When laser causes more hair, not less

Paradoxical hypertrichosis means increased hair growth after laser or light hair removal. It's uncommon, but it worries clients far more than its frequency suggests, and it's often confused with more ordinary problems. This masterclass explains what it is, how to tell it apart from synchronised regrowth, white hair and under-treatment, and what the published research says about how common it is and who's at risk. You'll learn where the evidence is solid and where it's uncertain, which theories explain why it may happen, and practical steps to reduce the risk. We also cover the disagreement over whether to pause or continue treatment, and how to handle the client conversation and the records. Finish with a short quiz and download your certificate of completion. Suitable for laser technicians at any stage, and for clinics training their teams. This is a knowledge course with a certificate of completion, not a formal qualification.
