80% of the weight of hair is due to the presence of protein (amino acid polymers), among which the main one is keratin, composed of 18 amino acids. The main amino acids that make up keratin are: cystine (17.5%), serine (11.7%) glutamic acid (11.1%), threonine (6.9%), glycine (6.5%) and lastly arginine (5.6%).
Biotin is a water-soluble vitamin that helps the body to metabolise fats, carbohydrates and protein. It also plays an important role in the health of your hair, skin and nails. Keratin is a basic protein that makes up your hair, skin and nails, and biotin may improve your body's keratin structure.
Essentially composed of keratin, hair also contains other elements and molecules that contribute to its appearance and behaviour. The overall chemical composition of hair is 45 % carbon, 28 % oxygen, 15 % nitrogen, 7 % hydrogen and 5 % sulphur. The hair shaft is essentially composed of keratin.
Human hair is made from the protein keratin. Each strand of hair grows from a root located in the base of the hair follicle, which is composed of keratin cells. The keratin that makes up the major part of the hair is formed by amino acids molecules sourced from the food we eat.
The follicle is the primary structure from which hair can grow.
In addition to water, the elements that compose the chemical composition of hair are: keratin, lipids, minerals and pigments. Keratin is a protein found in the cortex. Keratin is composed of 18 amino acids.
Yes, absolutely! Stress, excessive heat styling, age and even genetics can deplete your hair's thickness. Keeping your scalp and roots healthy is how you can promote the growth of thick hair.

Hair is mainly composed of keratin proteins and keratin-associated proteins (KRTAPs).
Keratin is the protein naturally found in hair, forming the building-blocks of its structure. Vegan keratin is a moisturising humectant that conditions and hydrates the scalp, while also holding anti-irritant benefits.
Hair color is determined by the amount of a pigment called melanin in hair. An abundance of one type of melanin, called eumelanin, gives people black or brown hair. An abundance of another pigment, called pheomelanin, gives people red hair.
The hair is a complex biological structure composed mainly of proteins, water, lipids, minerals and pigments. La keratin is the main protein making up hair. It represents approximately 95% hair composition. Keratin is a protein the fibrous structure that gives hair its strength, resilience and structure.
Keratin is the fibrous protein that accounts for 90% of every hair strand. It's also present in your skin and nails. Spot keratin in a product ingredient list and you can be confident it will boost your hair's strength, while healing and repairing its natural structure.
Look for these key ingredients: Minoxidil and finasteride are the gold standards for hair regrowth. Other beneficial ingredients include biotin, caffeine, copper peptides, and saw palmetto. Avoid irritants: Alcohol, sulfates, parabens, and fragrances can dry out and inflame the scalp, potentially worsening hair loss.
Hair conditioner is a cosmetic product used to improve the appearance and texture of hair. A moisturizing or conditioning agent, hair conditioners are made up of humectants and emollients as their two primary ingredients, along with oils, silicones, and cationic surfactants (or soaps and detergents).
“Insufficient protein in the diet may result in stalled hair growth, dullness and even hair loss.” To support hair health, she suggests eating protein-rich foods such as eggs, dairy products, pulses, whole grains, tofu, fish, meat and nuts.
Keratin is a protein that your body produces naturally, and it helps keep your hair, skin and nails healthy and strong. Your body produces keratin naturally, but keratin shampoos and conditioners that contain keratin hydrolysates may strengthen your hair and improve its appearance.
Asian hair is by far the thickest of all hair types – 80 - 120 µm in diameter. Because of its extra diameter, it is also the strongest, and most resistant to damage.
Type 1A: The rarest hair type, this one is very straight and fine with a “wispy” appearance. It's very difficult to get it to hold a curl. Type 1B: Though still straight, this type has a medium (rather than fine) texture and a little more volume.
Their higher price is due to ethical sources, the use of high-quality hair, careful craftsmanship, and the fact that they last a long time and can be styled in many different ways. They also look great in natural colors and can be customized in many ways.
