    TLDR Isotretinoin may cause temporary, reversible facial hair growth in some women.
    The study investigated the occurrence of facial hypertrichosis in 30 premenopausal female patients with acne vulgaris during and after isotretinoin treatment. With a mean therapy duration of 6.2±0.6 months, facial hair growth was observed in 10% of the patients, although it resolved spontaneously within 1-3 months post-treatment. The study suggests that isotretinoin may cause temporary hormonal imbalances leading to hair growth in susceptible individuals, but acknowledges that the exact mechanism is unclear. Despite the small sample size and lack of a control group, the findings indicate that the hypertrichosis side effect is reversible and further research is needed to understand the drug's impact on hair growth. The study recommends endocrinological and psychological assessments for patients undergoing isotretinoin therapy.

      High-dose oral minoxidil (>5 mg/day) can increase hair density in some men with androgenetic alopecia, but side effects like extra body hair and heart issues are common. Gradual dose increase is advised, but adverse effects may lead to discontinuation or dose adjustments.
