Starting finasteride correctly means a few specific things done before and at day one. This checklist covers all of them.
Starting finasteride well is a matter of doing a specific set of things before and around day one. This checklist covers them in order.
Before the intake
Pre-intake checklist
- ☐ Confirm the diagnosis. Pattern consistent with AGA: vertex thinning, temporal recession, or diffuse reduction. Family history on either side. If there are atypical features (sudden onset, patchy, associated symptoms), see a dermatologist before starting.
- ☐ Take baseline photographs. Overhead, front, both sides, crown close-up. Natural daylight. Hair washed the day before, air-dried, no products. Label with the date. These are your month-zero reference.
- ☐ Gather your medical history. Current medications (including supplements), any relevant conditions (liver, prostate, urological, mood), allergy history. Complete and accurate — this is what the provider reviews.
- ☐ If over 40: consider a PSA baseline. Finasteride suppresses PSA by approximately 50%. A pre-treatment value is useful for prostate cancer screening interpretation on finasteride.
- ☐ Decide on formulation preference. Oral tablet (most evidence, easiest logistics), topical finasteride (lower systemic exposure, different side effect profile), or combination topical. This affects platform choice.
At the intake
- Complete the form in one sitting — incomplete intakes cause delay
- Upload photographs that actually show the scalp clearly (this is the most common delay point)
- Disclose all medications honestly — the clinician needs this to prescribe appropriately
- Select 90-day supply if available (lower cost, fewer gaps); otherwise 30-day initially
- Enable auto-refill from the start
Day one
- Take first dose at a consistent anchor time (with breakfast, before bed — choose the time you will be most consistent)
- Note the date: this is month zero of a twelve-month assessment timeline
- Set a monthly reminder to take progress photographs under the same conditions as baseline
- Know the expected timeline: dread shed possible months one to three; no visible change expected in month one; first fair assessment at month twelve
Month one monitoring
- Track approximate daily shedding rate — pillow, shower, brush — for comparison in months two through four
- Monitor for side effects: sexual function, mood, any breast sensitivity. If any develop and are bothersome, contact the prescribing clinician rather than guessing
- Do not look for visible hair results in month one — there are none yet
- Do not double-dose if you miss a day
That is the full start. The biology handles the rest from here, on its own timeline. Your job now is daily dosing and monthly documentation for twelve months.
Common questions
What do I need before starting finasteride?
At minimum: a clear diagnosis of AGA (or strong clinical probability based on pattern, age, and family history), an appropriate telehealth platform or prescribing clinician, baseline scalp photographs, and an accurate medical history for the intake form.
How long does it take to get started on finasteride?
From deciding to start to having the medication in hand: typically three to seven days via an asynchronous telehealth platform for commercial tablets. Compounded topicals take slightly longer due to compounding time.
What should I monitor in the first month?
Baseline shedding rate (for later comparison), any side effects (particularly sexual function, mood), and dosing consistency. No visible hair changes are expected in month one.
