Key Takeaways

  • Collagen helps hair health by providing essential amino acids needed for keratin production. Studies show it can boost hair growth factors like IGF-1 and VEGF.
  • Marine collagen, from fish like Mozambique tilapia, is highly effective for hair growth. It absorbs well and has shown positive results in lab studies.
  • Bovine collagen also supports healthy hair by strengthening follicles. While promising, more research is needed to confirm its full effects on pattern hair loss.
  • Collagen supplements may promote thicker and healthier hair but come with risks such as stomach issues and allergic reactions. Always consult a doctor before starting any supplement.

What is Collagen?

Collagen is a key protein in our bodies. It keeps hair, skin, and other tissues strong and stretchy. This protein supports the structure of our hair follicles.

Fish-derived collagen is among the best sources. Collagen from Mozambique tilapia is cost-effective and absorbs well into the body. Using collagen peptides can prolong human hair follicle growth in lab settings.

These peptides also help maintain healthy hair follicles by keeping stem cells quiet or inactive when needed.

The Claim: Collagen and Hair Growth

Can collagen really promote hair growth, or is it all just hype? Let’s look at the science behind this popular claim…

Does collagen promote hair growth?

Yes, collagen promotes hair growth. Fish collagen peptides from Mozambique tilapia stimulate the human dermal papilla cells (hDPCs). These cells are crucial for healthy hair growth.

The collagen helps to increase key factors like IGF-1 and VEGF that support hair regrowth.

Oral doses of 500 mg/kg and 1000 mg/kg show significant effects in mice. These results indicate how well collagen can work for humans too.

 

Collagen is a building block for strong and healthy hair

 

The biological rationale behind collagen and hair health

Collagen is the most abundant protein in your body. It’s found in muscles, skin, and bones. But how does collagen help hair? Collagen plays a role in maintaining healthy hair by providing essential amino acids needed for keratin production—the key protein that makes up our hair.

Enhanced hair regrowth has been seen with collagen peptides. Studies on mice show that fish-derived collagen activates the Wnt/β-catenin signaling pathway. This promotes the anagen phase, leading to better hair follicle growth and thickness.

The decrease of TGF-β1 helps prevent hair loss too.

  • Marine collagen increased the expression of key hair growth factors. Factors like IGF-1, VEGF, and Ki67 showed higher levels with marine collagen.
  • The treatment reduced the inhibitory factor TGF-β1. This means fewer blockers for hair growth.
  • More active hair follicles were observed in the study groups using marine collagen. The ratio of anagen (growth phase) to telogen (rest phase) improved.
  • CP treatments upregulated Wnt/β-catenin signaling pathways. These pathways are crucial for developing new hair follicles on your scalp.

These findings suggest marine collagen may encourage healthier and more abundant hair… Now, let’s explore how supplements might also play a role in promoting hair health!

Research on collagen’s role in reducing hair aging

Research shows that collagen can play a role in reducing hair aging. Treatments with collagen peptides (CP) have shown promising results.

  • CP treatment increases human dermal papilla cell (hDPC) growth and hair regrowth. These cells are key to forming new hair.
  • Histological checks revealed a higher anagen/telogen (A/T) ratio in CP-treated groups, meaning more active hair follicle growth stages.
  • CP treatment boosts hair growth factors like IGF-1, VEGF, and Ki67. These factors help with healthy and thicker hair growth.
  • TGF-β1, an inhibitory factor, is reduced with CP treatment. Lower levels of TGF-β1 mean less hair thinning and loss.
  • Collagen supplements may prevent hair loss by strengthening the hair shaft and improving overall hair health.
