The transition from growth to regression in Cashmere goat hairfollicles involves changes in expression of genes related to keratin and cell differentiation.
HMI-115, a newly discovered hair loss treatment that could potentially be effective for those with diffuse thinning and telogen effluvium. It is based on prolactin receptor antagonist signaling and has already undergone Phase I trials in women, with potential commercialization by 2027.
Tretinoin can cause non-telogen hair loss in some men by inducing catagen-like changes in hairfollicles and through retinoid toxicity, especially when used with minoxidil. Some users report hair loss even when using retinoids on the face, while others experience benefits when combined with treatments like finasteride and minoxidil.
Hairfollicles can be dormant and potentially revived with treatments like finasteride and minoxidil, but irreversible loss occurs if certain structures are destroyed. Early intervention is more effective, and additional methods like microneedling may help.
Cannabis and THC may have mixed effects on hair, with some studies suggesting potential negative impacts on hair growth in isolated hairfollicles, but these results are hard to apply to living humans. Treatments like minoxidil and finasteride are commonly used for hair loss, and the effects of cannabis might be neutral or vary based on individual factors.
PP405 is a new hair loss treatment in phase 2 trials that may promote hair growth by increasing lactate production and activating hair follicle stem cells. It could potentially replace hormone-disrupting treatments like Minoxidil and finasteride.
