Waterpik™ HairWand PowerComb™ Spray: Quickly and Effectively Rinses Residue from Hair
A Clinical Study Evaluating the Efficacy of a Hand Held Shower Wand Spray for Hair-Residue Rinseability Compared to a Comparator* Product
Objective
To determine the effectiveness of the Waterpik™ HairWand Spa System handheld shower wand device in rinsing residue from hair with its proprietary Powercomb™ hair-rinsing spray. Effectiveness was also measured vs. a comparator* product representing a standard shower device.
Methodology
Thirty-Four (34) healthy males and females, 21 – 65 years of age, hair types from straight to coily were enrolled into the 2- day randomized, comparative, crossover clinical study.
At each period visit, a fluorescing hair care product was applied to hair of each subject by a technician. After application to a common and specific location in the hair, the study products (shower units) were used per sponsor instructions one time in-clinic to rinse the hair. One smooth, controlled, uninterrupted pass of approximately 1.5 seconds duration was made along the treated hair.
An expert grader evaluated the hair pre-use and immediately after use for rinsing effectiveness at Period 1 and Period 2 of the crossover for each respective product. Clinical photography was taken for a subset of 6 subjects after use of both test and comparator* products.
Results
In a single uninterrupted pass of approximately 1.5 seconds, expert grading revealed immediate, statistically significant reduction of residue from the hair.
The Waterpik™ product significantly outperformed the comparator* product’s hair rinsing spray.
Conclusion
Clinical use of the HairWand PowerComb™ spray resulted in significant rinsing of residue from hair in 1.5 seconds which is considered both effective and fast. The PowerComb™ spray was more effective than a market-leading comparator* product in this study.
*Comparator product: Delta In2ition Combo Shower Head, Model # 75583C
