Photobiomodulation is delivered by a particular device, not by the acronym PBM alone. Emitter type, spectrum, output, coverage, distance, pulse pattern, treatment geometry and device condition determine the exposure.
Laser and LED systems are not automatically interchangeable. No personal wavelength, energy, duration, frequency or dose protocol is created online.
Quick Orientation
Four questions before PBM or LED
The device and diagnosis define the treatment question.
A defensible discussion connects hardware identity, delivered exposure, scalp indication and a measurable review point.
02Exposure
Which light output?
Spectrum, irradiance, exposure time, geometry and pulse behaviour are considered as one system.
03Indication
Which diagnosis?
Pattern loss is separated from inflammatory, scarring, sudden and otherwise unexplained loss.
04Evidence
Which evidence?
The studied device, population, comparator, schedule and endpoint must resemble the proposed use.
Device Identity
Non-thermal intent · device-dependent exposure
PBM describes a biological approach, not one standard dose.
PBM devices aim to deliver low-intensity light without a thermal treatment effect, but actual exposure varies with hardware, output and use conditions.
What can be evaluated
- Identify a specific laser or LED device and its intended use
- Relate the full exposure and scalp coverage to one indication
- Use device-specific safety controls and eye precautions
- Document adherence, tolerability and a defined hair endpoint
What cannot be assumed
- Treat all red-light or low-level devices as equivalent
- Infer delivered dose from wavelength alone
- Replace diagnosis or established medical care
- Guarantee density, growth, maintenance or a universal schedule
A colour of light, emitter count or marketing power figure does not establish the exposure at the scalp or the clinical evidence for that device.
Medical Suitability
Diagnosis, device and light sensitivity
Five checks precede any PBM plan.
Online photographs cannot verify diagnosis, device output, scalp coverage, ocular protection or individual photosensitivity.
- 01
Confirm the diagnosis
A compatible pattern is separated from active inflammation, scarring, infection and unexplained shedding.
- 02
Examine scalp and hair
Coverage, hair length, scale, lesions and factors that may alter exposure are reviewed.
- 03
Review photosensitivity
Medicines, medical conditions, light-triggered symptoms and eye history are discussed.
- 04
Verify the device
Intended use, output specification, fit, integrity, maintenance and safety information are checked.
- 05
Define role and endpoint
Adjunctive use, established alternatives, adherence and objective follow-up are agreed.
Device and Exposure
Output · geometry · adherence
The delivered exposure is a system, not one number.
Device specification, output at the treatment plane, coverage, fit, eye safety, use conditions and adherence are documented together.
01Verification
Identify and inspect the device
The system, emitters, intended use, fit, output controls and current condition are confirmed.
- Record manufacturer and model
- Check coverage and maintenance
- Review eye and heat safeguards
02Exposure
Keep parameters connected
Spectrum, output, geometry, distance, pulse behaviour and exposure time jointly define what reaches the scalp.
- Avoid wavelength-only comparisons
- Account for hair and scalp coverage
- Use only the assessed device instructions
03Monitoring
Separate use from outcome
Adherence, tolerability and the later hair endpoint are recorded without changing several variables at once.
- Document actual use
- Record symptoms or device problems
- Compare the agreed endpoint consistently
A trial schedule or another manufacturer's instructions are not converted into a personal protocol for a different device.
Evidence and Limits
Sham-controlled trials · device heterogeneity
Evidence belongs to the tested hardware and population.
Randomised sham-controlled studies report signals for some devices in androgenetic alopecia. Differences in hardware, exposure, endpoints and study duration limit transfer.
Keep the device identity
A positive study does not validate every laser, LED, cap, comb or panel.
Keep the diagnosis narrow
Pattern-hair-loss data do not apply automatically to scarring or inflammatory alopecia.
Separate adjunct and monotherapy
Combined treatment cannot establish the independent contribution of light exposure.
Leave maintenance open
Long-term adherence, durability and comparison with medicines remain device- and study-specific.
Current evidence does not justify a universal device recommendation, a personal dose, superiority or a predictable response.
Individual Plan
Device, role and review point
A plan starts with one verified system.
Diagnosis, device status, expected burden, other treatments, safety and an objective endpoint determine whether PBM has a role.
Secure the baseline
Diagnosis, photographs, hair measure, current treatment and scalp findings are documented.
Verify the system
Device identity, fit, coverage, safety information, maintenance and intended use are checked.
Define its role
Adjunctive or stand-alone consideration is stated without promising a schedule or outcome.
Reassess the balance
Adherence, symptoms, objective findings, cost and alternatives determine continuation.
Course and Follow-Up
Tolerance, adherence and hair cycle
Device use and clinical response are measured separately.
Early comfort or warmth does not demonstrate effectiveness; hair endpoints require standardised documentation over an appropriate interval.
- 01Safety
First uses
Fit, comfort, eye protection, scalp sensation and device function are reviewed.
- 02Exposure
Ongoing use
Adherence, missed sessions, medication changes and device faults are documented.
- 03Outcome
Clinical review
Comparable photographs and the agreed measure are assessed without changing the endpoint.
- 04Plan
Continuation decision
Burden, tolerability, objective findings and alternative care are weighed again.
Risks and Alternatives
Eye safety · photosensitivity · device integrity
Low-intensity light still requires a safety framework.
Incorrect device use, ocular exposure, photosensitivity, heat, skin irritation, headache or delayed diagnosis are considered alongside product instructions.
01Exposure
Light and eyes
Eye history, protection requirements and unintended direct exposure are assessed for the specific device.
02Individual
Patient and medicine
Photosensitising medicines, light-triggered conditions, scalp disease and discomfort may alter suitability.
03Alternative
Other strategy
Authorised medication, observation, procedural care, transplantation planning or no device may fit better.
04Decision
Withhold or stop
Treatment is withheld or stopped when the indication, consent, safety controls or follow-up cannot support a proportionate plan.
Persistent symptoms, unexpected heat or a device fault lead to a product-specific clinical and technical review before further use.
Istanbul and Follow-Up
A device plan must work after travel
Availability, instruction and review need continuity.
International care considers whether the exact assessed device, safe use information and follow-up remain available after return.
01Before travel
Prepare the question
Hair-loss history, medicines, light sensitivity and any existing device details are organised.
02In Istanbul
Examine and verify
Diagnosis, scalp, device, safety, alternatives and a measurable role are reviewed.
03Planning
Document the system
If used, model, intended role, safety information and baseline are recorded.
04After return
Review at home
Actual use, symptoms and the objective endpoint follow an agreed contact and documentation route.
The Doctor Aslan Approach
Hardware before acronym
No wavelength or session plan is detached from the device.
Diagnosis, complete device identity, delivered exposure, safety and follow-up are considered together. PBM remains an option, not a guaranteed shortcut.
Name the hardware
Laser or LED, model, emitter layout and intended use are specified.
Keep exposure connected
Spectrum, output, geometry, coverage and time are not separated.
Match the evidence
Only studies of sufficiently similar devices and diagnoses inform the discussion.
Measure before continuing
Adherence, safety and an objective endpoint guide the next decision.
