Follicle, graft and follicular unit: not the same thing
The most common confusion in hair transplant quotes is vocabulary. The unit that is transplanted is the follicular unit (the "graft"): a natural grouping containing 1 to 4 hairs.
So 2,000 grafts are not 2,000 hairs: they are, on average, 4,000 to 5,000 hairs. When comparing quotes or reading figures online, always check whether they mean grafts or hairs — some clinics advertise "follicles" while counting individual hairs to make the number sound bigger.
Orientative ranges per zone
With the caveat that no serious figure is given without examining your scalp, these are the usual orders of magnitude in international practice:
- Temples / moderate frontal recession: on the order of 800 to 1,500 grafts.
- Full frontal hairline and first third: on the order of 1,500 to 2,500 grafts.
- Crown: on the order of 800 to 1,500 grafts, depending on the whorl’s diameter.
- Advanced hair loss (frontal + mid + crown): 2,500 to 4,000+ grafts, sometimes split across more than one session.
- Beard, mustache or eyebrows: smaller areas with their own requirements — see beard & mustache transplant.
The Norwood scale: the map that structures the conversation
Surgeons classify male androgenetic alopecia with the Norwood scale (I to VII). It is not academic vanity: each grade implies a different surface to cover and therefore a different graft range. A Norwood III needs a fraction of what a Norwood VI needs.
But the scale is the start, not the end: two patients with the same Norwood grade can need very different numbers depending on hair caliber (thicker hair covers more), the contrast between hair and skin color, and the density being pursued.
The donor area: the real budget is not money, it is follicles
The hard limit of every hair transplant is the donor area — the occipital and temporal band whose follicles are genetically resistant to hair loss. That band has finite capacity: over-harvesting depletes it visibly and irreversibly.
So the professional question is not just "how many grafts do I want?" but "how many can be safely extracted today, keeping a reserve for the future?" Hair loss is progressive: non-transplanted hair will follow its course, and a serious plan considers what your head will look like in 10 or 20 years, not just in the first-year photo.
How it is estimated at the consultation (and why there is no per-graft price here)
At the consultation, donor density is examined (with magnification or trichoscopy), along with hair caliber and the degree and pattern of loss, and a realistic coverage expectation is discussed. From that comes a graft count per zone and a plan: one session or several, extraction technique, and a hairline design appropriate to your age.
Dr. Arístides Arellano — an ISHRS member since 1996 — works hair restoration with FUE extraction, including the robotic ARTAS iX variant for follicular-unit selection and extraction in indicated cases.
On cost: at this practice, a hair transplant quote is defined at the consultation, based on the complete plan — we do not publish a per-graft price because the isolated figure, without a plan, invites apples-to-oranges comparisons. The reference list for other procedures is at prices.
Signs of a quote you should not trust
- You get an exact graft count over WhatsApp without anyone examining your scalp or even a photo of your donor area.
- They promise "unlimited grafts" or megasessions without mentioning your donor area’s limit.
- They count hairs and call them follicles to inflate the number.
- Nobody asks about your age, family history of hair loss, or your 10-year expectation.
- There is no physician in the conversation — only a sales advisor.
Frequently asked questions
How many hairs does each graft or follicular unit contain?
Between 1 and 4 hairs, averaging around 2.2. Single-hair units are reserved for the hairline, where naturalness demands individual hairs; 3- and 4-hair units provide density behind it. That is why 2,000 grafts equal roughly 4,000–5,000 hairs.
How many grafts are needed just for the temples?
As an order of magnitude, 800 to 1,500 grafts for moderate frontal recession. The real figure depends on your hair caliber, hair-to-skin contrast and an age-appropriate hairline design — it is defined by examining your scalp at a consultation.
Why do many clinics quote per graft and this practice does not?
Because an isolated per-graft price invites comparing numbers without a plan: it says nothing about who extracts, with which technique, which design, or how much donor reserve is preserved. At this practice the quote is built at the consultation around your case’s complete plan.
What if my donor area is not enough to cover everything?
Priorities are set: the hairline and facial frame usually deliver the most visual impact per graft invested. A serious plan may leave the crown for a second stage or manage it with partial-coverage expectations, and always preserves donor reserve for the future, because hair loss keeps progressing.
Can a hair transplant be done in two sessions?
Yes, and in advanced hair loss it is common. Splitting the plan respects safe per-session extraction limits, lets the first stage’s growth be assessed, and informs the second stage. The typical interval between sessions is several months to a year.
Will transplanted grafts reach the same density as my original hair?
Not 100%: young native scalp has more density than any transplant can replicate. The realistic surgical goal is cosmetically convincing density — hair that reads as normal to the eye and when styled. Results may vary per patient.
