ARTAS robotic hair transplant candidates must have straight to slightly wavy dark hair, adequate donor density, and hair loss patterns between Norwood 3 and Norwood 6. The system's imaging technology has specific requirements that exclude certain hair types and loss patterns that manual FUE can still address.
This FAQ covers the specific qualifications, limitations, and disqualifying factors for the ARTAS system.
Hair Type Requirements
The ARTAS robotic system relies on optical imaging and AI pattern recognition to identify individual follicular units in the donor area. This technology has specific requirements:
Compatible hair types:
- Straight hair (ideal)
- Slightly wavy hair (acceptable)
- Dark brown to black hair (best contrast)
- Medium brown hair (acceptable with good scalp contrast)
Incompatible or challenging hair types:
- Tightly curly or coiled hair (the system cannot accurately predict the subsurface direction of curved follicles, risking transection)
- Very light blonde hair (insufficient contrast for imaging)
- Red hair (the wavelength used by the imaging system has difficulty differentiating red hair from scalp)
- Gray or white hair (low contrast against lighter scalp)
This is the most significant limitation of ARTAS compared to manual FUE. A skilled manual surgeon can extract follicles of any hair type by adjusting technique in real time. The ARTAS system works within fixed optical parameters.
Norwood Stage and Graft Limits
ARTAS performs robotic FUE, and the graft limits reflect general FUE constraints along with some system-specific factors:
| Norwood Stage | Grafts Needed | ARTAS Suitable? |
|---|---|---|
| Norwood 2 | 800-1,500 | Yes, but often unnecessary for this volume |
| Norwood 3 | 1,500-2,200 | Yes, well within range |
| Norwood 4 | 2,500-3,500 | Yes, standard ARTAS case |
| Norwood 5 | 3,000-4,500 | Yes, may need multiple sessions |
| Norwood 6 | 4,000-6,000 | Possible, but pushing system and donor limits |
| Norwood 7 | 5,500-7,500 | Often not recommended; insufficient donor for full coverage |
The ARTAS system can typically harvest up to 1,500-2,000 grafts in a single session. For larger cases, sessions may need to be split across two days, or ARTAS can be combined with manual extraction to increase the total yield.
For comparison, manual FUE can harvest up to 5,000 grafts per session, and FUT (strip) can yield up to 4,000. This makes ARTAS most efficient for moderate graft counts.
Donor Area Requirements
Beyond hair type, your donor area must meet minimum density thresholds:
- Minimum density: Approximately 60-80 follicular units per cm2 in the harvest zone
- Average density by ethnicity: Caucasian (170-230 FU/cm2), Asian (140-200 FU/cm2), African (120-180 FU/cm2)
- Safe extraction limit: No more than 45% of follicular units should be extracted from any area to avoid visible thinning in the donor zone
The ARTAS system maps the donor area during the procedure and creates a randomized extraction pattern to prevent over-harvesting from any single zone. This is one advantage of the robotic approach: it enforces consistent spacing between extraction sites.
Who Should Not Get ARTAS
The following conditions typically disqualify candidates:
- Active scalp conditions: Psoriasis, severe dermatitis, or active infections in the donor or recipient area
- Unrealistic expectations: Expecting full head-of-hair density from a single session at Norwood 5+
- Unstabilized hair loss: If your Norwood stage has changed in the past 12 months, surgery should wait
- Age under 25: Hair loss pattern is not yet predictable enough for surgical planning
- No medical therapy: Patients who refuse finasteride or minoxidil may see continued loss around transplanted areas
- Autoimmune hair loss: Alopecia areata, scarring alopecias, and other autoimmune conditions are not suitable for any hair transplant type
- Very thin donor area: If donor density is below the minimum threshold, neither ARTAS nor manual FUE will produce satisfactory results
Patients who research procedures report 60% fewer post-op surprises. If you are told you are not an ARTAS candidate, ask whether manual FUE or FUT might work instead, as the limitation may be specific to the robotic system rather than to transplantation in general.
ARTAS vs. Manual FUE Candidacy
| Factor | ARTAS | Manual FUE |
|---|---|---|
| Curly hair | Often excluded | Compatible |
| Light/red hair | May be excluded | Compatible |
| Max grafts/session | 1,500-2,000 | Up to 5,000 |
| Consistency of extraction | High (robotic precision) | Depends on surgeon skill |
| Cost premium | 10-30% more than manual FUE | Standard FUE pricing |
If you are a good ARTAS candidate, the system offers consistent extraction quality. If your hair type or graft needs fall outside its range, manual FUE with an experienced surgeon is the better option.
Find Out If You Qualify
The first step toward any hair transplant is knowing your Norwood stage, graft needs, and donor area characteristics. An accurate starting assessment prevents wasted consultations and helps you ask the right questions.
