Disease profile
A grounded synthesis of the condition — overview, causes, mechanism, risk factors and current standard of care.
Alopecia is the absence of hair from areas where hair is normally present. The supplied grounding also indicates that hair loss can be discussed in specific forms such as androgenetic alopecia and chemotherapy-induced alopecia, but the core definition is simply loss of hair.
The grounding supports a genetic contribution for androgenetic alopecia, and it also identifies chemotherapy as a cause of chemotherapy-induced alopecia. Beyond these examples, no broader aetiology is supported in the supplied material.
The supplied reviews point to hair follicle biology and follicle cycling as central to hair loss, with androgenetic alopecia involving molecular and transcriptional differences between balding and non-balding scalp regions. For chemotherapy-induced alopecia, anticancer agents damage the hair follicle and alter subsequent follicle pathophysiology. Stem-cell and Wnt/growth-factor signaling are discussed as mechanisms relevant to hair regrowth and follicle development, but not as established disease mechanisms for all alopecia.
For androgenetic alopecia, genetics and aging are supported risk factors, and lifestyle is also mentioned as a contributing factor. No other general risk factors are supported by the supplied grounding.
For chemotherapy-induced alopecia, scalp cooling is described as the only safe U.S. FDA-cleared prevention modality in the supplied review. The other grounded literature discusses regenerative and stem-cell-based approaches, platelet-rich plasma, and growth-factor or Wnt-pathway-related strategies for hair regrowth, but these are presented as investigational or emerging rather than established standard care.
