Why Collagen Is Essential for Healthy, Shiny Hair


Most of us know that collagen is good for our skin, but collagen provides a lot more anti-aging benefits – such as helping to improve hair growth, reducing hair loss, and keeping hair strong and shiny! We all lose collagen as we age, which can lead to premature aging and impact our bones, joints, and even our hair. Luckily, supplementing with collagen can help strengthen our hair and give us a healthy full body of hair. To learn about how to use collagen for hair, and how collagen can help your hair shine and grow, read on!


First of all, know that collagen affects much more than just your hair.

We love collagen, and we’re always eager to explain why. The why can actually be found just by learning about what collagen is. Collagen is a protein, the most abundant protein in the body. Already you can tell how important collagen must be. Collagen serves structural roles for parts of the body such as bones, tendons, joints, and stomach lining. It can also be found in external parts of the body, including our eyelashes, nails, teeth, and, as you may have guessed, hair! Collagen consists of a rather long chain of amino acids that is practically holding us together, connecting and building our connective tissue as well as our skin and bones. Unfortunately, the ability of the human body to produce collagen decrease in our twenties, which is why we begin to show signs of aging over time.

A lot of the ways collagen affects hair has much to do with how it affects our skin, the body’s largest organ. Collagen makes up 70% of our skin, and it can be found in the dermis. The dermis is the middle layer within human skin. The dermis is also where you can find hair follicles, small organs that regulate our hair growth. Maintaining the integrity of the dermis is how collagen helps your hair follicles – and therefore your hair (1)!


Collagen benefits for hair: Examining collagen’s contribution to hair

Let’s talk more about collagen’s role when it comes to helping your hair. In order for hair to thrive, the hair follicles and its sebaceous glands (glands internally attached to the top of each follicle that helps keep hair and skin moisturized) need to exist in a well supported dermal layer. The reduction of collagen in our bodies over time may be the way we tend to lose hair as we age. There is a relationship between hair thickness, hair moisture, and the total number of hair follicles with the amount of collagen in your body.


Collagen for Hair: What are the hair health benefits of collagen?

So you want to know how exactly collagen can benefit you in a way in which you can see and feel the results. Supplementing with collagen can provide the following benefits to your hair:

  • Collagen can improve hair growth, volume and length
  • Collagen may help to reduce hair loss
  • Collagen can help keeps your hair shiny

All the following hair health benefits you are about to read revolve around one simple trait: collagen is great for your hair!


Collagen improves hair volume and length, and reduces hair loss.

What most people dread as they age is the fact that they’re gradually losing more and more hair each year. Hair growth and hair regeneration can be supported by collagen thanks to its antioxidant properties. Researchers in Japan in 2016 found that when collagen levels near the stem cells of hair follicles are decreased, more hair is lost (2). The mice from the study also showed  a trend in which mice continuing to produce collagen experienced less hair loss. Proline, an important amino acid found in Type I and Type III collagen, helps prevent cell damage from free radicals. Free radicals, though naturally produced in the body, can lead to hair loss by damaging the hair follicles. Because collagen can help both reduce the damage from free radicals in addition to supporting your hair follicles, supplementing with collagen can benefit your hair (3). By upholding the quality of your hair follicles, your hair will continue to regenerate, grow, and increase in volume (collagen can widen the diameter of your hair strands). Your hair will be less likely to fall out given the strengthening it will get from collagen. Now you know that you can use collagen for hair growth, so get ready to maintain that full head of hair!


Collagen helps your hair shine.

Nobody likes when their hair is dry, brittle, and lacks that shine. Well, collagen is here to help! Remember that the sebaceous glands we mentioned contribute to the moisture levels of our skin and hair. They do this by secreting sebum, an oily sort of matter that lubricates the hair strands. The sebum is then deposited onto the skin and found on the hair. That coat is what makes hair shine so glamorously. Excessive sebum production can lead to infection and hair loss, but low sebum production can lead to dull and unprotected hair. Collagen can help this entire function by supporting the dermis and therefore the function of all tissue and glands within the layer (4). Great conditioner isn’t the only product that can give your hair that healthy shine!

The big takeaway here is that collagen helps your hair all around; it helps keep your hair on your head, and it helps keep your hair on your head healthy!
