Home hair colors

Hey everyone! Lets talk home hair color!
Lets see, Im a natural blonde with medium texture straight hair. I have never had a perm nor do i intend to ever get one! I prefer to color my hair at home rather than at the salon. So far, the coloring products I have used are Clairol Balsam Color and L`oreal Excellence. I was browsing through the colors at the store today and I came across Clairol Nice n` Easy. I told a friend I might switch to Nice `n Easy and she told me that Nice `n easy will DESTROY your hair. I always thought that brand had good reveiws and good results. She warned me of metallic salts in the product. If someone could tell me how well Nice `n Easy works, possibly clear up this misunderstanding my friend has I`d appreciate it.
Oh yeah, also does Balsam Color contain metallic salts as well? Thanx so much-Krystalle

NICE N` EASY is inexpensive for a reason : it is low quality and harsh on the hair. trust me. stick to a salon or to the more pricey alternatives. always read the ingredients and take into consideration the condition of your hair.
