The user is experiencing thicker hair after using oral minoxidil, dutasteride, biotin, collagen shampoo with rosemary, and ketoconazole. They are considering adding a derma roller to their regimen for potential benefits.
Finasteride and minoxidil use resulted in a more youthful appearance and improved skin. There is debate about their effects on collagen and skin aging, with no solid evidence supporting significant changes due to finasteride.
Microneedling is effective for hair growth, especially when combined with finasteride and minoxidil, but concerns exist about potential long-term skin damage. Users report increased collagen and elastin deposition, but the long-term effects on the scalp remain uncertain.
Aminexil/Kopexil may help reduce hair loss by addressing perifollicular fibrosis in androgenetic alopecia, but it lacks the extensive clinical backing of finasteride and minoxidil. Some users find it effective, but availability and cost are issues, especially in the US where it's not FDA-approved.
Microneedling's effectiveness for hair regrowth is debated, with mixed results from studies. Some believe it helps with blood flow and scalp health, while others see it as largely ineffective.
