Finasteride Shedding – What to Expect

What is Finasteride Shedding?‍‍

Finasteride is a medication commonly used to treat male pattern baldness by reducing levels of dihydrotestosterone (DHT), a hormone that causes hair follicle shrinkage. However, during the early months of treatment, some users experience increased hair loss, known as finasteride shedding. This is actually normal and temporary — a sign that the medication is beginning to work.

Why Does Shedding Happen?

Finasteride affects the natural hair growth cycle. When DHT is reduced, hair follicles that were in a resting or shedding phase (telogen) may rapidly transition to the active growth phase (anagen). As a result, old hairs are shed to make way for new, healthier ones. This sudden change may cause a short-term increase in hair loss.

When Does Shedding Start — and Stop?

• Months 1–2: Most users won’t see shedding this early, but changes begin internally.
• Months 2–3: Shedding often peaks here. You may also notice early signs of new growth.
• Month 6: Shedding usually stops, and new, thicker hair becomes more visible.
• After 1 year: Continued shedding at this stage is not typical and should be evaluated by a doctor.

How Much Shedding is Normal?‍

You might notice double the usual daily hair loss — 100–200 hairs a day — especially if you’re also using minoxidil. This is usually temporary and part of the regrowth process.

What to Do if You’re Shedding

• Don’t stop treatment. Finasteride takes time to show results — typically 6 to 12 months.
• Be patient. Shedding is often a sign the medication is shifting your hair into a healthier growth cycle.
• Consult a professional if shedding persists beyond six months or worsens after a year.

Finasteride shedding is a common, temporary part of the hair restoration process. Stick with the treatment, and you’ll likely see healthier, fuller hair in the long run. If shedding continues past the usual timeline, it’s worth checking in with a healthcare provider to rule out other causes.
