For patients with advanced baldness (Norwood 5, 6, 7), a standard 2,000–3,000 graft FUE session is barely a down payment on full coverage. Two or even three surgeries spaced 9–12 months apart used to be the only option. Today, Giga (or Mega) Sessions — 5,000+ grafts in a single day — make full coverage possible in one surgery. But not every clinic should attempt them.
Terminology varies, but broadly: **Standard FUE:** up to 2,500 grafts. **Mega Session:** 2,500–4,500 grafts. **Giga Session:** 4,500–6,000+ grafts in a single day. The distinction matters because surgical, logistical and donor-management challenges scale non-linearly with graft count.
