Finasteride is not typically classified as a dietary supplement. It is a prescription medication that is primarily used to treat conditions such as benign prostatic hyperplasia (BPH) and male pattern baldness (androgenetic alopecia). Finasteride works by inhibiting the enzyme 5-alpha reductase, which is responsible for the conversion of testosterone to dihydrotestosterone (DHT), a hormone that contributes to prostate growth and hair loss.

For BPH, finasteride helps reduce the size of an enlarged prostate, which can improve symptoms like difficulty in urinating. For male pattern baldness, it can help increase hair growth and slow down hair loss.

As it is a regulated prescription drug, finasteride is not available as an over-the-counter supplement. If you have any other questions or need information about specific supplements, feel free to ask!

There are several natural ways to help inhibit DHT (dihydrotestosterone) in males, which can potentially aid in reducing hair loss:

1. Saw Palmetto: This herb contains phytosterols and fatty acids that act as nonselective inhibitors of 5α-reductase, the enzyme responsible for converting testosterone into DHT. Studies have shown that saw palmetto can decrease DHT binding to androgen receptors and may promote hair growth, especially on the vertex of the scalp¹.

2. Pumpkin Seed Oil: Pumpkin seed oil contains phytosterols that inhibit 5α-reductase. It has been shown in studies to significantly increase hair count in patients with androgenetic alopecia (male pattern baldness) when taken orally².

3. Green Tea Extract: The polyphenol epigallocatechin gallate (EGCG) found in green tea can inhibit 5α-reductase activity and has demonstrated potential benefits in promoting hair growth and reducing DHT levels.

4. Stinging Nettle Root: This plant extract contains compounds that can inhibit the conversion of testosterone to DHT, similar to saw palmetto.

5. Lifestyle and Nutritional Adjustments: Maintaining a diet rich in antioxidants can help neutralize the reactive oxygen species that may contribute to hair loss. Consuming a balanced diet with essential vitamins and minerals supports overall hair health and potentially reduces DHT-related hair loss³.

These natural approaches can be considered as part of a broader hair loss management strategy, particularly for individuals who prefer to avoid prescription medications like finasteride.
