Onychomatricoma in the Light of the Microanatomy of the Normal Nail Unit

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.

MCL-1 protein may help maintain hair follicles in the growth phase and prevent miniaturization. There is interest in experimental treatments like exosomes, peptides, or stem cell serums to upregulate MCL-1 for hair loss, especially for those not using minoxidil or finasteride.

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.

The user has been microneedling at 0.25mm once a week for 4 weeks and noticed further hairline recession. They are concerned about the impact of vitamin deficiencies, like biotin, on hair growth.

The user has been using finasteride for 16 months, minoxidil for 11 months, and started microneedling 2 months ago, experiencing shedding phases. They are questioning whether they are experiencing miniaturization or regrowth.

The user experienced hairline improvement using microneedling once a month with a 12-pin set at 1.5-2.0mm and taking Tru Niagen, alongside a heavily modified diet. They attribute the slow hairline improvement to environmental factors, particularly diet, rather than solely genetic factors.
