Incidental Merkel Cell Carcinoma Encountered During Mohs Surgery

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.

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.

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.

The conversation discusses the steps for microneedling, specifically differentiating between medical needling (0.5-1.5mm) and cosmetic needling (0.3mm). It emphasizes the importance of cleaning and disinfecting before microneedling, regardless of needle length.

A user experienced significant hair loss after starting microneedling, despite using dutasteride and topical minoxidil. They are advised to consult a doctor as the shedding pattern is unusual and may indicate alopecia areata or other scalp conditions.

A user noticed irregularities on their scalp using a digital microscope and suspects scarring alopecia, despite using minoxidil and finasteride. Other users suggest seborrheic dermatitis as a possible cause and recommend treatments like ketoconazole shampoo, sulfur soap, selenium sulfide shampoo, and apple cider vinegar rinses.
