Hair is particularly the most emphasized part of your body as it is the most exposed part which is also more visible and evident and is also unprotected from a variety of damaging factors like dirt, dust and heat. These exposures give way to premature graying of hair, limpness, breakage and dullness. It is for this reason that many people opt for hair coloring which adds shine and glamour. Covering all the gray areas your hair will look a lot younger and healthier after they are colored under the supervision of a top_hair colorist and are kept under proper care post the procedure.
Seems those that bring you hair color in a box have gotten the message. You'll notice more fruity scents rather than something that smells like a toxic waste dump when using them. Apparently all part of an effort to make the time spent coloring your hair seem more like putting on make_up rather than doing something that requires you don a hazmat suit.
