In the fast-paced world of Brussels, your nails need to keep up too. But should you choose the classic Semi-Permanent (Shellac) or the revolutionary strength of BIAB (Builder In A Bottle)?
Here is everything you need to know about Semi-Permanent and BIABÂ to make the right choice for your lifestyle.
Semi-Permanent vs. BIAB: Which one should you choose?
Choose Semi-Permanent (Shellac) if you have healthy nails, enjoy changing your color every 2-3 weeks and prefer short nails.
Choose BIAB if you have weak nails, are a “nail biter,” want to grow-out your nails longer or need a manicure that stays chip-free for up to 4 weeks.
The Key Differences
| Feature | Semi-Permanent (Shellac) | BIAB (Builder In A Bottle) |
| Purpose | Color, shine, and minor protection. | Strengthening and structural reinforcement. |
| Durability | Typically 2, maximum up to 3 weeks. | 3-4 weeks (high chip resistance). |
| Nail Health | Can be more damaging if done regularly. | Acts as a “protective helmet” for growth. |
| Application | Quick (applied like polish), treated in UV lamp. | Thicker gel, requires professional sculpting, treated in UV lamp. |
| Removal | Can be soaked-off with acetone or removed by electrical file.   | Can be removed by electrical file only. |
Why BIAB manicure is trending in Brussels for 2026
The “Apex” Advantage: Unlike thin Shellac, BIAB allows our technicians to build a natural “apex” on your nail, preventing snapping and peeling as it grows.
The Refill Factor: Unlike semi-permanent which must be fully removed, BIAB can be “infilled” (similar to gel), meaning less exposure to acetone and healthier natural nails over time.
If your routine is intense and you want a manicure you don’t have to think about for weeks – BIAB is the go-to for a long-lasting, ultra-resistant result that grows out beautifully.
If you prefer a glossy, natural-looking finish and enjoy changing your shades regularly – semi-permanent remains a timeless choice that offers both flexibility and elegance.
