Saw palmetto is one of the most recognizable botanical ingredients in hair-loss products. It is often discussed because of its relationship to androgen pathways, but the strength of evidence is not comparable to established drug therapies.
Why saw palmetto is discussed
Extracts of saw palmetto have been studied for effects on 5-alpha-reductase and androgen-related biology. That has led to interest in androgenetic alopecia.
What the hair evidence means
Small studies and reviews have reported possible benefits, but the evidence base is limited by study size, product variability and differences in oral versus topical formulations. Larger, well-controlled trials are needed before strong conclusions can be made.
Ingredient evidence is not finished-product evidence
A study on a specific extract, dose or formulation does not prove that every shampoo containing saw palmetto will prevent hair loss or block DHT. This distinction is important for accurate Regenepure marketing.
How to position saw palmetto in Regenepure DR
Describe saw palmetto as a featured botanical ingredient in a premium scalp-care formula. Avoid turning the ingredient into an implied drug claim for the shampoo. Consumers looking for proven hair-regrowth treatment can be directed separately to appropriately labeled minoxidil.

No.
Does saw palmetto shampoo block DHT?
Evidence on an ingredient should not be treated as proof that a finished cosmetic shampoo clinically blocks DHT.
Can I use saw palmetto products with minoxidil?
Cosmetic hair products can often be part of the same routine, but follow the minoxidil label and ask a healthcare professional about supplements or medications.
