Finasteride

Finasteride — Lowers DHT to Treat Male-Pattern Hair Thinning

Genetic hair thinning is something many men deal with, driven by DHT, which gradually weakens hair follicles. Finasteride is a tablet that blocks the enzyme converting testosterone into DHT, lowering DHT and slowing hair loss.

💊 Finasteride 1 mg comes in several brands — from the original Propecia and generic Finasteride to alternatives like Firide, Finascia, and Harifin.

Finasteride is a 5-alpha-reductase inhibitor for male-pattern hair thinning. It lowers DHT, the hormone that weakens hair follicles.

📊 Key facts about finasteride:

  • Blocks type II 5-alpha-reductase, lowering DHT
  • Needs 3-6 months of daily use for results; effects fade after stopping
  • Only 1 mg in stock, for hair thinning, not the 5 mg strength for an enlarged prostate

💊 Intimo Life carries finasteride 1 mg from Finasteride, Firide, Finascia, Harifin, and Propecia. Enlarged prostate? See our Enlarged Prostate Treatment collection.

  • New to hair thinning — the 1 mg daily dose fits
  • Enlarged prostate (BPH) needs 5 mg, which we do not stock
  • Women with hair loss should see our Female Hair Loss Treatment collection instead

⚠️ Always consult a pharmacist or doctor first. Women must not take finasteride, and women who are pregnant or may become pregnant must not handle broken or crushed tablets.

Understanding Finasteride

What Is Finasteride and How Does It Work

What Is Finasteride and How Does It Work

Finasteride is a type II 5-alpha-reductase inhibitor. It blocks the enzyme that converts testosterone into DHT, the hormone that shrinks hair follicles at the crown and hairline in men with genetic, androgenetic hair thinning. Lowering scalp DHT lets the growth cycle run longer, so finasteride treats the hormonal cause, not just the scalp surface like a shampoo or tonic. Results build up gradually, not overnight. Intimo Life carries finasteride at the 1 mg strength made for this use. You may also see it spelled "finesteride" — same medicine.

Finasteride 1 mg vs 5 mg — What's the Difference

Finasteride 1 mg vs 5 mg — What's the Difference

The difference is the use, not the drug. Finasteride 1 mg treats male-pattern hair thinning. Finasteride 5 mg treats benign prostatic hyperplasia (BPH), an enlarged prostate. Intimo Life stocks only the 1 mg strength, for hair thinning; we do not carry 5 mg. Looking for finasteride 5 mg for an enlarged prostate, or dealing with frequent urination or a weak stream? This page is not what you need — see our enlarged prostate treatment collection instead.

When and How to Take Finasteride

When and How to Take Finasteride

You can take it with or without food — there is no meal restriction. What matters more is a fixed daily time, for example right after brushing your teeth each morning, because consistency is what decides the result, not morning versus evening. Take one tablet daily as directed by your doctor or pharmacist. Do not break or crush the tablets, and keep them away from any woman in the household who is or may become pregnant. Missed a dose? Do not double up; just take the next one as scheduled.

How Long Until It Works, and What Happens If You Stop

How Long Until It Works, and What Happens If You Stop

Expect at least 3 months of daily use before any change, with the fuller effect usually showing after 6 to 12 months of continuous use. This is a long-term medication, not a short course, and it does not guarantee regrowth for everyone — results vary. If you stop, scalp DHT rises back to its previous level, and any regrowth gained is typically lost again within about a year. Staying on it maintains the result.

Finasteride Side Effects

Finasteride Side Effects

Uncommon but real, and worth knowing before you start — not to alarm you, but not to gloss over either. Reported effects include reduced sex drive, difficulty getting or keeping an erection, reduced semen volume or difficulty ejaculating, and breast tenderness or enlargement. Most resolve after stopping, though a small number of people report symptoms that continue afterward. Notice any of these, or an unusual low mood? Talk to a pharmacist or doctor before deciding whether to continue.

Who Should Not Take Finasteride

Who Should Not Take Finasteride

Women must not take finasteride at all, including anyone who is or may become pregnant — it is never an option for female hair loss. Women who are pregnant or may become pregnant must never handle broken or crushed tablets — the drug absorbs through skin and may harm the genital development of a male fetus. One more thing: finasteride lowers PSA readings below their true level. Due for a prostate cancer screening, always tell your doctor you take finasteride so the result is read correctly.

Comparing the Finasteride Brands at Intimo Life, Plus Dutasteride and Minoxidil

Comparing the Finasteride Brands at Intimo Life, Plus Dutasteride and Minoxidil

Every brand below is the same drug — finasteride 1 mg — just a different manufacturer. Best brand comes down to budget and availability, not effectiveness. Check each product page for the current price, since prices change.

Dutasteride vs finasteride: dutasteride blocks type I and type II 5-alpha-reductase, lowering DHT further in theory, but has less long-term evidence than finasteride; Intimo Life does not carry it. Reten Five (minoxidil 5%) is topical, a different mechanism entirely — it stimulates blood flow to the follicle, unrelated to DHT, and can be used alongside finasteride. Nizoral shampoo (ketoconazole) is an antifungal shampoo, not a hair-thinning treatment, and contains no finasteride.

Frequently Asked Questions

You can buy Finasteride 1 mg from Intimo Life online. A pharmacist reviews your health details before every order ships, so no hospital visit is needed. We stock several brands — the full range is in the product list on this page. Tell the pharmacist about any existing conditions or other medicines before ordering, and ask if anything about the dose or how to take it is unclear.

Every finasteride brand Intimo Life stocks contains the same drug at the same 1 mg strength. The only differences are manufacturer and price, not the drug itself, so no brand is medically "better." Choose Finasteride (generic), Firide, Finascia, Harifin, or Propecia, the original brand. Check each product page for current pricing.

Take one 1 mg tablet a day, any time that suits you, with or without food, but try to keep it around the same time daily for steady drug levels. Swallow it whole with water, never break or crush it. Results take several months of continuous use to appear, and you must keep taking it, because hair loss returns once you stop.

Missing a day does not mean doubling up to two tablets the next day, just take the next one at your usual time. Finasteride's suppression of DHT carries over, so one missed dose will not undo your results right away. Missing doses often, or stopping altogether, lets DHT rise again, and hair loss gradually returns over the following months. Ask a pharmacist if you're unsure.

Sexual side effects are real but uncommon: reduced sex drive, difficulty getting or keeping an erection, and reduced semen volume. Some men also notice breast tenderness or enlargement. These usually improve after stopping the medicine. Talk to a pharmacist or doctor right away if you notice anything unusual or feel low in mood.

Women must not take finasteride, especially those who are or may become pregnant, since it can cause abnormal genital development in a male fetus. They must also avoid touching broken or crushed tablets. If you're a woman with thinning hair, see our hair loss treatment for women collection instead, which uses ingredients suited to women.

Yes, they work through different mechanisms. Finasteride is a tablet that lowers DHT from inside the body, while minoxidil (Reten-Five) is a topical solution applied to the scalp to improve blood flow to hair follicles. Many people use both to boost results, applying it before or after the tablet with no waiting needed. See a pharmacist if the scalp becomes irritated.

Finasteride blocks only type II 5-alpha-reductase; dutasteride blocks both type I and type II, so it lowers DHT more in theory, but that also means more potential side effects and a drug that stays in the body far longer. Dutasteride is not formally approved for hair loss in many countries, unlike finasteride, which is far more widely used for this purpose. Intimo Life does not currently sell dutasteride.
