Is Keratin Shampoo Good for Hair?

Keratin is a popular ingredient in nourishing shampoos, as well as other hair care products including oils, creams, conditioners and hair masks. But is it really as good as everyone says? And if so, how exactly does it work?

How does keratin shampoo work?

First, it’s important to know that keratin is a natural protein found within our bodies. It plays a vital role in the maintenance of our skin, hair and nails, which is why keratin shampoo can be so impactful.

Keratin shampoos can help to repair and maintain damaged hair – that’s because the keratin in the shampoo can fill in the gaps where the keratin in your hair has become damaged. It’s a like-for-like repair job. Just as you would use the same bricks to repair a damaged wall, keratin shampoo uses the same building blocks that make up your hair.

The outer layer of your hair is made up of overlapping scales of keratin. When damage occurs, these scales become raised, which contributes to that feeling of roughness common to damaged hair. Keratin shampoos help to smooth the scales back down and repair roughness, resulting in improved hair texture and appearance.

As you can imagine, having the right levels of keratin in the body helps to maintain happy, healthy hair. Unfortunately, sometimes you can have a keratin deficiency – in other words, you don’t have enough keratin to support healthy skin, hair and nails.

This can sometimes occur as a result of a biotin deficiency. Biotin, another key ingredient in many hair care products, is a substance that helps with the production of various amino acids – which, in turn, are the building blocks of proteins like keratin.

Keratin shampoo can be beneficial whether you have a deficiency or not – but if you do happen to be low in naturally-occurring keratin, a keratin shampoo can help to boost your levels to keep your hair healthy.

Is keratin in shampoo good for hair?

In short, yes – keratin shampoo can be highly beneficial for the hair, as can other at-home products containing keratin, like conditioners or hair masks. Unlike regular shampoos, keratin doesn’t just clean your hair – it actually strengthens it to make it more resilient to damage.

Strengthening and repairing the hair

Keratin shampoos do this by repairing the outer cuticle – in other words, the outermost layer of each hair strand. As well as strengthening the structure of the hair, this helps to improve the strands’ elasticity, making them more flexible. This means your hair strands are less likely to break or develop split ends – a win for healthy-looking hair.

Because of this, keratin shampoos can be especially effective if you have damaged hair – whether that’s from sun exposure, excessive brushing, heat styling, bleaching or air pollutants. By strengthening the hair, keratin shampoos can help to return damaged hair to a healthier state.

Relieving frizz

Another key area where keratin shampoos can help is frizz. Frizz happens when dry hair searches for moisture in the air around it – so when the humidity is high, it puffs up to absorb as much as it can. Keratin shampoos help to moisturise your hair strands so this doesn’t happen, keeping your hair sleek and soft.

Relieving hair roughness

As well as minimising frizz, this moisturising action helps to smoothen your hair strands so they’re less prone to tangling and breakage. This can make your hair easier to manipulate when styling.

Smoother strands also reflect light better, leaving your hair with a glossy appearance – helping to prolong the life and vibrancy of colour treatments and keep you looking your best between salon visits.
