Head spa is a wellness service, not a medical treatment. This distinction is fundamental—and it places a concrete responsibility on each practitioner: knowing how to identify situations in which a session is not recommended, needs to be adapted, or simply postponed.
Knowing the situations that require postponing or adapting a Japanese head spa session is not an administrative precaution. It is a professional skill. It is what allows you to treat each client with discernment, maintain a high standard of care, and operate in a more secure professional setting.
This guide lists situations requiring a session to be postponed or adapted, and how to conduct an effective preliminary interview before each treatment.
Situations requiring session postponement
Certain situations dictate that the treatment should not be performed, regardless of the client's request. These are not rare cases—they occur regularly in salons, and identifying them upon arrival is a key skill.
| Situation | Reason | Action to take |
|---|---|---|
| Open wounds or active scalp lesions | Risk of infection, pain, aggravation | Decline—postpone until complete healing |
| Suspicion of infectious or contagious scalp condition: unusual patches, scabs, pustules, or unexplained lesions | Risk of contagion and worsening condition | Postpone the session and recommend medical advice, without attempting to identify the pathology |
| Psoriasis or eczema with active lesions, weeping, or painful areas | Risk of irritation and worsening of lesions | Postpone the session—the practitioner should not attempt to assess the stability of the pathology alone |
| Active lice or nits | Risk of contamination of equipment and other clients | Decline—postpone until complete treatment |
| Recent cervical or cranial surgery | Risk related to manipulations and lying position | Decline—medical advice essential before resuming |
| Known allergy to products used in session | Risk of allergic reaction | Adapt products or decline if substitution is not possible |
Situations allowing for comfort adaptation
Other situations do not warrant postponement but require protocol adaptation. This is where the practitioner's expertise makes a difference: not applying a standard protocol, but adjusting based on what they observe and what the client tells them.
| Situation | Recommended adaptation |
|---|---|
| Very sensitive or reactive scalp | Reduced pressure, fragrance-free and alcohol-free products, lukewarm water (not hot) |
| Pregnancy | Avoid essential oils as a precaution, adapt position, reduce duration if uncomfortable, check recommendations from healthcare professional |
| Cervicalgia or chronic neck pain | Adjusted headrest, position checked before session begins, lightened neck massage pressure |
| Known psoriasis or eczema, not during a flare-up | Check for absence of active lesions and recommendations from the client's healthcare professional. If in doubt, postpone the session. |
| Ongoing medicated scalp treatment | Ask the client for their doctor's consent, adapt products used |
Recent coloring: a technical precaution
After coloring, the scalp may be temporarily more sensitive and some products used during the treatment may affect color retention. It is preferable to wait 48 hours as a precaution, or to check the color manufacturer's recommendations. If the client wishes to have a session within this period, clearly inform them of the potential risk to their hair color before starting.
The preliminary interview: how to conduct it
An effective preliminary interview takes no more than five minutes. It is done before the client is seated at the shampoo bowl, and it covers three levels.
Visual observation
Before any contact: observe the condition of the scalp with the naked eye. Redness, flakes, visible lesions, areas of apparent sensitivity. This initial look already guides the protocol—or leads to postponing the session and recommending medical advice if a visible anomaly is noted.
Preliminary questions
A brief exchange allows for covering the main factors likely to lead to postponing or adapting the session. In case of doubt about a reported situation, the practitioner does not try to assess it themselves—they postpone and refer to a healthcare professional.
- Do you have a history of scalp sensitivity or allergies to hair products?
- Do you have neck pain or difficulty lying down?
- Are you pregnant or undergoing medical treatment involving the scalp?
- Have you had your hair colored or chemically treated in the last 48 hours?
- Do you have any visible lesions, itching, or anomalies on your scalp at the moment?
These questions are asked naturally, without a medical protocol. They are a sign of professionalism that clients perceive positively.
Checking for comfort and sensitivities
A very light touch allows to verify with the client the areas they report as sensitive or uncomfortable. In the presence of unexplained pain, a visible anomaly, or doubt, the session should be postponed and medical advice recommended. This gesture of attention is part of the care—it is not a formality.
What head spa does not address
An important clarification, which protects both the client and the practitioner: head spa is a wellness treatment. It is not intended to treat, correct, or cure a hair or dermatological pathology.
Any communication implying that a Japanese head spa session treats hair loss, stimulates regrowth, cures psoriasis, or acts on an identified pathology is a therapeutic claim—it carries a legal risk and falls outside the legal framework of a wellness activity.
When a client presents a concern that goes beyond wellness (significant and sudden hair loss, unexplained lesions, persistent pain), the correct approach is to refer them to a dermatologist or doctor, without attempting to address their request through the treatment.
This is a clear limit—and fully embracing it strengthens professional credibility, rather than diminishes it.
Equipment hygiene: a non-negotiable point
Contraindications concern the client—but the management of professional head spa equipment is a permanent responsibility of the practitioner, regardless of the condition of each client's scalp.
Systematic vigilance points after each session, according to manufacturer instructions and the establishment's hygiene protocol:
- Complete rinsing of the shampoo bowl and water circuits (connected bowls) or emptying and cleaning of the reservoir (standalone bowls)
- Disinfection of surfaces in contact with the scalp and neck
- Washing or replacement of towels and textile accessories
- Cleaning of nozzles and misting system if additional equipment is used
- Checking for absence of product residues in the drains
A documented hygiene protocol is also a professional argument. Check with your insurer for the hygiene and traceability procedures expected under your professional liability contract.

FAQ — Head Spa Contraindications
Can a head spa be performed on a pregnant client?
Pregnancy does not systematically prohibit a head spa session, but it requires checking the client's comfort, the products used, and any recommendations from their healthcare professional. Essential oils should be avoided as a precaution. Adapting the position at the shampoo bowl, reducing the duration if the client reports discomfort, and avoiding any intense heat source are basic adjustments.
In case of a high-risk pregnancy, complications, or the slightest doubt, the session must be postponed until medical advice is obtained. The preliminary interview is simply more attentive, and the protocol is lightened accordingly.
How to manage a client with scalp psoriasis?
In the presence of active lesions, significant redness, weeping, bleeding, or painful areas, the session must be postponed. The practitioner must not attempt to determine themselves if the psoriasis is stable enough to receive treatment. Outside of flare-ups, the client must check with their dermatologist that the planned protocol is compatible with their situation and any ongoing treatment.
It is important never to promise the client that the treatment will improve their psoriasis—that is a therapeutic claim. The correct statement is: "I can adapt the treatment to ensure your comfort, avoiding sensitive areas, if your dermatologist approves the session."
What to do if a client has a reaction during a session?
Immediately stop the session and cease using the product concerned. Rinse the scalp thoroughly with clean water according to the manufacturer's instructions. In case of simple localized discomfort, advise the client to consult a doctor if symptoms persist or worsen. In the presence of significant swelling, breathing difficulties, malaise, or a generalized reaction, immediately call 911 (or your local emergency number) and follow the emergency services' instructions.
In all cases: keep a factual record of the incident and the products used, in accordance with applicable personal data protection rules and your insurer's requirements. Check with your professional liability insurer for any reporting obligations stipulated in your contract.
Is a written questionnaire required before each head spa session?
A preliminary exchange is highly recommended before each session. If you choose to collect and keep written information regarding your clients' allergies, treatments, or pathologies, be aware that this data may fall under the category of health data: collect only what is strictly necessary, inform the client of how this information will be used, and ensure its secure storage.
A signed questionnaire improves traceability but does not replace professional precautions or the obligations stipulated in your insurance contract. Check with your professional liability insurer for documentation requirements.
Is head spa contraindicated after coloring?
Recent coloring is not a health situation comparable to a wound or infection—it is a technical and commercial precaution. After coloring, the scalp may be temporarily more sensitive, and some products used during the treatment may affect color retention. It is preferable to wait 48 hours as a precaution, or to check the color manufacturer's recommendations.
If the client comes within this period and wishes to have a session, clearly inform them of the potential risk to their hair color and let them make the decision. If you adapt the treatment (lukewarm water, no friction, gentle products), note it in their file to avoid any later claims.
