What is shock loss and why does it happen?

Seeing new hairs shed in the mirror a few weeks after a transplant is the first worrying moment for many patients. This phase is commonly called “shock loss” and is a normal part of healing.

The hair cycle in brief

Each hair passes through growth (anagen), transition (catagen) and resting (telogen) phases. At the end of the resting phase the hair sheds and a new one grows from the same follicle. During a transplant follicles are relocated and briefly stressed, which can push many transplanted hairs into the resting phase.

When and how much?

Shock loss usually appears 2 to 8 weeks after the procedure. Some or most transplanted hairs may shed, depending on the person. The follicle stays in place beneath the skin and starts producing new hair from months 3–4.

Shedding of existing hair

Sometimes existing fine hairs around the treated area also shed temporarily. This is more common in women and in densification procedures. It is usually temporary, although some hairs that were already miniaturised may not return.

What helps?

• Following aftercare instructions consistently
• Avoiding smoking and alcohol
• Balanced nutrition and enough sleep
• Supportive treatments, if your doctor recommends them

When to contact your doctor

• If shedding comes with marked redness, pain or discharge
• If pimple-like, inflamed bumps multiply in the treated area
• If there is no growth at all after month four
• If you notice unexpected thinning in the donor area

Patience

Shock loss says nothing about the final outcome. The real assessment comes at month 12, or month 18 at the crown. Uploading monthly photos to the patient portal lets you follow the change far more accurately than a daily look in the mirror.
