D4 Season was established in 2022 as Seattle's first specialized head spa, with two top-rated studios in Shoreline and Lynnwood, WA. Inspired by the four seasons, D4 Season brings scalp therapy, body massage, and skin care together under one roof, offering treatments rooted in Japanese scalp care traditions. From deep-cleansing head spas and hydrotherapy to Swedish massage, HydraFacial, and luxury La Mer facials, every service is designed to help guests feel calm, refreshed, and beautifully balanced. Both studios share the same full menu and pricing, welcoming individuals and groups alike. Whether you're seeking relief for a dry scalp or simply an hour of uninterrupted relaxation, D4 Season is built to deliver the gentlest, most attentive care possible.
