Dr. Amy Spizuoco: ozempic, hair loss, biotin myths, and hair treatments that actually work

Most people treat hair, scalp, and skin as three separate problems, each with its own shelf of products. But all three are built from keratin and run on the same growth signals, so thinning hair can say as much about how you're aging as a new wrinkle.

We dive deeper into this in the Biohacking Beauty Podcast with Dr. Amy Spizuoco. We also chat about what's really behind Ozempic hair loss, which hair loss treatments hold up in the evidence, and the popular hair supplement she calls the biggest waste of money.
