usually tugain gel (minoxidil) is prescribed for Hair loss. There are no specific side effects in females. The only documented side effect is interestingly also the hair loss. Since this drug enhances the nutrition to the hair, this also enhances the activity of hair follicles which are in dying phase. But in young people like you the hair follicles in dying phase are very less. thus the benefit is high compared to the risk, thus i would recommend not to worry about the sideeffects.
