Scalp detox in Arcadia: what the deep cleanse removes

Sebum, dead skin and product make up most of it. Sebum is the oil your scalp makes on its own, dead skin cells shed from the scalp surface all the time, and everything you put on your hair, from dry shampoo and styling cream to leave-in oil and hairspray, settles at the roots. Sweat adds to the mix. Mayo Clinic lists irritated, oily skin and malassezia, a yeast that lives on the scalps of most adults and feeds on natural oils, among the causes of dandruff, which helps explain why oil and flakes so often turn up together.

Anyone can collect buildup, but three groups tend to notice the difference after a deep cleanse most clearly.

Dry shampoo soaks up oil and leaves a fine powder behind, and a quick wash at home does not always reach all of it at the roots. Add styling cream or spray over several days and the scalp can feel coated even straight after shampooing. A slower cleanse with steam and a long rinse gives that residue more time to loosen.

The more hair there is, the harder it is to get shampoo onto the scalp rather than the lengths, so residue can sit at the roots without being obvious. A cleanse done by someone else, with both hands free and a waterfall rinse running overhead, is likely to reach the scalp more evenly than most people manage in their own shower.

A cap, a bike or motorcycle helmet, or a daily workout keeps heat and sweat against the scalp for hours at a time. If you wear a helmet to work or train most days, your scalp may feel heavier by evening, and a deep cleanse is likely to feel like a bigger change for you than for someone who washes daily and uses little product.

It clears the oil for now, but it will not change how much oil your scalp makes. Your own glands set that, so an oily scalp will look oily again within a day or so of any wash, at home or at a spa. What a deep cleanse can do is reset the starting point, taking off older oil mixed with product that an everyday shampoo may leave behind.

Day to day, the AAD's tips for healthy hair are the more useful tool. For straight hair and an oily scalp, it suggests you may want to shampoo every day. It also advises putting shampoo on the scalp rather than along the whole length of the hair, and, for fine or straight hair, keeping conditioner to the ends.

If the oil comes with flakes, redness or itching, read the next section before booking anything, because that combination can point to dandruff rather than plain oiliness.

Look at the flakes and at what clears them. Buildup feels waxy or gritty at the roots and comes away with a thorough wash. A dry scalp tends to shed small, dry flakes and feel tight, often in cold weather. Dandruff shows up as flakes on the scalp, hair, eyebrows or shoulders, often with an itchy scalp, and Mayo Clinic notes that it can get worse with stress and in cold, dry weather.

When flakes keep coming back between washes, the AAD starts with a dandruff shampoo rather than any salon treatment. Look for one of six active ingredients: zinc pyrithione, salicylic acid, sulfur, selenium sulfide, ketoconazole or coal tar. Some are meant to be left on for 5 to 10 minutes before you rinse them out. With straight or oily hair the AAD suggests using it twice a week, and with coarse, curly or coily hair about once a week.

See a board-certified dermatologist if the flakes have not cleared after you follow that advice, if they become severe, or if the scalp is red, sore, crusted or spreading past the hairline. Mayo Clinic gives the same advice for dandruff that does not improve with regular use of a dandruff shampoo. A deep cleanse may wash flakes away for a few days, but it does not treat what is causing them.

Package D runs 60 minutes, and every step on its list either cleans the scalp or massages the head and upper body. If buildup is the reason you are booking, the scalp analysis matters most: it is done at the start and again at the end, so you can compare the roots before and after the cleanse.

The cleansing work comes from three steps: deep scalp cleansing, nano steam, and waterfall hydrotherapy, a steady flow of warm water from an arch over the basin. A scalp serum spray and a high frequency ozone comb also work on the scalp, and the aromatherapy oil massage and the head, neck, shoulder and arms massage take up the rest of the hour.

You do not need to wash your hair specially the night before. The first analysis is most useful when it shows your scalp as it usually looks, buildup included; if you are unsure what O2 prefers, ask when you book. The booking page lists the steps like this:

A scalp detox in Arcadia at O2 costs $156 at the regular rate or $78 at the member rate, for the 60 minute Package D. The booking page lists both prices for every session; ask the front desk how membership works. If you also want the menu's hair growth / strengthening nourishment step and a phototherapy meridian comb, Package C adds them in 75 minutes for $176 regular or $88 member, and our page on a head spa for hair loss explains what those extra steps can and cannot do.

If tight shoulders are part of why you want the hour, Package B runs 90 minutes for $196 regular or $98 member. It keeps every Package C step and adds a longer hand, arms, neck, shoulder and head massage plus one add-on: a mini facial, hand treatment or neck treatment.

No fixed schedule suits everyone. Notice how many days your scalp feels clean after the first visit, then book again when the coated feeling returns. Someone who uses dry shampoo most days or wears a helmet to work may notice it sooner than someone who washes daily with little product. Between visits, your own routine does most of the work.

Buildup comes back through everyday habits, so small changes at home stretch the time between deep cleanses. These are the ones most likely to help:
