They can overlap, but the emphasis is different. Scalp treatment is usually results-focused — addressing specific concerns such as excess oil, persistent itch, flaking, sensitivity, scalp acne, or dryness. A head spa places greater emphasis on relaxation and the sensory experience, while still caring for the scalp. Some of our programmes, like Shiki — Signature Spa, combine both.

Dry scalp tends to produce fine, white flakes and is often accompanied by tightness or itchiness, with no excess oiliness. Dandruff (seborrhoeic dermatitis) typically produces larger, yellowish or oily-looking flakes and is often linked to scalp redness and a greasy root zone. A scalp analysis at the start of your NŌMI session will confirm which condition is present and which treatment approach is right for you.

In most cases, yes — though timing matters when the scalp is sensitised from a recent chemical service. We generally recommend waiting at least two to four weeks after a significant chemical treatment before a results-focused scalp session. If your scalp is already feeling irritated or reactive, let us know before booking.

This depends on the condition and its severity. For milder concerns, many guests notice a meaningful difference within two to three sessions. For persistent conditions — chronic dandruff, ongoing hair loss, or deeply sensitised scalps — a structured course of four to six sessions spaced two to four weeks apart is typically recommended, followed by monthly maintenance.
