How it works
In plain terms.
Finasteride blocks 5-alpha-reductase, the enzyme that converts testosterone into DHT. DHT is the hormone that gradually shrinks follicles in male-pattern hair loss. Less DHT at the scalp means follicles stop shrinking and many recover.
How to take it
- One 1 mg tablet a day, with or without food, at any consistent time.
- Keep taking it; the effect depends on continued use.
- Do not crush or split tablets; women who are or may become pregnant must not handle broken tablets.
What to expect
- Shedding slows within about 3 months.
- Visible regrowth typically between 3 and 6 months; full effect at 12 months.
- Stopping usually reverses gains within 6 to 12 months.
Not for
- Women and children.
- Anyone with a known allergy to finasteride or dutasteride.
- Men who prefer a topical route can ask about the compounded topical blend.
Important safety information

Finasteride (oral)
Finasteride is FDA approved for male-pattern hair loss. It lowers DHT, the hormone that shrinks hair follicles.
- Women who are or may become pregnant must not handle crushed or broken tablets. Finasteride can cause abnormal development of a male fetus. It is not for use by women or children.
- Sexual side effects (decreased libido, erectile dysfunction, ejaculation problems) occur in a small number of men and in rare cases have continued after stopping the medication.
- Depression and mood changes have been reported. Tell your prescriber about any history of mood disorders and stop and call if your mood changes.
- Report breast lumps, pain, nipple discharge, or other breast changes.
- Finasteride lowers PSA levels. Tell any doctor ordering a PSA test that you take it.

Questions about Finasteride 1 mg
Anything else, call (714) 215-4740.
Will it affect my sex drive?
A small percentage of men report lower libido or erectile changes. Most resolve on stopping; persistent cases have been reported. Tell your prescriber about any change.
Does it work on a receding hairline?
It works best at the crown and mid-scalp and is less predictable at the temples. Pairing it with minoxidil helps.
Does it affect PSA tests?
Yes, it roughly halves PSA. Tell any doctor ordering a PSA that you take finasteride.
