Gel versus classic manicure at home: the hygiene system matters more than the polish
Sterilisation is where home visits diverge most from a fixed salon. A salon has an autoclave in the back room; a freelancer has whatever fits in the bag. The standard you can reasonably demand: metal implements arrive in sealed sterilisation pouches, ideally with the colour-change indicator visible; files and buffers are single-use or yours to keep; e-file bits are either fresh or pouch-sealed; and any soak bowl gets a disposable liner. Blue disinfectant jars are for in-session dips, not sterilisation, and a spray of alcohol over yesterday's tools does not count. Fungal and bacterial nail infections transmit exactly this way, and they are tedious to treat.
Classic polish is more forgiving at home in one specific way: mistakes are reversible with remover in minutes. Gel removal, by contrast, is where home nails most often go wrong, because rushing it with peeling or aggressive filing takes layers of nail plate with it. Proper removal means acetone soak or wraps for ten to fifteen minutes, gentle scraping, and no force. Book the removal into the appointment rather than treating it as a favour at the end, and expect the visit to run longer because of it.
