Start with this one
New to head spas? This is the guide we send people first: what happens in a 60 minute session, step by step, and what a head spa can and cannot do for your scalp.
Head Spa Basics
What is a head spa? Every step, explained
A head spa treats the scalp the way a facial treats the skin: it looks first, cleans deeply, then spends a long stretch on massage and warm water. Here is what each step does, what O2's 4 packages include, and when to see a dermatologist instead.

The full series
Browse all 10 guides
The rest of the series covers scalp massage and hair, gua sha, tui na and acupressure, tension headaches, stress, sleep, back pain and chronic pain. Every guide has the same shape: a short answer up top, sourced sections below, and a plain note on where the research is strong and where it is thin.
Evidence Check
Does massage help back pain? What the studies show
The research on back and neck pain points to relief that is real but modest and mostly short-term. Here is what the major reviews found, how long a session needs to run, and where massage fits next to medical care.

Living With Pain
Massage for chronic pain: where it fits in a plan
One in five American adults lives with chronic pain. The evidence for massage is thinner than most people assume, and more specific about when it helps.

Evidence Check
Massage for stress and anxiety: what it can and cannot do
One massage reliably lowers in-the-moment anxiety, heart rate and blood pressure. The popular cortisol claim is far weaker, and none of it replaces care for an anxiety disorder.

Evidence Check
Massage for sleep: does it help, and how much?
The trials are mixed: massage calms a body that won't settle, but direct proof that it deepens sleep is thin. Here is where the evidence lands, and what to do tonight.

Gua sha facial benefits: what the research shows
Gua sha began as a body treatment that leaves red marks on purpose. The facial version is lighter and far less studied, so here is what the trials found, where they stop, and who should skip it.

Traditions
Tui na massage benefits: what the evidence says
Tui na is the hand-based massage of traditional Chinese medicine, and acupressure is its point-by-point relative. Trial reviews now give tui na some direct support for chronic low back pain, at low certainty. Here is what that means, and what O2's menu does and does not offer.

Self-Care
Tension headache relief: what actually works
The habits with the best track record are the plain ones: steady sleep, regular meals, water, moderate caffeine, and knowing when painkillers start causing headaches of their own.

Evidence Check
Scalp massage for hair growth: what the evidence shows
Two small studies get quoted on almost every head spa page. Here is what they measured, where they fall short, and what a scalp treatment can reasonably offer.

Self-Care
Relaxation techniques that hold up between spa visits
The calm from a head spa, facial or massage tends to fade by the next busy morning. The relaxation response behind it can be practiced at home. Here are the 4 methods Mayo Clinic describes, how to do each one, and what a 60-person trial found when it tested three of them.

How to read them
How do you get the most out of a guide?
-
Start with the question you actually have
Every guide leads with a short answer in plain language. Read that first; if it settles the question, you're done in 40 seconds.
-
Check the numbers against the claim
Study counts, sample sizes and dates sit in the stat strip and the tables. Where the evidence is thin, the article says so instead of dressing it up.
-
Bring it to your session
Tell us what you read and what you want from the visit. A 60 minute session aimed at one concern beats a generic one.
Our editorial standard
Why we publish these
Most spa blogs read like advertising. We would rather tell you what the evidence shows, because a head spa or a facial does not need overselling. The guides are sourced most often to the NCCIH's massage therapy overview, the American Academy of Dermatology's hair and scalp pages, Mayo Clinic's relaxation-technique guidance and the NIH's digest of what the science says about massage. When a study is small, we say so; when results are mixed, you will read that too.
Two caveats. None of this is medical advice: these are general-education articles, and your doctor knows your situation better than any web page. And we run a head spa, so read us the way you would read any business writing about its own field.
Before you dive in
Questions about these guides
How are these guides sourced?
Every claim traces to a named public source (NCCIH, Mayo Clinic, the American Academy of Dermatology, NINDS, AMTA or a published study) and each article lists its sources at the end. When a study is small or the results are mixed, the text says so.
Is this medical advice?
No. These are general-education articles, not diagnosis or treatment. For hair loss, a scalp condition, a recent injury or pregnancy, talk with your doctor or a board-certified dermatologist before booking.
Which guide should I read first?
New to head spas? Start with what a head spa is. Worried about thinning hair, read the scalp massage evidence review. If something hurts, start with the back pain or tension headache guide; if stress or sleep is the issue, start there.
Do I have to book at O2 to use these?
No. The guides are written to be useful wherever you go. If you are near Arcadia, a 60 minute head spa at 1432 S Baldwin Ave is $156, or $78 at the member rate, and we are open daily from 10 AM to 8 PM.
The practical half
Treatment and neighbourhood pages
The guides above are about the evidence. These pages are about the appointment: what each treatment costs at both rates, how long it runs, who it suits, and what the drive looks like from the next town over. Prices match our booking page, and every session runs at 1432 S Baldwin Ave, open daily from 10 AM to 8 PM.
