Not applicable: Generally radiation dose not cause hair loss, only during brain radiation. This is usually an issue with chemotherapy after chemotherapy it usually takes 3 weeks to notice hair growth, but several months to "regain" your hair.

If permanent loss: Due to higher dose (> 50 gy), and after lower doses, for instance, prophylactic brain treatment in small cell (25 gy), i cousel my patients that peach fuzz in 3-4 months, and full return in 6 months.
