Two weeks into minoxidil and finasteride, it’s natural to start checking the mirror for signs of change — especially at the crown, which is often the area people worry about most. The short answer: two weeks is far too early to expect visible regrowth, and that’s true for almost everyone, regardless of how their hair loss responds long-term.
What the typical timeline looks like
Hair growth is slow, and both minoxidil and finasteride work by influencing the hair growth cycle rather than causing instant change. According to patient education from the American Academy of Dermatology and manufacturer-independent clinical summaries, the general pattern looks like this:1,2
- First 2–8 weeks: No visible improvement is expected. Some people using minoxidil actually notice increased shedding during this window, sometimes called “dread shed,” which reflects hairs in the resting phase being pushed out to make room for new growth — not a sign the treatment is failing.2
- 3–4 months: This is typically the earliest point where finer, shorter regrowth may start to become noticeable, particularly in well-lit photos taken from a consistent angle.
- 6–12 months: Most clinical trials measuring meaningful, visible density improvements use this window. The AAD notes that both minoxidil and finasteride generally need to be used continuously for months before their full effect can be judged.1
Does the crown respond differently than the hairline?
Clinical trial data on finasteride and minoxidil has generally shown more consistent, reliable regrowth at the crown (vertex) than at the hairline or temples, which tend to be harder areas to treat for most people.1 That’s encouraging for crown-focused concerns specifically, but it doesn’t change the timeline — the crown responding “better” still means months, not weeks.
What actually predicts a good response
The research points to a few consistent factors: starting treatment earlier in the course of hair loss (rather than after years of advanced thinning), consistent daily use without gaps, and — for topical minoxidil specifically — correct application to a dry scalp rather than wet hair.2 None of these guarantee a specific result, since individual response varies and some people see much more improvement than others.
When it’s worth checking in with a prescriber
If you’re not seeing any change after a full 6 months of consistent use, or you notice side effects that concern you, that’s a reasonable time to check in with the prescriber who’s managing your treatment — whether that’s an in-person dermatologist or a telehealth provider. They can assess whether the diagnosis (androgenetic alopecia vs. another cause of shedding) is correct, whether the treatment plan needs adjusting, and whether combination therapy or a different approach makes sense for you. This article doesn’t recommend starting, stopping, or changing any medication or dose — that decision should stay between you and the clinician who prescribed it.
The bottom line
Two weeks in, the most useful thing you can do is take a consistent baseline photo, keep using your treatment as prescribed, and revisit the question around the 3–4 month mark — with the real assessment point closer to 6–12 months. Early shedding or “nothing happening yet” is the norm, not a red flag, for almost everyone starting these treatments.
