Salt Palmetto for hair loss prevention?

Saw palmetto, also referred to as sol or salt palmetto in the discussion by Andrew Huberman, is known to inhibit the enzyme five alpha reductase, though it does so weakly. This enzyme is crucial in the conversion of testosterone to dihydrotestosterone (DHT), which can lead to hair loss by shortening the growth phase of hair and miniaturizing the hair follicle. By inhibiting this enzyme, saw palmetto can potentially extend the hair growth phase and mitigate hair loss effects. The typical recommended dosage is about 300 milligrams per day, divided into two or three doses for the best effectiveness. Despite its potential benefits, saw palmetto is not considered a robust treatment for reversing hair loss but may help in retaining and possibly growing new hair with minimal side effects 1 2.
