How to Design Hairline Position? Glabella Ratio and Common Myths
Many people assume that for a hair transplant, a lower hairline always looks better. In practice, position should follow facial proportion — not “the lower, the prettier.”
Dr. Wen-Yi Wu notes that measuring upward from the glabella (between the brows), roughly 7 to 8 cm is a commonly suitable height. That is a reference range, still adjusted for face shape, temples, and future loss trends after an individual medical assessment.
Key takeaways: Hairline design is about proportion, not going as low as possible. About 7–8 cm above the glabella is a common reference; actual height also depends on face shape, temple turns, and donor conditions, and should be set only after a professional doctor’s in-person assessment.
Why Isn’t a Lower Hairline Always Better?
A common clinic myth equates “a lower hairline” with looking younger and better.
If the position is too low, the forehead can look short and facial proportions unbalanced; with frontalis movement and facial expression habits, an overly low design can also look unnatural.
So the goal is not to plant as far down as possible, but to keep hairline height, temple transitions, and overall face shape in balance.
What Does 7 to 8 cm From the Glabella Mean?
A simple reference doctors often use is measuring vertically from the glabella up to the planned hairline.
For many people, about 7 to 8 cm is a frequently used reference range from facial-proportion observation — not a single number everyone must hit.
Assessment also considers forehead width, face length, the original hairline pattern, and whether M-shaped recession is already present. The number is a starting point, not the only standard.
If you are comparing overall male hairline transplant planning, see male hairline transplant: design and recovery; for how far a female hairline can be lowered, see female hairline lowering limits, so different search intents stay separate.
What Else Should Design Consider Together?
Besides central height, whether temple (temporal) turns are soft and whether both sides are symmetric strongly affects how natural the result looks.
Donor supply, native density, and how far male-pattern recession may continue also matter. Pulling the line very low for today’s look can make the border more obvious if native hair keeps thinning later.
One plan often covers: how far to restore now, where to leave buffer, and whether medication is needed to stabilize loss.

| Assessment focus | Why it matters | Common clinic approach |
|---|---|---|
| Central height (from glabella) | Sets forehead length and first-glance proportion | Use ~7–8 cm as a reference, then fine-tune by face shape |
| Temple / temporal turn | Affects side profile and naturalness | Check curve; avoid overly sharp or forced downward turns |
| Future loss space | Avoids a harsher border later | Leave buffer; discuss medication and staging |
| Donor and density | Limits how dense and how far you can go | Assess occipital donor and native hair |
How Do Male and Female Hairline Designs Differ?
Men more often need M-shaped recession and temple gaps addressed, with design stressing continuity to native hair flow and room for possible further recession.
Women more often discuss a high forehead or central/side asymmetry; how far the line can drop also depends on frontalis activity, planting area, and donor supply — one fixed centimetre rule does not fit everyone.

| Situation | Common focus | Design reminder |
|---|---|---|
| Male M-shaped recession | Temple fill, blend with native hair | Avoid too low; reserve future change |
| Female high forehead / recession | Lowering range, frontalis, symmetry | Don’t force a fixed cm; use overall proportion |
| Side asymmetry | Left–right temple height difference | Fine-tune using the more balanced side as reference |
Dr. Wu’s Own Explanation
Many people think a lower hairline always looks better, but position should follow proportion.
Measuring up from the glabella, an average around seven to eight centimetres is often more suitable.
Of course every face differs, and the final plan still needs an in-person assessment.
Dr. Wu has also explained this proportion idea in a short video — you can watch it below:

Must the hairline be placed at exactly 7 to 8 cm? +
No fixed rule. 7 to 8 cm is a common reference range; the final height still depends on face shape, temples, native hair, and future loss trends, decided after a doctor's assessment.
Will a lower hairline always look younger? +
Not necessarily. Too low can shorten the forehead, unbalance proportions, or look unnatural. A natural youthful look usually comes from suitable proportions and temple transitions, not from going as low as possible.
Are the temples really that important when designing a hairline? +
Yes. Central height drives first-glance proportion; temple transitions shape the side profile and overall naturalness. Reviewing both together usually looks more balanced.
If I already have an M-shaped recession, can the hairline still be lowered? +
It can be discussed, but donor supply and future recession space must be assessed together. Sometimes temples and frontal gaps are improved first rather than pulling the line very low in one step; suitability needs an in-person assessment.
Is hairline design the same for women and men? +
Not entirely. Men more often need M-shaped and temple work; women more often discuss a high forehead and how far it can be lowered. Assessment items overlap, but aesthetic goals and limits often differ.
Can photos alone decide hairline position? +
Online photos support a first discussion only and cannot replace an in-person exam. Final placement still needs scalp, hair direction, donor zone, and facial dynamics — book a doctor's assessment.
