Effects of Oral Minoxidil on Nails: A Cross-Sectional Analysis

Minoxidil was applied to a single miniaturized hair follicle over four months, resulting in less miniaturization but not yet terminal growth. The user used a 5% minoxidil solution, specifically the Regaine brand, and observed changes using a handheld WiFi microscope.

A 22-year-old male is switching from topical to oral minoxidil due to limited results with topical use, while continuing oral finasteride and considering side effects. Users discuss experiences with oral minoxidil, noting potential side effects like swelling and headaches, but also its effectiveness compared to topical treatments.

Oral minoxidil treatment increased hair density and shaft caliber in AGA patients. Side effects included hypertrichosis and lower extremity edema, with younger patients experiencing fewer side effects.

A 44-year-old man experienced significant hair regrowth after switching from topical to 1.25mg oral minoxidil and 0.5mg daily finasteride, with no side effects. He noticed hair thickening after two months and credits the oral form's effectiveness.

A person in their early 30s has been using finasteride for about 10 years and recently started oral minoxidil, vitamin chewables, and dermarolling to address hair loss. They noticed pigmented vellus hairs and potential regrowth, questioning if oral minoxidil is more effective than topical due to enzyme differences.

The user has been using oral minoxidil 2.5 mg for 9 months and oral finasteride 1 mg for 4 months, along with microneedling, and has noticed more baby hairs and longer eyelashes but no extra overall thickness. They are considering increasing the minoxidil dose but are concerned about safety due to potential side effects.
