The history of blue hair (it's not as new as you may think!)
Do You Need Bleach to Dye Your Hair Blue?
If your hair is naturally dark, you'll probably need to bleach it to have the dye show up clearly. This is especially important if you'd like to dye your hair a pastel shade or a particularly bright, clear color. If you're dying it dark steel blue or navy, though, you may be able to dye over your natural hair. Although it's possible to use bleach from a drugstore or beauty supply store, your safest bet is to have your hair bleached professionally. Make sure your hair is healthy and moisturized before bleaching it to minimize damage.
However, if your hair is naturally blonde, you'll be able to dye it almost any shade of blue without bleaching first. You may need to lighten it a few shades if you're a natural medium to dark blonde, and you'd like to dye your hair pastel.
How Long Does it Take For Blue Hair to Fade?
According to the typical person's experience, blue hair fades more slowly than other bright colors such as red or purple. However, even though the pigment stays in the hair for months, the vibrancy of the initial dye usually fades after a week or two. But don't worry - you can still end up with a great-looking 'do because the color often fades to a lighter, but still appealing, color.
To maintain the brilliance of your hair, wash it only when necessary (two to three times a week is sufficient for most people) and use color-safe shampoo and conditioner. Wash it in cold water, too, since hot water opens the cuticle and makes it easier for the color to escape.
So, are you ready to embrace a whole new look? Or do you need a little bit more encouragement? Either way, continue scrolling to find all the inspiration you'll need!
