Studysummary In this study, hair color changes in piebald rats after skin grafting suggest that such changes are more likely due to the surgical process than the new environment. Our plain-language summary of this paper — not a Tressless recommendation.
In a study on hooded rats, researchers observed that skin transplanted from areas producing black hair often grew white hair in its new location. This change was also noted when the skin was sutured back to its original site, indicating that the white hair resulted from the surgical procedure rather than environmental factors. These findings contrast with previous research on guinea pigs, which showed that hair follicles retained their pigment-producing abilities after transplantation.
