Salon and Pet Grooming Spray Heads Introduction

Water used to wash and rinse hair represents a major portion of water use in hair salons and the greatest portion of water used in pet grooming.  Existing salon and pet sprayers can have maximum flow rates as high as 5.0 Gallons Per Minute (gpm) (19 Lpm), but often average approximately 4.0 gpm (15 Lpm) at the highest flow settings.   It is reasonable to assume that this flow rate may be far more than necessary to wash and rinse hair, therefore, the savings potential could be very large.  Anecdotal evidence from the field suggests salon operators rarely use the maximum flow rate, usually regulating the flow down to approximately 2.5 gpm (9.5 Lpm).   This is not to say improved efficiency is not possible.   Since salon spray heads consume hot water, there are also energy savings that can improve the cost-effectiveness of replacing traditional spray heads with more efficient designs.

To date, most salon sprayer manufacturers have focused their product design only on performance, with little regard for water use.  Traditional salon sprayers are designed for ease of use by the stylist, the ability to quickly remove shampoo and dyes from hair, and comfort for the customer.  Similar to pre-rinse spray valves used on commercial dishwashing, the removal of shampoo from hair depends on a combination of water velocity and volume.  Increasing the velocity of the water emitted from the salon sprayer allows for reduced water volume, resulting in improved water efficiency while improving the effective performance.

There are limits to the practical water velocity of spray heads used to wash hair or pets.  Unlike pre-rinse spray valves used on dishware, using higher velocity water sprays could cause serious discomfort to the salon customer or pet, and produce intolerable splash patterns as water deflects off the head and hair during rinsing.   Any new developments in salon spray head efficiency will be posted on this page.
