Palms do not go dormant; they slow down but remain active year‑round. After a freeze, the only thing you can do is reduce watering to prevent root rot in the now‑inactive root system.
The green tissue you see inside the trunk is a good sign, but the brown emerging leaf suggests damage. There is no treatment to "nurse" a frozen palm back—time will tell if the growing point survived.
Keep the soil barely moist, provide no fertilizer, and wait for spring. If new growth emerges, the palm may recover; if not, it will need replacement.
