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,
January 2015 in “Journal of Biological Rhythms” The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.
127 citations,
December 2005 in “Experimental Dermatology” Stress can stop hair growth in mice, and treatments can reverse this effect.
126 citations,
January 2009 in “International Journal of Trichology” Oxidative stress contributes to hair graying and loss as we age.
126 citations,
January 1987 in “Journal of The American Academy of Dermatology” The document concludes that understanding hair structure is key to diagnosing hair abnormalities and recommends gentle hair care for management.
125 citations,
September 2001 in “The FASEB Journal” Stress can cause hair loss by negatively affecting hair follicles and this effect might be reversed with specific treatments.
