46 citations,
March 2015 in “Regeneration” Mice can grow new hair follicles after skin wounds through a process not involving existing hair stem cells, but requiring more research to understand fully.
36 citations,
July 2014 in “Experimental Dermatology” Skin and hair can regenerate after injury due to changes in gene activity, with potential links to how cancer spreads. Future research should focus on how new hair follicles form and the processes that trigger their creation.
35 citations,

14 citations,
May 2021 in “Marine Drugs” PDRN, derived from salmon sperm, shows promise in healing wounds, reducing inflammation, and regenerating tissues, but more research is needed to understand its mechanisms and improve its use.
11 citations,
January 2011 in “Indian Dermatology Online Journal” Eating dairy and high glycemic foods may increase the risk of acne.
6 citations,
February 2014 in “Experimental Dermatology” Hair follicle regeneration is possible but challenging, especially in humans, due to the need for specific cells and a better understanding of how they signal growth.
2 citations,
July 2021 in “Journal of The European Academy of Dermatology and Venereology” Many 20th century politicians had skin conditions, with vitiligo being most common, affecting their image and political life.
2 citations,
April 2019 in “Experimental Dermatology” The article concludes that studying how skin forms is key to understanding skin diseases and improving regenerative medicine.
November 2013 in “Elsevier eBooks” Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.
Eating more protein during weight loss can prevent hair loss caused by not having enough protein.
408 citations,
January 2017 in “Science” Some wound-healing cells can turn into fat cells around new hair growth in mice.
301 citations,
February 2019 in “Nature Communications” The research found that different types of fibroblasts are involved in wound healing and that some blood cells can turn into fat cells during this process.
212 citations,
September 2015 in “Journal of Investigative Dermatology” The document provides a method to classify human hair growth stages using a model with human scalp on mice, aiming to standardize hair research.
210 citations,
November 2015 in “The Lancet HIV” PrEP for HIV is less effective in transgender women mainly due to low adherence to the treatment.
168 citations,
August 2000 in “American Journal of Pathology” Fibromodulin might help reduce scarring if increased in adult wounds like in fetal skin that heals without scars.
145 citations,
November 2018 in “Nature Communications” The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.
144 citations,
September 2012 in “Genes & development” Aging causes skin stem cells to work less effectively.
75 citations,
March 2014 in “Journal of Investigative Dermatology” Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.
73 citations,
June 2001 in “Endocrinology” Prolactin affects when mice shed and grow hair.
66 citations,
July 2015 in “Journal of Molecular Biology” The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.
61 citations,
June 2018 in “Proceedings of the National Academy of Sciences of the United States of America” Light can turn on hair growth cells through a nerve path starting in the eyes.

42 citations,
January 2014 in “Cold Spring Harbor Perspectives in Medicine” Hair growth is influenced by various body and external factors, and neighboring hairs communicate to synchronize regeneration.
38 citations,
October 1988 in “Clinics in Dermatology” Hormones, nutrition, and seasonal changes regulate hair growth cycles, with androgens extending growth phases and factors like aging and malnutrition affecting hair loss and thinning.
29 citations,
May 2020 in “npj Regenerative Medicine” Immune cells help regulate hair growth, and better understanding this can improve hair loss treatments.
