I don't go for nail treatments and I never have. That's not to say I never will, but I figure that it is an unnecessary spend when I prefer to spend my pennies on skincare and cosmetics.
Sally Hansen's Complete Salon Manicure range boast 5 nail treatments in 1; this one polish claims to provide: a base coat, strengthener, growth treatment, colour and top coat. At Boots, they currently retail for £6.99, so are worth checking out, especially as there is a wide range of shades to choose from.
I applied Seche Vite top coat on top for extra lasting power and I had five days of wear with minimal, unnoticeable chipping.
