How Does Collagen Help in Hair Growth?

How Does Collagen Help in Hair Growth?

For centuries, thick, lustrous hair has won hearts of the people, inspiring countless traditional remedies and modern solutions. The latest buzzword in this quest? Collagen. But does this structural protein truly hold the key to getting thicker, healthier hair, especially in the hot, often sun-drenched climate of the UAE? Let's get into the science and explore how collagen might influence your hair's growth potential in this unique environment.

Hair Growth

What is Collagen?

Collagen is the most abundant protein in your body, forming the foundation for your skin, bones, muscles, and, yes, even your hair. As we age, collagen production naturally declines, leading to the visible signs of aging we all know. But could this decline also impact hair health, particularly in the harsh sun and dry air of the UAE.

The Follicle Factor

Hair doesn't just magically erupt from your scalp. Each strand originates from a complex unit called a hair follicle. These tiny pockets house stem cells that constantly divide and differentiate, eventually forming the keratin protein that makes up your hair shaft.

Here's where collagen comes in:

  1. Collagen is rich in specific amino acids, the building blocks of protein. These amino acids, particularly glycine, proline, and hydroxyproline, are crucial for keratin synthesis, making sure your hair grows strong and resilient.

  2. The dermis, the deeper layer of your scalp, is primarily composed of collagen. A healthy, resilient dermis provides a strong foundation for hair follicles, promoting optimal growth and anchoring them firmly in place.

  3. Studies suggest collagen peptides may improve blood circulation, including to the scalp. This enhanced blood flow delivers vital nutrients and oxygen to hair follicles, nourishing them and supporting their growth potential.

  4. As we age, free radicals wreak havoc on our cells, including those in our hair follicles. Collagen possesses antioxidant properties, potentially helping to combat these damaging molecules and protect hair from premature ageing and breakage.

The Evidence

While the science seems promising, the verdict on collagen's direct impact on hair growth remains somewhat inconclusive. Here's a glimpse into the current research:

Small-scale studies

  • A 2015 study published in the "Journal of Cosmetic Dermatology" showed an increase in hair thickness and reduced breakage in women with thinning hair after taking collagen peptides for 24 weeks.
  • A 2020 study in the "International Journal of Trichology" observed enhanced hair growth and reduced hair loss in individuals taking collagen peptides for 16 weeks.


Beyond Supplements

While collagen supplements have garnered much attention, remember, collagen is naturally present in several dietary sources readily available.

  • Dates: These iconic fruits are a natural source of collagen and offer additional benefits like vitamins and minerals.
  • Fish: Oily fish like salmon, tuna, and sardines are excellent sources of omega-3 fatty acids linked to healthier hair growth and reduced inflammation.
  • Eggs: Eggs are rich in biotin, essential for hair health, and protein, contributing to strong, resilient hair.


The Process

The exact process by which collagen could affect hair growth is still being actively researched, here's what we currently understand:

  1. Collagen Breakdown and Absorption
  • Collagen, whether from dietary sources or supplements, gets broken down by the body into its constituent amino acids in the digestive system.
  • These amino acids enter the bloodstream and become available for various bodily functions, including protein synthesis.
  1. Amino Acid Utilisation for Hair Growth
  • Hair follicles have specific requirements for certain amino acids, including those found in abundance in collagen (proline, glycine, and hydroxyproline).
  • These amino acids can be used by the hair follicle to synthesise keratin, the primary protein building block of hair.
  • Increased availability of these specific amino acids, potentially influenced by collagen intake, could contribute to stronger and healthier hair growth.
  1. Collagen's Impact on Scalp Environment
  • Healthy collagen fibres create a supportive network in the dermis, the layer of skin where hair follicles reside.
  • This network anchors the follicle and provides structural integrity, promoting optimal function and potential hair growth.
  • Collagen degradation due to ageing or other factors can weaken this network, potentially hindering hair growth.
  • Maintaining healthy collagen levels could create a more favorable environment for the hair follicle.
  1. Additional Potential Mechanisms
  • Collagen's antioxidant properties might neutralise free radicals that damage hair follicles, promoting a healthier growth environment.
  • Its potential anti-inflammatory properties could further benefit the hair follicle by reducing inflammation that can hinder growth.
  • Recent research suggests interactions between collagen and signaling pathways within the hair follicle, potentially influencing gene expression related to hair growth, but these mechanisms are still under investigation.

Important Caveats

The actual process of collagen influencing hair growth might vary depending on individual factors like absorption efficiency, underlying health conditions, and genetic predispositions.


Do You Need Collagen Supplements?

Collagen is the buzzword du jour in the world of beauty and wellness. From powders to pills, everyone seems to be touting its benefits of collagen for glowing skin, luscious locks, and stronger nails. But before you jump on the bandwagon, let's find out if you actually need collagen supplements.

The truth is, it's a complex question with no one-size-fits-all answer. Our bodies naturally produce collagen, but production slows down as we age, potentially contributing to wrinkles, thinner hair, and weaker nails. This is where collagen supplements come in, promising to replenish those dwindling stores and restore youthful vibrancy.
