## What is shock loss?

In the weeks after a hair transplant, some transplanted hairs, and sometimes existing hairs around the area, fall out. The root stays; only the hair shaft falls and the follicle enters a resting phase.

## When does it start and end?

It usually starts between weeks 2 and 8 and is most visible in month 2. New hairs start to grow from month 3.

## Why does it happen?

The follicle is briefly cut off from blood flow during transfer and enters a resting phase while healing. Nearby existing hairs can also react to the stress of the procedure.

## When to contact your doctor

- No growth at all by month 6,
- Increasing redness, discharge or pain in the recipient area,
- Clear, patchy loss in the donor area.

You can send photos on WhatsApp during this period to keep your progress followed.
