Wellaholic Research: Safety & Efficacy of SHR Laser Hair Removal in Chinese Women



Background & Objective

High-fluence diode lasers with contact cooling have emerged as the gold standard to remove unwanted hair. Lowering the energy should result in less pain and could theoretically affect the efficacy of the therapy.

Objective: To compare the safety and efficacy of a low fluence high repetition rate 810-nm diode laser to those of a high fluence, low repetition rate diode laser for permanent axillary or underarm hair removal in Chinese women.


​Ninety-two Chinese women received four axillae or underarm laser hair removal treatments at 4-week intervals using the low fluence, high repetition rate 810-nm diode laser in super hair removal (SHR) mode on one side and the high fluence, low repetition rate diode laser in hair removal (HR) mode on the other side. Hair counts were done at each follow-up visit and 6-month follow-up after the final laser treatment using a “Hi Quality Hair Analysis Program System”; the immediate pain score after each treatment session was recorded by a visual analogue scale.


​The overall median reduction of hair was 90.2% with the 810-nm diode laser in SHR mode and 87% with the same laser in HR mode at 6-month follow-up. The median pain scores in SHR mode and in HR mode were 2.75 and 6.75, respectively.


Low fluence, high repetition rate diode laser can efficiently remove unwanted hair but also significantly improve tolerability and reduce adverse events during the course of treatment. This leads to higher heat safety but yet ensuring efficacy of treatments for Asian skin.

A: The number of sessions required varies based on factors like hair thickness and the treated area. However, many individuals begin to notice significant hair reduction after a few sessions. A full treatment course is generally recommended for optimal results.

Does SHR Laser Hair Removal work on fine or light hair in Chinese women?

A: Yes, one of the advantages of SHR Laser Hair Removal is its ability to effectively target even fine or light hair, which can be challenging for some other methods. This makes it a versatile choice for Chinese women.

A: SHR Laser Hair Removal is known for its comfortable experience. While individuals may feel a mild warming sensation, it is generally painless and well-tolerated.
