Proteomic Evaluation of Four Botanical Extracts on Skin Cells

OP injured their temple using derma rolling and tretinoin, causing peeling and potential hair follicle damage. Users suggest the injury might be permanent, possibly resulting in scar tissue where hair won't grow.

The user has been using minoxidil and finasteride for hair loss but is now considering microneedling due to recent hairline regression. Another user reassures that derma rolling causes only slight redness, which usually heals overnight.

The conversation discusses scalp itching and tenderness after microneedling, despite using medicated shampoos and proper sanitation. The user plans to see a dermatologist and is concerned about possible infection or allergic reaction.

Hair regrowth on wounded and bald skin may be possible by activating the sonic hedgehog gene, leading to hair regrowth in mice. The findings are promising but may not directly apply to humans.

Carnosic acid in rosemary extract may enhance skin repair and promote hair follicle regeneration. It could be used alone or with verteporfin for scarless healing after dermal wounding.

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.
