Is there any liquid Propecia (for local treatment) and if there is would it be locally as effective as systemically? For example, could a regular 5mg Propecia tablet get dissolved in a liquid and be used locally?
Topical DHT blockers like solutions of Finasteride (Propecia) or Saw Palmetto for hair loss treatment have been studied in the past. However, they have not yet been proven to be effective for hair loss treatment. A reason for this might be the size of the molecular solution which makes it impossible for the medication to be absorbed from the scalp skin. More studies are being done to find vehicles that can increase the absorption of Finasteride from the skin surface (ref). At this point we do not have a proven DHT solution that can effectively control male patterned baldness.
