Techniques
Sapphire FUE
Sapphire FUE is classic FUE in which the channel-opening stage uses blades made of single-crystal sapphire rather than steel. Sapphire’s hardness and smooth surface allow finer, sharper channel geometry, aiming to reduce tissue trauma, crusting and recovery time.
- Anaesthesia
- Local
- Blade Material
- Single-crystal sapphire
- Channel Width
- 1.0–1.5 mm
- Session
- 6–8 hours
Principles
Harvesting follows the standard FUE protocol. V-shaped sapphire blades open channels with less tissue displacement than steel slits, matching channel size closely to graft dimensions. Channel geometry helps grafts remain stable and hold the intended angle.
Clinical Advantages
- Less micro-trauma at channel edges, with reduced oedema and crusting.
- Channel dimensions selected precisely for graft calibre.
- Higher grafts per unit area (dense packing) possible.
- Sapphire’s surface properties are intended to lower infection risk.
- An alternative for patients with metal sensitivity.
Candidates
Applicable to all patient groups suited to classic FUE; preferred where high recipient density is targeted, for fine or fragile hair, and where rapid recovery is a priority.
Limitations
- The main determinants of outcome are planning, graft viability and team experience rather than blade material.
- With limited donor capacity, single-session density is limited regardless of technique.
Recovery
Similar to FUE; crusts typically clear by day 7. Shock loss at weeks 2–8, new growth from months 3–4, final assessment at month 12.
