platinum

If you just have a little yellow in your hair that you wanna get rid of you should try purple shampoo, Shimmering lights is a purple shampoo from Clairol, it's good and cheap.

It'll make the hair look less yellow and more platinum blonde. But still if it's too dark now it won't make it look platinum/white blonde.

You might also need to bleach your roots, and tone the hair. You need a toner after bleaching to get platinum hair.

One of the reasons I started using the XL-0 was I wasn't getting enough 'lift' on my roots.

What I'd do is a strand test appying it on your roots only for the whole time minus 5 minutes. Then, apply to the already lightened hair for the remaining 5 minutes.

I just did my first strand tests less than a week ago....

Just mix a 1/2 tsp of color and 1/2 tsp of developer in a glass bowl for the strand test. Don't mix all of the color and developer together until you are ready to apply it to your head.

I used Clairol Herbal Essences XL-0 it made my hair platinum/white blonde. Actually, I'm trying to darken it know and it took so much pigment out I'm having trouble keeping med blonde color from fading.

I know most dont suggest OTC bleaching, but my hair always felt healthy after using it. I did my roots once a month for over a year and applied to the rest of my hair for only 5 minutes to 'refresh' it.

You can always get it and try a strand test. What color blonde is it now?
