A Bojin hair session should not feel like a mystery. Before booking, you should understand what will touch your scalp, what the appointment includes, how to communicate discomfort and what you can realistically expect afterwards.
Retern describes Bojin as a tool-assisted approach influenced by traditional Chinese meridian principles. Its published service explanation includes scalp observation, cleansing, product application, massage movements and finishing care.
Those details explain an experience. They do not, by themselves, prove that the treatment reverses a particular hair-loss condition.
This guide covers seven practical questions to help you approach a Bojin hair session with clear expectations—from preparation to aftercare and progress reviews.
1. What exactly are you booking?
Start by asking what the quoted appointment includes.
Retern’s Bojin Hair Growth Therapy overview describes a smooth, rounded instrument used for massage movements involving the scalp, neck and shoulders. However, the precise products, treatment areas and additional steps should be confirmed for your booking.
Ask about:
- Total appointment time, including consultation and finishing
- Which treatment areas are included
- Products that will be applied
- Whether cleansing and drying are included
- Any optional additions and their prices
- Whether the quotation covers one visit or a package
Do not assume that LED, steam, a particular serum or another add-on is automatically included.
A clear explanation before your Bojin hair session helps you decide whether the experience suits your needs and budget.
2. What should you tell the consultant beforehand?
Describe your main concern in ordinary language. “My crown becomes greasy by evening” or “My scalp burns after colouring” is more useful than trying to assign yourself a diagnosis.
Explain when the problem began and whether you have noticed flakes, bumps, pain, shedding or changes in density. Mention relevant allergies, scalp conditions, recent colouring, hair extensions and recent procedures.
Also disclose medicines or health conditions that could affect suitability, including blood-thinning treatment or a tendency to bruise. Do not stop prescribed medication to attend a cosmetic appointment.
Ask whether you should wash your hair beforehand. There is no need to deliberately arrive with several days of oil or product buildup to make an assessment look more convincing.
For a first Bojin hair session, a photograph of your regular shampoo and leave-on products may help explain your current routine.
If there is broken skin, an active rash, painful pustules or unexplained patchy loss, seek medical advice before proceeding with massage. Scalp folliculitis, for example, can cause sore, crusted lesions that need appropriate assessment. DermNet scalp folliculitis
3. What can the initial scalp observation tell you?
Magnification can make visible flakes, surface residue, redness and differences in hair appearance easier to discuss.
It cannot identify a vitamin deficiency, confirm a hormonal cause or prove that follicles are “blocked” and unable to grow hair. The interpretation also depends on when you last washed, whether your hair is wet and which products are present.
Retern’s scalp-camera analysis guide explains these limits.
Before a Bojin hair session begins, ask what the consultant actually observes and which conclusions remain uncertain. A useful explanation should distinguish visible findings from possible causes.
If the findings suggest a medical condition, the next step may be a doctor’s assessment rather than a larger treatment package. You should also be able to ask questions and decline an optional step without pressure.
4. What happens during the treatment itself?
The published Retern outline describes cleansing, applying a product to support the treatment, tool-assisted movements and finishing products. Confirm the current sequence with the team, because products and individual arrangements may differ.
During your Bojin hair session, the practitioner should explain the areas being treated and check that the pressure is comfortable. You can ask to avoid a sensitive spot or stop a movement that catches your hair.
Practical questions include:
- What product is being applied, and does it contain an ingredient I react to?
- Will this step involve my neck or shoulders?
- Can the pressure be reduced?
- Is the product intended to remain on the scalp afterwards?
Traditional explanations involving meridians describe the approach’s background. They should not be presented as a medical diagnosis of the cause of your hair loss.
You do not need to accept language about “toxins” or “dormant follicles” without asking what is being measured and what evidence supports the claim.
5. What should it feel like—and when should you speak up?
Pressure and movement will vary with the technique and your sensitivity. The aim should be a tolerable experience, not an endurance test.
Tell the practitioner immediately if you experience sharp pain, burning, strong pulling, dizziness or increasing discomfort. Do not wait until the end because you assume pain means the treatment is working.
Warmth or tingling during a Bojin hair session is not a measurement of new growth. Likewise, redness and bruising are not proof that harmful substances have been released.
You remain in control of the appointment. Asking for lighter pressure, avoiding an area or ending a step is reasonable.
If symptoms continue after treatment or you develop swelling, a rash or painful bumps, contact the provider and obtain medical advice as appropriate. Severe allergic symptoms, including breathing difficulty or throat swelling, require emergency care.
6. What should you do immediately afterwards?
Before leaving, ask for aftercare instructions tied to the products actually used.
There is no reason to invent a universal rule such as “never wash for 24 hours” unless the provider can explain why it applies to the specific formulation. Ask whether anything needs rinsing out and when your usual routine can resume.
Keep the rest of the day’s routine uncomplicated. Avoid immediately adding a scalp scrub, concentrated essential oils or several unfamiliar serums.
If you use a prescribed scalp medicine or topical hair-loss treatment, ask the prescribing clinician how it should fit around the appointment. Do not skip or change treatment based on an unsupported claim that massage improves absorption.
After a Bojin hair session, you may notice differences in cleanliness, styling or comfort. These are worth describing accurately, but they are not the same as an increase in hair density.
Record any irritation as well as any benefit. A useful review includes both.
7. How should you judge results over time?
Decide which outcome matters before committing to repeated visits.
For scalp comfort, you might record itch, tenderness or how long the scalp feels comfortable after washing. For hair density, use comparable photographs and consider medical assessment when thinning is progressive.
Keep lighting, angle, parting and hair condition consistent. A freshly styled photograph cannot be fairly compared with a wet, heavily parted “before” image.
A small study of standardised mechanical scalp massage involved nine healthy men. It reported increased hair thickness, but not a significant improvement in growth rate. It was not a trial of Retern’s Bojin programme and cannot establish that the service treats hair loss. Original massage study
A pleasant Bojin hair session can be valued as an experience without turning that satisfaction into an unsupported regrowth claim.
If a package is recommended, ask what will be reviewed, when the review happens and what would prompt a change in approach. There is no evidence-based universal number of Bojin sessions that guarantees regrowth.
What can a Bojin hair session realistically offer?
The most useful distinction is between the appointment’s components and the medical cause of thinning.
Cleansing can remove surface material. Massage provides physical contact that some people find relaxing. Finishing care can change how hair feels and looks.
Whether hair loss improves depends on its cause and the suitability of the treatment. Pattern hair loss, temporary shedding, alopecia areata and inflammatory scalp disease do not all respond to the same approach. American Academy of Dermatology hair-loss guidance
A Bojin hair session should therefore sit within an informed care plan—not replace a diagnosis when symptoms require one.
A simple checklist before you book
You should be able to answer these questions:
- Do I understand the steps and total price?
- Have I disclosed allergies, relevant medicines and recent procedures?
- Have any painful or inflamed areas been addressed?
- Do I know how to request lighter pressure or stop?
- Will I receive product-specific aftercare?
- Are the promised outcomes realistic?
- Is there a clear review point before buying more sessions?
A confident booking comes from clear information, not a guarantee that everyone will achieve the same result.
Frequently asked questions
Is a Bojin hair session supposed to hurt?
You should not be expected to tolerate sharp pain, burning or significant pulling. Speak up immediately so the technique can be adjusted or stopped.
Should I wash my hair before attending?
Confirm this with Retern when booking. Preparation depends on the appointment and assessment arrangements. Do not deliberately create buildup beforehand.
Will the treatment include oils?
Confirm the exact formulation with the team. Retern’s public descriptions differ, so an older article should not be treated as a guarantee of the product used at your appointment.
Can I return to my normal routine afterwards?
Ask for instructions based on the actual products and steps used. There is no universal washing restriction that applies to every Bojin hair session.
How many sessions will I need for hair growth?
A fixed number cannot be responsibly promised. First establish the cause of thinning and whether the proposed approach is appropriate. Review comfort and cosmetic changes separately from d
