101 Guide to Protein Hair Care

by Naturiam Store in News

Proteins are made from the polymerization of amino acids that are linked to each other by α-peptide bonds. There are a total of 20 amino acids associated with the structure and function of the human body. The body uses dietary proteins and amino acids to resynthesize proteins in the body. In our body, 9 amino acids are essential while the other 11 are not. [1]

Hair is described as a filamentous structure composed of proteins, particularly keratin. Keratin has a helical shape and has two types of fibers in the hair. Type I keratin fibers have acidic amino acid residues while type II keratin fibers have basic amino acids. Keratin fibers are present in the cortical cells of the hair. In people with straight hair, these cells are arranged symmetrically, while in In people with curly hair , these fibers are arranged in a non-symmetrical manner. [2]

Do DIYs with nutritious proteins serve as protein hair care?

Many people use homemade protein hair masks made from healthy foods such as eggs, avocados, and other protein-rich foods. While protein supplementation is helpful for growth and health Hair, these homemade protein hair treatments are not effective. Proteins are large and unable to adapt to the hair shaft.

The inability of these proteins to penetrate the hair shaft contributes to the ineffectiveness of this type of homemade protein hair mask. However, hydrolysis of the proteins can make them smaller and more penetrating into the hair. One study showed that hydrolyzed egg white proteins can penetrate deep into the hair . [3]

Therefore, homemade protein hair masks do not serve as effective hair protein treatments. Substances such as mayonnaise make hair shinier and softer due to their fat content. [4]

Are chemical protein treatments real protein treatments?

Chemical protein treatments are NOT true protein treatments. Instead of nourishing the hair's protein content, chemical protein treatments break the chemical bonds in the keratin protein. These treatments alter the disulfide bonds between cysteine ​​amino acids.

Protein treatments for curly hair cause permanent straightening of the hair by disrupting the normal structure of the hair. Protein hair straightening treatments use alkaline creams that include potassium hydroxide, sodium hydroxide, lithium hydroxide, or guanidine hydroxide. While these protein treatments permanently straighten the hair, these chemical relaxers cause immense damage to the hair shaft. [5]

What is real protein hair care?

Given that the protein hair care Since homemade and chemical protein hair treatments are not ideally effective, the question arises: what is real protein hair treatment? Lower molecular weight or smaller proteins are better able to penetrate the hair shaft than larger proteins, such as those used in DIY treatments.

Hydrolyzed proteins are smaller in size and can therefore nourish and benefit the hair. Hydrolyzed keratin fills the gap in damaged hair and improves the mechanical strength and elasticity of the hair. [6, 7] These protein treatments are useful in meeting the hair's protein needs, achieving softness, increasing mechanical strength and increasing the diameter of the hair shaft. [7]

Unlike people with straight hair, people with curly hair are more likely to straighten their hair using temporary straightening tools or permanent chemical hair treatments. This leads to increased hair damage and protein loss for curly hair, making it more in need of a real curly hair protein treatment.[8] Some common questions related to hair protein care are listed below.[9, 10]

FAQs

Why use protein for hair?

Proteins are the main building blocks of human hair. Proteins are important for hair strength, hydration, and repair. Proteins also slow water loss, keeping hair hydrated and healthy.

What hair types need protein?

People with porous hair, dry hair, brittle hair, damaged hair, fine and medium hair, hair that looks “smaller” when wet can benefit from protein hair care.

How to use protein for hair?

For protein hair care, you can use shampoos or solid shampoo , protein styling gel real, natural masks with hydrolyzed proteins. Leave-in products containing protein can also be very useful for conditioning and nourishing hair. Proteins or protein-containing products for hair care include gelatin, collagen, keratin, amino acids, peptides, and hydrolyzed proteins such as: hydrolyzed wheat, oats, quinoa, corn, soy, and silk.

What is protein-hydration balance?

Protein-moisture balance can be thought of as the balance between stiffness and softness. Proteins provide stiffness/moisture while oils and conditioners promote softness. There must be a balance between emollients and proteins during treatment to ensure optimal hair health.

What are the signs that hair needs protein?

Signs that hair needs a protein treatment include loss of sheath, hair breakage, damaged hair, and a soft, cakey texture when hair is wet.

How often should you use protein?

The frequency of hair protein treatments depends on the porosity and thickness of your hair. The more porous and thinner your hair, the more protein treatments it needs. You can use a mask containing proteins every week. the low porosity hair and thick hair may only require protein treatment every 1 to 2 months.

Conclusion

Individuals must make wise decisions when choosing a true protein treatment for overall hair health. This treatment option includes hydrolyzed proteins, which are smaller and more penetrable. True protein treatment for curly hair does not require the use of chemical agents and does not alter the chemical bonding of amino acids in the treatment.

We offer a real protein hair care using hydrolyzed proteins and amino acids in our wide range of protein skincare products. This treatment is safer and more effective than the other two techniques, so one can opt for this protein treatment to maintain hair health.

The Science Behind Hair Porosity

With a consistent hair care routine, you can achieve healthy curly hair. Knowing and understanding what your hair likes and what to avoid is the best way to create the most effective hair care routine. For strong, healthy hair, the right products are essential. Hair is more complex than you think. It is made up of a protein known as keratin. Hair contains essential elements that combine to characterize it. This includes; hair texture (wavy, curly, or kinky), hair porosity, follicle size, hair shaft diameter, and thickness. Hair porosity is one of the important characteristics to consider for curly hair health. Hair porosity determines the degree of protection your hair needs, its ability to retain water, products, hair treatments, and how long it takes to lose water. This is regulated by the hair cuticle, which is the outer protective layer of the hair structure that allows water and other products to penetrate the inner layer of the hair. Think of the hair cuticle as a door that opens and closes. Table of Contents WHAT CAUSES HAIR POROSITY How to measure hair porosity Avoid the float test The most accurate way to test hair porosity: LOW POROSITY HAIR The characteristics How to Care for Low Porosity Hair MEDIUM HAIR POROSITY The characteristics HIGH POROSITY HAIR The characteristics How to Care for High Porosity Hair WHAT CAUSES POROSITY HAIR Hair porosity is primarily determined by genetics and hair care practices. Porosity can vary in different parts of the head and even across different lengths depending on hair grooming techniques that could alter and damage the hair cuticle. A damaged hair cuticle is chipped or torn, exposing the hair cortex of the inner layer of hair to damage and dryness. Those with textured hair, especially curly, wavy, or kinky hair, will naturally experience more wear and tear. Sebum (the hair's natural oil) takes time to travel down the hair strands to lubricate and coat the hair strands, making curly, wavy, and kinky hair more susceptible to damage. This leads to an increase in hair that becomes porous. How to measure hair porosity Avoid the float test It is commonly used to treat hair porosity, but it is inaccurate. Relying on the glass of water test to detect porous hair has been shown to give false readings. This is due to the surface tension of water – Water molecules stick together where air should meet water. Placing light objects like a single strand of hair will be like skin on water and float gently. Therefore, surface tension will counteract the weight and porous hair. Also, dry hair is buoyant in water, so hair and water have a similar density. The most accurate way to test hair porosity: Gas absorption  – Gas absorption determines the total pore volume, which corresponds to the holes in the surface. It measures how much of a given gas can be absorbed by hair, which is more porous and will absorb more gas. Hydration test/spray test – This is a qualitative assessment of the behavioral test that porous hair absorbs water much faster than non-porous hair. This is tested using clean, dry hair. High porosity hair should absorb water faster than low porosity hair, which would instead have visible water beads and take longer to dry. Dynamic Vapor Sorption (DVS) – Humidity has a significant impact on hair weight with qualitative recordings showing both an increase and a decrease. Fiber swelling:  Hair fiber diameter dimensions can change and be measured when exposed to water. Microscopic test – It is performed with a microscope that allows you to visually detect the hair cuticle and know if it is damaged or not. Under the microscope you can see: Low porosity – The hair cuticles will appear flat and closed. Medium hair porosity – The hair cuticles are slightly open. High porosity – The hair cuticles are lifted and opened. LOW POROSITY HAIR It has tightly bound cuticle layers that lie flat, making it healthy and shiny. Because the cuticles are tightly bound, once moisture is inside, it is difficult for moisture to escape. The characteristics It is very shiny because the cuticle lies flat creating a reflection for the light. It takes some time for hair to be fully saturated with products, especially butter and oils. It is resistant to chemicals and hair dyes. It rejects oils and butter that often weigh down non-porous hair. Hair takes longer to dry. How to Care for Low Porosity Hair Low porosity hair should rely on a routine that uses lightweight, water-based products and less protein. We have formulated the collection Light and Shine to cater to low porosity hair. It contains the Leave-in which is a water-based product that will moisturize the hair. The natural mask will moisturize your low porosity hair and the Curl Defining Jelly which is a lightweight styler that will define curls without weighing hair down or causing buildup. HAIR POROSITY AVERAGE The hair cuticles are neither too closed nor too open. The hair can absorb moisture and retain moisture for a period of time. The characteristics Medium maintenance is required. Hair is shiny but not as much as low porosity hair. It is possible to achieve normal porosity hair with the use of a proper regimen. Hair feels smooth when you run your fingers through a section of hair. The hair is easy to style and will hold the style for a long time. Hair can take on color and warmth. Medium porosity hair is healthy, so medium maintenance is required. This doesn't mean you should neglect your hair, as medium porosity hair can change if damaged. The collection Hair Growth Elixir Contains a mask and leave-in that will help nourish and hydrate hair to promote the growth of healthy, thick hair. HIGH POROSITY HAIR High porosity hair means raised, more spaced-out cuticles. Hair cuticles have gaps and holes, which make it very easy for hair to absorb products, but also very easy for products to leak out. High hair porosity can be caused by genetics or damage. The integrity of the hair cuticle can be damaged and disrupt the inner layers of the hair strand when exposed to mechanical damage (rough hair, friction, high heat, tight hairstyles), chemical damage (relaxers, bleaching), or environmental damage (chlorinated water, UV rays, sea water). The characteristics Running your fingers through a strand of hair can feel lumpy. Hair is dull and doesn't shine as much. Hair tends to be dry. Hair tends to break easily. Water and products are absorbed quickly upon application. It is difficult for hair to be soft and malleable. How to Care for High Porosity Hair You want hair products that aim to strengthen hair cuticles that have been damaged. The collection Real Protein Treatment contains a mask, a leave-in, a solid shampoo and a styling gel containing natural proteins. If the hair porosity is high, the hair is generally damaged, dull and dry, this collection is able to repair, strengthen, and rebuild the cuticle of your hair. This collection contains proteins that penetrate the hair cuticles, fill in the gaps and repair the hair structure.
