One-Para Summary
The semi-permanent eyebrow hair method uses an electric PMU machine with 0.1mm needles to create natural, 3D hair-like strokes in the epidermal layer. Lasting **12–18 months**, it restores sparse brows, repairs scars, and reconstructs eyebrows. Compared to microblading, it offers less trauma (0.5–1mm depth) and higher precision. Pre-procedure involves 3-point mapping, while post-care requires 7 days of irritation avoidance and a 4–6-week touch-up.

IV. Management Protocol
-
Pre-Procedure:
- 3-point mapping (brow start/arch/tail)
- Pigment selection: 1–2 shades lighter than hair color
-
Post-Care:
- Avoid: Swimming/sauna/skincare for 7 days
- Apply antimicrobial balm 3x/day for 3 days
- Touch-up increases retention by 40%
V. Critical Notes
- Hygiene: Use single-use needles
- Portfolio: Provide case studies of similar facial structures/skin tones
FAQ
Q1: What’s the core difference between hair stroke and microblading?
A1: Hair stroke uses an electric device for epidermal implantation (0.5–1mm depth), ideal for natural sparse brows. Microblading employs manual blades on the dermis (1–1.5mm depth), better for dramatic, dense results.
Q2: Can oily skin use hair stroke? How to optimize results?
A2: Yes, but combine with ombre shading:
- Base ombre layer for durability
- Hair stroke top layer for texture
- Retention extends to 12–15 months (+25% vs pure hair stroke)
Q3: What to do about pigment diffusion post-treatment?
A3: If slight discoloration occurs within 3 days after surgery, it is a normal metabolic phenomenon and can be improved by the following methods:
- Adjust needle angle to 85–90° during touch-up
- Use nano-pigments (≤50nm particle size, e.g., Sweety®)
- Ice compress within 48 hours to reduce swelling
