The best way to freshen up your look is to start with a new hair color. It’s time to be playful, fun, and edgy when it comes to color. So, why not try a pastel dye? The best part is you can do it yourself in the comfort of your own home on a small budget.

There are so many options to choose from, including baby pink, lilac, lavender, light blue, and even pale green. If you’re feeling bold, you can even go for a trendy mermaid or unicorn look. Most of the pastel colors suit all skin tones, but you can check our recommendations in the buyer’s guide section.

Most popular hair dye brands now offer semi-permanent or permanent pastel hair dyes to fulfill the growing demand for DIY pastel colors.

In this post, I am sharing the top pastel hair dyes on Amazon to help you make the right decision before you pick your next hair color.

What is pastel hair & How do I prep?

Pastel hair refers to those light, bright colors, like cotton candy pink, pale blue and lavender. Pastel colors are vibrant and fun and perfect for those of you looking for something outside the traditional hair color palette.

Before you start dyeing your hair, you should know that pastel colors look best on virgin hair (hair that hasn’t been colored before). But, don’t feel discouraged because you can get excellent results if you bleach and lighten your hair first.

If you have light blonde hair color, it’s an easy process because it will probably work the first time. If you have dark hair, it might take a few weeks to achieve a light base. In either case, use high-quality bleach. Your hair should be a very pale shade of yellow for the pastel color to look its best.

Pastel hair dyes work on all hair types and textures, but it is a bit more challenging to get even looking results if you have curly hair. Bleaching curly hair causes a lot of damage, so you can alternatively do pastel highlights or an ombre look.

Buyer’s Guide: What to Look for in Pastel Hair Dyes

When it comes to choosing the best pastel hair dye, the process is similar to choosing any other boxed dye. You need to weigh the pros and cons of each formula and look out for harmful ingredients.

I will share some tips to help you pick the best option.

  1. Look at the ingredients: Since you have to dye pastel hair frequently, you need to use a formula that causes minimal or no damage to your hair. Harsh chemicals not only destroy your hair, but they are bad for your health too. So, begin by looking at formulas with the fewest number of harsh ingredients. Here are some of the ingredients to avoid:
  • Ammonia
  • PPD
  • Peroxide
  • Alcohol
  1. Semi-Permanent vs Permanent Dye: a semi-permanent dye is the best choice because this type of dye deposits color to your hair but the pigments don’t penetrate the hair cortex. As a result, semi-permanent dyes are less damaging and don’t leave your hair feeling as dry and brittle. Permanent dyes do lift color so they cause more damage, and since you need to re-apply pastel hues often, they are not the ideal choice.
  1. Vegan & Cruelty-Free: Using vegan products is an ethical choice but it’s also a good way to help the environment. As a general rule, vegan hair dyes are gentler and don’t contain the typical hair dye chemicals. Therefore, they can be used more frequently without risking your health.
  1. Consider your Skin Tone: Wondering which pastel hair color will suit you best? Begin by looking for a color that complements your skin tone. Here are some general pointers to help you out, based on skin tone.

Light/Fair Skin: If you have light skin, you should choose a pastel shade that doesn’t make you look washed out. The best match is a lavender or lilac purple warm tone, or even an azure green. Avoid the warmest colors which have red and orange undertones because these can really wash you out and make you look overly pale.

Medium Skin: Most pastel colors suit olive and medium skin tones. You can try pastel blues and greens. As well, you can try mermaid and unicorn hair too as all the colors suit your complexion. Even orange pastels look beautiful, so you have many options.

Dark Skin: All the pastel colors look great on dark skin tones. Bright purples, lavender, and fuchsia really stand out and make you look vibrant. Mint green and pale blues also complement dark skin. Ultimately, it’s up to you to choose the best pastel color but you can pull them all off, even a combination of multiple colors.

The Bottom Line

When it comes to pastel hair colors, you can stick to striking pinks, purples, green, and blues, or you can combine different shades to create mermaid and unicorn hair. Whatever you decide, you can rest assured that the pastel trend isn’t going anywhere anytime soon.

Make sure to pick the formulas that are safest for frequent use, and avoid those products that are full of harsh chemicals. After all, healthy hair is the best looking hair, regardless of color.
