Different species and human skin models vary in their skin enzyme activities, with pig skin and some models closely matching human skin, useful for safety assessments and understanding the skin's protective roles.
Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
The conversation discusses topical androgen receptor blockers for hair loss, mentioning Clascoterone, Pyrilutamide, GT20029, and RU58841. Ketoconazole's effectiveness and application methods are also debated.
Hair loss discussion includes finasteride intolerance and questioning if Pyrilutamide is an alternative. Pyrilutamide not commercially available, but may be tolerable if approved since it's not a 5aR inhibitor.
Dutasteride and finasteride have similar risk profiles despite Dutasteride blocking more types of 5AR in the brain. Some users report no mood issues with either drug, and it is suggested that Dutasteride's larger molecular size may limit its ability to cross the blood-brain barrier.
Dutasteride may have fewer side effects than finasteride, with some users experiencing better hair maintenance. Experiences vary, with some preferring dutasteride for fewer side effects, while others see no significant hair improvement.
