Protein vs Deep Conditioning Hair Treatment – Which Do I Need?

In this article, we look at how you can repair damaged hair with protein vs deep conditioning hair treatments and how you can identify which treatment is right for you.

Taking good care of your hair can be a difficult task and repairing damaged hair can be a bit of a nightmare.


Hair straightening and other heat styling methods can cause split ends and frizzy locks and it can often be hard to figure out how to restore your hair’s natural health.

There is a big difference between a protein treatment vs moisturising deep conditioning hair treatment. A protein treatment helps to restore damaged hair from heat styling and a moisturising deep conditioning hair treatment improves hair strength and elasticity by balancing water levels in hair fibres.

The key to healthy hair is, therefore, a perfect balance between protein and moisture and this can be hard to maintain.

Pollution, hair products, and heat styling all contribute towards damaging your hair but with the right routine, you can easily get back on track.

Why Does My Hair Need Protein?

Hair has three important components: the cuticle, the cortex, and the medulla.

The medulla is more present in coarse hair and absent in fine hair. Asian hair, therefore, has more medulla than Caucasian hair.

The cortex makes up the majority part of the mass of hair.

This mass contains a large amount of keratin which is essentially protein and this is mainly what your hair is made of.

The components within the cortex also determine whether your hair is straight or curly.

The cuticle is the outer layer of the hair shaft and is made up of overlapping scales, like tiles on a roof.

The cuticle is thicker in Asian hair, less thick in Caucasian hair, and very thin in African hair. African hair is therefore much more prone to breakage.

Because your hair is mainly made up of protein, you need to ensure that you are following a hair routine that prevents protein loss as well as damage caused by heat styling, chemical treatments as well as environmental factors.

When your hair is damaged, the cuticle becomes weak and exposes the cortex. This leads to loss of protein which in turn causes fiber fractures and split ends.

Can I Have Too Much Protein In My Hair?

Yes, too much protein is commonly seen and is also known as being protein sensitive.

If you’re just starting out on your Curly Girl Method journey, you may be going through the transition phase and trying new products.

Many hair products contain protein because of the fact that damaged hair often leads to protein loss.

Using too many products with protein can cause an overproduction of keratin.

The balance between protein and water is essential for healthy hair and if you suffer from protein-sensitive hair, you would need a hydrating deep conditioning hair treatment vs a protein treatment.

Check out my easy guide to the Curly Girl Method.

Why Does My Hair Need Moisture?

According to the NCBI, Hair strength depends on cuticle integrity and the amount of water in the fibers.

Moisture is important to maintain healthy hair as it keeps it hydrated and helps retain shine and prevents dryness.

Without water, your hair becomes dry and brittle and much more prone to breakage.

The protein and water in your hair actually go hand in hand in order to maintain optimal health.

Water molecules bind with protein and so with the right balance of both, protein enables moisture to penetrate.

However too much protein will cause your hair to break and block hydrating products and water from penetrating.

Is There Such A Thing As Too Much Moisture?

Absolutely. Too much moisture in your hair can lead to hygral fatigue which is repeated swelling and drying of hair.

This can cause just as much damage as too much protein. It is however quite common to experience hygral fatigue, especially if the outer layer of your hair, the cuticle, has already been damaged.

It is, therefore, easier for water to penetrate and cause swelling.

To combat this, you would need a protein treatment vs a hydrating deep conditioning hair treatment.

Protein Treatment Vs A Deep Conditioning Hair Treatment

There are certain tell signs of when you will need a protein treatment and when you will need a deep conditioning hair treatment.

Moisture Overload

Lack of protein could cause the following:

Your hair feels limp and stretchy

A key sign of protein deficiency is when your hair feels limp and stretchy.

It might feel like your hair has lost its gloss and shine and it’s not reacting to any products you use such as gel or mousse.

You have color treated hair

If you have colored your hair in the past, there’s a high risk of protein loss.

This is because the chemicals in hair dye penetrate the cuticle and affect the cortex of your hair strands.

These chemicals can alter the chemical balance of the cortex and cause fibre damage which is held together by protein.

Curls have stopped forming

If you’re a curly girl and you’re experiencing a lack of bouncy curls, you may need a protein treatment. Your hair

Hair breakage

Hair will obviously become damaged due to a number of factors, but the fact that you are experiencing hair breakage is a good sign that you may be in need of protein.

If you have split ends and your hair easily snaps it could be time to try a protein treatment instead of a deep conditioning hair treatment.

Hair feels too soft

If you suffer from hygral fatigue, your hair is absorbing too much water.

The absorbance itself is not a problem, but hygral fatigue means that there is repeated swelling and drying and this causes your hair to stretch and become weak.

In order to combat hygral fatigue, you’ll need a protein treatment to help seal the hair cuticles to prevent water and harmful products to enter the cortex.

It can sometimes be difficult to differentiate between protein sensitivity and hygral fatigue.

This is because your hair doesn’t feel or look healthy and so the main symptoms are sort of the same; split ends, stringy hair and curls that won’t really form.

Protein Overload

There are few key signs you can look out for if you think you’re suffering from protein overload and that you might need a deep conditioning hair treatment:

Dry and brittle hair

If you suffer from protein overload, your hair will feel dry and brittle. It has lost its shine and seems hard to style.

Hair breaks easily

Whenever your hair is unhealthy, it’s far more likely to snap.

If your hair is very dry and hair strands seem to break very easily, then you would benefit from a hydrating deep conditioning hair treatment to get rid of excess protein.

Curls don’t stretch

You might be following the Curly Girl method and after a while, your curls don’t seem to stretch anymore.

This is another sign that your hair is lacking moisture.

Hair feels like straw

If the texture of your hair has changed and it now feels strawlike, you need a deep conditioning hair treatment.

Strawlike hair is a key sign that your hair is suffering from protein overload and you will need to balance out the ratio.

If your hair also feels frizzy straight after a protein treatment, you’ll know that protein is not the solution to your hair troubles.

Curls won’t clump together

If your curls won’t clump together there’s a high chance that you are lacking moisture.

When I first started my Curly Girl journey, I had good results from the products I was using.

However, after a month my curls stopped forming as well and my hair looked dull and dry.

It didn’t feel soft, but rather stringy and coarse. This is how I knew that I was protein sensitive rather than suffering from hygral fatigue.

This is my hair when I first started the Curly Girl Method:

Protein vs deep conditioning hair treatments

This is around six weeks in:

Protein vs deep conditioning hair treatments

As you can see, my curls were no way as bouncy and formed as when I first started on my Curly Girl journey. My hair felt brittle and dry and it had lost its shine.

Here’s another photo of my hair when it was out of balance:

Protein vs deep conditioning hair treatments

And this is what happened when I balanced out the protein with an apple cider vinegar rinse:

Protein vs deep conditioning hair treatments

I would always recommend that you do an apple cider vinegar rinse first if you suspect you’re suffering from protein overload.

The apple cider vinegar balances out the PH in your hair and as you can see from my photos, produced amazing results.

Simply add a few spoonfuls of apple cider vinegar to 200ml of water and then soak your wet hair in the mixture.

Leave for a few minutes and then rinse out with a non-protein conditioner such as the Faith in Nature Aloe Vera conditioner.

You should also try switching out your products with a protein-free conditioner.

How Often Do I Need To Treat My Hair With Protein Vs A Deep Conditioning Hair Treatment?

Protein Treatment

If you are in need of a protein treatment, you should start out by treating your hair once a week for three weeks followed by conditioner.

Incorporate a weekly treatment into your regular routine and make sure you give the treatment enough time to work.

I usually recommend thirty minutes and I would also recommend using a deep conditioning heat cap such as this one I found on Amazon.

A deep conditioning heat cap will help accelerate the process as heat allows for the product to penetrate your cuticles much easier.

If you do not see any improvement after three weeks, you should consider changing your routine. So think of the way which you wash your hair, how often you wash your hair and what other products you use.

A protein treatment, if applied correctly, should in most cases produce results.

If you think you may have misdiagnosed your symptoms, you could try a hydrating deep condition but I often find that if you take a close look at your routine, you’ll find the mistakes and correct them.

Deep Conditioning Hair Treatment

If you are in need of moisture, continue with a weekly treatment for as long as required.

In general, your hair needs to be properly hydrated in order for it to return to its original healthy state.

Use a deep conditioning treatment the same way as you would a protein treatment, so leave for thirty minutes and utilise a heat conditioning cap for maximum effect.

Don’t over-condition your hair and don’t sleep with a deep conditioning treatment as this could make your hair too soft and cause further breakage.
