My Buying Guides on Unicorn Hair Dye
When I decided to transform my hair into a magical unicorn-inspired masterpiece, I quickly realized that choosing the right unicorn hair dye can be both exciting and overwhelming. Here’s what I learned on my colorful journey, so you can pick the perfect dye for your own unique look.
Understanding Unicorn Hair Dye
Unicorn hair dye isn’t just one color—it’s a pastel or vibrant blend of shades like pinks, purples, blues, and greens that create an ethereal, iridescent effect. Most dyes are semi-permanent or temporary, which means they wash out over time, allowing me to experiment with different shades without long-term commitment.
Types of Unicorn Hair Dye
I found there are mainly three types of unicorn hair dyes to consider:
- Semi-permanent dyes: These last several weeks and fade gradually. I love these because they’re less damaging and let me switch colors often.
- Temporary hair chalks or sprays: Great for one-day looks or events. They wash out with shampoo and are super easy to apply.
- Permanent dyes: These are less common for unicorn styles but offer long-lasting color. However, they usually require bleaching first and can be harsh on hair.
What to Look for When Buying Unicorn Hair Dye
When I was shopping, I kept these key factors in mind:
- Color payoff and vibrancy: Choose dyes known for bright, true-to-tube colors. Reading reviews helped me find brands that don’t fade to dull shades.
- Hair health: Since unicorn colors often need a light base, I looked for dyes with nourishing ingredients like argan oil or keratin to keep my hair soft and strong.
- Ease of application: Some dyes come with applicator bottles or brushes, which made the process cleaner and faster for me.
- Allergen information: I always checked for any harsh chemicals or allergens to avoid scalp irritation.
- Price and quantity: Buying a kit with multiple colors saved me money and gave me more creative freedom.
Prepping Your Hair for Unicorn Dye
Before applying any dye, I recommend bleaching your hair to a pale blonde to make the unicorn colors pop. Using a good-quality bleach and following up with deep conditioning treatments helped me maintain hair health throughout the process.
Application Tips I Swear By
- Section your hair carefully to apply different colors neatly.
- Use gloves and protect your clothes with an old towel or cape.
- Leave the dye on for the recommended time to get the best saturation.
- Rinse with cool water to help colors last longer.
Maintaining Your Unicorn Hair
To keep my colors vibrant, I avoid washing my hair daily and use sulfate-free shampoos. I also try to wash with cold water and limit heat styling. Touch-ups every few weeks keep the hues looking fresh and magical.
My Favorite Brands for Unicorn Hair Dye
After trying several, these stood out for their color range and quality:
- Arctic Fox
- Manic Panic
- Lime Crime Unicorn Hair
- Pravana Vivids
Final Thoughts
Choosing the right unicorn hair dye made all the difference in my hair transformation. By considering my hair type, desired color intensity, and maintenance level, I found a product that turned my dream pastel rainbow into reality. Remember, unicorn hair is all about fun and self-expression—don’t be afraid to experiment and let your colors shine!
