If you're the type of girl that likes to slick her hair back, whether you're having a bad hair day or just for fun, then a slick hairstyle is right on trend. This is one style that everyone can pull of regardless of hair length, texture or color. It's fast and easy to do, and all that's needed on your part is regular trims and some TLC. These hairstyles look best on healthy, glossy hair so get out those conditioning packs and hot oil treatments if you decide to go down this route. Once your hair is in tip-top condition, it's time to check out our style gallery to see what haircut tickles your fancy. Here are some ideas to get you started:

Diane Kruger (above) has added the slicked hair effect to a longer hairstyle. She illustrates an essential component of the slicked look: the combed side part. Importantly too, she's used hair product to keep her hair flat and slightly wet looking. Tucking her hair behind her ears helps maintain this flatness too.

You'll notice some similarities between this fashion and some other hair trends; for example the crop, smooth, sleek hair and the undercut.

Slicked hair, since it's slicked tight against the head, is similar to the crop in so far as its side part is a classic element of short hair (also invoking comparisons to the men's hair trend: the slicked back side part); and like the crop, women's slicked hair looks short. You can see from the Diane Kruger example too that her hair appears short (like a crop) even though it's long.

Slicked hair is like the smooth, sleek hair trend in so far as volume is almost totally absent from both hairstyles. But the difference is that slicked hair is not necessarily smooth and sleek. You want to use hair gel to make it wet and shiny, but also to get the textured effect created by the teeth of your comb. You can play with this texture by using a wide-tooth comb or even your fingers.

Women's slicked hair borrows a little from the undercut hair trend, led mainly by Rihanna. Slicking the sides of your hair can create a similar look to that achieved by using clippers to get an undercut, but with the added bonus that slicking your hair is reversible (unlike shaving your hair at the sides).
