    TLDR Minoxidil use can cause trichostasis spinulosa in long-term hair loss patients.
    The article reports a case of trichostasis spinulosa of the terminal hair type in a 35-year-old woman with female pattern hair loss who had been using topical minoxidil for 13 years. Trichostasis spinulosa is a follicular disorder resulting from the retention of numerous hairs surrounded by a keratinous sheath in a dilated follicle. The article emphasizes the importance of recognizing this disorder in patients with hair loss who have been using minoxidil for a long time. The case is unique because it was induced by minoxidil, a trichotrophic agent that transforms vellus hairs to terminal hairs.
