Most people reading this are somewhere between day three and month three, and they are worried about something specific. The swelling that will not go down. The crusts that are still there on day eight. Or the worst one: the hair they paid for is falling out.
Below is what happens at each stage and, more usefully, what the published research says is normal at that stage. Every number on this page comes from a study, and the studies are listed at the bottom.
The two numbers that explain most of the panic
In 2019 a team at a hair restoration centre ran a tightly controlled comparison. They marked three one-centimetre blocks on the scalp, made thirty slits in each, and implanted single follicular units under identical conditions so they could count exactly what happened to each one.
Of the scalp-to-scalp grafts, 40% shed their hair shafts within the first two months. At the twelve-month check, 89% of those same grafts were growing hair.1
Read those two numbers together, because between them they are the whole story of the first year. Shedding is not the opposite of survival. The shaft falls out. The follicle stays in the skin and grows a new one on its own schedule.
Days 0 to 3: swelling
Swelling across the forehead and around the eyes affects roughly 40% to 50% of patients. It appears on day one or two, peaks on days two and three, and settles within five to seven days.2
It looks far worse than it is, and it is not a complication. This is why clinics tell you to sleep with your head elevated for the first few nights.
Although the evidence for sleeping elevated is weaker than most people assume. We have covered what the studies found in hair transplant swelling: what actually prevents it.
Days 1 to 3: the grafts find a blood supply
For the first few days a transplanted follicular unit is a piece of living tissue with no blood supply of its own. Reviewing the surgical literature, Parsley and Perez-Meza note that grafts take approximately three days before they begin to regain their blood supply.3
That single fact is behind every instruction you were given for the first seventy-two hours. No rubbing. No pressure on the recipient area. No hat sitting on the grafts. No sweating.
Days 2 to 10: crusts
Crusts form within two to three days and resolve by seven to ten days with appropriate care.2 Each one is dried plasma, blood and skin sitting around the base of a graft.
Trying to speed them up is the most common way people damage an otherwise good result. We have written a separate page on exactly when they come off and how to wash without pulling anything: hair transplant scabs, when they fall off.
Within 72 hours: the first wash
Current guidance is early and gentle, not late and cautious. Saline or a mild shampoo within twenty-four to seventy-two hours is what the evidence supports, and delaying the first wash beyond three days is associated with a higher rate of infection, not a lower one.2
Follow your own surgeon first. If their instruction differs from this, theirs wins, because they know what they did to your scalp.
Day 9: the grafts are anchored
Bernstein and Rassman tested this directly rather than estimating it. Across 42 patients they performed 289 graft pull tests at different points after surgery, applying measured traction to see when a graft would resist coming out. In the first week grafts could still be dislodged. By day nine they were fully anchored.4
Day nine is the line between careful and normal. Before it, the graft depends on how you handle it. After it, it is held in place by healed tissue.
Weeks 1 to 4: folliculitis
Small inflamed spots around emerging hairs affect around 12% of patients, typically within the first four weeks.2 Most cases are mild and settle with continued gentle washing.
Spreading redness, pus, fever, or pain that increases after day three is different. That is a same-day phone call to your clinic, not something to read about online.
Weeks 2 to 8: the shedding phase
This is the stage that generates the worried messages. The transplanted hairs start falling out, often in the shower, often in visible numbers.
It is the expected path. The surgery pushes the transplanted follicle into a resting phase, it releases the shaft it was holding, and then it rebuilds. The 40% figure from the counting study above is what that looks like in practice, against 89% of those follicles growing at one year.1
Weeks 2 to 8: shock loss in the hair around the grafts
Separately from the transplanted hairs, some of the existing hair around the recipient area can shed too. Reported incidence across the literature ranges widely, from 0.15% to 15%. It begins two to eight weeks after surgery, and regrowth usually starts around three months.2
This one frightens people more than the graft shedding, because it looks like the surgery has made things worse. In the large majority of cases it is temporary.
It is also far more common in women than in men: 1.6% of men against about 21% of women in a study of 621 patients. We have covered that separately in shock loss after a hair transplant.
Months 3 to 4: growth starts
Regrowth of shed hair typically begins around three months.2 The first hairs through are fine, pale and sparse, and they do not look like the result you were shown. They are not meant to yet.
Month 6: visible, not final
By six months most people have real coverage. Density is still building, individual hairs are still thickening, and follicles that woke up late are still arriving.
Month 12: the result
Final growth is typically achieved around twelve months after surgery. That is also why surgeons will not assess a result properly or plan a second procedure before the twelve-month mark.2
The whole timeline on one page
| Stage | When | What is normal |
|---|---|---|
| Swelling | Day 1 to 3, gone by day 5 to 7 | 40% to 50% of patients |
| Grafts regain blood supply | Around day 3 | No pressure, no rubbing |
| Crusts | Form day 2 to 3, gone day 7 to 10 | Let them lift on their own |
| First wash | 24 to 72 hours | Gentle, and not delayed |
| Grafts anchored | Day 9 | Normal washing from here |
| Folliculitis | Week 1 to 4 | Around 12% of patients |
| Transplanted hair sheds | Week 2 to 8 | Around 40% of grafts |
| Shock loss of existing hair | Week 2 to 8 | 0.15% to 15% |
| Regrowth begins | Month 3 to 4 | Fine and pale at first |
| Visible coverage | Month 6 | Still not final density |
| Final result | Month 12 | The point of assessment |
What changes in your routine, and when
Weeks 1 to 4: washing is the whole job
In this window the only thing that matters is cleaning the scalp without applying force to it. A shampoo made for this phase is mild, low-foaming and rinses clear, so you are not working lather through healing grafts. Ours is the Rise Plus Post Transplant Repair Shampoo.
From month 1: scalp serums
Once crusts are gone and the skin is intact, most clinics introduce a leave-in scalp serum. Do not start one earlier than your surgeon allows, and do not apply anything to broken skin. The Rise Plus 5% Procapil Repair Serum is the one we stock for this phase.
Throughout: the supplement question
Biotin contributes to the maintenance of normal hair, which is an authorised health claim rather than a marketing line. It is not a growth accelerator and no supplement will change the twelve-month timeline above. What it does is remove a deficiency as a variable during the year your follicles are rebuilding. We stock MD Plus Advanced Hair Multivitamin for this.
If you would rather not assemble it yourself, the post transplant care sets are grouped by month so the right product is in your hand at the right stage.
When to stop reading and ring your clinic
- Redness that is spreading rather than fading
- Pus, or crusts that return thick and yellow after they had cleared
- Fever
- Pain that increases after day three instead of easing
- Bleeding that does not stop with gentle pressure
- A graft that comes away with obvious tissue attached
None of these are common. All of them are worth a phone call the same day.
