Hair Removal Practices: A Literature Review

A team of authors from the University of Toronto, Canada, has provided a review of hair removal techniques, their efficacy, and the associated considerations. Hair removal methods can be broadly categorized into two distinct groups: depilation and epilation, each presenting its own set of merits, drawbacks, and potential adverse effects.
Depilation methods focus on the removal of the hair shaft and encompass techniques such as shaving and the use of chemical depilatories. Epilation, on the other hand, goes a step further by eliminating the entire hair shaft, follicle, and bulb. This category includes methods like plucking, threading, waxing, sugaring, lasers, intense pulsed light systems (IPL), electrolysis, and photodynamic therapy. Notably, only laser and electrolysis methods yield the permanent results. An additional option worth mentioning is topical eflornithine. While it doesn't fit into the epilation or depilation categories, it does play a role in slowing down facial hair growth when used in conjunction with other techniques.
Many individuals face with the persistent issue of unwanted, residual hair, and traditional hair removal methods such as shaving and waxing have historically offered only temporary solutions with often unsatisfactory results. Laser therapy emerges as a safe and effective modality capable of delivering permanent results for some individuals. However, it's essential to note that electrolysis, another method offering permanent hair removal, can be laborious and is associated with several potential adverse events. Importantly, studies exploring the efficacy of hair removal techniques are largely limited to individuals with darker hair and fairer skin. In such cases, precautionary measures, including the use of cooling devices, are recommended to ensure safe and effective treatment.
