Topical Solution 5% is a hair re-growth treatment for men ex-periencing hair loss or thin- ning. It contains 5% minoxidil, the #1 dermatologist-recommended active in- gredient for hair regrowth. This solution is de- signed to be applied directly to the scalp, stimulating hair follicles and potentially thick- ening hair. It's often used to address male pat- tern baldness (androgenetic alopecia).
