Dip dyeing is a pretty funky and versatile technique in itself. It is the two tone dyeing technique for the hair in which the color of the hair strands closer to its roots (the scalp area) have a different color than the extreme ends of the hair strands, when ran down along its length.
The hairs at the root level are usually darker in shade and hue than the hair at the extreme areas, which is usually three to six times lighter. The color at the extreme ends of the hair strands, (may or may not) hardly matches the color at the roots of the hair strands.
Even though the technique of dip dyeing the hair strands seems to be pretty fixated, there is no restrictions or boundaries to your creativity. Having long hair to apply the technique of dip dye your hairs is a pure myth.
If you have short hair, and want your hair to look a little more elongated, try dip dyeing it with darker shades, for instance, if you have black hair, try going for the hues of maroon, dark brown etc. it adds on to the length by adapting themselves and amalgamating with your actual hair color.
Whereas if you want your short hair to stand out, and highlight themselves and the features of your face (such as your eyes, nose etc), you should try dip dyeing them light, and all together contrasting colors, such as green, blue, pink etc.
Have you always that short hair can only provide you comfort in the time of sunny season? It turns out your thought was just a bubble of illusion which enveloped your short hair.
It is time now for your hair to feel the colors for the world. Get going; create your own impression of dip dyeing.
