Nail Jam is the passion project of Petra Janosikova, a nail tech with 16 years’ experience who is ‘deeply influenced by Eastern European beauty trends’.

Petra was influenced to enter the nail industry by a family member who was a nail technician. She began perfecting her gel polish skills, and upgraded her skillset to hard gel when the service became popular in her home country of Slovakia in 2008.
Slowly, Petra’s client base grew. While studying, she worked out of a room attached to her mother’s garage as an extra income stream.
“In 2016, I decided to completely change my life,” Petra says. “I left Slovakia with one small bag and moved to the UK.” This had a huge impact on Petra, and to begin with she juggled a full-time job while doing the nails of family and friends.
After having her daughter in 2021, Petra decided it was time to shift her focus back to her passion: nails. “My husband converted our garage into a nail salon and I managed to get fully booked within three months,” Petra says with a smile. “Though builder gel was taking off, I stuck to hard gel treatments and noticed how happy clients were with the longevity of the treatment.”
Blossoming the brand
“One day, I had a thought: what would happen if you could mix the formulas of builder gel and hard gel?” says Petra. This sparked something in her mind, and over the next few years the idea for a brand bloomed.

Petra had specific requirements for her product, and thus, supplier. Her top priorities included the supplier being based in Europe, ensuring high-quality ingredients and employee conditions, and providing full transparency, documentation and testing from reputable laboratories in the EU.
Bringing the brand to market
Enter Nail Jam. Petra describes it as a ‘professional UV gel brand created for nail techs who demand both safety and performance’.

The first products are set to launch at the end of October, and include ‘11 builder gels: six timeless core shades for every skin tone and five holographic glitters for quick, stunning results’.


Petra details what makes Nail Jam stand out:
• “Formulas that are free from TPO, HEMA, IBOA and IBOMA.”
• “Products designed in the UK and made in the EU, by specialists with over 20 years’ experience in UV gel manufacturing.”
• “A thixotropic self-levelling texture, which is ideal for overlays, sculpted extensions, dual forms and toenail reconstruction.”

“Nail Jam is a small brand with a big heart,” Petra says. “We care about every single customer who puts their trust in us, offering guidance, education and support alongside our products.”
Looking to the future, the brand owner adds: “We hope to expand our range with more innovative, unique products that are designed to be as functional as they are beautiful.”
