 Keratin vs Protein Treatment 

The main difference between Keratin and Protein Treatment is that Keratin treatment is primarily composed of Keratin, a component the hair is composed of and penetrates the hair easily. On the other hand, Protein treatment is a mixture of multiple proteins extracted from various plant and animal sources for hair needs. 

Keratin vs Protein Treatment

Keratin treatment is a popular hair treatment popularized as Keratin is a crucial component in hair. It is ideal for all hair types- straight, wavy, and curly.

The treatment straightens the hair and maintains the softness and endurance. It nourishes the hair and fulfills the lack of protein in the hair. 

Protein Treatment is a treatment providing all the essential proteins for hair to maintain its length and restore vitality. It is a mixture of amino acids that adds smoothness to hair and avoids brittleness, roughness, and fizziness.

What is Keratin Treatment?

Keratin is a major part of the hair. It is because keratin is a pre-existing protein found in skin, nails, and hair. Keratin is present in large amounts in straight or wavy hair, whereas the levels are low in curly hair. 

Genetic factors and chemical processes to straighten the hair are causes for keratin deficiency. Thus, Keratin treatments are available in the market. They are effective in nourishing the hair and protecting it from damage. 

Keratin is extracted from the skin and nails of cattle, and plants. It is a hair treatment, not a hair straightening product. Thus, it cannot alter or enhance the texture of the hair.

It means that it cannot turn the coarse hair texture into finer hair. It protects hair from further damage and compensates for the lack of keratin in hair.

It is a restorative treatment that strengthens the shaft and adds resilience. Keratin treatment is added to the hair and sealed with the help of a flat iron. It penetrates the solution into the hair. The process may take around 90 minutes or more. 

Keratin treatment is criticized because formaldehyde, a component responsible for carcinogen production hampers the hair. You can go for Zero Formalin products. 

What is Protein Treatment?

Protein treatment is an advanced idea of Keratin treatment. Hair is made of protein, specifically Keratin. Protein treatments help the hair to retain moisture, get nourished. It is because Keratin protein in the air unravels and breaks down when susceptible to regular damage over time. 

Protein treatments are not simply Keratin. They are an amalgamation of a variety of amino acids and other types of proteins that work together to eliminate hair damage by boosting the protein matrix, supporting and rebuilding the hair bonds. 

The treatment has proteins like silk amino acids and hydrolyzed wheat protein attaching to the hair follicle and tightening the cuticles.

It avoids dust particles, sun rays, and other harmful foreign objects penetrating the cuticle layer. It protects from contamination and impairment. 

It is essential to enhance the hair elasticity to stretch more and bounce back. It eliminates split ends and breakage. It elongates the hair by preventing weakness and brittleness in the follicles. It is essential for timely deep cleansing and nourishing based on different strengthening needs. 

There are many protein treatments: 

  • Caviar treatment: is rich in vitamins and fatty acids. 
  • Silk Protein: Revive dry hair.
  • Soy Protein: Improve hair strength and restore moisture.

Main Differences Between Keratin Treatment and Protein Treatment 

  1. Keratin treatment is perfect for people who straighten their hair every day. Protein treatments are great for people looking to reconstruct hair bonds.

  3. Keratin treatment is preferred every 4-5 months to ensure minimal hair damage and optimum results. Protein treatments can be done at home once or twice a month based on hair needs. 
  4. Keratin treatments are more prone to containing Formalin, which is harmful to hair. Whereas, Protein treatments are less prone to having Formalin in their formula. 
  5. Keratin treatment is not ideal for curly and wavy hair due to its effects. Protein treatments are perfect for curly and wavy hair for providing softness and encouraging hair to clump better.
