I want to dye hair, that has been highlighted with a peroxide based product, darker.What are the eff

For about a year now, I've being applying a half head of highlights, using a highlight cap, and Garnier summer hair (a spray that is 23% peroxide, and lightens hair using heat from hairdryers and the sun)

I want to return my hair to it's original colour (about a 6, dirty blond/light brunette)

If I dye it myself, what are the chances that the colour wont "catch" or will fade very quickly.

I know I can go to a hairstylist, but I'm hoping to do this myself.

Please let me know if you have experiance in this field.

When you first go darker you will notice the effect of the highlights. It's nice actually-it gives your hair that multi tonal effect. I would recommend going darker gradually, though. You can't always predict the effects of the colour and it's easier to go darker if you don't go dark enough the first time.

I have did this. You can do what you want to and it will work great for about 6-8 weeks. Then you,ll have to decide if you want to do it again or if its ok. Get a permant long lasting dye like loreal.
