What Is Finasteride and How Does It Block DHT?
Finasteride is a man-made drug that stops the major enzyme (type II 5-alpha-reductase) from turning testosterone into DHT, a stronger hormone, in hair roots and the prostate. Taking 1 mg a day lowers DHT in the scalp by about two-thirds and elevates testosterone by around 15 percent because the body creates a little more testosterone when DHT levels go down.
About 63% of each pill gets into the blood, and the greatest amount of the drug in the blood is about two hours after taking it. For most individuals, the medication leaves the body in five to six hours. For older males, it takes closer to eight hours. With one pill a day, blood levels even out after a week, and beneficial amounts build up in the scalp in around four weeks.
| Pharmacological Parameter | Finasteride 1 mg Daily | Clinical Relevance |
|---|---|---|
| Scalp DHT Suppression | 64–69% | Sufficient for follicular recovery without systemic compromise |
| Serum DHT Reduction | 71% | Maintains androgenic function while blocking follicular miniaturization |
| Hair Count Increase (vertex) | +17% at 24 months | Mean 107 hairs/in² improvement from baseline |
| Responder Rate | 83% at 2 years | Defined as maintenance or improvement versus baseline |
| Treatment Failure Rate | 17% at 2 years | Continued progression despite compliant use |
How Quickly Does Finasteride Work? Month-by-Month Results
The five-year Finasteride Male Pattern Hair Loss Study Group data gives the dates for when results are predicted to happen. The first response patterns follow certain phases that are determined on how follicles cycle:
- Months 0–3: 10–15% of patients have telogen effluvium as their hair follicles start to grow at the same time. The average daily shedding goes up from 100–150 hairs to 200–300 hairs for a short time.
- Months 3 to 6: 83% of the people who were studied saw their shedding return to normal. Measurements of hair mass suggest that it has stabilized, and 42% of people said they felt that coverage had improved.
- Months 6 to 12: The average number of hairs in the target area goes up by 11% (from 3% to 18%). Photographic assessment shows that 48% of patients have become better.
- Months 12 to 24: The most therapeutic impact was seen, with 65% of patients having thicker hair, 31% staying the same, and 4% losing more hair.
Long-term extension studies show that 90% of improvements are still there after 5 years. However, 16% of people see a steady loss in effectiveness after year 5, which may be due to age-related androgen receptor upregulation.
Is Finasteride Safe—and Who Should Avoid It?
The Prostate Cancer Prevention Trial, which involved 18,882 men, gives complete safety data for seven years. The medicine obviously caused side effects like diminished sex drive (1.8% compared to 1.3% with dummy pills), trouble getting erections (1.3% compared to 0.7%), and fewer semen volume (0.8% compared to 0.4%). Mella et al. (2010) did a big study that showed these effects go away in 95% of males within three months of quitting the medication.
Finasteride cuts PSA (a blood test used to find prostate cancer) levels in half after 12 months of treatment, therefore doctors need to change how they read test findings. If your PSA levels go up while you're getting treatment, you need to see a urologist right away because this could mean you have cancer.
Some people have reported having negative effects that lasted after they stopped using finasteride, however controlled medical studies have not been able to establish this. In 2022, the International Society of Hair Restoration Surgery (a group of medical professionals) said that there is no confirmed link between the two, but they also said that more research is needed.
Can Women Use Finasteride Off-Label?
Finasteride is under Pregnancy Category X by the FDA because it can cause problems with the external genitals in male babies that are exposed to it between weeks 8 and 12 of pregnancy. Women who could get pregnant need to have a negative pregnancy test and solid birth control that works 98% of the time, either an IUD, an implant, or a combination of the two.
According to Thai et al. (2021), postmenopausal women show 37–54% improvement rates when they take 1–5 mg of the drug every day. There is still debate over the ideal dose, however 2.5 mg seems to have the best balance of effectiveness and adverse effects. Adding spironolactone 100–200 mg to the treatment helps hyperandrogenic patients respond better.
Finasteride vs. Dutasteride vs. Minoxidil: Which Is Best?
Direct comparative studies and network meta-analyses show how effective FDA-approved and off-label medicines are compared to each other:
| Treatment | Mechanism | DHT Suppression | Hair Count Increase | Adverse Event Rate |
|---|---|---|---|---|
| Finasteride 1mg | Type II 5AR inhibition | 69% scalp | +17% at 24 months | 4.2% sexual |
| Dutasteride 0.5mg | Type I+II 5AR inhibition | 51% scalp (Type I), 79% (Type II) | +23% at 24 months | 6.1% sexual |
| Minoxidil 5% bid | Potassium channel opener | None | +13% at 16 weeks | 6% contact dermatitis |
| Topical Finasteride 0.25% | Local 5AR inhibition | 43% scalp, 24% serum | +15% at 24 months | 1.8% sexual |
Finasteride monotherapy is the best first-line treatment for quickly stabilizing hairlines. Adding minoxidil helps people who don't respond after 12 months (94% of people who use the two medications together report a synergistic effect). Dutasteride is only used when finasteride fails because it has a higher risk of side effects.
Daily Dose, Lab Monitoring, and Lifestyle Checklist
Standard protocol: Take 1 mg by mouth once a day, with or without meals. No need to change the dose for older people or people with kidney problems. When you split 5 mg tablets (Proscar) into four pieces, you save money. Studies show that the four pieces are bioequivalent when done correctly.
Men over 40 need to have their baseline PSA checked every year (with values doubled for interpretation), and men on hepatotoxic drugs need to have their liver function tested. Men with poor response at 12 months simply need to have their testosterone and DHT levels checked. Optimizing your lifestyle can improve your health. For example, you should eat between 1.2 and 1.6 grams of protein per kilogram of body weight, have ferritin levels over 70 ng/mL, vitamin D levels above 30 ng/mL, and use proven methods to lower your stress.
Finasteride Cost—Ways to Save
Prices in the US right now range from $8 to $85 a month, depending on the source and the formulation:
- Generic finasteride 1 mg costs $25–$45 at CVS, Walgreens, and Walmart, but drops to $8–$15 with GoodRx.
- Quartering a Proscar 5 mg generic tablet costs $7–$12 per month, though careful pill-cutting is essential.
- Costco and Amazon Pharmacy ship a 90-day supply for $20–$35.
- Telemedicine platforms — Keeps, Hims, and Roman — charge roughly $20–$30 per online visit.
- Compounded topical formulas aren’t covered by insurance and typically run $45–$80.
Most insurance plans don't cover cosmetic procedures, but some do. HSA/FSA funds can be used if a doctor says they are medically necessary.
How to Buy Finasteride Online Without Getting Scammed?
There are two basic ways to get finasteride. The usual way is to go to the doctor's office, get a paper prescription, and then go to a real drugstore. You can talk to both the doctor and the pharmacist in person this way, but it also means taking time off work, paying more for things on the shelf, and feeling weird when you tell the cashier you need a prescription for hair loss.
The digital way starts with filling out a short health questionnaire and uploading a set of scalp images to a licensed online pharmacy.A doctor who is licensed in your state looks over the information the same day and, if everything seems good, sends an electronic prescription to a recognized U.S. pharmacy. You will get the medicine in a plain box within 48 hours.
A lot of people like the online option better because it doesn't have the stigma of going to a pharmacy, it tells you the exact price up front, and it gives you automatic reminders for every prescription. Legitimate services have a VIPPS seal, list the doctor's NPI number, and work with pharmacies that you can check on the NABP database. This gives users a straightforward way to confirm credentials before they buy.
Expert Tip — Dr. Angela Thompson, MD, Hair-Loss Specialist: “"Always check the doctor's license on your state medical board's website and the pharmacy's NABP number on the VIPPS checker." Close the tab if a website asks for cryptocurrencies or sells a month's worth of finasteride for less than eight dollars. Independent lab testing show that four out of ten ultra-cheap imports have the wrong strength or no active component at all.”
Expert Tip: Track Progress and Beat Plateaus
Standardized photography protocol: hair must be wet, fluorescent lights must be on, and the camera must be 12 inches away at the same angles every month. Global photographic examination every six months gives an objective measurement. Digital trichoscopy apps measure changes in hair density that are too small to see with the naked eye.
After 24 to 36 months of plateau management, you can add minoxidil 5% twice a day (which improves the condition by 38%), switch to dutasteride 0.5mg (which needs a titration period), microneedling 1.5mm once a week (which makes the drug penetrate 3 to 4 times better), or use adjuvant therapies like platelet-rich plasma injections every three months or low-level laser therapy at a 655nm wavelength.
Finasteride Side-Effect FAQs
Does using finasteride make you ineligible to donate blood?
The American Red Cross requires a 30-day washout after the last dose to prevent fetal exposure through transfusion. Schedule any donation around that window or wait until treatment ends.
Will finasteride affect how well you play sports or how much muscle you have?
Although serum testosterone rises about fifteen percent, studies show no change in lean mass, VO2 max, or strength tests. WADA permits finasteride, but athletes may need proof of medical use if their testosterone : epitestosterone ratio flags a review.
Can drinking alcohol make finasteride less effective?
Finasteride and ethanol are metabolized by different liver pathways, so they do not blunt each other. Heavy alcohol use can still impair overall liver function, which may slow the clearance of any medication.
What is the real risk of gynecomastia?
Clinical trials report gynecomastia in about 0.4 percent of users, usually within the first year. Most cases resolve within six months after stopping the drug; persistent enlargement warrants an endocrine work-up.
Key Takeaways and When to See a Dermatologist
Finasteride is the first drug that doctors use to treat androgenetic alopecia. There is Level 1A confirmation that it helps and is safe. The fact that it costs less than $30 a month and has an 83% response rate after 24 months suggests that it is more cost-effective than alternative treatments. 95% of the time, bad things that happen to 4.2% of users go away when they quit using the product.
You should see a dermatologist if you are losing more than 200 hairs a day (which could mean telogen effluvium or something else), have focal alopecia with preserved follicular ostia (alopecia areata), have scarring or inflammatory changes (which need a biopsy), or have treatment failure after 12 months even though you are following the rules.
You need to have reasonable expectations if you want your treatment to work. For instance, maintenance is a success since it is a natural process, apparent regrowth develops in just a few cases, and long-term benefits need a lifetime commitment. Adding minoxidil to combination treatments increases the response rate to 94%. Procedural procedures help with cases that don't respond to other treatments. Standardized photography lets you objectively judge and quickly alter processes by preserving accurate records.
