At six months, the group using the minoxidil solution showed a mean improvement in the anagen ratio of 11.68 percent, and the group of the caffeine solution had an anagen improvement of 10.59 percent.
The close-margin results suggest that a caffeine-based topical liquid should be considered as not “inferior” to a minoxidil solution in men with androgenetic alopecia, the researchers concluded.
It is important to note that not everyone is safe to take minoxidil.
“Minoxidil can also be used to treat female pattern baldness. Women should not use finasteride,” warns the NHS.
