Acrylic: maximum structure for long lengths
Best for beauty salons offering dramatic shapes, long extensions, and clients who are tough on their hands.
- Why technicians choose acrylic: reliable apex control, strong architecture, excellent retention for length.
- Salon considerations: noticeable monomer odour—ensure ventilation and dust capture.
- Service flow (summary): thorough prep → dehydrator/primer (system-specific) → tip or form → build free edge & apex → refine → seal with salon-grade top coat.
- Removal: reduce bulk with e-file, soak in acetone, gently refine, rehydrate with cuticle oil.
Gel (Hard vs Soft): clarity and comfort
Best for clients who prefer a lighter feel, glossy finish, and lower odour.
- Hard Gel: sculpted extensions & overlays; file-off removal; outstanding clarity for encapsulation and crisp shapes.
- Soft Gel: overlays and short extensions (brand-dependent); typically soak-off for quicker maintenance.
- Heat spikes: minimise by using thin layers, flash cures, and the correct UV/LED lamp.
BIAB (Builder in a Bottle): structured overlays, faster upkeep
Best for growing out natural nails, repairing post-damage peeling, or offering quick, structured manicures.
- Why technicians love BIAB: bottle-brush speed with builder strength; ideal for 2–3 week maintenance.
- Key technique: still build a micro-apex—flat overlays chip.
- Extensions: short–medium only (confirm brand guidance).
- Removal: usually soak-off; many techs rebalance to a thin BIAB base to protect the nail plate.
Nail health & salon safety essentials
- Prep, not pressure: precise cuticle work; avoid plate thinning and over-filing.
- Chemistry awareness: consider HEMA-free options for sensitive clients; patch-test when needed.
- Salon hygiene: dust extraction, masks, and surface disinfection protect staff and clients.
- Aftercare retail: professional cuticle oils, strengtheners, and home care support longer wear.
Troubleshooting common issues (and fixes)
- Lifting at sidewalls: improve dehydration/primer placement, cap edges, place apex correctly.
- Chipping or cracking: add structure; check lifestyle stress points (typing, lifting). For BIAB, ensure a micro-apex.
- Heat spikes (gel/BIAB): apply thinner layers, flash-cure, confirm lamp wattage/brand compatibility.
- Yellowing (acrylic): use quality top coats and advise clients on chemical/tint exposure.
Build a dependable pro kit (for beauty salons & nail bars)
- Prep: nail cleansers, dehydrators, acid/acid-free primers, lint-free wipes.
- Systems: acrylic powders & liquids; hard/soft gel builders; BIAB builder gels.
- Curing: brand-matched UV/LED lamps with correct output and timers.
- Perfecting: e-file with quality carbide/ceramic bits, hand files, buffers, dust extraction.
- Finishing: salon-grade base/top coats, cuticle oils, aftercare retail for clients.

FAQs for beauty salons & nail technicians
Which lasts longest in salon wear?
For long lengths and extreme shapes, acrylic and hard gel offer maximum structure. For overlays and short extensions, BIAB performs exceptionally well—especially with a defined micro-apex and regular maintenance.
Can BIAB be infilled?
Yes. Many professionals file to a thin BIAB base and rebalance, protecting the nail plate and speeding services.
Is gel safer for sensitive clients?
When applied and removed correctly, gel systems are safe. Consider HEMA-free formulas and always follow brand TDS and lamp guidelines.
Does acrylic damage nails?
Damage is usually from improper prep or removal (over-filing, picking). With correct technique and aftercare, acrylic services can be worn long-term.
