Immunopathogenesis of Primary Cicatricial Alopecia

Hair follicle stem cells remain in bald individuals, but progenitor cells do not, raising questions about hair regrowth claims by Pelage. PP405 is discussed as a potential treatment, with skepticism about its effectiveness compared to existing treatments like Minoxidil and Finasteride.

Lichen Planopilaris (LPP) is an autoimmune condition causing permanent hair loss and fibrosis, often misdiagnosed. Treatments include pioglitazone, topical corticosteroids, anti-inflammatory medication, and Jak inhibitors.

A new treatment using dermal sheath cup cells may regrow hair and could require repeat treatments every 8 years. Users discuss ongoing trials and plan to use finasteride and minoxidil until the treatment is available.

Exosomes combined with fractional picosecond laser treatment were effective in treating androgenetic alopecia and promoting repigmentation in white hair patches. The role of exosomes in hair repigmentation, particularly in conditions like poliosis, is not well-studied.

Hair follicle regeneration through stem cell rearrangement is discussed, focusing on bioengineered cellular structures rather than traditional hair transplants. Treatments mentioned include Minoxidil, finasteride, and RU58841.

Adipose-derived stem cells with ATP improved hair regrowth in male and female mice with androgenetic alopecia. The most effective treatments were low dose stem cells with ATP for males and medium dose stem cells with non-liposomal ATP for females.
