What is Hims hair spray and how does it work?

Hims hair spray is a topical solution designed for men to address hair thinning and loss. The active ingredient in most variants of Hims hair spray is minoxidil, which is an FDA-approved medication for the treatment of male pattern baldness. Minoxidil works by dilating the blood vessels in the scalp, which can improve hair follicle function and stimulate hair growth. It prolongs the anagen phase (growth phase) of the hair cycle and can revive shrunken follicles, ultimately increasing their size and helping to regrow thicker hair over time. The product typically needs to be used consistently, as directed, usually sprayed directly onto the scalp twice daily, for best results. Users may need to continue using the treatment to maintain any new hair growth, and it may take several months before they see significant improvements.
