October 2000 in “Nature” This study found that RXRα plays a critical role in hair cycling and keratinocyte functions in mice, likely through its interaction with VDR in epidermal cells.
9 citations
,
May 2002 in “PubMed” This study demonstrated that mice lacking skin-specific RXRalpha expression developed hair follicle degeneration and alopecia, indicating the importance of RXRalpha/VDR heterodimers in maintaining hair follicle homeostasis.
127 citations
,
July 2002 in “EMBO journal” This study found that RXRα/RARγ heterodimers are necessary for retinoic acid-induced keratinocyte proliferation in the skin, while normal epidermal maintenance does not require RAR-mediated signaling.
109 citations
,
October 2007 in “Journal of pineal research” This study suggests that melatonin plays a role in hair follicle function by modulating growth and pigmentation, and it may act as a protective agent in active hair growth phases.

August 1995 in “British journal of dermatology/British journal of dermatology, Supplement” This study found that RXR-alpha is strongly expressed in both normal and psoriatic human skin, suggesting it may play a role in the transition from proliferation to differentiation in epidermal keratinocytes.
