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.
