals, which may lead to irritation or severe chemical burns. Assessing the scalp beforehand protects the client’s health and well-being.

Additionally, performing a chemical treatment on broken skin can compromise the effectiveness of the service, as the chemicals can react differently when applied to damaged skin compared to healthy skin. By checking for abrasions, practitioners demonstrate their adherence to safety protocols, further ensuring a positive experience for the client.

While having clean hair can be beneficial, and knowing a client’s service history is important, these factors do not address immediate health risks associated with the application of potentially harsh chemicals on compromised skin. Long hair may also be a consideration for certain services, but it is not directly related to the safety of applying chemical products. Thus, ensuring the scalp is free of abrasions is the most critical step in the process.
