Roland Peralta is co-founder and Chief Innovation & Product Officer of Nutrafol, the top dermatologist-recommended hair growth supplement brand, and the founder of The Root Cause Project. After experiencing thinning hair while recovering from thyroid cancer and rheumatoid arthritis, he began researching botanical nutraceuticals — and saw his hair growth improve as his overall health did.

That healing journey led him to co-found Nutrafol, which pioneered a science-backed, whole-body approach to hair health now used by more than 4,500 physicians, clinics, and stylists nationwide. Driven by the same belief in root-cause, functional medicine, Peralta went on to found The Root Cause Project to share stories like his own with a wider audience.

Peralta shares the personal health scare that unexpectedly led to his own hair regrowth, and traces how that discovery shaped his founding belief at Nutrafol: that hair loss is a symptom of body-wide imbalance rather than an isolated, genetic problem.

"We understood that hair was a reflection of inner wellness. And if you understand that simple concept, the approach that aligned with that understanding was whole body."
