If you are losing your hair and want it to stop, you have two treatments with strong evidence behind them: finasteride and minoxidil. That is it. Everything else you see advertised — laser caps, special shampoos, vitamin stacks, essential oils — has far less proof. This is not a matter of opinion. The FDA has approved finasteride and minoxidil for hair loss. No other treatment has that level of regulatory backing. If you want to stop going bald, those two drugs are where you start.
What Actually Causes Baldness in Men and Women?
Most hair loss in adults is androgenetic alopecia. That is the medical term for male or female pattern baldness. It is genetic. It is also driven by hormones — specifically a hormone called dihydrotestosterone, or DHT.
DHT is a byproduct of testosterone. An enzyme called 5-alpha-reductase converts some of your testosterone into DHT. In people with a genetic sensitivity, DHT attaches to hair follicle receptors and slowly shrinks them. Over time, the follicles produce thinner, shorter hairs until they stop producing hair entirely.
This process does not happen overnight. It takes years. That is why early treatment matters. Once a follicle is dead, no treatment brings it back. The goal of any hair loss treatment is to stop the shrinking process before the follicle dies.
Other causes of hair loss exist. Stress can trigger telogen effluvium, a temporary shedding phase. Thyroid issues, iron deficiency, and autoimmune conditions can also cause hair loss. But those are less common. If your hair is thinning gradually at the temples or crown, pattern baldness is the likely cause.
Does Finasteride Actually Stop Hair Loss?
Yes. Research shows finasteride stops hair loss in most men who take it consistently. The drug works by blocking the enzyme that converts testosterone into DHT. Lower DHT levels mean less damage to hair follicles.
A study published in the Journal of the American Academy of Dermatology followed men taking finasteride for five years. Over 90% of them maintained or increased their hair count compared to men taking a placebo. That is a strong result for a drug that costs about a dollar a day.
Finasteride is not approved for women of childbearing age. Pregnant women should not even handle crushed or broken tablets, as the drug can cause birth defects in male fetuses. For postmenopausal women, some dermatologists prescribe it off-label, but the evidence is weaker than in men.
The biggest concern with finasteride is side effects. About 1% to 2% of men report sexual side effects like reduced libido or erectile dysfunction. These usually go away after stopping the drug, though some men report persistent symptoms. That is rare but real. If you experience side effects, talk to your doctor. Do not just stop taking it without medical advice.
How To Stop Going Bald Treatments That Actually Work — Minoxidil
Minoxidil is the other FDA-approved treatment. You know it as Rogaine. It comes as a foam or liquid you apply directly to your scalp twice a day.
Unlike finasteride, which blocks DHT, minoxidil works by stimulating blood flow to hair follicles. It also extends the growth phase of the hair cycle. The exact mechanism is not fully understood, but the results are clear. Studies show minoxidil regrows hair in about 40% to 60% of people who use it consistently.
Minoxidil works for both men and women. Women should use the 2% strength unless a doctor recommends the 5% version. Men typically use 5%. It takes about four to six months to see results. You have to keep using it. If you stop, any hair you regrew will fall out within a few months.
A common mistake is stopping minoxidil too early. People try it for six weeks, see no change, and quit. That is not enough time. Hair grows in cycles. You need at least four months to judge whether it is working.
Side effects are mild. Some people get scalp irritation or unwanted hair growth on the face if the liquid drips. The foam version reduces this risk. If irritation persists, try switching to the foam or applying it less often.
What About Laser Caps, PRP, and Other Treatments?
You have probably seen ads for laser caps and helmets that claim to regrow hair using red light. The evidence here is weaker than the marketing suggests. Some small studies show low-level laser therapy may help with hair density, but the results are modest at best.
The American Academy of Dermatology says laser devices can be considered as an option, but they do not recommend them over finasteride or minoxidil. If you have money to burn and want to try everything, a laser cap is unlikely to hurt. But do not expect it to replace the drugs.
Platelet-rich plasma therapy, or PRP, is another popular option. A doctor draws your blood, spins it in a centrifuge to concentrate the platelets, and injects it into your scalp. The idea is that growth factors in the platelets stimulate hair follicles.
Some studies suggest PRP may help, especially when combined with finasteride or minoxidil. But the research is inconsistent. There is no standard protocol. Different clinics use different methods. Results vary widely. PRP is also expensive — typically several hundred dollars per session — and insurance does not cover it.
If you are considering PRP, look for a board-certified dermatologist who has done it many times. Ask how many sessions they recommend and what results their patients typically see. Be skeptical of clinics that promise dramatic regrowth.
Supplements like biotin, saw palmetto, and pumpkin seed oil are widely promoted for hair loss. The evidence is thin. Biotin only helps if you are actually deficient, which is rare. Saw palmetto may have a mild DHT-blocking effect, but it is far weaker than finasteride. If you want to try supplements, they are generally safe. Just do not expect them to stop balding on their own.
What to Avoid — Treatments That Do Not Work
A lot of products claim to stop hair loss with no evidence behind them. Scalp massagers, caffeine shampoos, and “hair growth” vitamins are the most common examples. They make money from hope, not results.
Caffeine shampoos are a good example. Some lab studies show caffeine can stimulate hair follicles in a petri dish. But no good clinical trial shows that washing your hair with a caffeine shampoo stops balding in real people. The caffeine does not stay on your scalp long enough to make a difference.
Hair growth vitamins often contain biotin, zinc, and various B vitamins. Unless you have a diagnosed deficiency, these will not help your hair. Your body gets rid of excess vitamins in your urine. You are essentially paying for expensive pee.
Scalp massagers and microneedling rollers are popular on social media. Microneedling actually has some evidence when done properly by a dermatologist. At-home rollers carry a risk of infection and scarring. Do not try this yourself. If you want microneedling, get it done in a medical setting.
Hair transplants are a real option, but they are surgery. A surgeon moves healthy hair follicles from the back of your scalp to thinning areas. The transplanted hair stays because those follicles are not sensitive to DHT. But transplants cost thousands of dollars, require recovery time, and do not stop existing hair from falling out. You still need finasteride or minoxidil to protect the hair you have left.
Comparison of FDA-Approved Treatments
| Treatment | How It Works | Evidence | Side Effects | Cost |
|---|---|---|---|---|
| Finasteride (pill) | Blocks DHT production | Strong — slows or stops loss in 90% of men | Sexual side effects in 1-2% of men | $10-30 per month |
| Minoxidil (topical) | Stimulates blood flow to follicles | Strong — regrows hair in 40-60% of users | Scalp irritation, facial hair growth if drips | $15-30 per month |
Both treatments work best when used together. Finasteride stops the damage. Minoxidil stimulates growth. Many dermatologists recommend combining them for the best results.
It takes time. You will not see changes in a month. Give it six months of consistent use before deciding whether it is working. Take photos every month under the same lighting. That is the only reliable way to track progress.
Frequently Asked Questions
Frequently Asked Questions
Can you regrow hair after balding?
You can regrow some hair if the follicle is still alive, but you cannot regrow hair from a completely dead follicle. Early treatment gives the best chance.
Does finasteride work for women?
Finasteride is not approved for women of childbearing age due to birth defect risks. Some postmenopausal women use it off-label with a doctor’s guidance.
How long does minoxidil take to work?
Most people see results after four to six months of consistent twice-daily use. You must keep using it or any regrown hair will fall out.
Is hair transplant better than medication?
A transplant replaces lost hair but does not stop further loss. You still need finasteride or minoxidil to protect remaining hair. Many people do both.
