I have a bottle of Sally Hansen Protex Vitamin Fortified Strengthener. I've had it for years, is it still good or do these things expire?
Your Sally Hansen Protex Vitamin Fortified Strengthener has already expired. You should consider getting a new one. The product is dermatologist tested and has a very thin consistency.
The vitamins pretty much lose their effectiveness. I'd toss it if I were you.
Old vitamin fortified item would be worthless. No help!
