Spend any time in the world of hair care, and you’ll likely come across the term ‘keratin’. This popular hair ingredient is often highlighted as a key feature of many hair care products - but do you know what it is and why it truly matters for hair strength and thickness?
If you’re looking to take great care of your hair, understanding keratin is one of the first steps in a proactive hair care routine. Here’s how keratin can help to support your hair’s health over time.
What is Keratin?
Keratin is a naturally occurring structural protein that functions like the foundational building block of our hair, skin, and nails. Each of our hair strands are made up largely of keratin fibres, bundled together to create strength and flexibility. These fibres form the internal structure of the hair shaft, with the outer layer acting as a protective shield.
When keratin levels are strong and healthy, they contribute to hair that’s smoother, stronger, shinier, and thicker in appearance. When they’re damaged, the opposite takes place, leaving hair that looks dull, fragile, and thin.
How Keratin Can Become Damaged
The routines of our everyday life can quickly take a toll on the keratin structures in our hair. Many experiences can contribute to breakdowns in keratin proteins:
- Heat styling
- Chemical colouring
- UV exposure (particularly in Australia!)
- Harsh shampoos
- Friction from brushing
Over time, these everyday occurrences can weaken the hair shaft, increasing the likelihood of split ends and hair breakage. For those who are already experiencing thinning hair or hair loss, hair breakage can accelerate these issues, with hair snapping before it has the chance to grow. This is where keratin products can make a major difference to your hair’s health.
Keratin’s Impact On Hair Thickness
While keratin doesn’t change how many hair follicles you have, it does have a direct influence on how thick and healthy each of these strands appears. When the hair’s keratin structure is strengthened and reinforced:
- Hair feels denser to the touch
- Breakage is reduced
- The cuticle lies flatter, creating more shine
- The overall hair volume is improved
Since stronger strands mean less breakage, each strand can maintain better length and fullness. For those with brittle hair or who experience high degrees of hair breakage, incorporating more products with keratin is one easy way to support a healthier hair growth environment.
Conclusion
You’d be forgiven for thinking keratin is a buzzword, but in reality, it’s the structural foundation that gives your hair necessary support for strength, flexibility, and visible thickness. By choosing products that protect and support your hair’s natural keratin, you’re fuelling hair that’s more resilient, less likely to break, and better able to maintain length and fullness over time.
