No treatment for hair loss is instantly successful, and Minoxidil is no exception. So, expect to see a difference to your hairline after 3-6 months of continuous use. Whilst for some it can be longer, for others the timelines can be much shorter. Every man is different. Yet, there is one thing true for us all: to tackle balding, you need continuous treatment. If you stop using Minoxidil, MPB will return.
