All of our semi-permanent and temporary hair colors are formulated without bleach, lighteners, or harsh chemicals—so you can rock your unicorn style sans damage. Keep reading to learn more about the best hair dyes for experimenting with your color. 

What Is The Best At-Home Hair Dye?

The best at-home hair dye for you is the one that suits your needs best. Whether you’re going for an ultra-vibrant look or want to add a tint of color to your tresses, we’ve got the formula for your hair goals. 

If you’re not sure where to start, check out our swatch guide to see how our damage-free hair dye colors appear on different starting shades. Want something even more unique? Try combining complementary shades or play around with our hair color mix-ins to create a customized color that is 100% unique—just like you.

Do I Need To Bleach My Hair Before Using Hair Dye?

Our damage-free hair dyes and hair tints are formulated without bleach or chemical lighteners, so they won’t lighten your hair. As such, you’ll notice the best color payoff when you start with light hair. If your strands are between levels 1 and 6 (this includes black to light brown hair), we recommend bleaching first for vibrant results. Processed, pre-lightened hair will always hold pigment the best, while virgin strands won’t fully absorb it. To handle your complete hair journey at home, start by bleaching with one of our easy bleach kits.

For those with a darker-starting shade that don’t plan on bleaching, try some of the most pigmented shades of our Unicorn Hair Full Coverage. The best colors for you include Chocolate CherrySea WitchMysticValentineFlaming Red, and Anime. When used on dark hair, these nourishing, semi-permanent hair dyes deposit pigment for a subtle tint of color. 

To liven up your look sans commitment, use a temporary hair color, like our washable Unicorn Hair Color Sprays. These high-intensity color sprays deliver a blast of bold pigment that rinses out easily with water. Best of all, they work on all hair colors, from the lightest blonde to the deepest black.

What Is Semi-Permanent Hair Dye?

Our semi-permanent dyes deposit high-impact pigment without lightening or chemically altering your hair. Because they don’t contain a developer, the base color you start with is crucial to how the color will deposit on your hair. Note that Unicorn Dye should never be mixed with developers, lighteners, or permanent hair colors. 

Unlike permanent dyes, these semi-permanent hair colors fade gradually, usually over the course of a few weeks. The DIY-friendly dyes are ideal for those who like to change up their look often but don’t want to deal with the damage (or the hassle) of permanent hair dye. Each one is made with an ultra-conditioning base that won’t cause any damage to your hair. 

Our semi-permanent dyes are available in 31 eye-catching colors, including electric pinks, neon greens, muted mauves, and more. Shop by hair color to find your perfect match.

How Long Does Semi-Permanent Hair Dye Last?

The lifespan of your semi-permanent color depends on a bunch of factors, including whether your hair has been previously processed, how pigmented your shade is, how often you shampoo (and whether you use a sulfate-free formula), and your lifestyle. Hot tip: Avoid heat styling and chlorinated pools if you want to extend the longevity of your new hue.

To keep your semi-permanent hair color looking vibrant for as long as possible, we recommend showering with cool water and washing your hair less frequently (dry shampoo is your friend). When you do lather up, use color-safe products, like our Unicorn Hair Color Shampoo and Unicorn Hair Color Conditioner, to help preserve your pigment. 

What Is Full-Coverage Hair Dye?

Our full-coverage hair dyes are our most pigmented, super-saturated formulas. These customer-favorite dyes deliver truly vivid color on pre-lightened platinum to medium blonde hair and add a tint to dark blonde and light brown strands. This color gradually fades over the course of several weeks. Currently, we offer 25+ full-coverage shades. (Bonus: Each one has a delightfully-sweet scent!)

If you prefer a more muted shade, try our Unicorn Hair Tints. They’re less pigmented than our full-coverage formulas and deliver a subtle wash of color for a softer watercolor effect. These dyes are available in 10 shades and work best on pre-lightened platinum to pale blonde hair.
