Propecia, How Long Before It Works?

It starts to work as soon as you begin to take it. It works by blocking the enzyme 5 alpha reductase which converts testosterone to DHT. For results, you will have to wait to see any results. Most will notice results after the first 8 months. You will need to continue taking it for continued benefit.

The Three P's for Hair Loss--Propecia, PRP and Progesterone

It can take up to 3 months to see improvement. I suggest seeing an expert to evaluate your hair loss and consider the best treatment options. Propecia works best in combination with other non-invasive options like PRP/progesterone or transplantation. See an expert. Best, Dr. Emer

How long before Propecia works

Propecia is in your blood stream as soon as you begin taking it.  However, it takes about 3-4 months before it begins to take effect and slow the progression of hair loss.  Be patient, it will take about 6-9 months to see the full effect of the drug.  Also remember, not seeing changes, or more hair is still good news because you are not losing hair - That is the biggest benefit of the drug!

How long before propecia starts to work?

Matthewr,

It takes about 3 months for propecia to slow the hair loss, and 6-12 months before you see re-growth in the fortunate who have such a response. That is seen in 26% of men who mostly re-grow in the crown area.

Propecia

finasteride works pretty quickly usually for most patients in the first 2-4 weeks of daily use. However, the full effect of the medication will take at least 6 months, even up to 12 months.

Propecia

This drug starts to work fairly quickly but you might not see the results for 6-12 months while the hair grows out and the miniaturized hairs reverse
