Do you plan on lightening your hair? Or maybe you’re just curious about the process. Either way, we’ve you’ve come to the right place!

In this article, we’ll dive into the world of hair lighteners. We’ll review what they are and how they work and help you learn how you can lighten your hair safely. Let’s jump right in!

What Is a Hair Lightener?

Hair lighteners are used to lighten the natural pigments in your hair. They break the pigments down into such small parts that they’re not as clearly visible. So, when light shines through your strands, it reflects through the empty space and leaves your hair looking noticeably lighter. 

But unlike bleach, lighteners don’t destroy or remove your natural pigments. They just make them less visible. Hair lighteners can only subtly lighten your locks, so they aren’t very helpful for naturally dark strands.

However, they are significantly gentler than bleach. In fact, hair lighteners are so non-damaging that you can use them nearly every week.

Are Bleach and Hair Lighteners the Same Thing?

Although hair lighteners and bleach both lighten hair strands, they are not the same. Hair lighteners are more gentle on the hair cuticle and can only lighten your hair slightly.

They only affect your natural hair color and can’t remove or alter artificial dye pigments. Most hair lighteners are geared towards hair that is already primarily light, while bleach is suitable for all hair shades.

And unlike hair lighteners, you can use bleach on both natural and previously colored hair. When you bleach your hair, the outermost layer–or cuticle–is raised.

Then, the bleach enters your strands and weakens the bonds holding your pigments in place.

Once the bonds are weakened, they break, and the pigments are washed out of your hair. Through this process, bleach is able to lighten your hair dramatically. But unfortunately, it can also cause severe damage, hair loss, and chemical burns.

Is Lightener Bad for Your Hair?

Although hair lighteners aren’t as damaging as bleach, they can negatively affect your strands. If you use them too frequently, you might notice that your hair is drier and more breakage-prone.

Luckily, the damage caused by hair lighteners is mild. You can usually prevent or reverse it with regular deep conditioning and strengthening treatments

Can You Lighten Your Hair Without Bleach?

While bleach and lighteners are some of the most effective methods of lightening your hair, they are far from the only ones. Here are some other bleach-free ways to lighten your strands.

Use a Saltwater Spray

If you’ve ever spent a day at the beach soaking in the sun’s rays, you may have returned home to find that natural highlights have developed.

Well, this convenient hair-lightening solution brings the beach to you! Saltwater is a powerful hair lightener because it can lift your hair’s cuticle and let the sunlight in. 

To give this method a try, mix a tablespoon or two of sea salt into a spray bottle filled with warm water. Shake well to ensure everything is evenly distributed.

Spray the saltwater solution onto your hair and ensure each strand is fully saturated. Then, go outside and sit in the sun for ten to twenty minutes. 

After a more dramatic lightening effect? You can sit in the sun for as long as one hour. Once your time has passed, rinse your hair well with cool water.

Wash and condition your hair like normal, and examine your new, lighter shade. You can use a saltwater spray once a week until you’re happy with the results. Don’t forget your sunscreen!

Apply a Beer Rinse

Who knew that leftover beer in your fridge could give you the lighter locks you’ve been craving? Beer is slightly acidic and gently nudges your hair open. Once your cuticles are open, sunlight can enter your strands and lighten the natural pigments inside.

As a bonus, beer contains a blend of vitamins and minerals that nourish your hair. Keep in mind that this method is best suited for natural blondes. On brown hair, a beer rinse can uncover harsh orange tones.

Want to give it a try?

Once or twice a month, pour two to three bottles of beer into a bowl and leave it on the counter. Wait for a few hours until the beer is no longer carbonated. In the meantime, shampoo your hair like usual. 

Once your hair is clean, pour the flat beer directly onto your hair and soak up some sunlight for around half an hour.

After your time is up, head back inside and rinse the beer from your strands. Follow up with your favorite conditioner, and check out your new, lighter locks.

How Long Do You Leave Hair Lightener In?

There’s a common misconception that leaving lighteners in your hair for an extended length of time will help it work better. You should always follow the directions on your specific hair lightener.

You risk developing breakage, dryness, and hair loss if you leave them on for any longer than that. Each hair lightener is different.

While some are meant to be washed out, others are left in for days at a time. So always play things safe by sticking with the recommended amount of time.
