Your scalp hasn't been truly clean in months. Here's what to do about it.

Most of us wash our hair every other day and assume that's the same as a clean scalp. It isn't. Shampoo rinses the surface — it doesn't touch the layer of dead skin, product residue and sebum that builds up at the root over weeks, quietly clogging the follicles it's sitting on top of.

What's actually happening under the surface

Your scalp is skin, and it behaves like skin everywhere else on your body — it accumulates buildup, it reacts to pollution and stress, and it needs more than a rinse to actually reset. If any of this sounds familiar, buildup is usually the reason:

• An itchy, flaky or oily scalp that never quite settles, no matter what shampoo you switch to
• Hair that feels weighed down or lifeless at the roots by evening
• Noticeably more hair in the shower drain than you remember
• Tension headaches or a tight, tired feeling across your scalp and neck

Chronic tension is part of this too. Most of us carry stress physically in the scalp and neck without noticing — and a tight scalp restricts the circulation that healthy hair actually depends on.

What a proper scalp reset actually involves

A Korean Head Spa isn't a fancier hair wash. It's a full diagnostic-and-treatment ritual, and at Plum & Sugar it runs in four parts:

• Scalp analysis — a close, sometimes magnified look at your actual scalp condition before anything else happens, so the ritual is built around what your scalp needs, not a generic routine
• A deep, detoxifying cleanse that lifts buildup, oil and pollution that everyday shampoo leaves behind
• A custom mask matched to your specific concern — oily, dry, flaky or simply stressed
• A cervical, neck and shoulder massage to close the ritual — this is usually the part people say they needed most

"I came for hair and left feeling like a completely different person. This ritual is life-changing."

How often, and what it can (and can't) fix

A healthy, clean scalp is the foundation healthy hair grows from, and clients often notice less oiliness and a calmer scalp within a couple of sessions. It's worth being honest about what this is, though: it's supportive scalp care, not a medical hair-loss treatment — if you're dealing with a diagnosed condition, this sits alongside a dermatologist's advice, not instead of it.

For everyday buildup and stress, monthly is the sweet spot — enough to keep your scalp genuinely clean rather than just recently rinsed, and enough to make it a real, protected hour of calm in your month.
