If a client experiences adverse reactions to the lash extension procedure after signing a Lash Tech Consent Form, the lash technician should immediately contact the client and inform them of the situation. The technician should also provide medical advice and assistance to the client if necessary. Depending on the severity of the adverse reaction, the technician may need to refer the client to a medical professional for further evaluation and treatment. Sometimes, the technician may need to remove the lash extensions and provide a refund or credit to the client for any services rendered. The technician should also document all incident details in their records and report it to their insurance provider if applicable.
