What is Harifin?
Harifin is a Finasteride 1mg tablet, a 5-alpha reductase inhibitor for male pattern hair loss (androgenetic alopecia). It reduces conversion of testosterone into DHT, the hormone that shrinks hair follicles over time. Take one tablet daily, at the same time, continuously. Results typically appear after 3 to 6 months — Harifin is made by T.O. Pharma, a Thai brand and another option in our Finasteride lineup.

Product Description
A hair loss treatment, Harifin is a Finasteride 1 mg oral tablet for male pattern hair loss (androgenetic alopecia) caused by genetics. It inhibits 5-alpha reductase, blocking testosterone's conversion into DHT — the hormone that shrinks hair follicles over time. Harifin is another Finasteride option from T.O. Pharma, a Thai brand, priced to be budget-friendly for men managing hair loss.

Root-cause mechanism — Finasteride blocks type II and III 5-alpha reductase, the enzymes converting testosterone into DHT (StatPearls — Finasteride)
Time to results — at least 3 to 6 months of continuous use before hair loss visibly slows (MedlinePlus)

About Harifin
What is Harifin and How Does It Work?
Harifin is a Finasteride 1mg tablet made by T.O. Pharma (T.O. Chemicals), a Thai pharmaceutical company, in the 5-alpha reductase inhibitor drug class.
It works by blocking type II and III 5-alpha reductase, the enzymes that normally convert testosterone into dihydrotestosterone (DHT). As scalp DHT levels drop, hair follicles that had been shrinking under DHT's influence gradually recover, growth cycles lengthen, and hair loss slows — with some regrowth possible in certain men.
Harifin uses the same generic Finasteride as branded originals, a way to start treating genetic hair loss without overpaying.
What Hair Loss Does Harifin Treat, and Who Is It For?
Harifin treats genetic male pattern hair loss (androgenetic alopecia), the most common cause of hair loss in adult men — typically starting as thinning at the crown (vertex) and frontotemporal hairline, progressing with age.
It suits men who notice early thinning, unusually heavy shedding, or a family history of male pattern baldness — starting treatment early helps preserve more of the existing hair.
Harifin is not suited for hair loss from other causes, such as fungal infection, thyroid disorders, or acute stress (telogen effluvium), which need separate, cause-specific treatment.
How to Take Harifin Correctly / Recommended Dosage
Dosage: Take one tablet (Finasteride 1mg) once daily, at the same time each day, without skipping.
It can be taken with or without food — absorption is unaffected. What matters most is daily consistency, since a steady blood level affects effectiveness more than any other factor.
Continuous use for at least 3 to 6 months is needed before results become clear, and ongoing use maintains them — stopping causes hair loss to gradually return within months.
What Are the Side Effects of Harifin, and How Common Are They?
Harifin is considered safe when used as directed. Side effects affecting more than 1 in 100 people include reduced sex drive, erectile difficulties, and reduced semen volume. These usually improve with continued use and often resolve after stopping, though a small number of men report symptoms that persist.
Side effects affecting fewer than 1 in 1,000 people include low mood or thoughts of self-harm — stop immediately and see a doctor if this occurs — along with breast enlargement, lumps, or nipple discharge, which are rare but warrant prompt medical attention.
For a severe allergic reaction — rash, facial or throat swelling, difficulty breathing — stop Harifin and seek emergency care immediately.
Contraindications & Precautions for Harifin
Contraindications:
Never use in women under any circumstances, especially those who are or may become pregnant — Finasteride can cause genital abnormalities in a male fetus
Not for use in children, or anyone allergic to Finasteride or any tablet ingredient
Key precautions:
Whole tablets are coated to prevent contact during normal handling, but women who are or may become pregnant must never handle broken or crushed tablets, since the drug can absorb through skin. If accidental contact occurs, wash with soap and water immediately
People with liver disease should tell their doctor or pharmacist before use, since the liver clears this drug
Finasteride can lower PSA levels (used to screen for prostate cancer) by roughly half — tell your doctor you're taking it before any PSA test
How Does Harifin Compare to Other Finasteride Brands?
Harifin and the other Finasteride brands in store are all the same generic Finasteride 1mg oral tablet, with identical mechanism and DHT-lowering effectiveness. The main differences are brand, manufacturer, and price:
Propecia — original branded formula, highest price
Harifin — generic from T.O. Pharma, another Thai brand, budget-priced
Simple guide: Same ingredient across every brand — only brand, manufacturer, and price differ. Original brand → Propecia | Standard generic → Finasteride | Thai-made value → Firide | Budget T.O. Pharma option → Harifin | Another Millimed brand → Finascia
How Is Harifin (Oral) Different from Minoxidil (Topical)?
Harifin and Minoxidil are hair loss treatments with completely different mechanisms — either can be used alone, or together on a doctor's advice:
Harifin (oral) — blocks the DHT hormone at the root cause of genetic hair loss, best for widespread thinning, especially at the crown and frontal hairline
Minoxidil (topical) — dilates scalp blood vessels and pushes follicles into the growth phase faster; it doesn't affect hormones, so both men and women can use it
Most research shows combining both works better than either alone, since they act through different mechanisms. Minoxidil is not currently stocked in our store — if interested in combining treatments, consult a doctor or pharmacist for the right strength.
How Long Does Harifin Take to Show Results?
Harifin isn't fast-acting like a painkiller — it works gradually at the hormone level, so results take time:
First 1-2 weeks — blood DHT levels start dropping, but no visible hair change yet
3-6 months — hair loss noticeably slows, remaining hair strengthens, some men see fine new regrowth
6-12 months — full results based on individual response; continued use maintains them long-term
Some men notice temporarily increased shedding early on (the "shedding phase") before things improve — a normal part of the hair cycle resetting, not a sign the treatment isn't working. If it continues beyond 2-3 months, consult a doctor.

There's no single best time — morning or before bed works equally well. What matters is taking it at the same time every day to keep blood levels steady. Pick whichever time is easiest to remember, ideally tied to an existing daily habit.
Within 6 hours of your usual time, take it as soon as you remember. If more time has passed, skip that dose and continue with the next one as normal. Never double up to make up for a missed dose.
Harifin needs ongoing long-term use to maintain results — it's not a short course you finish and stop. If you stop, DHT rises again and hair loss gradually returns within months. Talk to a doctor before stopping.
Yes, this is a known "shedding phase" some men experience in the first 1-2 months, as the old hair cycle resets to a stronger new one. It usually settles within 2-3 months. If increased shedding continues longer than that, consult a doctor.
Blood donation services in many countries require at least a 1-month wait after stopping Finasteride, to protect a male fetus if the blood goes to a pregnant recipient. Always tell donation staff you are taking this medicine.
Generally yes — only a tiny amount of Finasteride is present in semen, so it's unlikely to harm a pregnant partner. Sperm quality issues are uncommon and usually normalise after stopping. If concerned, check with a doctor first.
Harifin must never be used in children — there's no approved use or safety data for that age group. Older men can generally use it as normal, but should tell their doctor about any liver conditions or other medications before starting.
Yes. A hair transplant relocates follicles from the back of the scalp to thinning areas, but it doesn't stop the genetic hair loss process affecting the remaining original hair. Continuing Harifin helps slow loss of the existing hair and protects the area around the transplant. Check with your transplant surgeon on the right duration.
Yes. Harifin uses the same standard Finasteride 1mg generic as other brands, made by T.O. Pharma under standard pharmaceutical quality control. The lower price reflects brand and packaging costs, not a weaker active ingredient.
No. Harifin is for men only — women must never use it under any circumstances. Women who are or may become pregnant must not even handle broken or crushed tablets, as the drug can absorb through skin and harm a male fetus.
