A new classification for depth control in hair restoration surgery was proposed, dividing it into three grades based on the depth required for successful graft extraction.
Microneedling with 0.6 mm needles combined with 5% minoxidil is more effective for hair count and thickness than minoxidil alone or with 1.2 mm needles. Biweekly microneedling at 0.6 mm depth is recommended for better results in treating androgenetic alopecia.
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.
Microneedling frequency and depth, with suggested protocols involving 0.3mm every day before applying topical treatments like Minoxidil or Finasteride, and 0.5-1.5mm once or twice a month for wounding.
Microneedling depth should be customized based on hair type and scalp area, with many users finding 0.5-0.6mm effective for miniaturized hairs to avoid damage. Users report varying pain levels and results, with some preferring shorter needle lengths and others using longer ones like 1.75mm for scalp health and density improvement.
Microneedling should target depths of 0.5mm to 1.5mm for hair loss, with weekly sessions at 1mm recommended. Combining microneedling with Minoxidil is common for improved results.
