not at all it washes out in anywhere from 8 - 24 shampoos depending on the process you use (if you sit under a hair dryer or not, if you do it will stay in longer). won't hurt your hair at all

try brown first you can go darker later. if you go dark now, you will be dark until it washes out months later. it won't ruin it but it won't wash out in the next few months.

Uh huh. It will screw everything up hate to tell you ,...a semi permanent will last until your hair grows out, semi my ****!

Use a henna or dye containing the words "TEMPORARY color or WASH OUT color"...that way it WILL come out if you don't like it!

The best way to see how you will look with different color hair is to use henna.For 2-3 weeks the color will become the initial one.And is not damaging for the hair.Try.
