Scalp treatment in Shoreline, WA —
at three depths.

Seattle asks a lot of a scalp. From October into May it lives under hoods, beanies and drizzle — covered, damp, rarely seeing air. Then summer flips the script and it's sun, sweat and trail dust until September. The guests at our Shoreline studio almost never describe the same scalp in January that they had in July, which is why we've stopped treating scalp care as one product at one price.

D4 Season opened here in 2022 as Seattle's first specialized head spa, and the years since have mostly taught us range. The studio at 15507 Westminster Way N Ste 7E, just off Aurora, has seen every version of a north-end scalp: hat-flattened February hair, post-hike August roots, and everything between. That history is why our menu spans $50 to $220 rather than clustering around one number.

So this page is organized the way our regulars actually book — by depth, not by scalp type. A quick reset when the week ran long. A deep clean when the scalp needs real work. The full revitalize when you want everything we know how to do in a single appointment. One caveat before any of it: we're a wellness studio, not a clinic. If something about your scalp worries you — soreness that lingers, patchy shedding — start with a dermatologist. We're the appointment after the all-clear, not before it.

Depth changes the dose, not the recipe. At every tier the session runs analysis, then targeted treatment, then massage, then conditioning. Even the 30-minute aromatherapy visit begins with a look at your scalp, because working blind is how a treatment ends up generic; on the longer tiers that look becomes a magnified analysis, and the cleansing, massage and conditioning stages each stretch to match the time booked.

The analysis is also where we'll tell you if you booked the wrong depth. It happens more than you'd think — someone reserves a quick reset out of caution and turns out to be carrying a winter's worth of residue, or books the deep clean when their scalp mostly needed quiet. Moving down a tier is instant; moving up depends on the day's schedule, so mention it at booking if you want the option held open. Either way, the session that happens should match the scalp in the chair, not the button you clicked online.

First visit and unsure where to land? The Signature ($85) or the Aura ($110) are the two we recommend most — enough depth to feel what the studio does, without committing to the full ritual. Hours are Monday to Saturday 10 AM to 9 PM and Sunday 10 AM to 8 PM; book through the Shoreline page or call (206) 688-9700 and describe what season your scalp is having. We'll place you in a tier from there.

Arrive with unwashed hair if you can stand it — the analysis reads truer that way — and give yourself a spare fifteen minutes after the longer sessions rather than sprinting back to the car. Four years of doing this in Shoreline has settled one thing for us: the treatment works better when the leaving is as unhurried as the lying down.
