This post and conversation are about the molecular mechanisms triggered by microneedling, specifically its effects on inflammation, tissue remodeling, epithelial proliferation, differentiation, and collagen synthesis. The discussion highlights the potential benefits of microneedling for hair loss treatment.
The user has been using topical finasteride and minoxidil for two years with decent regrowth and recently added microneedling to their routine. They are questioning if the small hairs observed are new regrowth from microneedling or just vellus or miniaturized hairs.
Microneedling stimulates hair growth through stem cell activation during wound healing, not just increased blood flow. Other methods like showers or supplements don't replicate this effect.
Microneedling at depths greater than 0.6 mm may damage miniaturized hair follicles, with 0.5 mm showing better results for hair regrowth. Combining microneedling with minoxidil enhances absorption, but caution is advised to avoid damaging follicles.
The conversation is about someone experiencing a lot of bleeding from using a 1.0mm microneedling device for hair loss treatment and asking if it's normal. Various users suggest that the bleeding is excessive and recommend using shorter needles or less pressure, while others share their own microneedling practices with different needle lengths and no bleeding.
