WaterpikTM HairWand Pulsating Wand Massage Spray: Efficacy on Scalp Stimulation and Flake Removal

A Clinical Study Evaluating the Efficacy of a Shower Wand Pulsating Massage Spray on Scalp Stimulation and Flake Removal

Independent Clinical Testing, March, 2022, VCS 211009


To determine the effectiveness of the WaterpikTM HairWand Pulse Spa System with the pulsating massage spray in the handheld wand device, in promoting scalp stimulation and reducing scalp flakiness.


Forty-five (45) healthy females and males, 25 – 65 years of age with hair types from straight to coily were enrolled into the 24-hour randomized comparative, clinical study. The study was conducted under an independent investigational review board.

After screening, subjects were given a control shampoo and conditioner to use during the 7-day washout period, and were instructed to not wash hair, nor apply styling products for 3 days prior to baseline evaluation. Each subject underwent technician-supervised use of the hair wand in pulsating massage spray setting for 2 minutes on their hair/scalp, working from front hairline to back of the head in a consistent application method and distance. Applications were completed on site in a shower stall with monitored water pressure (>45 psi) to maintain consistent conditions across all subjects.

An expert grader evaluated the scalp pre-use (Baseline), 3-hours and 24-hours post use. All subjects provided self-assessment of hair and scalp sensory attributes at intervals of 5-minutes, 30-minutes, 60-minutes, 3-hours, and 24-hours via a subjective questionnaire.


Expert visual grading revealed statistically significant reduction in appearance of visible flaking after single use at 3 and 24 hours compared to baseline. The Expert grader observed reduction in visible flaking in 75% of the subjects.

Immediately after a single 2-minute use of the handheld shower wand pulsating massage spray, 83% of subjects reported that their scalp felt stimulated and 75% reported a reduction in visible flakes.


Clinical Study showed that use of pulsating massage spray from the wand device in the HairWand Pulse Spa System for 2 minutes, helped to reduce visible scalp flakiness and study participants said it provided a stimulating scalp massage.
