What is a head spa? Every step, explained

A salon shampoo cleans the hair in a few minutes before a cut or color; this treatment spends most of an hour on the scalp underneath. That focus lines up with dermatologists' own advice. The American Academy of Dermatology (AAD) tells people to apply shampoo to the scalp instead of the entire length of the hair.

The massage is the other big difference: at the shampoo bowl it lasts a minute or two, if it happens at all, while here it is the main event and usually extends into the neck and shoulders. Massage is common and generally low risk: national survey data cited by NCCIH show 10.9 percent of U.S. adults used massage therapy in 2022, up from 4.8 percent in 2002, and NCCIH says the risk of harmful effects from massage appears to be low.

No. A dermatologist diagnoses and treats scalp and hair conditions; a head spa cleans and relaxes a healthy scalp. When someone comes in with hair loss, the AAD says dermatologists ask when it started, look closely at the scalp and nails, and test the hair with a gentle pull. They may add blood work or a scalp biopsy if they suspect a disease, deficiency, hormonal imbalance or infection. Treatment depends on the diagnosis, and the AAD states plainly that no one hair loss treatment works for everyone.

A head spa's scalp analysis is a cosmetic check of oil and buildup. It cannot tell thinning from shedding or spot an infection, and nobody at a spa should claim it can. Use each for its own job: the dermatologist for a diagnosis, the spa for a clean, comfortable scalp and an hour of massage.

Package D, the Classic Scalp Treatment, is O2's base session and runs 60 minutes. Most of it happens lying on a treatment bed with your head resting over a built-in basin, like the one in the room pictured at the top of this guide, and a folded towel over your eyes while the water runs. After the first few minutes there is nothing for you to do except say if the water feels too warm or the pressure too firm.

The booking page lists 8 parts to the session, and every longer package keeps them. Here is each part in plain terms; if you want to know the order on the day or how a step feels, ask your therapist before you lie back.

Each longer package keeps Package D and adds more massage and treatment time. Package C runs 75 minutes and adds a step the booking page calls "hair growth / strengthening nourishment", a hand, arms, neck, shoulder and head massage, a phototherapy meridian comb treatment, and high frequency ozone comb therapy.

Package B and Package A both run 90 minutes and build on Package C. Package B adds a hand, arms, neck, shoulder and head massage plus one add-on of your choice: a mini facial, a hand treatment or a neck treatment. Package A adds a back, arms, legs, neck, shoulder and head massage with hot stone therapy, which makes it the closest thing on the menu to a full massage with the scalp treatment attached.

Every package has two prices on the booking page, a regular rate and a member rate at half the regular price. The booking page doesn't explain how membership works, so ask the front desk before you book.

A head spa suits people who want a thorough scalp clean and a long, quiet massage in the same appointment. That includes people whose scalp feels oily or coated from dry shampoo and styling products, people who carry tension in the neck and shoulders, and anyone curious about the format who wants to start with the base session before trying a longer one.

Scalp condition matters more than hair type, because the work happens at the roots. Mention recent color, a sensitive or itchy scalp, or a fragrance you dislike when you book, so the therapist can adjust products and pressure.

Some situations call for waiting. Put off a booking if your scalp has open cuts, a fresh sunburn, an infection or a recent procedure your doctor hasn't cleared, and check with your doctor first if you have a condition that affects your skin or circulation.

For many people the calm is the main draw. Our guide to relaxation techniques between spa visits covers how to keep that state going at home.

A head spa cannot diagnose or treat hair loss, dandruff that won't clear, or any scalp condition. Some shedding is expected: the AAD says it's normal to shed between 50 and 100 hairs a day. Hair loss, by the AAD's definition, happens when something stops hair from growing, and the sooner treatment begins, the better the outlook. If your hair is noticeably thinner or coming out in large amounts, see a board-certified dermatologist before you book a spa.

Flaking deserves the same care. Mayo Clinic lists several causes of dandruff, including irritated oily skin, dry skin, sensitivity to hair care products and a fungus called malassezia that lives on the scalps of most adults, and notes that dandruff can get worse with stress and in cold, dry weather. A deep cleanse may lift visible flakes for a while, but the AAD's first step is a dandruff shampoo with an active ingredient such as zinc pyrithione, salicylic acid, selenium sulfide or ketoconazole, and some need to sit on the scalp for 5 to 10 minutes before rinsing. If regular use of a dandruff shampoo doesn't help, Mayo Clinic advises seeing your healthcare professional.

Treat Package C's "hair growth / strengthening nourishment" as the menu's name for a nourishing step rather than a regrowth claim. Our guide to scalp massage and hair growth walks through the small studies behind that idea and what they did and didn't show.

There is no medical schedule for this, so frequency comes down to your scalp, your budget and how much you enjoy it. A practical way to decide: book one session, notice how many days your scalp feels clean and light afterward, and book the next one when that feeling has gone. Some people come monthly; others save it for a stressful stretch or a special occasion.

Your daily routine does most of the work between visits. The AAD's advice is to match shampoo frequency to your hair: people with straight hair and an oily scalp may shampoo daily, while dry, textured or curly hair can go as long as every 2 to 3 weeks.

Preparing takes very little: book online or call O2 at (626) 857-6608, and leave enough time for the full session, from 60 to 90 minutes depending on the package. O2 is at 1432 S Baldwin Ave, Arcadia, CA 91007, open every day from 10 AM to 8 PM, a short drive from Temple City, Monrovia, Sierra Madre and Pasadena.
