Does your hair need a protein treatment?

Do you have limp hair without elasticity? Then your hair most likely needs a protein treatment. Read here how to recognise that you need such a treatment.


If your hair feels weak and just hangs limp, this could be a sign that your hair needs a protein treatment. Protein helps to rebuild and strengthen hair. Today we'll show you the signs that your hair needs protein.

What exactly does protein do in the hair?

Protein in hair plays a crucial role in the structure and health of hair. Hair is mainly made of keratin, which is a protein-rich material. The protein molecules in hair strengthen the hair structure by smoothing the outer layer of the hair, called the cuticle, and repairing damaged areas. This can help reduce frizz, improve elasticity and make hair look healthier and stronger overall. Using hair care products that contain proteins could help damaged hair repair its structure.

How does a protein deficiency develop?

A protein deficiency in the hair can occur in several ways. These are the different causes:

  • Nutrition: A lack of protein-rich foods in the diet can lead to a lack of protein in the hair. Hair needs proteins, especially amino acids like collagen and keratin, to grow healthy and stay strong.
  • Environmental factors: Excessive heat treatment, aggressive hair treatments, sun exposure and pollution can damage the hair and cause the proteins in the hair to break down.
  • Chemical products: The use of strong chemicals in hair care products can cause proteins to be leached from the hair, leading to protein deficiency.

So to avoid a protein deficiency, it is important to eat a balanced diet, treat the hair gently and use good hair care products.

Protein deficiency hair: signs

But how can you tell if your hair is protein deficient? The following signs will help you know if your hair needs more protein:

A lot of frizz in the hair

If your hair tends to frizz quickly, for example when the air is just a little humid, it may be because your hair lacks the necessary protein. The hair has small gaps that immediately absorb the moisture - this is how split ends develop. With a protein treatment you can fill these gaps. The hair is strengthened and less prone to frizz.

No elasticity in the hair

Elasticity in the hair is very important, otherwise it breaks off much too quickly. If your hair has lost the natural structure of the curls, this is a sign that it has lost its bounce. You can test the elasticity of the hair by pulling one out and stretching it. If the hair can be pulled apart and then bounces back to its original shape, then your hair has enough elasticity. If the hair breaks, it is in desperate need of a protein boost.

Stringy hair

Another sign of protein deficiency in the hair is when the hair hangs stringy and limp. With the protein boost, you strengthen the hair from the inside and give it more grip.

Gum-like hair

If your hair feels like rubber or even sticky, then the hair structure is severely damaged. This can be the case after bleaching. If the hair can be pulled apart like chewing gum and you have a complete tuft in your hair afterwards, everything that is broken must be cut off. Afterwards, you can treat the hair with protein to rebuild it.

Freshly dyed hair

The chemicals in hair colour can damage your hair structure. To create a better base for the colour, use a protein treatment to strengthen the hair before and after colouring.
