Localization of Mechanosensitive Channel TRPV4 in Mouse Skin

Microneedling can cause a sneezing reflex due to tingling in the nose. Users report this reaction, especially in the temple region.

Concerns about metal particles from dermapen or dermaroller needles potentially entering the skin and lymph nodes, similar to tattoo needles. Discussion includes the possibility of using Minoxidil, finasteride, and RU58841 for hair loss treatment.

Microneedling can cause sneezing and eye tearing due to nerve stimulation, particularly near the temples and forehead. Some users find it lessens over time, while others prefer using finasteride and minoxidil for hair growth.

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.

Microneedling with RU58841 may not be necessary since RU works topically by occupying receptors before DHT binds. RU58841 is a topical anti-androgen.

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.
