Hi Dano,
I wonder about the hair salon inside Providence Mount St. Vincent (aka The Mount) at 4831 35th Ave SW. Some extra services offered to residents at The Mount are available to the public. The main switchboard number is 206-937-3700.
Another thought: You can get a “Gold Card for Healthy Aging: Access to senior services and discounts” (offered by Seattle-King County). They may list a local hair salon offering discounts for seniors. You can pick up one of these cards for free at Senior Center of West Seattle and they may also have a list of all the discounts.
You might also check with Illusions Hair Salon on California Ave. They’ve been in business a long time and cater to all ages and all styles. Very nice people who have a lot of very happy customers. They are a no-tipping salon. 206-938-3675
