While Nanoxidil appears to lead to new hair growth in the medium- and long-term, the current research doesn’t explore the link between Nanoxidil and temporary short-term hair shedding. However, it’s possible that using Nanoxidil will lead to some initial hair shedding. Effective hair loss treatments typically expand the growth phase of the hair growth cycle, leading to a shorter telogen (resting) phase which brings about the exogen (shedding) phase more quickly. That’s why Minoxidil shedding and Finasteride shedding are common side effects of these treatments. Even if Nanoxidil does cause hair shedding, this is likely to be temporary. Visible hair regrowth is possible within just three months.
