Yes, most people feel that hair shedding gets worse once they stop Minoxidil suddenly. It takes about 6-9 months to lose hair that you gain after using Minoxidil. Some people even see shedding after starting Minoxidil. Once you stop taking Minoxidil the blood flow to the follicles decreases and the anagen growth phase of hair starts getting shorter and the hair will grow thinner and eventually fall. However the hair shedding varies from person to person and could be temporary.
