TLDR Higher minoxidil concentration (5%) works better for severe hair loss, with most patients seeing regrowth in 48-60 weeks.
The study found that a 5% topical minoxidil solution was significantly more effective than a 1% solution in treating severe alopecia areata, with 85% of patients experiencing hair regrowth after 48 to 60 weeks of treatment. The study suggests that exploring modifications in dosing and delivery systems may enhance therapeutic efficacy.
