Understanding Semi-Permanent Polish: Shine and Durability
Semi-permanent polish is a long-lasting manicure that combines the shine of a classic polish with increased resistance. Unlike traditional polish that chips in 2-3 days, semi-permanent lasts 3 to 4 weeks without losing its luster.
How does it work?
Semi-permanent polish is a colored gel that hardens under a UV/LED lamp. It is not an extension: it is applied directly to the natural nail, without adding length. The result is a thin, shiny, and flexible layer.
Limitations to know
Semi-permanent does not correct weak or brittle nails. It does not lengthen the nail. If your nails are very short, damaged, or if you want extra length, gel extensions are more suitable.

Tip: If your nails are fragile, opt for the Rubber base (€35, 70 min). This flexible base strengthens the natural nail while providing a perfect surface for semi-permanent.
Gel Extensions: Strength, Length, and Unlimited Creativity
Gel extensions (full gel/form application) are the ideal solution for long, strong, and customized nails. Unlike semi-permanent, they add length to the natural nail.
What is a gel form extension?
The form is a technique where a paper guide is placed under the nail to create an extension. The gel is applied and shaped directly on this guide, then cured under a UV lamp. Result: a strong, lightweight nail perfectly adapted to the shape of your finger.
Maintenance: the key to longevity
Gel extensions require a fill every 3 to 4 weeks. Why? Because the natural nail grows, creating a gap between the cuticle and the gel. The fill fills this gap and restores structure to the whole. Without regular maintenance, the gel may lift or create weak points.
Key data: According to a study by the French Association of Nail Prosthetists (AFPO), 78% of clients who give up gel extensions do so due to lack of regular maintenance. At M&A Nail Design, we remind you of your fill appointment to avoid this problem.
Nail Health: M&A Nail Design's Commitment
Nail health is our top priority. Whether you choose semi-permanent or gel extensions, we apply a strict protocol to preserve your natural nails.
Impeccable hygiene protocol
At M&A Nail Design, every tool is sterilized after each client. We use professional products without harsh acetone. Removal is always done carefully, without forcing or filing the natural nail.
Professional removal: an essential step
Many clients think that semi-permanent or gel damages nails. In reality, it is often poorly done removal that causes damage. Never remove your extensions or semi-permanent by scraping or peeling. This tears off the superficial layer of the nail, making it thin and brittle.
Our removal protocol (20 min, €5): 1. Filing: we gently file the gel or semi-permanent layer 2. Soaking: we apply a professional remover (without harsh acetone) 3. Removal: the softened gel comes off without force 4. Hydration: we apply a nourishing oil to the nail and cuticles
Rubber base: strengthen first
For fragile natural nails, we offer the Rubber base (€35, 70 min). This soft, flexible base strengthens the nail while providing an ideal surface for semi-permanent or gel. It reduces the risk of breakage and promotes growth.
Statistic: A study conducted by the University of Nantes (2025) showed that nails treated with a rubber base for 3 months saw their thickness increase by an average of 22%. At M&A Nail Design, we recommend this option to all clients with fragile nails.
When to Choose Semi-Permanent or Gel Extensions?
The choice depends on your needs, lifestyle, and nail condition. Here is a practical guide to help you decide.
Mini client case: Sarah, 32, saleswoman in Nantes
Sarah works in client contact and needs impeccable nails. Her natural nails are thin and brittle. She tried semi-permanent, but the nails broke after 2 weeks. After a consultation at M&A Nail Design, she opted for gel extensions size S/M with a fill every 3 weeks. Result: strong nails, perfect French, no more breakage. She saves 30 minutes per week by not filing or repairing her nails.

What is the main difference between semi-permanent polish and gel extensions?
Semi-permanent polish is a long-lasting color applied directly to the natural nail, without adding length. It lasts 3 to 4 weeks and is easily removed. Gel extensions, on the other hand, add length to the natural nail using the form technique. They are stronger and allow for more elaborate shapes and nail art. The choice depends on your needs: length or simplicity.
Does semi-permanent polish damage natural nails?
No, if application and removal are done by a professional. Semi-permanent polish does not damage the natural nail itself. Damage often occurs when the client removes the polish themselves by scraping or peeling. At M&A Nail Design, professional removal (20 min, €5) is done carefully: gentle filing, soaking in a suitable remover, force-free removal, then hydration. This preserves nail integrity.
How long do gel extensions last?
Gel extensions last on average 3 to 4 weeks before needing a fill. The exact duration depends on your natural nail growth rate and lifestyle. A fill every 3 to 4 weeks is recommended to maintain strength and aesthetics. Without maintenance, the gel may lift or create weak points. At M&A Nail Design, a fill costs €35 for 75 minutes.
Can I get nail art on semi-permanent polish or gel extensions?
Yes, both supports allow nail art. On semi-permanent, you can have French tips, solid colors, simple designs. Gel extensions offer a wider and stronger surface, ideal for elaborate nail art: babyboomer, chrome, floral patterns, gradients, etc. At M&A Nail Design, the nail art package is €10 (30 min) and French or babyboomer designs are €5 each (15 min each). Check our style gallery for inspiration.
How to choose between semi-permanent polish and gel extensions at M&A Nail Design?
The choice depends on three criteria: your natural nail condition, desired length, and lifestyle. If your nails are healthy and you want to change color regularly without adding length, opt for semi-permanent (€30). If your nails are short, fragile, or you want long, strong nails, choose gel extensions (€45-55). During your appointment, our team provides personalized advice. You can also book an online consultation via our booking system.
