Confirmed five years of wig use (~2011–2016) due to severe chemical damage from constant on-set dyeing across the Pirates / Pride and Prejudice / Atonement / Anna Karenina film cycles. Her own words: hair "literally began to fall out." Recovered after pregnancy plus a break from chemical processing. NOT pattern loss — follicle health was intact, the shaft was breaking. Clearest case of follicle vs shaft health.
Chemical-induced damage and breakage, not pattern alopecia. From repeated dye jobs for film roles.
Damage accumulated over multiple film roles in her twenties; she went to wigs in her late 20s / early 30s.
Hair recovered after pregnancy and a five-year break in active dyeing.
Chemical damage (essentially trichorrhexis-style fragility from peroxide exposure).
In 2016 she clarified she wasn't bald, just heavily damaged: "It got so bad that my hair literally began to fall out of my head."
Wig-wearing for five years (~2011–2016) on red carpets and off-set, allowing natural hair to recover.
She publicly clarified she does not have pattern hair loss.
Stopping color treatments, plus pregnancy, which she says coincided with regrowth.

Knightley's case is the clearest celebrity demonstration that follicle health and shaft health are different problems. A patient with damaged-looking, breaking hair from styling / dye doesn't need a transplant — they need to stop the offending chemical exposure and let new growth come in. Wigs are a perfectly legitimate treatment for the cosmetic gap during recovery.
Medical literature: Breakage from repeated bleach / peroxide is well-documented in trichology literature: the hair shaft loses tensile strength, becomes porous, and snaps mid-shaft. Recovery is possible only because the follicle itself is unharmed; the visible regrowth is the original follicle producing healthy new hair once the chemical insult stops. Postpartum hormone shifts can also temporarily increase hair density (the inverse of postpartum telogen effluvium).
Observable record: Knightley personally confirmed in 2016 interviews (TIME, Marie Claire UK) that she had been wearing wigs for approximately five years due to extensive hair damage from constant on-set dyeing across the Pirates / Pride and Prejudice / Atonement / Anna Karenina film cycles. She described her hair as having "literally began to fall out." Per her account, the hair recovered following pregnancy.
Technique read: Not a hair-restoration case. Knightley's documented hair issue was acute damage from chemical processing, not pattern hair loss. Treatment was time off from chemical exposure and wig use during recovery.
If it were our case: Not applicable.
Included as a public-record reference for severe styling-related damage. The honest takeaway: hair can sustain real damage from sustained chemical processing, but with proper rest typically recovers — particularly if the underlying follicles are healthy. Knightley's case ended in recovery, not in pattern loss.
