OUR HEALTHY OUTSIDE STARTS FROM THE INSIDE

Thinning hair, brittle strands, and lacklustre locks can be frustrating—especially when you're doing everything "right" with your hair care routine. Many health-conscious individuals are turning to collagen supplements as a natural solution for stronger, healthier hair growth. But with different types of collagen available, which one actually works for hair health?

This comprehensive guide explores the science behind collagen and hair growth, helping you make an informed decision about which collagen type might benefit your hair health goals. We'll examine the different collagen types, their specific roles in hair health, and how to choose the right supplement for your needs.

Understanding different types of collagen

Collagen is the most abundant protein in your body, making up approximately 30% of your total protein content. This structural protein provides strength and structure to various tissues, including your hair, skin, nails, and bones.

Scientists have identified 28 different types of collagen, but five main types are most relevant to human health:

Type I collagen makes up about 90% of your body's collagen and is found in skin, hair, nails, bones, and connective tissues.

Type II collagen primarily supports cartilage and joint health.

Type III collagen works alongside Type I collagen in skin, blood vessels, and organs.

Type IV collagen forms basement membranes in various tissues.

Type V collagen supports cell surfaces and hair strands.

For hair growth specifically, Types I and III collagen are the most significant, though Type V also plays a supporting role.

Type I collagen and hair health

Type I collagen is the powerhouse for hair health. This collagen type provides the primary structural foundation for your hair follicles and hair shaft. Research shows that Type I collagen contains amino acids that your body uses to build keratin—the protein that makes up your hair.

The amino acid profile of Type I collagen includes proline, glycine, and hydroxyproline, which are essential building blocks for healthy hair growth. These amino acids support:

• Hair follicle strength: Stronger follicles can support healthier hair growth cycles
• Hair shaft integrity: Reduces breakage and improves hair texture
• Scalp health: Supports the dermal layer where hair follicles are anchored

Type I collagen also supports the dermal papilla, a small structure at the base of hair follicles that plays a crucial role in hair growth regulation. When these structures receive adequate collagen support, they can better maintain healthy hair growth cycles.

Type III collagen and scalp support

Type III collagen works synergistically with Type I collagen, particularly in supporting skin and scalp health. Your scalp's dermal layer contains both Type I and Type III collagen, which work together to maintain elasticity and strength.

This collagen type specifically contributes to:

• Scalp elasticity: Maintains flexibility and prevents tightness that could restrict hair follicles
• Blood vessel integrity: Supports proper circulation to hair follicles
• Wound healing: Helps repair any scalp damage that might affect hair growth

A healthy scalp environment is essential for optimal hair growth, making Type III collagen an important supporting player in your hair health routine.

The role of collagen supplements

As we age, natural collagen production decreases by approximately 1% per year after age 25. This decline can contribute to hair thinning, increased breakage, and slower hair growth. Collagen supplements aim to replenish these declining levels.

Hydrolysed collagen peptides are the most bioavailable form of collagen supplements. These smaller peptides are easier for your body to absorb and utilise compared to whole collagen proteins.

Clinical studies suggest that collagen supplementation may:

• Increase hair thickness and strength
• Reduce hair breakage
• Support faster hair growth
• Improve overall hair quality

Most collagen supplements contain a combination of Type I and Type III collagen, which provides comprehensive support for hair health. Look for supplements that specify their collagen sources and types on the label.

Food sources of collagen

Whilst supplements offer convenience, you can also support collagen production through nutrient-rich foods. Your body produces collagen naturally when provided with the right building blocks.

Collagen-rich foods include:

• Bone broth from grass-fed animals
• Fish with skin and bones
• Chicken skin and cartilage
• Egg whites
• Shellfish

Collagen-supporting nutrients:

• Vitamin C (citrus fruits, berries, bell peppers): Essential for collagen synthesis
• Zinc (pumpkin seeds, chickpeas, cashews): Supports collagen production
• Copper (dark leafy greens, nuts, seeds): Helps form collagen cross-links
• Protein (legumes, quinoa, hemp seeds): Provides amino acid building blocks

For those following vegan or vegetarian diets, focusing on collagen-supporting nutrients becomes particularly important since plant foods don't contain collagen directly.

How to choose the right collagen supplement

Selecting an effective collagen supplement requires attention to several key factors:

Source and type: Look for supplements containing Types I and III collagen from sustainably sourced marine or grass-fed bovine sources. Marine collagen typically has smaller peptides and higher bioavailability.

Third-party testing: Choose products that undergo independent testing for purity and potency. This ensures you're getting what the label promises without harmful contaminants.

Additional nutrients: Some supplements include vitamin C, biotin, or hyaluronic acid to support collagen synthesis and hair health.

Dosage: Most studies use 2.5-10 grams of collagen peptides daily. Start with the lower end and adjust based on your response.

Certifications: For those with specific dietary needs, look for non-GMO, gluten-free, or sustainably sourced certifications.

Potential risks and side effects

Collagen supplements are generally well-tolerated, but some individuals may experience mild side effects:

• Digestive discomfort (rare)
• Allergic reactions (particularly with marine-sourced collagen if you have shellfish allergies)
• Interaction with certain medications

Always consult with a healthcare provider before starting any new supplement, especially if you have existing health conditions or take medications. Pregnant or breastfeeding women should seek medical advice before using collagen supplements.

Lifestyle tips to boost collagen production

Supplements work best when combined with lifestyle practices that support natural collagen production:

Protect from UV damage: Sun exposure breaks down existing collagen. Use protective hairstyles and scalp sunscreen when spending time outdoors.

Manage stress levels: Chronic stress increases cortisol, which can interfere with collagen synthesis. Practice stress-reduction techniques like meditation or gentle exercise.

Stay hydrated: Proper hydration supports collagen formation and maintains scalp health.

Get quality sleep: Your body repairs and produces collagen during deep sleep phases.

Avoid smoking and excessive alcohol: Both habits accelerate collagen breakdown and impair hair growth.

Making an informed choice about collagen for hair growth

The science suggests that Type I and Type III collagen can support hair health when used as part of a comprehensive wellness approach. These collagen types provide the structural support your hair follicles need whilst maintaining scalp health.

Remember that hair growth is a slow process—it typically takes 3-6 months to see noticeable improvements with consistent collagen supplementation. Combine supplements with a balanced diet rich in collagen-supporting nutrients, protect your hair from damage, and maintain realistic expectations about results.

For the best outcomes, choose high-quality, sustainably sourced collagen supplements that align with your dietary preferences and lifestyle. Your hair—and overall health—will benefit from this natural, science-backed approach to hair wellness.

Every day, your skin works as your first line of defense, protecting you from external threats and maintaining your overall well-being. But did you know that much of this superhero-like ability is thanks to the trillions of microbes living on its surface? Your skin microbiome comprises bacteria, fungi, and viruses that create a dynamic, balanced ecosystem essential to your skin's health.

Curious about the microbiome’s role in your daily wellness? Here’s what you need to know and how you can nurture it naturally.

What is the Skin Microbiome?

Your microbiome is made up of microscopic organisms, called microorganisms, that live on and within the layers of your skin. These microorganisms, including bacteria, fungi, and viruses, work together in harmony to regulate various skin functions. Key players include:

• Bacteria like Staphylococcus and Corynebacterium
• Fungi, such as Malassezia
• Viruses, including bacteriophages

This delicate balance supports a healthy barrier that protects you from harmful pathogens, locks in moisture, and prevents skin conditions.

Why is a Balanced Skin Microbiome Important?

A healthy microbiome has far-reaching effects on overall skin health:

• Protects Against Pathogens

Beneficial microbes crowd out harmful bacteria, reducing the risk of infections.

• Supports Skin Barrier Function

It prevents water loss, shields against external irritants, and keeps skin hydrated.

Aqua or water-based skin products often contain chemical preservatives like parabens that can kill microbes indiscriminately, including the good guys.

• Antimicrobial Overload

Excessive use of sanitizers, antibiotics, and antibacterial products disrupts the balance.

• Petroleum-Based Formulas

These create an occlusive layer on the skin, suffocating beneficial microbes.

• Perfumes/Alcohol-Based Products

Chemical deodorants and fragranced items are harsh on the microbiome.

How to Support a Healthy Skin Microbiome

Here are practical steps you can take to nurture your microbiome and maintain balanced, healthy skin:

• Gentle Cleansing

Use mild, pH-balanced cleansers free of harsh ingredients like sodium lauryl sulfates or synthetic fragrances.

• Choose Microbiome-Friendly Moisturizers

Opt for natural solutions like ZERO BS, which mimics your skin's sebum and has moderate antibacterial and antifungal properties. It nourishes the skin while working like a probiotic for your microbiome.

• Limit Harsh Antimicrobials

Minimize the use of antibiotics, sanitizers, and antimicrobial products unless prescribed.

• Mind Product Ingredients

Avoid water-based products with chemical preservatives, emulsifiers, or petroleum derivatives.

Takeaway

Your microbiome is a diverse, intricate ecosystem that’s essential to your skin’s resilience and overall health. By adopting microbiome-friendly habits and choosing natural products, you can protect and enhance this delicate balance for radiant, well-nourished skin. There have been many medical studies on the effects of chemicals on the delicate skin microbiome, here is one.
