Yes. Transplanted hair can turn grey.

Hair transplants move a person's own follicles from a donor area to thinning areas. The follicles keep their original biology, so colour change follows normal ageing rather than being triggered by the move. Transplanted hair will go grey eventually, as all hair does, but the procedure does not cause or speed this up. This answer does not rest on a specific study. It rests on how follicle transplantation and hair pigmentation work.

• Transplanted follicles keep the genetic traits of the donor area, including when they lose pigment.
• Greying is driven by age and genetics, as pigment-producing cells in follicles decline, not by the surgery.
• Hair transplanted from a person who is already going grey will usually be grey or turn grey on the same timeline.
• Transplanted hair will go grey eventually with age, just like the rest of the person's hair.
• Synthetic hair implants are a different procedure. They were not approved by the US FDA, and synthetic fibres don't change colour with age.

Transplanted follicles continue producing real hair, so they remain subject to age-related colour changes. This means the transplanted hair can go grey over time—not that getting a transplant automatically makes it grey.

• A hair transplant moves your own living hair follicles into areas with thinning or missing hair.
• Hair turns grey when its follicles produce less of the pigment melanin.
• Hair that is already grey can also be transplanted successfully.

Modern hair transplants involve moving healthy, living hair follicles from a donor region (typically the back of the head) into thinning or bald areas. While these relocated follicles maintain their genetic resistance to dihydrotestosterone (DHT)—the hormone primarily responsible for androgenetic alopecia—they remain subject to normal cellular ageing. As a person ages, the melanocytes within the follicle bulbs gradually decrease melanin production, causing the hair to lose pigment and turn silver or white. The operation itself does not turn hair grey, nor does it halt greying; the transplanted hair will simply follow the genetic greying timeline of the patient's donor area.

• Hair transplants relocate living hair follicles, usually taken from the back and sides of the scalp.
• Transplanted hair follicles retain their donor traits, including resistance to baldness hormones, but they are not immune to biological ageing.
• Hair greying occurs when melanocytes within follicles produce less melanin over time due to genetics and age.
• Transplanted hair turns grey at roughly the same rate as the natural hair in the donor area from which it was taken.
• Hair transplant surgery does not accelerate natural greying or prevent hair from turning grey.

Hair transplants move the patient's own follicles from a donor area to a thinning area. The follicle, not its location, determines hair colour, so transplanted hair starts out matching the donor hair and greys on the same genetic schedule as the rest of the scalp hair. The evidence is consistent across surgical sources and basic hair biology; claims that the procedure itself turns hair grey are not supported, beyond normal ageing.

• Transplanted follicles keep the pigment behaviour of their donor site (donor dominance).
• Hair colour comes from melanocytes in the follicle, which make less melanin as people age.
• A transplant does not stop the natural greying process, so transplanted and native hair continue to change colour with age.
• Grey hair often appears first at the temples and back of the head, so donor hair can grey before the rest.
• Reports of grey hair appearing soon after a transplant are anecdotal; surgeons report it is not a common side effect of the procedure itself.

Hair implants (transplants) use the patient’s own hair follicles, typically from the back of the scalp. These follicles retain their original genetic programming, including the timeline for greying. As the donor area’s hair turns grey with age, the transplanted hair will do the same. The process is driven by the natural decline in melanin production, which is determined by genetics and aging, not by the transplant procedure. While there are rare reports of premature greying in some transplanted hair, this is not common and does not impact the overall health or longevity of the hair.

• Transplanted hair comes from the patient’s own donor area, usually the back of the scalp.
• Hair turns grey due to a natural decrease in melanin production as people age.
• The greying of transplanted hair follows the same timeline as the donor area’s natural hair.
• Genetics are the main factor in determining when and how quickly hair turns grey.
• On very rare occasions, the transplant procedure may cause some transplanted hair to grey prematurely, but this is uncommon and does not affect hair health.
