Hair counts were obtained manually by two independent observers marking terminal hairs under magnification. A single treatment was carried out on 25 study sites with a 3-msec alexandrite laser at 755 nm using fluences of 30 to 50 joules/cm(2). A designated period for follow-up was used to address the issue of long-term benefits. The purpose of this study was to assess the degree of hair loss attained by a single treatment with a 3-msec alexandrite laser. Since many patients desire permanent hair loss, there is a need for specific information on the exact benefits and limitations of each particular system. Most of the published studies use follow-up periods of 6 months or less after the last treatment and cannot address the issue of permanency. All of the laser systems presently being used produce a reliable temporary hair loss by inducing telogen. Laser epilation is now used widely as a clinical alternative to electrolysis for the removal of unwanted hair. Long-term hair removal using a 3-millisecond alexandrite laser. Although the field of optical hair removal is still in its infancy, initial reports of long-term efficacy are encouraging. Treatment and safety guidelines are provided to assist the practitioner in the use of these devices. This article provides a detailed explanation of the scientific underpinnings for optical hair removal and explores the advantages and disadvantages of the various devices currently available (Nd:YAG, ruby, alexandrite, diode lasers, and xenon flashlamp). However, significant controversy and confusion surrounds this field. Aggressive marketing of these has contributed to their popularity among patients and physicians. In the last few years, several lasers and xenon flashlamps have been developed that promise to fulfill the need for a practical, safe, and long-lasting method of hair removal. Traditional methods of hair removal have proven unsatisfactory for many individuals with excessive or unwanted hair. Laser Hair Removal In this method, a laser destroys hair. related to common methods of hair removal.

Our results show that the algorithm we have developed is extremely fast (around 45 milliseconds) allowing for real-time application with high accuracy hair localization ( 96.48 %). We compare our algorithm with competing methods in terms of localization performance and computation time and show that a much faster real-time accurate localization of hair regions is possible with the proposed method. Proposed methods are based on certain features derived from histograms of hair and skin regions. Unlike previous limited number of studies, our methods are very fast allowing for real-time application. This study proposes a new system of algorithms to detect hair regions with the help of a digital camera. Therefore, methods that can distinguish hair regions automatically would be very helpful avoiding these unnecessary applications of laser. Thus, a significant portion of the skin, where hair is not present, is burnt unnecessarily causing health risks. In most cases, these devices irradiate the whole area of the skin with a homogenous power density. Laser-assisted hair removal devices aim to remove body hair permanently. Hair and bare skin discrimination for laser-assisted hair removal systems.
