- Finasteride (brand name Propecia) is an oral medication that blocks DHT production systemically. It is highly effective for androgenetic alopecia but carries potential side effects including sexual dysfunction, depression, and ongoing post-drug syndrome in rare cases.
- Peptide shampoos work topically and affect DHT locally rather than throughout the body. This targeted approach appeals to those concerned about systemic hormone manipulation. However, the DHT-blocking effect of topical peptides is less potent than oral finasteride.
- For many people, especially those with mild to moderate hair loss, peptide products provide sufficient DHT management without systemic exposure. Those with aggressive hair loss may still require finasteride or similar medications to achieve meaningful results.
- The choice often comes down to risk tolerance and severity of hair loss. Peptide shampoos make sense as a first-line treatment or maintenance therapy. Finasteride remains an option for those who need stronger intervention.
