5 / 1000+ resultscommunity Is the “crunching” sound during microneedling my scalp actually the needles cutting through hair?
The "crunching" sound during microneedling is likely the needles penetrating the scalp's outer layers, not cutting hair. Users suggest using a derma stamp instead of a roller to avoid potential hair damage.
community Can microneedling damage existing hair?
Microneedling is unlikely to damage existing hair if done with a device using a smaller needle count, like a 9-needle cartridge, and a stamping motion. Hair follicles are deeper than the typical needle penetration depth.
community "When comparing 5% minoxidil with 0.60 mm or 1.20 mm needle lengths, Faghihi et al. found that 0.60 mm needle lengths led to significant hair count and diameter increases versus 5% minoxidil, whereas 1.20 mm needle lengths only saw hair count increases versus 5% minoxidil"
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.
community Micro needling 25 days progress. I’ve been on fin and min for 6 months but micro needling has done SO much more to actually restore my hairline
A user shared a 25-day progress picture showing significant hairline restoration attributed to microneedling, in addition to using minoxidil and finasteride for 6 months. Other users discussed needle length, frequency, and whether the effects of microneedling are permanent.
community Where have all the microneedle pens gone?
Microneedle pens for hair loss are harder to find on Amazon due to FDA regulations on needle length. Users suggest buying from AliExpress or Temu instead.
