M any studies have investigated hair removal or growth prevention treatments, but they often measure hair density using noninvasive methods that are subjective and qualitative. Although photographic and digital hair-counting methods have been used, their reliability and validity remain unknown. We describe a simple, noninvasive method of hair counting used in a hair growth prevention treatment ...

BACKGROUND The uniform delivery of laser energy is particularly important for safe and effective laser hair removal (LHR) treatment. Although it is necessary to quantitatively assess the spatial distribution of the delivered laser, laser spots are difficult to trace owing to a lack of visual cues. This study proposes a novel preclinic tool to evaluate operator proficiency in LHR treatment and a...

This article describes a systematic literature review on whether, how, and when to perform preoperative hair removal. By searching electronic databases and reference lists of relevant articles, team members identified 20 clinical studies that deal with preoperative hair removal. No strong evidence was found to advocate against preoperative hair removal. Furthermore, there was strong evidence to...

We are in a state of evolution in long-term hair removal. Safe and effective technology is now available. Lasers will always become smaller, faster, and perhaps more effective. For those interested in offering this procedure, evidence indicates that we are beyond the experimental phase. The treating physician should carefully review current available technology and receive proper training speci...

The recent rapid growth in demand for non-invasive light-based cosmetic treatments such as removal of unwanted facial and body hair, skin rejuvenation, removal of age-related and sun induced blemishes including pigment and vascular lesions as well as lines and wrinkles has led to a boom in the sale of medical devices that claim to treat these conditions. The often onerous safety regulations gov...

BACKGROUND Diode lasers with high fluence and cooling technology are effective at removing unwanted hair but are also associated with discomfort and morbidity, especially when treating dark or tanned skins. METHODS Thirty patients with skin phototypes IV and V (range: 23-62 years of age; average: 39 years) underwent a single hair removal treatment using a new diode laser (810 nm) technology t...

Hirsutism is a common problem in dermatology that imposes high socioeconomical costs on medical care. Consequently, researchers are actively searching for cheaper and safer methods for therapeutic treatment. The objective of the present study is to evaluate formic oil, enriched from formic acid, for the removal of unwanted hair. In this study, 32 female rats (150-200 g) were randomly divided in...
