Benefits of collagen for your hair

Collagen works like „glue“ that holds the body together. When it comes to hair, collagen takes part in maintaining its structure and elasticity, so it is the main ingredient that makes hair shiny, strong and quite simply the way you would want it. With ageing, when our body's collagen levels generally fall, our hair changes both structure and density. A collagen drop can make hair drier, finer, more brittle and prone to falling out. These effects can be addressed precisely by supplementing collagen as part of an anti-ageing routine. Let us look at the specific ways in which collagen acts directly on hair.

Collagen has a scientifically confirmed effect on:

  1. Protecting hair follicles from free radicals: Collagen acts as an antioxidant that protects cells against damage from free radicals. Oxidative stress caused by free radicals can disrupt hair follicles and lead to weakening and breakage. A regular collagen intake can help protect hair follicles and thereby support healthier hair growth.
  2. Improving scalp circulation: Collagen supports the formation of blood vessels and improves blood circulation in the scalp. Good blood flow is key for healthy hair growth because hair follicles are supplied with oxygen and nutrients. Improved circulation can lead to stronger and thicker hair.
  3. Strengthening the hair shaft: Collagen contains a high proportion of amino acids such as glycine, proline and hydroxyproline, which are essential for producing keratin, the basic protein that makes up our hair. Regular collagen intake can supply the body with the building blocks it needs to form stronger hair shafts.

 

If you are considering collagen supplementation, you should know that not all forms of collagen are the same. Hydrolysed collagen (collagen peptides) is considered the most effective form, because it is already broken down into smaller particles that the body absorbs easily. You can take it in powder form (collalloc), which dissolves easily in water, or as a tincture (collalloc NANO 2.0). Collagen nutrition should also be paired with vitamin C, which is essential for collagen synthesis in the body. Without enough of that vitamin the body would not be able to use the collagen effectively. Our collalloc NANO 2.0 already contains vitamin C, so this intake is covered.

Collagen in shampoos and conditioners: Is it worth it?
Besides supplements, collagen often shows up in cosmetics, shampoos, conditioners or masks. Even though applying collagen directly to the hair can improve its appearance on a short-term basis, the real impact on hair structure and growth is close to zero. Collagen molecules are relatively large and may struggle to penetrate deeply into the hair shaft.

 

If you long for stronger, healthier and shinier hair, it is worth considering including collagen in your daily routine. But do not forget that the basis is always a balanced diet, a healthy lifestyle and proper hair care. Collagen can be the cherry on top that gives your hair the vitality it needs.
