August 2016 in “PubMed” This article discusses the relationship between cortisol, stress, and hair follicle function and highlights oral supplementation with a specific proteoglycan as a promising treatment for stress-related hair growth disorders, but it does not present new clinical results.
13 citations
,
January 2016 in “Annals of Dermatology” This study found that acute stress in rats inhibits hair growth, likely through increased cortisol levels and activation of the substance P-mast cell pathway.
10 citations
,
October 2014 in “Plastic & Reconstructive Surgery Global Open” In this case study, Botulinum toxin type A injections were associated with improved hair growth and scalp condition in a patient with radiation-induced alopecia, though the mechanisms remain speculative.
76 citations
,
April 2013 in “PLoS ONE” The researchers reported that reactive oxygen species regulate the stress-induced SP-Mast cell pathway, which might support using antioxidants to treat stress-related hair loss.
24 citations
,
December 2010 in “Dermatologic surgery” In this study, BTXA injections did not effectively treat recalcitrant alopecia areata or improve hair regrowth in most patients, suggesting its limitations as an alternative therapy.
50 citations
,
November 2010 in “Plastic and Reconstructive Surgery” This study suggests that Botox injections may increase hair count and reduce hair loss in men with androgenetic alopecia, potentially through increased blood flow and oxygen to the scalp.
159 citations
,
November 2007 in “American Journal of Pathology” In this study, researchers found that substance P triggered premature catagen development and immune changes in human scalp hair follicles, providing a possible biological link between stress and hair loss conditions like telogen effluvium and alopecia areata.
26 citations
,
April 2006 in “Cephalalgia” Botulinum A toxin injections reduced pain and promoted hair regrowth in a woman with a rare form of alopecia areata.
224 citations
,
March 2006 in “Seminars in Cutaneous Medicine and Surgery” This article discusses the hair follicle's regenerative cycles and the molecular mechanisms influencing them, emphasizing the need for therapeutic targeting of the "hair cycle clock" to manage hair growth disorders, without reporting new research findings.
375 citations
,
February 2006 in “Journal of Cell Science” This article reviews the stages and regulation of the hair cycle, highlighting molecular regulators involved, but it does not present new research findings.
127 citations
,
December 2005 in “Experimental Dermatology” This study provides evidence that psychoemotional stress inhibits hair growth in mice by affecting the brain-hair follicle axis, with specific neuropeptides and treatments modulating this effect.
162 citations
,
August 2004 in “Journal of Investigative Dermatology” This study suggests that stress negatively affects hair growth by inducing inflammation and early hair cycle transitions in mice, which might inform strategies for managing stress-related hair loss in humans.
108 citations
,
July 2004 in “American Journal of Pathology” This study suggests that nerve growth factor plays a crucial role in the stress-induced termination of hair growth in mice, and its antagonism might offer a therapeutic approach to mitigate stress-related hair loss.
194 citations
,
March 2003 in “American Journal of Pathology” This study found that psychoemotional stress disrupts hair growth in mice by terminating anagen and suggests a potential pathway for pharmacological management of stress-related hair loss in humans.
