This post will share the top blue hair dyes on Amazon to help you make an informed decision.

How to prep for blue dye

The one crucial piece of info to note is that blue is one of those dye colors that fades relatively quickly compared to most other hues. The best way to make the dye last longer is to lighten your hair before coloring.

Here are some other helpful tips to help you get a vibrant head-turning color.

  1. Use a clarifying shampoo before dyeing: this type of shampoo removes any build-up on your hair and scalp. It also removes any leftover color from previous dyes. A clean canvas is always best when coloring your hair at home.
  2. If your hair has another dye on it, you need to use a color remover. This product removes and lifts off other colors. If you have light hair, then you can apply the blue color over it. However, if you have dark hair, you are better off bleaching it to ensure the blue dye looks good.
  3. If you want a blue tint, you can dye dark hair, but you need to lighten first if you are looking for a vibrant or neon type of blue hue.
  4. After decoloring or bleaching, use a deep hair conditioner to help repair the damage. If your hair is healthy, the blue color will look much better, and the dye won’t completely damage your locks.
  5. Wait a few days at least before applying the blue dye, or else you can really ruin your hair texture. There’s a chance you end up with brittle, broken, and dry hair, not to mention scalp irritation.

Buyer’s Guide

Selecting the best blue hair dye is a bit tricky because there’s such shade variety. Therefore, I think it’s best to consider some of the following factors when choosing your dye.

Fading

If you use temporary or semi-permanent hair color, likely, the formula deposits color pigments, but those pigments don’t penetrate the hair shaft. These formulas are not as long-lasting as permanent dyes. However, there is a major advantage to using them because they fade out gradually. You want a slow fade formula because it makes the blue lighter and pastel-like, so it’s still wearable.

Bleeding

Check out buyer reviews to see if the formula bleeds. Color bleeding occurs when you wash your hair. If there is an intense amount of bleeding, your color washes out quickly, so it’s not a good formula.

Gentle Formula

For blue to stay vivid, you need to re-apply the dye often. Therefore, you don’t want a damaging formula. Instead, opt for gentle, natural, and vegan formulas. These are gentle on the hair and most often have excellent conditioning properties.

Avoid harsh chemicals such as ammonia, PPD, peroxide, parabens, and alcohol. These make your hair dry and brittle.

Easy Application

Look for dyes that have a non-drip formula, preferably thick creams or gels. Since you are applying a bold, bright color, you don’t want it to drip down on your skin or clothing as it leaves annoying stains. Messes are such a hassle to clean up in your bathroom.

Conclusion

It’s okay to be nervous about turning your hair blue, but you can rest assured that the products on this list are gentle. You can experiment with this playful color without committing full-time as the dyes fade out gradually and gracefully. So, if you’ve always wanted a bold feisty color, I suggest you give blue a try.
