More than a massage
Most head spas focus on relaxation. We start there too, and then go further. Every head spa treatment at Cosh begins with a scalp analysis, so your specialist can see what's going on (buildup, oil, dryness) and tailor the session to it.
You still get the part everyone comes for: an unhurried scalp massage, a double shampoo, and a hydrating mask with steam. You also leave with a clear picture of your scalp and simple recommendations for home care.
How a visit works
- Consultation and scalp analysis. Your specialist looks at your scalp up close and asks about your routine.
- Scalp massage and double shampoo. A relaxing massage, then a thorough double cleanse.
- Exfoliation and gua sha (Detox and up). A pre-shampoo scrub lifts buildup most people can't reach at home, and gua sha adds a tension-relieving finish.
- Mask and steam. A hydrating hair mask with warm steam, then conditioner.
- Finish and recommendations. A rough dry, a post-treatment scalp check, and home care suggestions.

Questions
What is a head spa?
A head spa is a treatment focused on the scalp: massage, cleansing and conditioning in a relaxing setting. At Cosh, every head spa treatment also starts with a scalp analysis.
Is this a Japanese head spa?
Our treatments are Japanese-style: a relaxing scalp massage, a thorough cleanse, and steam. We add a scalp analysis at the start so the treatment fits your scalp.
Which treatment should I book first?
Detox. It includes scalp exfoliation, which most people don't do at home, and gives your specialist a full picture for future visits.
How long does it take?
60 minutes (Refresh) to 2 hours (Revive).
Should I wash my hair before I come?
Please don't wash your hair within 24 hours of your appointment. It lets your specialist see your scalp as it normally is during the analysis.
Where do I park?
There are two paid lots across the street (Lot B-1 at 1421 Chapin Ave and Lot B at 1441 Chapin Ave) and metered street parking nearby. See our Location & Parking page for a map.
Will my hair be styled afterward?
Treatments finish with a rough dry, not a styled blowout, so plan accordingly if you have somewhere to be.
How do I book?
Online, in a few minutes. A $50 deposit holds your appointment and the balance is paid after your visit.
