Ok you have a lot of trouble with shaving your legs you shave them and stuble is still left every time what should you do?

Basically you have two options.

1) If you're using a cheap razor or a low quality disposable one that may be a cause for it. If you want your legs to feel smooth you need a good razor. I recommend the Shick Quatro.

2) If you already have a good razor and the problem persists, you will need to wax to get the stubles to go away. Some women have naturally thicker hair, that grows faster, so it never truly feels smooth; unless it's waxed.
