Is collagen good for hair?

Common name: collagen

INCI: hydrolysed collagen

Origin: animal (bovine, fish), biotechnological

Obtainment method: hydrolysed collagen is extracted mainly from the skin, bones or scales of animals (usually bovine or fish), or from plant sources that stimulate collagen production. The hydrolysis process breaks down the protein into shorter peptides, making them easier to absorb by the skin or body.

Biochemical composition: collagen is a protein composed of three coiled chains forming a structure called tropocollagen. It consists mainly of amino acids such as glycine and proline and carbohydrates.

Collagen is one of the most abundant proteins in the human body, accounting for around a third of all proteins in the body. It forms the basis of our connective tissues such as bones, skin, tendons and cartilage. It is even found in the corneas of our eyes and in our internal organs, as well as in our blood vessels. This macromolecule is present in several forms in our bodies, and there are in fact several types of collagen:

• Type I collagen: the main interstitial collagen, found in the dermis, tendons, bones and vascular walls.

• Type II collagen: found in cartilage and the vitreous body of the eye

• Type III collagen: found in the dermis and vascular walls

• Type IV collagen: present in the basal lamina

• Type V collagen: present in muscles, placenta, etc.

In total, there are more than 16 different types of collagen in the body, but the most abundant are types 1, 2 and 3.

Collagen is a polysaccharide, a natural carbohydrate in the glycosaminoglycan family. It is also a protein (i.e. composed of a succession of amino acids). Its fundamental unit, called tropocollagen, is 280 nm long and 1.5 nm in diameter. It is a glycoprotein formed by the coiling of three left-handed α-helices carrying carbohydrates (glucose, galactose). The amino acids are glycine, proline,hydroxylysine and 4-hydroxyproline. The carbohydrates are attached to hydroxylysine, and it is the coiling of the three α chains that forms the tropocollagen molecule. Collagen plays a crucial role in the regeneration and structure of skin tissue, and also plays a part in skin elasticity.

Collagen is essential to your skin's healthy appearance, giving it volume, elasticity, firmness and resistance. Collagen proteins also play an essential role in maintaining healthy, young-looking hair. Lastly, collagen plays a part in intestinal comfort, joint health and even helps our brains function properly!

From the age of 25, our bodies begin to synthesise collagen less effectively, and then our collagen stocks fall drastically after the age of 50. This drop in our collagen stocks leads to skin ageing, loss of firmness, loss of hair density, lack of muscle tone and joint pain.

• Sheathes and strengthens hair by forming a film, sheathing the cuticle, reinforcing and protecting it while having a noticeable thickening effect.

• Makes hair soft and shiny.

• Encourages keratinocyte production and promotes hair growth and elasticity when taken orally.

In cosmetics, collagen is very often used in hair care products, in hair salons and in hair protective products. A few years ago, hair straightening with collagen was the talk of the town. Today, there are natural, plant-based solutions for making your own collagen treatments and improving your hair's appearance. Aroma-Zone's Plant Collagen cosmetic active ingredient can be easily incorporated into your volumising shampoo recipes, fine hair recipes or simply to enrich a hair mask base.

You can also use a course of marine collagen while incorporating our Plant Collagen active ingredient into your daily hair care routine for its overall effects.

Does marine collagen make hair grow?

Although there is limited documentation on this, a 2019 study highlighted the effect of collagen on keratinous tissue. Although this study focused mainly on nails, it suggests that collagen promotes the growth of keratinous tissue. Nails and hair are both mainly made up of keratin, so we can assume that collagen could have similar beneficial effects on hair, improving its structure, strength and potentially promoting growth.

Marine collagen - 250 G - Food supplement

Made from hydrolysed marine collagen peptides, it is an ideal food supplement taken as a course to combat the signs of skin ageing. This type 1 collagen, manufactured in France, is clinically proven to help firm the skin. Lastly, marine collagen is also an essential supplement for athletes.

This food supplement is not a substitute for a varied and balanced diet and a healthy lifestyle. Do not exceed the recommended daily dose. For adults only. Not recommended for people with kidney failure without medical advice. Keep out of reach of young children. Pregnant or breastfeeding women are advised to seek the advice of a healthcare professional before taking any supplements.

To preserve the effectiveness of your product, store it in a cool, dry place away from light.

Take your collagen on an empty stomach to maximise its absorption. This means it is absorbed more quickly and effectively by the body. On an empty stomach, collagen does not compete with other nutrients, allowing it to pass more easily into the bloodstream.
