In this episode of the Gladden Longevity Podcast, host Dr. Jeffrey Gladden interviews Dr. Tamim Hamid, a PhD biomedical engineer with a background at NASA. Hamid explains how his experience developing space‑shuttle laser systems led to the creation of the Theradome laser helmet, a wearable device containing about 80 low‑power lasers that emit light at an 8° divergence to penetrate the scalp to a depth of ~5 mm. He describes the device’s power architecture (5 V, ~100 W equivalent, 20‑minute sessions twice a week) and two price points ($995 premium, $500 budget). Hamid proposes a novel hair‑loss mechanism: excess heat on the crown creates a “chimney” effect, fostering growth of the fungus Malassezia (malassezia fervor), which triggers inflammation; dihydrotestosterone (DHT) then targets inflamed follicles, causing androgenic alopecia. He recommends a daily antifungal regimen, specifically a forthcoming Theradome scalp‑conditioning shampoo containing pyroctinolamine and ketoconazole, to control the fungal load. The laser treatment, applied to a clean scalp, is said to halt DHT‑mediated loss and stimulate regrowth. Hamid cites double‑blind, sham‑controlled IRB studies showing an 89 % increase in hair count, far surpassing minoxidil (≈8 %) and finasteride (≈12 %). He discusses protocol details, device durability (≈18,000 treatments), and the limited role of biotin, vitamins, and hair transplants. The conversation also touches on Hamid’s other ventures, including a 440‑page book “Grow Back” that compiles scientific references, and future product releases (shampoo Q1 2026). Dr. Gladden shares his own background in interventional cardiology and longevity medicine, framing the discussion within broader themes of health optimization.
