Hello everyone I have been wanting to dye my hair or put highlight or
just certain spots died. But a few questions. I baught  Loreal Paris
Feria Colour Strandws C90 Quickshimmering highlights for natural medium
to dark blonde hair. I want peoples opinion if that color would go good
with dark brown hair. If not what color or product name would?? Also If
it does go good is the Loreal Paris Product I mentioned washable? can
it be shampooed or some other chemical to wash it out or is it
permanant? Well let me know. I would prefer if you emailed me at
mlfen22@frontiernet.net. Thanks!!! :)

This product is a permanent hair color - it will bleach your hair to give you the highlights.  The description for the color is indicating that it is for people with natural medium to dark blonde hair.  If you hair is dark brown, the contrast will be severe and is not what is recommended.

Loreal has a web site that will show you the various options for their products.  Loreal Paris, you might want to check there for their recommendations.  

I am not aware of any temporary/shampoo out color that will lighten your hair.
