A New Approach with Combined Microneedle and Sublative Fractional Radiofrequency for Photoaging Management: A Clinical, Histometric, and Immunohistochemical Study

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 user experienced hairline improvement using microneedling once a month with a 12-pin set at 1.5-2.0mm and taking Tru Niagen, alongside a heavily modified diet. They attribute the slow hairline improvement to environmental factors, particularly diet, rather than solely genetic factors.

Microneedling can enhance hair growth by improving minoxidil absorption and stimulating blood flow. Users discuss optimal needle depths, with some favoring shallow frequent needling for better absorption and others preferring deeper needling for stem cell activation.

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.

An 18-year-old is seeking advice on microneedling while using RU58841 for hair loss. Recommendations include using a derma pen with 0.5mm needles every two weeks and avoiding RU application for 24 hours post-microneedling to prevent absorption into the bloodstream.

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.
