What percentage of overlapping is recommended when performing laser hair removal (LHR)?

The recommended percentage of overlapping when performing laser hair removal is typically around 30%. This is important because proper overlap ensures that the entire treatment area receives adequate coverage, reducing the risk of missed spots where hair follicles may not be effectively treated. With a 30% overlap, each pulse overlaps with the previous one enough to maintain consistent energy delivery across the skin, which is crucial for achieving effective hair reduction while minimizing discomfort and ensuring safety.

Overlapping too little may leave gaps in treatment and can result in uneven hair removal, leading to the possibility of having hair regrowth in untreated areas. Conversely, overlapping too much may lead to unnecessary skin irritation or increased risk of side effects. Therefore, a balanced approach with about 30% overlap is generally advocated in practices to optimize outcomes while preserving patient comfort and skin integrity.
