We're talking vibrant, very mom-unfriendly shades of lichen green, ice blue, and cotton-candy pink. Here, Joseph Mullen, colorist for lon Studio salon in SoHo, New York, shares his expertise. Because we never thought we'd say this, but it might be time to give your head the Technicolor treatment.

BLEACH
"First, you've got to strip your natural hair color (yes, even if you're blond). But bleaching isn't as risky as you'd think--you can hardly get it wrong. Also, if you're prone to dandruff, it can actually help dry out your scalp and remove the residue caused by excess oil in your hair."

COLOR
"Consult with your colorist to see if the shade you want suits your skin tone and if you'll be able to pull it off. Rather than going for a color-block dye, ask your hairdresser for a more multidimensional look. They could give the roots a darker shade of the same color to create a shadow and work with different intensities of color throughout your hair by painting highlights and lowlights. This balayage technique will make your hair look 'natural' even if you're changing it to blue."

MAINTAIN
"The secret to keeping your color looking fresh is to keep it hydrated. Choose a moisturizing shampoo specific to colored hair and a moisturizing conditioner rich in proteins like Christophe Robin Wheat Germ Mask (8 oz., $39; Christophe-Robin.com). Styling products don't have much effect on the color itself, so just keep using your favorite."
