Dutasteride takes 1-3 months to affect scalp DHT levels, not just a week. The prostate absorbs Dutasteride faster than the scalp due to different vascularnetworks and enzyme densities.
Switching from finasteride to dutasteride involves gradually increasing dutasteride while decreasing finasteride. Studies show dutasteride 0.5 mg daily can improve hair density in men unresponsive to finasteride.
The user experienced positive hair growth results using microneedling with rosemary and mint oil, without Minoxidil, Finasteride, or RU58841. They switched from a dermaroller to a microneedling pen and targeted different scalp areas weekly.
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.
