Five Conditions of Scalp Fixed-Point Photography to Avoid ‘I Can’t Tell the Change from Photos’ — Dr. Moriwaki Organizes a Self-Photography Method to Objectively Record Progress in Stem Cell Conditioned Media Hair Regenerative Medicine2026.07.24

‘It’s been several months since I started treatment, but when I take photos myself and compare them, honestly I can’t tell whether my hair has increased or stayed the same.’ This is a complaint we hear very often in the outpatient clinic. This is not because treatment is ineffective; in most cases, the cause is simply that the conditions of scalp fixed-point photography are not aligned. If the color of light differs, the head angle differs, or the parting differs from the previous shot, the impression of thinning at the crown or M-shaped recession can change dramatically. Because stem cell conditioned media hair regenerative medicine is a treatment where changes accumulate gradually in 3-to-6-month units, ‘whether you keep shooting under the same conditions’ directly determines the quality of progress assessment. In this article, Dr. Moriwaki organizes, from a clinical perspective, the five conditions of scalp fixed-point photography that we actually ask patients to follow at AVAN TOKYO Ginza.

Key Points of This Article

・The purpose of scalp fixed-point photography is ‘to repeat under the same conditions,’ not to take beautiful photos

・Just by aligning the five conditions of light source, camera distance, head angle, hair state, and shooting interval, the accuracy of progress assessment improves significantly

・Because stem cell conditioned media hair treatment shows changes mainly in 3-to-6-month units, shooting once a month on the same weekday and time is practical

・Do not judge by scalp fixed-point photography alone; combining it with microscope observation and physician examination allows separating ‘just my imagination’ from ‘real change’

・Even when little change is visible, the very fact of ‘not having worsened’ can itself be an outcome of treatment

Why Progress in Hair Treatment ‘Cannot Be Judged Even by Comparing Photos’

Hair Style, Light, and Angle Change the Appearance Surprisingly Much

When shooting the crown with a smartphone, a photo illuminated by direct white LED and one illuminated by daylight through a window give very different impressions of scalp visibility. Light with high color temperature has a blueish cast and emphasizes the pink of the scalp, while warm-toned light weakens the contrast between hair and scalp, working in the direction of ‘looking denser.’ Tilting the head by just 10 degrees changes how hairs from the crown whorl overlap and shifts the width of scalp visibility. The same happens by shifting the parting by just 1 cm. In other words, comparing photos taken without aligning conditions is not comparing treatment effect but comparing differences in shooting conditions. The scary thing about photos is that with the same scalp, depending on conditions, both ‘more’ and ‘less’ conclusions can be produced.

‘Memory Correction’ Rewrites Your Own Memory

Another pitfall is the fact that the patient does not accurately remember the state from three months ago. Because people look at their own head in the mirror every day, subtle changes are hard to recognize; conversely, expectations and anxieties such as ‘I started treatment, so I want it to be better’ or ‘I’ve been going all this time — could it not be working?’ act as filters and rewrite memory. That is precisely why an objective record — scalp fixed-point photography under fixed conditions — is necessary rather than relying on feelings.

Five Conditions of Scalp Fixed-Point Photography — To Reproduce the Same Conditions

1. Fix the Light Source

Light has the greatest impact. Ideally, shoot under ‘the same lighting each time’ in the bathroom or living room without using the flash. Natural light from a window changes both color temperature and brightness with the time of day and weather, so it is actually a low-reproducibility light source. Since the smartphone’s auto white balance cancels out the color of the light, if possible use ‘auto correction off’ in the camera app or avoid applying corrections after shooting. Because the flash also changes reflection position every time, avoiding it in principle preserves the fixed-point quality better.

2. Fix the Camera Position and Distance

When shooting the crown, decide on a ‘same distance every time,’ such as asking a family member to shoot from 30 cm directly above, or shooting from the same position via the bathroom mirror. When the distance changes, the head’s share within the frame changes, altering the impression of scalp visibility. Even without a tripod, tricks like marking the mirror or taping a standing position on the floor are enough to reproduce the position effectively.

3. Fix the Head Angle

Decide on the same posture every time, such as ‘standing straight with gaze horizontal, shot from directly above.’ Leaning forward causes the crown’s hair flow to fall forward, making the scalp more visible; leaning backward hides it. Just a few degrees change the impression, so avoid tilting-head shots and routinize the posture itself.

4. Standardize the Hair Condition

Each time, follow rules such as shooting after natural drying following a wash, no blow dryer, and no styling product. Comparing a crown given volume by styling product with a crown left flat after a wash reveals not treatment effect but styling difference. On days when hair was colored or permed the day before, since color and hair flow have changed, it is better to postpone shooting.

5. Decide the Shooting Interval and Number of Shots in Advance

Due to the hair cycle, stem cell conditioned media hair treatment shows changes in 3-to-6-month units. Therefore we recommend fixing shooting to once a month, on the same weekday and time, with the same elapsed time since washing — and taking five shots per session (crown, whorl, frontal hairline, and left and right temporal regions). Without deciding the shot composition in advance, only the region that catches your attention will vary, making progress comparison impossible.

Connecting Scalp Fixed-Point Photography Results to ‘Treatment Decisions’

Not Seeing Change Does Not Necessarily Mean It Is Not Working

AGA and female diffuse thinning are inherently ‘progressive’ conditions. Even if scalp fixed-point photography shows no visible increase after three months, the very fact of ‘not having worsened compared to the same time last year’ can be a sign that treatment is maintaining the follicular environment. Stopping worsening is one meaningful outcome in hair regenerative medicine. Especially for patients who have entered the maintenance phase, the question is often not ‘increase or no decrease’ but ‘no decrease, or slowing of progression.’

Combine with Microscope and Physician Examination

Scalp fixed-point photography is a tool to track changes in ‘overall appearance.’ On the other hand, micro-level changes such as the number of hairs per follicular unit or variation in hair diameter cannot be captured by naked-eye photos; only by combining microscope observation with the physician’s palpation and inspection does the whole picture emerge. At our clinic, we combine patients’ self-photography with in-clinic scope observation by the physician for progress assessment.

For general diagnostic and treatment guidelines on alopecia, information published by the Japanese Dermatological Association is also helpful.

Frequently Asked Questions

Q. Is a smartphone enough for scalp fixed-point photography, or do I need special equipment?

A smartphone is sufficient. However, since changing devices changes the angle of view and white balance tendencies, we recommend shooting with the same device as much as possible during the course. A dedicated microscope is useful for evaluating the number of hairs per follicular unit, but recording the ‘overall fixed point’ with a smartphone is the top priority first.

Q. Should I take photos every day?

Daily photos are unnecessary. Because of the hair cycle, changes over a few days are mostly noise, and comparing too finely leads to emotional ups and downs. Once a month, on the same weekday and time, is enough to follow the treatment course.

Q. Is it OK to shoot the hairline from the front and the crown from directly above?

Yes, that combination is fine. However, shooting the hairline from below emphasizes vellus hairs and makes it look ‘increased,’ while shooting from above emphasizes recession. Please fix shooting from the front, horizontally.

Q. When scalp fixed-point photography shows little clear change, should I continue treatment?

The decision is not made by photography alone. The physician evaluates microscope findings, hair diameter, hair density, and general condition to comprehensively assess progression and treatment response before deciding on continuation, addition, or reconsideration. Sometimes 3 to 4 months is too early to judge.

Q. Do I need to show the photos to the physician every visit?

Sharing them at each visit improves the accuracy of progress assessment because they can be compared with in-clinic findings. Just preparing one folder organized by shooting date is enough.
