What is shock loss, and why does it happen?
A calm explanation of how the temporary shedding that may be seen in the first months after a transplant relates to the hair growth cycle.
The hair cycle
Every hair follicle passes through growth (anagen), transition (catagen) and resting (telogen) phases. A stressor such as surgery can cause some follicles to move into the resting phase.
When is it seen?
It is common for some of the transplanted hairs to shed within the first 1–3 months. In some people, temporary shedding may also affect existing hair around the recipient area.
Because the follicles remain in place, new growth generally begins after month 3–4.
When should you seek advice?
If the shedding lasts longer than expected, or if you notice pain, redness or discharge on the scalp, message your coordinator so that your doctor can assess it.
