SMP for Crown Thinning — Marlow Men's Vertex Treatment
Crown thinning — a visible scalp disc at the vertex with retained peripheral hair — is one of the most treatable presentations for SMP in Marlow. Treatment fills the central diffuse zone with density-matched pigment deposits, blending seamlessly into surrounding hair.
Crown Thinning Treatment Zone by Norwood Grade
| Grade | Crown disc diameter | SMP approach | Cost range |
|---|---|---|---|
| III Vertex | 5–7 cm | Central fill, peripheral blend | £700–£950 |
| IV | 7–10 cm | Extended fill, transition gradient | £900–£1,200 |
| V | 10–13 cm | Crown + frontal connection | £1,100–£1,500 |
Blending SMP into Existing Hair: Transition Zone Technique
The peripheral blend — the 2–4 cm annular zone where pigment transitions into existing live follicles — is the most technically demanding aspect of crown SMP. Skilled Marlow practitioners use three blending techniques:
- Gradient under-density — 30–40% saturation at the outer blend ring, increasing to 80–90% toward the central zone
- Follicle-aligned spacing — matching the natural spacing of surrounding hair (~4–6 follicles/cm²) in the blend zone
- Multi-tonal layering — 2–3 pigment shades within the blend zone to replicate natural hair density variation
How Many Sessions for Crown-Only SMP?
Crown-only treatment (no hairline work) typically completes in 2–3 sessions. The reduced surface area means Sessions 1 and 2 are shorter — 1.5–2.5 hours each — with Session 3 as approximately 1 hour of refinement.
