How will I achieve a vibrant Baby Blue color on dark hair?
You will need to pre-lighten your hair to a very light blonde before applying this color; we recommend using Smart Beauty Bleach-it Hair Lightener.
If my hair is yellowish blonde, do I need to re-bleach it?

Yes, you will, for example, pastel blue on yellowish blonde would result in green hair.
Should I bleach my dirty blond hair if I want to dye it a pastel color?

Yes, you should. If you try to dye it pastel now, you will either end up with a darker color or a muddy color.
If your hair is NOT light blonde or pre-lightened to a light blonde then the coloring process may not give the desired result.
How many packs do I need?

If your hair is thick or long, two packs may be required
How long should I wait after bleaching to add pastel color?

You can do color right after, for best results apply to dry hair.
How do I do color streaking?

To create color tips or streaks, pre-lighten portions of hair and then apply Smart Beauty vibrant color to the pre-lightened areas only.
How long is the development time?

Approx. 10-30 minutes.
How long will the color last?

Depending on your hair type and condition, the color will last for 3-10 washes.
How do I refresh the color?

Simply reapply the color to clean dry hair, following the instruction in the pack.
Can the color come out easily?

For best results a bleach bath.
