appoximate Numbers of Grafts needed According to norwood Classification Of Baldness
Norwood Grade 1 shows minimal or no hairline recession. Hair transplantation is usually unnecessary at this stage, but for those seeking a thicker hairline, about 500–1,000 grafts may be required.
Norwood Grade 2 involves slight hairline recession at the temples. Restoration in this stage typically requires 1,000–1,800 grafts to maintain a fuller look
Norwood Grade 3 is marked by deeper recession in the temples, creating an “M” shape. Around 2000–2200 grafts can effectively restore the hairline and frontal area
Norwood Grade 4 displays significant hairline recession and visible thinning at the crown. Hair restoration generally demands 3000–3500 grafts to cover both areas adequately.
Norwood Grade 5 is characterized by a larger bald area as the hairline and crown begin to connect. Patients usually need 3500–4000 grafts to restore density.
Norwood Grade 6 shows severe hair loss with the bald area merging entirely between the crown and the front. Approximately 4500–6000 grafts are necessary to achieve proper coverage
Norwood Grade 7 represents the most advanced baldness, where only a small band of hair remains on the sides and back. Over 7000 grafts may be required, though results depend on the availability of donor hair
The Norwood Scale is the standard system to classify male pattern baldness. Each stage represents the progression of hair loss and the number of grafts typically needed for restoration
