Hair Color Damage

I want my hair a few shades lighter. How wrong he will be damaged if I used a permanent hair coloring kit Clairol?

not bad, it does much damage if you dye your hair too much and the use of iron products.

If you just use it once, it will not be terribly dry your hair. In fact, for the first week, especially after using the special air conditioner provided with the kit, it will be really soft and shiny. but after about a month (how long does the color, approximately), it begins to dry and brittle and loses its luster. In general it when people dye again and it will feel soft and shiny again (this is with a semi-permanent, and not just Clairol.) But if you just want to try once, and provided well after it will not cause too much damage. I suggest not to heat it a little too much style ... combination will really mess up your hair.

Are you do on virgin hair? If yes, then the damage will not be as severe as previously colored / bleached hair ...
you can not use a permanent hair coloring kit for thinning hair .. because the color does not lift color, you need to use peroxide, then use the kit staining.

If you go lighter than it can hurt your hair but not a lot darker. darker can also help you organize your style and give more volume
