Evidence-based Review of Hair Removal Using Lasers

Wellaholic Research: Evidence-based Review of Hair Removal Using Lasers & Light-Sources

Wellaholic Research: Evidence-based Review of Hair Removal Using Lasers & Light-Sources

Wellaholic conducts in-house research on hair removal as part of our efforts to keep current with the latest hair removal technologies and trends. We also examine case studies, research reports from various dermatological journals and medical journals. This helps us to improve our hair removal treatments to improve efficacy, safety as well as comfort for Wellaholic’s customers who choose us as their hair removal service provider.

In this 2006 study by M Haedersdal and HC Wulf, a total of 9 randomised controlled trials and 21 controlled trials were conducted using a variety of diode lasers (including SHR), alexandrite lasers, ruby lasers, Nd:YAG lasers and IPL. The study concluded that partial long-term hair removal was achieved beyond 6 months after repetitive treatments for all laser types, while evidence was lacking for long-term hair removal with IPL treatments.

Background of Research

Unwanted hair growth remains a therapeutic challenge and there is a considerable need for an effective and safe treatment modality.

Unwanted hair growth remains a therapeutic challenge and there is a considerable need for an effective and safe treatment modality.

Objective of Study

From an evidence-based view to summarize efficacy and adverse effects from hair removal with ruby, alexandrite, diode, and Nd:YAG lasers and intense pulsed light (IPL).

Methods

Original publications of controlled clinical trials were identified in Medline and the Cochrane Library.

Results and Conclusion

A total of 9 randomized controlled (RCTs) and 21 controlled trials (CTs) were identified. The best available evidence was found for the alexandrite (three RCTs, eight CTs) and diode (three RCTs, four CTs) lasers, followed by the ruby (two RCTs, six CTs) and Nd:YAG (two RCTs, four CTs) lasers, whereas limited evidence was available for IPL sources (one RCT, one CT). Based on the present best available evidence we conclude that (i) epilation with lasers and light sources induces a partial short-term hair reduction up to 6 months postoperatively, (ii) efficacy is improved when repeated treatments are given, (iii) efficacy is superior to conventional treatments (shaving, wax epilation, electrolysis), (iv) evidence exists for a partial long-term hair removal efficacy beyond 6 months postoperatively after repetitive treatments with alexandrite and diode lasers and probably after treatment with ruby and Nd:YAG lasers, whereas evidence is lacking for long-term hair removal after IPL treatment, (v) today there is no evidence for a complete and persistent hair removal efficacy, (vi) the occurrence of postoperative side-effects is reported low for all the laser systems.

The evidence from controlled clinical trials favours the use of lasers and light sources for removal of unwanted hair. The study recommend that patients are pre-operatively informed of the expected treatment outcome.

SHR Hair Removal by Wellaholic

SHR or Super Hair Removal technology is a newer technology as compared to IPL. Developed by Alma Lasers, SHR combines 755nm, 808nm and 1064nm laser wavelengths to target all skin types. SHR‘s Advanced Fluorescence Technology (AFT) In-Motion laser hair removal technology is a breakthrough in customer comfort and effectiveness of treatments. SHR or Super Hair Removal technology heats the skin gently through the melanin and the stem cells with low energy but high frequency. SHR uses only 50% of the energy for permanent hair removal. The remaining 50% is absorbed into the stem cells responsible for hair production.

  • SHR uses only 50% of the energy for permanent hair reduction.
  • The remaining 50% is absorbed into the stem cells responsible for producing hairs. 
  • SHR’s Advanced Fluorescence Technology (AFT) In-Motion laser hair elimination technology is a breakthrough in customer comfort and effectiveness of treatments, and is known to be more effective and gentler on the skin as compared to the older IPL technology.
