We all hate running out of our favourite mascara or using up our conditioner before our shampoo.

It always seems to happen before a big night out, when everywhere is closed and you don't have the time or money to replace anything.

At Shemazing HQ, we love a good beauty hack, and these five simple product swaps and tips should handle even the worst beauty blunders.

1. You're out of shaving foam, and your legs resemble those of a mature gorilla.

Try hair conditioner instead; it won't foam up but, the silicones in conditioner soften the hair for the razor to glide through. 

2. No eye-make-up remover, to combat last night's glitter eye shadow and a half a ton of mascara.

The solution? Almost any oil will remove eye makeup, so try dabbing on some coconut oil or olive oil. 

3. The worst of all, no dry shampoo.

Dry shampoo has saved us from so many bad hair days and greasy mane situations.

However, a great inexpensive substitute is talcum powder. Go easy with it, as a little goes a long way.

Talcum powder is also fab for preventing shaving rashes on the bikini line and underarms.

4. You need to get rid of your patchy fake tan, and you don't have an exfoliator.

Just add some sugar to your shower gel, and scrub away to your heart's content! Bye bye, dodgy orange tan!

5. Favourite nail varnished all dried up?

There's still a way to rescue it; just add a couple of drops of nail varnish remover, and shake.

Don't add too much or the mixture will become too watery.
