Search for hair loss treatment and you will find hundreds of products, many with big promises and little evidence. This guide focuses on the options with the most research behind them, what each one is, and the limits of that evidence, so you can have a better-informed conversation with a provider.
Start with the cause
The right treatment depends on the type of hair loss. The most common is pattern hair loss (androgenetic alopecia), which is gradual and hereditary. Others include stress-related shedding (telogen effluvium), thyroid and nutrition-related thinning, alopecia areata, and hair loss from tight hairstyles. These respond to different approaches, so a diagnosis comes first. See telogen effluvium vs androgenetic alopecia.
Options with the strongest evidence for pattern hair loss
Minoxidil
Topical minoxidil is available over the counter and is FDA-approved for hereditary hair loss in men and women. It is thought to act on the hair growth cycle and follicle blood flow. Oral minoxidil is a prescription blood pressure medication that providers sometimes prescribe off-label for hair loss. See topical vs oral minoxidil.
Finasteride
Oral finasteride is FDA-approved for male pattern hair loss. It lowers DHT, the hormone that drives follicle shrinkage. It requires a prescription and is not appropriate for anyone who is or may become pregnant. See does finasteride work for a receding hairline.
Options with supporting but more limited evidence
- Dutasteride, a broader DHT blocker used off-label for hair loss in the US.
- Spironolactone, an anti-androgen used off-label for female pattern hair loss.
- Low-level laser devices, some of which are FDA-cleared for hair loss.
- Platelet-rich plasma (PRP), an in-office procedure with mixed study results.
- Hair transplant surgery, which moves existing follicles and does not stop ongoing loss elsewhere.
Options with weak or early evidence
Many ingredients, including latanoprost, melatonin and various botanicals, have small or early studies. They may be considered as part of a combined plan, but the evidence does not support them as stand-alone treatments. Be cautious of any product promising guaranteed or fast results.
Combined and compounded approaches
Providers sometimes prescribe a compounded topical formula combining ingredients, for example minoxidil with a DHT blocker. Compounded medications are prepared by a licensed pharmacy for an individual patient and are not FDA-approved. Whether a combined approach makes sense is a clinical decision. See compounded vs over-the-counter treatment.
Setting realistic expectations
For pattern hair loss, the most consistent benefit of treatment is slowing or stopping further loss. Some people also see partial regrowth, but responses vary widely and no treatment works for everyone. Hair changes slowly, so providers typically evaluate response over months rather than weeks, and most treatments only work while they are continued.
