What Is Better For Thinning Hair Biotin Or Collagen?

Biotin supplements and collagen supplements have become more popular these days as they are believed to help promote hair growth and increase its health.

So what is better for thinning hair biotin or collagen? In this article, I will include the difference between biotin and collagen, how they help improve hair health, which one to try, risk factors, and more…

Let’s dive deep into it…

What Is The Difference Between Biotin And Collagen?


Biotin, also known as vitamin B7 or vitamin H, is found in many foods like salmon and eggs. This vitamin helps our bodies convert proteins, carbohydrates, and fats in food into energy

It also metabolizes glucose, fatty acids, and amino acids that are responsible for producing protein in the body.

Biotin is an essential nutrient that our bodies don’t produce and it’s water-soluble, which means your body will not be able to store it.

So you need to get it daily from other sources like foods that contain biotin or supplements.

Usually, it’s uncommon to have biotin deficiency especially if you consume balanced healthy meals. But if you have, it leads to brittle nails, hair loss, hair breakage, skin infections, and flaky red rashes.

Collagen is a protein in the human body that is made of non-essential amino acids; glycine, proline, and hydroxyproline. Our bodies produce collagen naturally, but as we age, it breaks down and becomes harder for the body to produce more.

Collagen is found in bones, muscles, teeth, corneas, blood vessels, skin, tendons, and joints.

It’s responsible for keeping the skin elastic and firm, boosting joint health, and leaving blood vessels, bones, and corneas lubricated and moist.

Also, sufficient collagen levels in the body help build lean muscles, grow strong nails and thicker hair, boost immune response, and heal wounds.

A study showed that collagen loss can make the skin thinner, increase wrinkles and fine lines, leave the skin dehydrated, and slow wound healing.

Unlike biotin, collagen is not water-soluble, which means your body can absorb and store it.

To boost collagen production, you can consume foods that contain collagen like bone broth, or take supplements to fight aging signs and boost your overall health, including hair health.

How Does Biotin Help With Thinning Hair?

Several studies showed that nutritional supplements could help treat hair loss, reduce bald spots, and hair thinning.

They have antioxidant and anti-inflammatory properties that can boost hair growth, reduce breakage, keep the scalp healthy, and condition and moisturize the strands.

A study found that biotin supplements help reduce hair loss in people with biotin deficiency.

Another study of 156 women showed that taking biotin supplements whether having or not having biotin deficiency could lead to a significant decline in hair loss.

But this study is not enough as it shows weak evidence for this claim due to lack of the participants.

So, we still need more studies to support the evidence that suggested biotin can reverse hair loss and boost hair thickness.

How Does Collagen Help With Thinning Hair?

Collagen helps build keratin, which is a type of protein that forms hair, nails, and skin.

Plus, 70% of the dermis, the middle layer of the skin that holds hair roots, is made up of collagen.

A study found that collagen may reduce age-related hair thinning or loss caused due to lack of strength and elasticity of the dermis.

Another study showed that taking collagen supplements for 12 weeks can help boost skin elasticity, increase hydration and density, and prevent roughness in women over 35.

And this will for sure reflect on hair health. But we still need more studies to support the evidence.

Collagen can also fight free radical damage that weakens hair follicles and cause hair loss.

Free radicals appear in the body due to stress and other environmental factors that could lead to stress-induced hair loss.

What Is Better For Thinning Hair Biotin Or Collagen?

So biotin vs collagen for hair growth, which one is better? Biotin breaks down nutrients in the body to help renew and grow cells while collagen boosts hair follicle growth and keeps the scalp’s dermis strong.

So, both of them work differently but still, help with hair growth. That’s why some people take them together to maximize the benefits.

Plus, there’s no evidence that taking both of them together is unsafe. But before taking anything, make sure to talk first to your doctor.

So what if there’s a product that contains biotin and collagen together? It would give you exactly what you need, right?
