hi all, i have the worse nails ever, they've always been soft but every so often i pick of my enhancements which doesn help. ive never had nails above the tip of my finger. i want to be able to recommend a product to customers with these types of nails. so far ive really only tried the 411 toughen up. is it suitable on its own as a nail strengthener? any other suggestions? an opi rep came round one day and her nails were fab, at 1st i thought they were enhancements but she swore by nail envy.
