You invested in your hair. Protect the regrowth.

After a transplant, grafted hairs often fall before regrowing — that is shock loss, and it is normal. But the weeks after the procedure determine the quality of the result you have waited months for.

Understand

Shedding after a transplant is not a failure. It is a stage.

A few weeks after the procedure, seeing newly grafted hairs fall is one of the most unsettling moments. This is shock loss: under the shock of surgery and temporary interruption of blood supply, the hair shaft falls — but the follicle remains in place and viable.

What matters in this window is not graft survival, but the environment in which they will restart : an inflamed, poorly perfused or weakened scalp does not offer the same regrowth conditions as calm, prepared tissue. Supporting this phase puts the odds on the side of the result you paid for.

Why support matters

A transplant is an investment. Its regrowth is prepared.

A transplant represents a considerable financial and personal commitment — in Western Europe, the procedure most often costs between €4,000 and €12,000 depending on graft count and country (around €3,900 to €8,000 in Paris). Yet attention focuses on the surgical act, rarely on the months of regrowth that determine the outcome.

The logic is the same as for any hair reconstruction: prepare the ground before regrowth settles in. Soothe perifollicular inflammation, support microcirculation and tissue quality — conditions to work on from healing, not once regrowth has already started.

Frequently asked questions

What is shock loss after a transplant?

It is temporary shedding of grafted hairs — and sometimes neighbouring native hairs — usually 2 to 4 weeks after the procedure. It is normal and expected: only the shaft falls; the follicle remains under the scalp and prepares new growth. It is not transplant failure.

The shaft falls, the follicle remains. It is a stage, not a failure.

When does hair regrow after a transplant?

After shedding, a 1 to 2 month dormancy precedes regrowth. First fine hairs appear between months 3 and 4, density builds from month 6, and the full result is assessed around 12 months — sometimes up to 15–18 months.

How to support the scalp after a transplant?

Once initial healing is complete, the goal is to restore a favourable follicular environment: soothe inflammation, support microcirculation and tissue quality. A scalp reconstruction treatment can be applied from day 10 after the procedure, unless your surgeon advises otherwise.

Support possible from day 10, after surgeon approval.

Can a treatment improve transplant results?

A cosmetic treatment does not create follicles and does not replace surgery. It acts on the regrowth environment — inflammation, microcirculation, barrier function, tissue suppleness — to favour quality regrowth conditions. Your surgeon's follow-up remains the reference.

Is shock loss permanent?

No, in the vast majority of cases. Shedding affects the shaft, not the follicle, which remains viable and re-enters growth after a few months. Prolonged absence of regrowth or persistent inflammation should be reported to the surgeon.

The journey, in order

From the procedure to settled result.

Day 1 to day 10
Healing

Protect the grafts

Extraction and implantation sites heal. Protect the area and follow the surgeon's instructions scrupulously. No handling, no friction.

From day 10
Preparing the ground

Restore the environment

Once initial healing is complete, soothe inflammation and support microcirculation — prepare the scalp before regrowth, unless your surgeon advises otherwise.

2 to 4 wks
Shock loss

Expected shedding

Grafted hairs fall. The most unsettling moment, and the most normal. The follicle stays in place. Well-prepared tissue faces this phase in better conditions.

3 to 12 months
Regrowth & densification

The result takes shape

Fine regrowth then progressive densification. Texture and density build until a full result around 12 months. Patience is the rule.

The RENASCOR protocol

We rebuild before we stimulate.

REDACTIV® 1 is our early reconstruction treatment, 99% naturally derived. After hair implant, from day 10, it restores the follicular environment — microcirculation, perifollicular inflammation, tissue quality — to prepare quality regrowth. No minoxidil, no hormonal active. It does not create follicles: it prepares the ground for those that were grafted.
