Our Formulation Ethos. Made in Wales. We believe in doing things properly. We launched HONA with expert support from world-class chemists, including our original collaboration with Jim McConnell, to ensure our gel system met the highest safety and performance standards. Today, as we grow, we’ve brought our product development inhouse and are so proud to say we are truly a Welsh brand with our products made in Wales. This gives us full control over our formulas, ingredient transparency, and quality. While allowing us to innovate faster, test more rigorously, and respond to the needs of our community. Our products are developed by a small team of trusted chemists, tested with industry professionals, and guided by Charlotte Henson’s extensive knowledge as a working nail tech and educator. This balance of scientific expertise and industry experience is what keeps HONA products safer, stronger and smarter, always.
Colour Representation: Every effort is made to ensure that all our product imagery is as accurate as possible. There is several real life images on each product page. However due to colour/resolution settings on electronic devices, the colour representation may differ slightly from the physical product.
