Can You Use Toothpaste To Lighten Your Hair?

Written by Ramona Sinha

There are always some crazy hair hacks going viral on the internet. The latest on the block is using toothpaste to lighten the hair. While this is not a scientifically proven way, many beauty vloggers are going crazy over this weird hair-lightening hack. Scroll through this article to find the truth behind this claim and learn if toothpaste can bleach or lighten your hair.

Does Toothpaste Lighten Your Hair?

There is no definite answer to this. Toothpaste may (or may not) alter your hair color a bit, depending on the type and formula.

Many toothpaste brands claim to whiten your teeth as they contain hydrogen peroxide. This ingredient is also used as a hair lightening agent in bleaches and dyes. In salons, hair colorists use hydrogen peroxide solution to lighten or bleach the hair before coloring.

This is one reason why people put toothpaste on their hair strands to lighten or bleach them. Does that mean using any toothpaste with hydrogen peroxide can lighten the hair? Not necessarily.

First things first, toothpaste is not meant to be applied to the hair. The concentration of hydrogen peroxide required for teeth whitening is way too low than you need for bleaching. Hence, leaving toothpaste on your hair for long may slightly fade the hair color, but the results may not meet your expectations.

Moreover, it is not safe to apply toothpaste to the hair. Most toothpaste formulas contain baking soda and other antibacterial ingredients that may dry out the hair and cause breakage.

While applying toothpaste to the hair is messy, removing dry toothpaste from the hair is tough. In the next section, we discussed easy ways to remove toothpaste from your hair.

How To Remove Toothpaste From Your Hair

  • Separate the hair section with dried toothpaste and clip it away from the rest of the hair.
  • Use warm water to soften the dried toothpaste and comb the section gently with a wide-toothed comb to remove the product
  • Shampoo your hair. Leave it on for a few minutes to dissolve toothpaste residue.
  • Wash off the shampoo and repeat 1-2 times if the hair feels sticky.
  • Detangle your hair with a wide-toothed comb after washing.

Conclusion

Toothpaste with hydrogen peroxide may fade your hair color up to some extent, but the results depend on the formula. Applying toothpaste to the hair is messy and may also damage your hair. Moreover, other ingredients in the toothpaste formula may also irritate the scalp. It is better to use hair bleach or take professional help to lighten your hair.
