Yes. Developer on its own does lighten hair, and the technique is often safer and gentler than using bleach products. Developers, also known as activators, are an important component in the hair dying process.

It lifts the hair cuticle, allowing dyes to penetrate deep into the core and leave bright, permanent color. Different developers offer varying amounts of lift, defined as “volume,” based on how much hydrogen peroxide they contain:

  • 10 volume = 3% peroxide
  • 20 volume = 6% peroxide
  • 30 volume = 9% peroxide
  • 40 volume = 12% peroxide

In most cases, people don’t use a 10 volume developer to lighten their hair. With only a 3% peroxide content, it doesn’t have the power to lift more than a couple of shades. In most cases, people only use 10 vol developers to deposit color. 

If you want a very subtle brightening effect, you may want to consider treating daily with a 10 developer for a week or so. You can slowly and progressively lighten your hair without worrying about excessive damage to the cuticle.

Using Developer to Lighten Hair

Using a developer on its own is an easy DIY solution for lighter hair. Depending on how many levels you want to lift, you can choose between a 10, 20, or 30 volume developer. Simply work the product into your hair and allow it to sit for the recommended time.

Always make sure to moisturize your hair with a deep conditioning treatment or hydrating mask afterward to protect strands against damage. If you find that developer on its own isn’t enough to lighten your hair, you may want to try combining it with baking soda.

The peroxide reacts with the sodium bicarbonate to lift and lighten more effectively. You can also go the more traditional route and mix developer with bleach powder for a more noticeable effect.

Things to Consider

While developers are typically safer and gentler than lightening with bleach, using them doesn’t come without risks, so it’s essential to consider the risks of using developers before adding them to your hair care routine.

  • While developers are gentler than bleach, they will still damage the cuticle and lead to frizzing.
  • Leaving a developer on for longer than recommended can cause severe damage to your hair.
  • It’s best to use developer only on healthy hair. If you have damaged hair, you may want to grow it out before trying a developer treatment.
  • It’s always a good idea to perform a patch test on your skin to ensure you won’t have a reaction.
  • You should also perform a strand test to check what the resulting color will look like and ensure your hair is compatible.
  • Remember that while the results of a developer treatment will be subtle, they are permanent. If you don’t like the results, they can be difficult to fix without causing further damage.

Frequently Asked Questions

Here, we’re going to go over some of the most common questions people have when lightening their hair with a developer.

What happens if you put just a developer in your hair?

If you put a developer in your hair without any additional bleach, it will gently lift and lighten the color without causing too dramatic of a change. If you’re worried that bleach is too harsh or will lighten your hair too much, you may want to try using developer by itself.

Developers used alone will not change the color of your hair. While it may lighten strands, they will remain close to their original tone. If you want to dye your hair a different color, whether lighter or darker, you need to use a developer in combination with color.

How can I lighten my hair with a developer at home?

It’s easy to lighten your hair with a developer from the comfort of your own bathroom. Remember to wear disposable gloves to protect your hands when working, as developers can be harsh on the skin.

It’s essential to choose a developer that’s appropriate for your hair type. When in doubt, always go with something gentle before working your way to more intense lightening treatments. Apply developer to damp hair according to the directions, then allow it to sit for up to 30 minutes. It’s a good idea to check the color at five-minute intervals to ensure you don’t lighten too much.

Can you remove hair color with a developer?

If you don’t like your new color after dying your hair, you may be able to do some damage control with the help of a good developer. Mixing a 10 to 20 developer can help remove semi-permanent color, while volume 30 products can strip away permanent dyes.

How long can you leave a developer on your hair?

You shouldn’t leave a developer on your hair for any longer than 30 minutes. After that point, the peroxide may cause irreparable damage to hair strands and even burn the scalp. Ten to twenty minutes of treatment yields bright, natural-looking results for most people.

Should I use a 10 or 20 developer?

The volume of the developer that you use will depend mainly on how many levels you want to lighten your hair. If you’re just looking for a bit of lift, you should use a 10 developer with a low peroxide content. A 20 developer, on the other hand, will lighten your hair up to two levels for a more dramatic effect.

So, Does Developer Lighten Hair?

So, does developer lighten hair? The short answer is yes, it does. Developers offer a safe and gentle way to create an all-new look if you want to lighten your hair. With the right volume developer, you can achieve a natural-looking lift without worrying about excessive damage.
