Some client's nail plates seem to repel product no matter what the technician does. So, what do you do about serious lifters? Before Retention+, there wasn't a good answer to this question. But, with its unique and innovative 'covalent bonding' technology, Retention+ can bond directly to nail plates. This creates a stronger bond than even Radical and Acid-Free Primer can give. Retention+ has been designed for ultimate retention, virtually eliminating curling and lifting - ideal for all clients, especially problem lifters.
