[0002] The phenomenon of hair loss has evolved from a medical problem to a problem of social anxiety. To solve the problem of hair loss, people will resort to wearing wigs, but wearing wigs is stuffy and itchy, so people will grow hair. Topical drug therapy is the mainstream means of treating hair loss and promoting hair follicle activity. The topical agent minoxidil tincture achieves its therapeutic effect by stimulating hair follicle microcirculation and prolonging the hair growth period. Its effectiveness is highly dependent on direct contact between the drug and the scalp. Therefore, a double-nozzle sprayer for spraying drugs is needed to apply the drug.
