Shock loss after FUT is completely normal and happens to virtually every patient. Transplanted hairs begin shedding 2-4 weeks after surgery as the follicles enter a resting phase from the trauma of extraction and reimplantation. The hair shafts fall out, but the living follicle roots remain anchored beneath the skin and will produce new growth starting around month 3-4.
Shock Loss Timeline
| Timeframe | What Happens | Patient Experience |
|---|---|---|
| Week 1 | Grafts anchor into recipient sites | Scabbing, mild redness |
| Weeks 2-4 | Transplanted hair shafts begin falling out | Hairs shed during washing and on pillowcase |
| Weeks 4-8 | Most transplanted shafts have fallen out | Recipient area may look like pre-surgery |
| Weeks 8-12 | Dormant phase; follicles resting beneath skin | Little visible change; patience required |
| Month 3-4 | New hairs begin emerging | Fine, thin hairs appear |
| Month 6-8 | Significant new growth visible | 50-60% of final density |
| Month 12-18 | Full results | Final thickness and density achieved |
Why Shock Loss Happens
When a follicular unit is removed from the donor area and placed into a recipient site, it loses its blood supply temporarily. The follicle survives because hair follicles are remarkably resilient, but the existing hair shaft can no longer be sustained. The follicle enters telogen (the resting phase of the hair cycle), the old shaft falls out, and the follicle eventually begins producing a brand-new hair in the anagen (growth) phase.
This process is identical whether the grafts came from a FUT strip or FUE extraction. The biology of follicular cycling does not change based on the harvesting method.
Two Types of Shock Loss
Transplanted Hair Shock Loss
This affects nearly 100% of FUT patients. The transplanted hairs fall out within 2-4 weeks. This is expected, unavoidable, and not a cause for concern. Every hair that falls out during this window was going to shed regardless.
Native Hair Shock Loss
This is less common but more distressing. The tiny incisions made in the recipient area to place grafts can traumatize nearby existing (native) hairs, causing them to enter telogen and shed temporarily. This affects roughly 10-15% of patients and is more common in areas where native hair is already miniaturized (thinning).
| Type | Frequency | Recovery | Prevention |
|---|---|---|---|
| Transplanted hair shedding | ~100% of patients | New growth at month 3-4 | Cannot be prevented |
| Native hair shedding | ~10-15% of patients | Regrows within 3-6 months | Finasteride, minoxidil, PRP |
The Ugly Duckling Phase
The period between shock loss completion (around week 4-6) and visible new growth (month 3-4) is often the hardest emotionally. Your recipient area may look the same as or worse than before surgery. Some patients panic during this phase, thinking the procedure failed.
How to Manage the Waiting Period
- Remind yourself that 90-95% of grafts survive FUT. The follicles are alive, just resting
- Avoid obsessively checking the mirror daily. Changes are gradual and hard to see day-to-day
- Take standardized photos monthly (same lighting, same angle) to track real progress
- Stay in communication with your surgeon's clinic if you have concerns
- Continue all prescribed medications, especially finasteride and minoxidil
Reducing Native Hair Shock Loss
While you cannot prevent transplanted hairs from shedding, you can reduce the risk of native hair shock loss in the surrounding area.
Medications That Help
- Finasteride (1mg daily): Strengthens native hairs by blocking DHT. Starting finasteride before surgery is ideal
- Minoxidil (5% topical): Begin applying 2-4 weeks post-surgery as directed by your surgeon. Increases blood flow to the scalp and supports follicle cycling
- PRP injections: Some surgeons inject Platelet-Rich Plasma into the recipient area at the time of surgery or 1-3 months post-op to reduce native hair shock loss
When to Contact Your Surgeon
Shock loss is normal, but certain signs warrant contacting your clinic.
- No new growth by month 5-6 (most patients see something by month 4)
- Signs of infection: increasing redness, warmth, pus, or fever
- Significant pain that worsens rather than improves after week 1
- Widespread native hair loss beyond the immediate transplant zone
These situations are uncommon but should be evaluated promptly.

FAQ
What is shock loss after FUT?
Shock loss is the temporary shedding of transplanted hairs that occurs 2-4 weeks after FUT surgery. The transplanted hair shafts fall out as the follicles enter a resting phase (telogen) due to the trauma of being removed and reimplanted. The follicles themselves remain alive beneath the skin and will produce new growth starting around month 3-4.
Is shock loss a sign that grafts failed?
No. Shock loss is a normal part of the hair transplant cycle and occurs in virtually all patients regardless of method (FUT, FUE, or DHI). The hair shafts shed, but the follicle roots remain viable. Graft failure would mean no new growth at 6-12 months, which is a completely separate issue affecting only 5-10% of transplanted grafts.
How long does shock loss last after FUT?
Shock loss typically begins 2-4 weeks after surgery and lasts 2-3 months. By month 3-4, new hair begins growing from the transplanted follicles. Full regrowth takes 12-18 months. The period between shock loss and visible new growth (roughly weeks 4-12) is often called the ugly duckling phase.
Can shock loss affect existing non-transplanted hair?
Yes. In some cases, the trauma of recipient site creation (the tiny incisions where grafts are placed) can cause nearby native hairs to temporarily shed. This is called recipient area shock loss and affects roughly 10-15% of patients. These native hairs almost always grow back within 3-6 months.
How do I reduce shock loss after FUT?
You cannot prevent shock loss of transplanted hairs because it is a natural biological response. However, finasteride and minoxidil can reduce shock loss of native (non-transplanted) hairs in the surrounding area. Some surgeons also offer PRP (Platelet-Rich Plasma) injections to minimize native hair shedding.
