May 2015 in “Cell Stem Cell” Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.
127 citations,

119 citations,
January 2014 in “Indian Journal of Dermatology, Venereology and Leprology” Platelet-rich plasma might help with hair growth and skin conditions, but more research is needed to prove its effectiveness and safety.
118 citations,
January 2016 in “Current Topics in Developmental Biology” The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.
117 citations,
March 2017 in “Nature Communications” Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

116 citations,
May 2013 in “Proceedings of the National Academy of Sciences of the United States of America” Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.
116 citations,
September 2001 in “Journal of The American Academy of Dermatology” Hair loss occurs due to fewer papillary cells, smaller follicles, and shorter growth phases.
115 citations,
September 2012 in “Experimental Dermatology” Androgens have complex effects on hair growth, promoting it in some areas but causing hair loss in others, and our understanding of this is still evolving.
113 citations,
June 2015 in “Stem Cell Research & Therapy” Wnt and Notch signaling help wound healing by promoting cell growth and regulating cell differentiation.
112 citations,
January 2014 in “Molecular and cellular therapies” Blocking the Wnt pathway could lead to new treatments for cancer and tissue repair but requires careful development to avoid side effects.
