Restoring and Enhancing Hair's Integrity with Keratin
In the world of hair care, maintaining a healthy and vibrant mane is paramount. Understanding the building blocks of hair, such as keratin and its essential amino acids, can help us make informed choices about the products we use.
Hair, a complex structure, consists of three main parts: the hair shaft, the hair follicle, and the hair root. The key amino acids in keratin, crucial for hair structure and repair, are cysteine, proline, and glycine.
Cysteine, containing sulfur, forms disulfide bonds that reinforce keratin's helical structure, giving hair its strength, elasticity, and resistance to external stress. Proline, a major component of keratin, contributes to the building of hair structure by affecting the shape and stability of the protein chains. Glycine supports the overall structure of keratin and collagen, which together influence hair strength and health.
Keratin, produced by hair follicle keratinocytes, makes up about 95% of hair. Its structure, particularly rich in sulfur-containing amino acids like cysteine, lends hair its durability and flexibility. However, damage from chemical, thermal, or mechanical stress can degrade these disulfide bonds, weakening hair structure and increasing porosity.
For repair, plant-based phytokeratin with a low molecular weight can penetrate the hair cuticle and help fill in gaps, reducing porosity and smoothing the surface to maintain shine, suppleness, and protection from moisture loss.
In addition to these amino acids, biotin (vitamin B7) is important as a coenzyme that supports the synthesis of amino acids and fatty acids, critical for keratin production and the resilience of hair structures.
Enter Keranutri, a comprehensive topical keratin product from Provital's Careactives line. Keranutri contains amino acids derived from carob and soy hydrolysates, particularly high in cystine and methionine amino acids. The free amino acids in Keranutri improve hair structure and resistance, reduce hair permeability, form a protective layer around the hair cuticle, and result in healthy and hydrated hair.
Arginine, an amino acid present in the hair, helps to improve hair growth and strength by producing nitric oxide, which improves blood circulation in the area. Proline, methionine, and lysine work together to form keratin and collagen in the hair, acting as essential building blocks and promoting hair growth and elasticity.
Keranutri can be used during hair treatments like bleaching and dyeing to minimize and prevent unnecessary hair damage or keratin loss. It can be mixed with daily shampoo or conditioner and applied to the scalp, or used as a hair serum and applied directly to the hair. Incorporating a keratin treatment like Keranutri protects hair structure by improving specific areas and allowing anyone to have healthy and strong hair.
Adding Keranutri directly to the bleach can achieve a beautiful hair color without severe damage. Cysteine, another structural amino acid, forms a protective shield around the hair, preventing its breakage and contributing to a smoother and shinier appearance.
In essence, maintaining the level and production of keratin is vital for healthy and good-looking hair. By understanding the role of cysteine, proline, glycine, biotin, arginine, and keranutri in hair health, we can make informed decisions about our hair care routines and enjoy the benefits of strong, healthy, and beautiful hair.
