Shoreline D4 SEASON

Shoreline D4 SEASON is a head spa studio in Shoreline, Washington, known for scalp analysis, scalp massage and warm-water hydrotherapy.

Every visit starts with a close look at your scalp, and the treatment is matched to what it needs. Depending on the service, that can mean exfoliation, a deep-cleansing wash, a long scalp-and-shoulder massage, hydrotherapy and conditioning, usually finished with a blow-dry. The D4 Signature Head Spa is the usual first booking: 60 minutes, from $85. The menu also includes a Chinese Herb Head Spa, a 30-minute TCM Head Aromatherapy and the Floral Head Spa Therapy, which uses botanical flower extracts and aromatherapy.

The studio also offers body massage, facials such as gua sha and HydraFacial, and packages that pair a head spa with a massage or facial. It opened in 2022 and calls itself Seattle's first specialized head spa. A sister studio in Lynnwood runs the same menu. Reviewers praise the relaxing feel, the friendly, attentive staff and a scalp that feels clean afterward. A few note that treatment areas are close together and divided by curtains.

It suits first-timers, regulars who want ongoing scalp care, and friends or couples who want to book together. The Shoreline studio can host several head spa treatments at once.
