Do you want stronger and healthier hair? Your hair is exposed to lots of things every day such as dyeing, blow-drying, various styling products... It can take a lot of wear and tear on the hair in the long run if you want to maintain your strong and healthy hair. Here, protein treatments can be a fantastic way to give your hair an extra boost. From improved elasticity to less breakage and fewer split ends, protein treatments for hair can help you achieve the look and feel you want.

Protein for hair is essential because it provides the building blocks your strands need to repair damage and maintain strength. Regular protein treatments for hair can address common concerns like brittle ends and dullness.

Not only do they strengthen hair from the inside out, but they can also protect your hair from environmental damage, leaving it shinier and more radiant. In this blog post, we'll discuss why protein treatments are so beneficial for healthy hair, how often you should get them done, and what type of treatment is right for your specific needs. So if you want to take your mane to the next level, read on!

What is a protein treatment for hair?

A protein treatment for hair is a type of in-depth hair treatment designed to strengthen and repair the hair. It usually contains proteins, amino acids and other caring ingredients that help rebuild the natural structure of the hair strands.

Protein treatments for hair are ideal for dry, brittle or damaged hair as they help restore elasticity, reduce breakage and split ends and improve overall texture and softness. These treatments typically contain hydrolyzed proteins such as keratin, wheat protein, silk protein and collagen, which provide essential nutrients for healthy hair growth.

A protein treatment for hair can have many different shapes and sizes. You can actually make a homemade protein hair treatment quite simply, but you can also get a specially developed protein hair treatment adapted to your hair. I review my favorite protein hair routine tips further down in this article.

Why are proteins important for hair?

Proteins are an important component of hair, as they provide strength and elasticity. Proteins are made up of long chains of amino acids, which give hair structure and help it stay strong and healthy. The protein keratin is particularly important for hair. In fact, our hair is mainly made up of the protein keratin, so this protein is particularly important. It helps to give strength and structure to our hair. You can read more about keratin for hair here 

Without enough protein in the hair, it can become dry, brittle and prone to breakage and split ends. This is why it is so important to eat a balanced diet high in protein to maintain healthy hair.

Other proteins that are particularly beneficial for hair include wheat, collagen and elastin, which provide flexibility to the hair shaft, cysteine, which helps strengthen the hair shaft, and keratins, which promote healthy cuticle layers. All these proteins play an important role in keeping our hair vibrant, shiny and healthy.

What does a protein treatment do for your hair?

A protein treatment for hair works by nourishing and strengthening the hair by supplying it with important proteins that it may be lacking. The proteins penetrate the hair shaft and fill any gaps in the cuticle layer, which strengthens the structure of the hair shaft. This helps reduce breakage and damage while leaving hair softer, smoother and shinier.

Protein treatments also enhance elasticity, making hair more resilient to breakage. They are particularly beneficial for chemically treated or heat-damaged hair, as they help rebuild and protect weakened strands.

In addition to repairing existing damage, protein treatments for hair can increase elasticity, helping to prevent further damage caused by styling tools or exposure to heat or chemicals. In addition, they help to maintain the moisture balance in the hair so that it does not become too dry or brittle. The proteins also protect against environmental stress factors such as UV rays. 

Ultimately, regular use of a protein treatment helps keep your hair healthy and looking great.

How often should I use a protein treatment for hair?

A protein treatment for hair should be used once every two weeks. It is important to use a protein hair treatment as part of your regular hair care routine, as proteins are important for healthy, strong and nourished hair. When using a protein hair treatment, it is best to apply the product from the ends of the hair up towards the scalp. Let the product work for approx. 15 minutes before rinsing thoroughly with warm water. If you have very damaged or weak hair that needs more intensive rebuilding, you can increase the frequency to once a week, but not more than that, as overusing protein treatments can cause damage instead of repairing them.

It is also incredibly important to always use protein treatments for hair after shampoo and, more importantly, to finish with a conditioner. It is best if these products contain lots of moisture and care. This is to ensure the hair is not fragile afterwards.

How to test if your hair needs protein

One way to test if your hair needs protein is to do a protein-moisture balance. This is done by wetting a strand of hair and stretching it out. If the hair shaft stretches more than usual and breaks easily, it indicates that your hair has a low protein content and needs extra nourishment.

To further test for protein deficiency, you can perform an elasticity test. In this case, simply pull one of your hairs gently between two fingers and release it again. If the strand returns to its original state tightly, your hair's elasticity is healthy; but if the strand remains stretched after being released, it indicates that your hair needs protein.

Additionally, another sign that may indicate that your hair needs extra protein is split ends or knots with single strands throughout the hair shaft. All of these signs can be indicators that you should consider adding a protein treatment to help strengthen and nourish your locks from within.

Does my hair need protein or moisture?

Determining whether your hair requires protein or moisture is essential for maintaining its health and appearance. Both things play distinct roles in hair care.

Signs your hair needs protein:

If your hair experiences increased breakage during styling or combing, lacks elasticity by stretching without returning to its original shape, appears dull and lifeless, or frequently develops split ends along the hair shaft, it may indicate a need for more protein.

Signs your hair needs moisture:

Conversely, if your hair feels rough and brittle to the touch, exhibits excessive frizz, especially in humid conditions, becomes easily tangled and difficult to manage, or appears dull and lacks natural luster, it likely requires additional moisture.

Assessing your hair's needs:

To determine if your hair requires protein or moisture, perform a simple elasticity test. Gently stretch a damp hair strand. If it stretches and returns to its original shape, your hair has adequate protein. If it stretches without bouncing back, it may need more protein. If it breaks easily, it likely needs moisture.

Understanding your hair's specific needs allows you to choose appropriate treatments, ensuring optimal health and appearance.

FAQ about protein for hair

Are protein and keratin the same thing?

Protein and keratin are related, but they are not the same.

Proteins:

Proteins are large, complex molecules made up of long chains of amino acids. They perform a wide range of functions in the body, including structural support, transporting molecules, and catalysing biochemical reactions.

Keratin:

Keratin is a type of protein that is an important component of hair, skin and nails. It is particularly known for its strength and protective properties. Keratin is a fibrous protein that helps protect cells from damage or stress.

While proteins in general contribute to various functions, keratin is specialized for structural integrity and resilience, particularly in hair.

Context:

Keratin is a specific type of protein that plays a key role in building hair shafts and other keratinised structures in the body. Protein hair treatments often contain keratin to strengthen and repair hair.

When does hair lack protein?

Hair can lack protein for several reasons, and it's important to recognise the signs of protein deficiency in order to give your hair the right care. When hair lacks protein, it often becomes limp and lifeless, meaning it lacks elasticity and falls flat, even after styling. Other signs of protein deficiency include breakage and split ends, where the hair breaks easily and has many split ends, indicating a weakened hair structure. Lack of volume can also be a sign, as hair feels thin and lacks fullness.

Curly hair that lacks protein loses its natural shape and definition, which can be a clear sign of protein deficiency. Curly hair relies heavily on protein for maintaining its bounce and form. When protein levels are low, curls may appear stretched out or undefined, signaling the need for a targeted protein treatment for hair.

Hair can also feel dry and coarse, indicating that it lacks the necessary proteins to keep it smooth and soft. Finally, abnormal hair loss can be a sign that the hair lacks protein and has become damaged.

Is it good to put eggs in my hair?

Yes, adding eggs to your hair can be beneficial as eggs contain many nutrients that can improve hair health. Eggs are rich in proteins that can strengthen hair and improve its structure. They also contain fatty acids that moisturise and make hair softer and shinier.

Benefits of using eggs in hair:

  • Strengthens hair: Protein in eggs helps repair damaged hair and strengthens the hair strands.
  • Moisturises: The fatty acids in eggs can help moisturise and soften hair.
  • Improves shine: Eggs can make hair more lustrous and healthy-looking.

How to use egg in your hair:

  1. Beat an egg and apply it to damp hair.
  2. Massage it well into the scalp and hair.
  3. Leave it on for 20-30 minutes.

Rinse thoroughly with cold water and then wash with a mild shampoo.
Eggs can be particularly beneficial for dry and damaged hair, but can be used by all hair types to improve hair health and appearance.
