Collagen vs Biotin: Which One Is Better for Hair Growth?

May 16, 2023

When it comes to hair growth, there are many supplements on the market that claim to promote healthy and strong locks. Two popular options are collagen vs biotin. But which one is better?

What is Collagen?

Collagen is a protein found naturally in our skin, hair, and nails. It provides structure and strength to these tissues, making them more resilient. As we age, our collagen production decreases, leading to thinning hair and wrinkles. Collagen supplements aim to replenish the body’s stores and improve hair health.

What is Biotin?

Biotin, on the other hand, is a B-vitamin that plays a crucial role in cell growth and metabolism. It’s often marketed as a hair supplement because it supports the production of keratin, a protein that makes up hair strands.

Collagen vs Biotin for Hair Growth

While both collagen and biotin have potential benefits for hair growth, research suggests that collagen may be the better option.

A 2018 study found that women who took collagen supplements for 90 days experienced significant improvements in hair thickness, elasticity, and density. In contrast, a 2017 review of biotin studies found little evidence to support its use for hair growth.

Why Collagen May Be More Effective for hair growth

One reason why collagen may be more effective is that it addresses the underlying cause of hair thinning: a lack of structural support. When collagen levels decline, hair follicles become weaker and more prone to damage. By supplementing with collagen, we can provide the necessary building blocks for stronger, healthier hair.

Biotin, on the other hand, only supports the production of keratin, which is only one component of hair. While keratin is important for hair strength, it doesn’t address other factors that contribute to hair health, such as scalp health, hydration, and nutrient intake.

The Importance of a Healthy Lifestyle for hair growth

Ultimately, the best approach to promoting healthy hair is a balanced diet rich in nutrients like protein, iron, and vitamin D. Supplements like collagen and biotin may have some benefits, but they should be used in conjunction with a healthy lifestyle rather than as a substitute for one.

Choosing the Right Collagen Supplement

It’s also important to note that while collagen supplements have been shown to improve hair health, not all supplements are created equal.

Look for high-quality collagen supplements like ProPlenish, derived from sustainably sourced marine collagen, specifically Type I collagen, which is the most prevalent collagen in the body. Additionally, ProPlenish offers superior bioavailability, ensuring optimal absorption and effectiveness.

In summary, while both collagen and biotin have potential benefits for hair growth, collagen may be the better option due to its ability to address the underlying cause of hair thinning.

It is important to also emphasise that maintaining a healthy diet and lifestyle should always be the foundation of any effective hair care routine.
