What Ingredients Are in Yanagiya Prexceed Collagen Hair Serum?

Yanagiya Prexceed Collagen Moisturizing Hair Serum is a mix of three ingredients to hydrate and moisturize hair. It should be applied to dry or towel-dried hair and left in. The amount of the serum to use is dependent on length of the hair; always adjust after reading package instructions. Yanagiya Prexceed Collagen Moisturizing Hair Serum is only a mix of collagen, amino acid and keratin with no fillers, preservatives or fragrances.

Collagen

Collagen is a protein found in the body that helps out bone, muscles, skin and organs. Collagen can deteriorate in skin or hair through natural events like aging and man-made events like through unprotected sun damage. There can be animal-based collagen added to formulas and plant-based collagen, also known as pseudo-collagen, according to the online Cosmetics Cop.

Any added collagen in personal care products has not been shown to increase or improve the collagen levels in the skin or hair; however it is a good water-binding agent. Collagen added to hair or skin products is usually used for this purpose and is why it is in Yanagiya Prexceed Collagen Moisturizing Hair Serum.

Amino Acid

Amino acids are found in all body proteins and are one of the ingredients in Yanagiya Prexceed Collagen Moisturizing Hair Serum. Examples of amino acids are glycine, lysine, alanine, arginine and serine. They are added to personal care products for partial antioxidant properties and for water-binding agent properties. It is a natural moisturizing factor and the skin or hair shaft cannot tell the difference between a plant amino acid and an animal amino acid, according to the Cosmetics Cop website.

Some amino acids have wound healing abilities and can act in that nature in person care formulas. On hair it is going to pull water in and keep the shaft hydrated.

Keratin

Keratin is a large family of proteins and is found in two types; keratin I and keratin II. Keratin is what gives hair its structural makeup and comes from chemicals bonding, according to the Swiss Institute of Bioinformatics. Water, in any form like humidity, can break these bonds. It is why hair can turn frizzy in humid weather. Keratin bundles can be altered after the bonds are broken. Keratin added to hair products can alter the style of the hair, making it less likely to frizz for example.
