Best Protein Treatment For Bleached Hair

You’ve heard it dozens of times – bleached hair is usually synonymous with damaged hair.

Fortunately, there are ways to repair the damage dealt by the bleaching process.

The most effective and reparative of these are protein treatments that give you back your hair’s strength, bounce, and softness.

But what’s the best protein treatment for bleached hair?

Benefits Of Using Protein Treatments

Protein treatments have exceptional reparative properties, so they’re perfect for damaged hair that is dry and brittle.

Proteins restore and restructure the hair to make it more resilient.

That’s why many hair care products labeled “for damaged hair” contain proteins.

When hydrolyzed proteins sink into your hair cuticle, they add a protective layer, making each strand sturdier and less prone to breakage.

Since they fill in gaps and holes in the cuticle, they make your locks smoother too.

Most protein treatments are rich in vitamins and nutrients the hair needs for health to be restored, such as vitamins B and E.

These work hand in hand with proteins to ensure you get your elasticity and bounce back in your tresses.

When your hair has enough protein, it looks full and luscious, leading to gorgeous volume and movement.

If your hair has been limp, lifeless, and stringy, it’s probably begging for some protein.

Protein is also responsible for hair’s elasticity, or how it holds a curl pattern.

Healthy hair should be able to hold curls or waves well.

If your hair always falls flat when you style it, it might need extra protein.

In a nutshell, proteins allow your hair to go from parched, brittle, and straw-like to soft, silky, and strong.


Why Does Bleached Hair Need Protein Treatments?

The long and short of it is that hair is protein in itself, so building up damaged hair with more protein repairs the hair and makes the cuticle stronger.

Every strand of hair is made of keratin, a fibrous protein.

And when you damage your hair with heat styling or chemical treatments like bleach, parts of the cuticle lift and open up to release our natural color.

This breaks down the keratin and leaves gaps in the cuticle, making your hair thin, brittle, and dry.


The hair is overly porous

Bleaching amps up your hair’s porosity, or how many gaps and holes it has in the cuticle because of chemical damage.

The more porous your hair, the harder it is to retain moisture, which can account for why your hair is so dry after bleaching.

The hair also becomes extremely weak, which is why it feels so dry and lifeless.

The bonds of your hair can break, leading to split ends.

You may even notice that your hair can’t hold your natural hair texture properly anymore.

The best way to build your hair back up and restore its health is by replenishing your strands with the protein they lost.

And how do you do that?

By using your trusty protein treatment, of course.

Proteins fill in those gaps – at least temporarily – to make your hair stronger and “thicker” so it can get that healthy bounce and glow back.

It also helps your hair retain moisture for longer so that your hair can stay soft and hydrated again all day long.

Because proteins seal the cuticle and fill in those rough gaps, you’ll feel your hair become super soft and easy to manage during styling.

It will also become easier to detangle because it’s so smooth.

That’s the magic of protein treatments; they press reset on your hair, so it feels brand new.

It’s also a bright idea to use a protein treatment right before you bleach your hair.

Since extra protein makes the base of your hair stronger, it should be able to take the chemical damage like a champion, and the after-effects might not be so horrible.
