Are you looking for a brand that stocks Nail, Hair & Beauty products all under one roof? A brand where you can shop, earn points and spend your savings? Well look no further! Here at NSI (Nail Systems International) we are committed to bring our customers cost-effective quality products that don’t break the bank and it doesn’t stop there! We also offer our customers the Reward Point scheme, this is available to Professional and Student accounts when you shop through the NSI Nails App, online on the NSI website, over the phone and in store!

NSI is produced and manufactured in Philadelphia, USA. Since the 1950s, NSI has been a family owned business, Fred Slack and his son Rick Slack operated & manufactured high quality monomers, polymers, and other enhancement products for the professional nail industry.

While there seems to be a little uncertainty within the nail industry at the moment regarding ingredients in products and too much HEMA in others causing nail separation and allergic reactions, we just want to put our customers minds at ease.

The NSI UK phone lines and cash and carry will close at 1pm on Friday 23rd December 2022 until 8.30am on Tuesday 3rd January 2023

Since 1957, NSI has been a family owned and operated manufacturer of high quality monomers, polymers, and other enhancement products for the professional nail industry. Not only did NSI patent the first nail form, as early developers, inventors, and chemists, NSI pioneered and developed the first non-yellowing, cross linked formulations used in all traditional acrylic systems today. As pioneers, NSI was the first to introduce fibreglass-reinforced polymers, light activated liquid and powder acrylics, UV cured gels, and air and heat activated polish sealants. Our chemists work continually work along side nail technicians Denise Wright and Darlene Tewitz to deliver products which make the professional nail technicians work easier and to meet the demands for innovative products.

In terms of quality control, NSI goes the extra mile by providing batch and tracking numbers on all products. If a nail technician does experience a problem, it can be quickly identified and solved. 
NSI has proudly been manufacturing quality professional only nail products at it's own facility in America for over 25 years. All NSI Products are made in small batches with care and are quality tested to the highest standards to ensure all of our products stay consistent from batch to batch. We never test our products on animals and we never will. NSI is committed to providing the highest quality products to our most valuable resource…. The Nail Technician.
