Does Collagen Help With Hair Growth?

A question we often get asked at The Beauty Chef is, "does collagen help with hair growth?" While we know it’s excellent for supporting bouncy skin, this article takes a closer look at the potential benefits of collagen for hair growth.

From hair loss to maintaining your mane’s hydration, we explore the most common hair concerns and whether or not the skin-plumping protein has any effect. After all, a good hair day is always worth looking into.

Here’s everything you need to know about the relationship between collagen and hair growth.

What Is the Relationship Between Collagen and Healthy Hair?

Collagen and hair growth share a scientific connection. Collagen, a predominant protein in the body, can contribute significantly to hair strength and vitality. Here's how it works: Collagen increases the activity of fibroblasts (specifically dermal papilla cells) in the skin, which serve as messengers to cells located at the base of hair follicles. These cells are responsible for generating new hair. Put simply, collagen can act as a catalyst to promote the growth of healthy hair.  

5 Benefits of Taking Collagen to Support Hair Growth 

From improving hair elasticity to reducing hair loss, here are five ways collagen can help with hair growth and contribute to stronger and healthier hair. 

Collagen Contains Amino Acids to Support Hair Growth 

Collagen contains three key amino acids: proline, glycine and hydroxyproline. These amino acids provide a strong foundation for the protein structure of hair, promoting healthy hair growth. Proline and glycine enhance keratin production (the protein that makes up hair strands), meanwhile hydroxyproline supports collagen's structural integrity in the scalp, ensuring a conducive environment for hair follicles to thrive. By supplying these essential building blocks, collagen can play a vital role in nurturing full-bodied hair.  

Collagen Can Reduce Hair Loss & Promote Healthy Roots 

Collagen has the potential to both reduce hair loss and promote healthy roots. It supports the dermis layer (where hair follicles are anchored), helping to maintain hair stability. Its regenerative properties help to preserve a resilient scalp and prevent hair loss, highlighting the natural benefits of collagen for hair loss and scalp health. 

Collagen Can Improve Hair Elasticity 

Another possible benefit of taking collagen is improved hair elasticity and flexibility. By strengthening the hair shaft and enhancing its structural integrity, collagen reduces the likelihood of breakage and split ends. This can result in more manageable hair that is less susceptible to damage. By reinforcing hair fibres, collagen fosters better hair quality and resilience, promoting overall hair health.  

Collagen Can Improve Hair Hydration 

Lastly, collagen can contribute to maintaining well-hydrated hair by enhancing moisture retention. It can achieve this by bolstering the hair's structural integrity and preventing moisture loss. A lack of collagen can lead to dry, brittle hair that is more prone to damage. When collagen levels are optimal, the hair is able to retain its moisture, resulting in a healthier, glossier appearance. By supporting hair hydration, collagen contributes to general hair health, ensuring that it remains shiny and strong. 

The Bottom Line on Collagen Benefits 

So, can collagen help with hair growth? While it's not a miracle fix, collagen shows promise in supporting healthy hair. It’s possible that it could help in aiding hair growth, reducing hair loss, improving elasticity and boosting hair hydration. However, genetics and overall health play an important role, too.
