Although lasers have been more closely associated with hair removal in the past, the company claims that clinical tests have proved its HairMax LaserComb can promote hair growth in males with androgenetic alopecia. Now those claims have been given further credence after the FDA gave clearance for the product - a feat that has only been given to two other products marketed to combat hair loss. The company says that the product is easy to administer - requiring sessions of 10 - 15 minutes three times a week, and is an alternative to other topical and drug products marketed for the same purpose. Costs over $500, the product is not cheap, but the company says that the efficacy of the product is backed up by extensive clinical tests. Those tests were conducted in four locations across the US and concluded that 93 per cent of the males aged 30 - 60 used in the study experienced a distinct increase in the number of terminal hairs found on the scalp. The study suggests that the average number of hairs increased by 19 per square cm over a six-month period. The company says that further clinical tests are currently being carried out on women to see if the product has the same efficacy, results of which will be submitted to the FDA. "Not only were the results of this study extremely significant, but with the credibility of the FDA clearance, we are soundly positioned to make a substantial impact on the emerging hair restoration industry," said David Michaels, managing director of Lexington International. Light- or laser-based personal care technology is currently the talk of the industry, with P&G recently making significant investments in laser-based technologies. At the end of February the company announced that it was entering into a joint venture with Israeli company Syneron to develop its elos technology - combining energy from bi-polar, radio frequency and light sources to combat signs of aging.The move came just days after P&G announced that its Gillette division was making a $1.5m investment in US company Palomar to develop its light-based hair removals technology for home-use. Likewise, another company recently launched a light-based anti-aging laser treatments for home use. Called Rejuvawand and produced by Light Dimensions, it relies on red lasers to stimulate collagen growth and improve skin structure. As a result in all of this activity in laser technology for the personal care field, the FDA says that it is has been flooded with applications from company's marketing these kind of products and seeking approval.
