Keratin's Impact on Hair Fortification and Healing
In the world of hair care, one substance stands out for its crucial role in maintaining healthy, strong, and resilient locks - keratin. This protein, found in abundance in our hair, is the backbone of each strand, making up almost 95% of its structure [1].
The hair root, nestled deep within the skin, is surrounded by the hair follicle, which produces the keratin that forms our hair [2]. But what gives keratin its unique properties that make it so essential for hair health?
The answer lies in the essential amino acids found within keratin. These amino acids, particularly sulfur-containing ones like cysteine and methionine, play a pivotal role in the formation and maintenance of keratin [3].
Cysteine, abundant in keratin, contains sulfur atoms that form disulfide bridges between protein chains. These bonds stabilize the hair's helical structure, contributing to its mechanical strength and elasticity [1][2]. Methionine, another sulfur-rich amino acid, is a building block for keratin synthesis and the structural integrity of hair proteins [2].
Together, these sulfur amino acids protect hair fibers, reduce porosity, and help maintain the smooth alignment of cuticle scales, which influences hair shine and minimizes breakage [1][2]. Other amino acids like proline, glycine, and hydroxyproline also contribute to keratin formation and hair structure, though cysteine and methionine are particularly vital due to their sulfur content [4].
Maintaining adequate levels and production of these keratin amino acids is vital for healthy hair. Damage to keratin due to hair processing techniques like thermal styling, bleaching, and coloring can cause hair breakage, hair loss, reduction in hair flexibility, and general damage to the strands [1].
Fortunately, there are products like Keranutri, a potent keratin product from the Careactives line of Provital, designed to help combat these issues. Keranutri contains amino acids derived from carob and soy, which stimulate keratin production and capillary repair [5]. This means it can help reduce hair permeability, improve capillary texture, and form a protective layer around the hair cuticle, resulting in healthy and hydrated hair [5].
Keranutri can be easily incorporated into your daily hair care routine. It can be mixed with your daily shampoo or conditioner, used as a hair serum, or added to hair treatments like bleaching and coloring to minimize damage [6]. By focusing on specific areas, anyone can achieve healthy and strong hair with regular use of a keratin treatment like Keranutri.
So, the next time you're looking for a way to improve your hair health, remember the power of keratin. By nurturing this essential protein and its constituent amino acids, you can help your hair stay strong, shiny, and resilient against the various stressors it faces daily.

- Science has unveiled the importance of sulfur-containing amino acids, such as cysteine and methionine, in the field of health-and-wellness, particularly for skin-care and hair health, as they play a key role in the formation and maintenance of keratin, a protein crucial for the structure of hair.
- Fitness-and-exercise routines that involve proper nutrition, including a healthy diet rich in these essential amino acids, can indirectly contribute to the wellbeing of one's hair, as these nutrients are vital for keratin synthesis and the structural integrity of hair proteins.
- Adequate nutrition, including the consumption of foods rich in keratin-building amino acids, can also positively impact overall health by ensuring the maintenance of strong and resilient hair, which is an integral part of one's physical appearance, much like how fitness-and-exercise routines contribute to a healthy body.
