TLDR Low-dose oral minoxidil may cause side effects like hypertrichosis and is not suitable for everyone.
The study examined the adverse effects of low-dose oral minoxidil for androgenetic alopecia in 435 patients. The most common adverse effect reported was hypertrichosis, which was associated with younger age and dose/weight in men. Other adverse effects included hypotension, tachycardia, edema, headache, insomnia, and nightmares. The study suggests that low-dose oral minoxidil may not be suitable for all patients with androgenetic alopecia due to the potential for adverse effects.
