New study backs hair regrowth reduction claims

A new independent clinical study demonstrates a substantial reduction in hair regrowth following use of the no!no! Hair product, much to the joy of manufacturer Radiancy, a Photomedex subsidiary.

The product line uses proprietary Thermicon technology and has come under scrutiny in the past with regards to claims. This resulted in settlements and a curtailing of its advertising claims.

The new study, carried out by the Consumer Product Testing Company, found that there was a ‘substantial’ reduction in hair regrowth when using the no!no! Hair product, and the US manufacturer is looking to publish the results as soon as possible in a bid to boost the product’s reputation.

PhotoMedex CEO Dolev Rafaeli says, “We will closely evaluate the results of this study as a basis for expanding our advertising claims to provide consumers with accurate information about the safety and effectiveness of our no!no! Hair product line.”

Rafaeli explains that the decision to undertake this study was partly influenced by continued questions over the effectiveness of the product that led to a lawsuit that was later settled in 2012.

Study

The study included 44 subjects with Fitzpatrick skin types II-VI and with blonde, black and brown hair.

The subjects were treated on their arms and legs for 12 weeks. Quantitative hair counts were made by an independent evaluator reviewing a total of 160 treatment sites on the subjects over the course of three visits by each subject.

According to Photomedex, the results (p<0.001) of this clinical trial demonstrated a ‘substantial’ reduction in hair regrowth in the treated areas, and the company will seek to publish the results in a peer-reviewed journal in the near future or will otherwise make the final study report available on its website.

“Radiancy remains committed to demonstrating the validity of consumer testimonials and previous clinical studies as to the effectiveness and safety of the no!no! Hair product line, and confirms that with proper and continued use no!no! Hair provides safe, painless and long-lasting hair-removal results,” said a company statement.
