What is the best treatment for hair loss?

The best treatment for hair loss is usually a combination, not a single product. Most pattern hair loss is driven by the hormone DHT slowly shrinking the follicle, so the plans that work do three things at once: block DHT, stimulate new growth, and regenerate the follicle. The best-documented results come from pairing a DHT blocker with minoxidil, often layered with PRP, with options ranging from natural (saw palmetto) to prescription (finasteride and minoxidil).

This applies to both men and women, but the approach is not identical for each. Female pattern hair loss looks different, has different common causes, and calls for different tools, so if you are a woman, read the general framework below and then the section written specifically for you.

In my more than 20 years in medicine, hair loss is one of the areas where people waste the most money on the wrong single product bought online, when a thoughtful combination managed by a physician would have actually moved the needle. So let me walk you through what each tool does, honestly, and how they fit together.

First, the cause: DHT

The most common type of hair loss in both men and women is androgenetic alopecia, or pattern hair loss. In people who are genetically susceptible, a hormone called DHT (dihydrotestosterone) gradually miniaturizes the follicle, cycle after cycle, until the hair grows back thinner and shorter and eventually not at all. That is why an effective plan usually attacks the problem from more than one angle at the same time: reduce the DHT shrinking the follicle, push the follicle back into a growth phase, and give it the support to rebuild.

Job one: block the DHT

Natural DHT blockers. Saw palmetto is the most-studied natural option, working by gently inhibiting the enzyme that makes DHT. In one small study, about 60 percent of men saw improvement versus 11 percent on placebo, and over longer use it tends to stabilize hair loss more than dramatically regrow it. It is gentler than prescription options, with fewer sexual side effects, which is why some people prefer to start here. Pumpkin seed oil has similar support, with one study showing a 40 percent increase in hair count over six months. One important point on how you get these: supplements are poorly standardized, so with a store-bought bottle you often cannot be sure it actually contains what the label claims. That is why we provide these through our office as a proven, professional-grade product, rather than sending you to guess on a store shelf. And one honest caveat with saw palmetto: because it lowers DHT, it can also lower your PSA reading, the blood test used to screen for prostate cancer, so your doctor needs to know you are taking it.

Finasteride (prescription). Finasteride is the heavyweight DHT blocker. It reduces DHT far more powerfully than any natural option, roughly 70 percent, and the evidence for slowing loss and regrowing hair is strong. It is a prescription for a reason: it requires evaluation, and it is not right for everyone. Some men experience sexual side effects, and it is strictly off-limits for women who are pregnant or may become pregnant, because it can cause birth defects. For the right patient, it is one of the most effective tools we have. As you will see below, women who need an anti-androgen usually reach for spironolactone instead.

Job two: grow the hair (minoxidil)

Minoxidil is the growth driver, and it works differently than the DHT blockers. Most of its effect is independent of hormones. It reawakens resting follicles, pushes them into the active growth phase, keeps them growing longer, and improves the blood flow and growth signals reaching the follicle. Newer research shows minoxidil also has a mild anti-androgen effect of its own, a small bonus on top of its main job.

Minoxidil comes in a few forms, and the right one depends on you. There is the familiar topical solution and foam, and there is low-dose oral minoxidil, which has become popular because it is simple and consistent. The oral form is a prescription and needs a quick check of your blood pressure and heart rate up front and along the way. Whichever form you use, one rule holds: minoxidil works only as long as you keep using it. Stop, and the gains fade over the following months. That is not a flaw, it is simply how it works, and it is why we build it into a plan you can actually maintain.

Job three: regenerate the follicle (PRP)

PRP, or platelet-rich plasma, is the regenerative layer. We draw a small amount of your own blood, concentrate the platelets and the growth factors they carry, and inject that concentrate into the scalp to wake up and strengthen the follicles. A large 2025 analysis of dozens of trials found PRP increases hair density and thickness in pattern hair loss, using nothing but your own biology. It works best as a series of sessions with periodic maintenance, and it pairs especially well with the treatments above. Two honest points: because it uses your blood, it must be done in a proper medical setting with sterile technique, and it cannot bring back follicles from an area that has gone completely bald. You can read more on our page about whether PRP works for hair loss.

The winning move: combination formulas

Here is the part that matters most. No single treatment above is the answer by itself. The strongest, best-documented result in all of hair loss is a DHT blocker plus minoxidil: recent analyses support that finasteride plus minoxidil beats minoxidil alone on hair density, thickness, and overall appearance, and combining minoxidil with an anti-androgen consistently ranks among the most effective approaches available. Block and grow at the same time, and you get more than either one alone.

That principle drives how we actually build a plan. We can combine minoxidil and finasteride into a single compounded topical solution, so you block DHT and stimulate growth in one step applied to the scalp, often layered with microneedling or PRP to drive it deeper. For patients who want to avoid finasteride, pairing a natural DHT blocker like saw palmetto or pumpkin seed oil with topical or low-dose oral minoxidil is a reasonable, gentler combination, with expectations set honestly since the evidence is weaker. Rosemary oil is another natural option with some supporting evidence, though gentler and less proven than the mainstays. And a PRP series on top of a block-and-grow routine adds regenerative support the topicals and pills cannot provide on their own.

Treatment	Its job	How you take it	Worth knowing
Saw palmetto / pumpkin seed oil	Block DHT (mild)	Provided by our office (standardized, not OTC)	Gentler, weaker evidence; saw palmetto can lower PSA
Finasteride	Block DHT (strong)	Oral or compounded topical, prescription	Potent; not for women who may become pregnant
Minoxidil	Grow hair	Topical, or low-dose oral	Must keep using it; oral needs monitoring
PRP	Regenerate the follicle	In-office injections, a series	Your own biology; cannot revive fully bald areas
Compounded / combination	Block + grow together	One topical formula, often with PRP	The best-documented results come from combining

Hair loss in women is different

Everything above applies to women too, but female pattern hair loss does not look or behave the way it does in men, and it deserves its own approach. Women rarely get a receding hairline or a bald crown. Instead the hair thins diffusely across the top of the scalp, the part slowly widens, and the ponytail gets thinner, while the front hairline usually holds. It is incredibly common, especially around perimenopause and menopause, and it is one of the most distressing things I watch women go through. The good news is that it is treatable, and often very treatable.

For women, rule out the fixable causes first

This is where women’s hair loss differs most, and where having a physician actually matters. Before reaching for any hair product, a proper workup looks for the reversible drivers, because in women a surprising amount of hair loss is being caused or worsened by something we can simply correct. That list includes thyroid problems, low iron (your ferritin level specifically), the hormonal shifts of perimenopause and menopause, PCOS, postpartum shedding, high stress, rapid weight loss, and certain medications. Treat the underlying driver and the hair often recovers without anything elaborate. That workup is standard for us, and it is exactly the step that gets skipped when hair loss is treated as a product to sell instead of a symptom to understand.

Because so much of women’s hair loss traces back to hormones, this is often connected to the bigger picture of how you are feeling overall. Our pages on menopause and the signs you may need hormone support are worth a look if your thinning arrived alongside changes in energy, sleep, mood, or cycle.

What actually works for women

Once the fixable causes are addressed, the treatments that carry real evidence for women are minoxidil, spironolactone, and PRP. Minoxidil is first-line and works the same way it does for anyone, most often as a topical or low-dose oral with the same monitoring. PRP adds the regenerative layer. The piece that is specific to women is spironolactone.

Spironolactone is the anti-androgen with the real track record in women. It is essentially the female counterpart to finasteride, but it works by a different route: it blocks androgens at the follicle and tamps down androgen production, so it takes the DHT pressure off your hair. At an effective dose it has been shown to halt the loss and bring partial regrowth for many women. It can be taken orally, used as a topical, or combined at a low dose with minoxidil in a single formula so you block and grow in one step. It does require a physician, because it can cause breast tenderness, changes in your cycle, and it affects your potassium level, so it calls for a quick lab check and periodic monitoring. This is the tool that most often takes finasteride’s place for women, since finasteride is generally avoided in any woman who could become pregnant.

One honest word on the supplements marketed to women. You will see natural “DHT-blocking” pills sold hard for female hair loss, and I want to save you money: some, like DIM, have a mechanism that looks plausible on paper but have no real clinical evidence for hair loss, so I do not want you buying them expecting a fix. Spironolactone and minoxidil are where the evidence actually sits. Finasteride can occasionally be used in specific postmenopausal cases, but it is not the default for women the way it is for men.

For women	Its job	How you take it	Worth knowing
Treating the root cause	Fix what is driving it	Labs plus targeted treatment	Thyroid, iron, hormones; often reverses the loss on its own
Minoxidil	Grow hair	Topical, or low-dose oral	First-line for women; must keep using it
Spironolactone	Block androgens	Oral, topical, or low-dose combo with minoxidil	The anti-androgen of choice for women; needs monitoring
PRP	Regenerate the follicle	In-office injections, a series	Your own biology; pairs well with the above

An honest word before you start

Results vary from person to person, no treatment is a guarantee, and earlier is always better than later, because it is far easier to keep the hair you have than to regrow what is gone. Prescription options require an evaluation and monitoring, not a checkout cart, and I would steer you away from the random hair-growth formulas sold online, both for safety and because the right combination for you is not one-size-fits-all. What works is matching the tools to your pattern, your goals, and how much intervention you are comfortable with.

The next step

If your hair is thinning and you are tired of guessing, the smart move is a consult where we look at your scalp, your goals, and your comfort level, and build a combination plan around blocking, growing, and regenerating, from natural to prescription to PRP. For women, that starts with the labs to catch anything reversible before we go further. You will leave knowing exactly what your options are and what to realistically expect.
