Introduction
If you have noticed more hair in your shower drain lately or your ponytail feels a little thinner than it used to, you are likely looking for solutions that actually work. Hair health often starts from the inside, and collagen has become one of the most discussed supplements for restoring shine and volume. At BUBS Naturals, we focus on providing clean, science-backed nutrition to help you stay active and feel your best, whether you are hitting the trails or just trying to maintain your daily wellness.
This guide will break down the specific types of collagen that support hair health and how they function within your body. We will look at the science behind hair follicles, the differences between various collagen sources, and how to choose the right supplement for your goals. Understanding what type of collagen is good for hair growth is the first step toward a more resilient, healthier head of hair.
Quick Answer: Type I collagen is the most effective for hair growth because it provides the specific amino acids needed to build keratin. It is primarily found in marine collagen and bovine collagen, which help support the scalp environment and strengthen hair follicles.
Understanding Collagen and Hair Structure
To understand how collagen helps your hair, you first need to understand what your hair is actually made of. Hair is primarily composed of a protein called keratin. While your body produces keratin naturally, it requires specific building blocks to do so efficiently. These building blocks are amino acids, many of which are found in high concentrations within collagen.
Collagen is the most abundant protein in the human body. It acts as the "glue" that holds everything together, providing structure to your skin, bones, tendons, and ligaments. Your hair follicles, which are located in the dermal layer of your skin, rely on collagen to maintain their structure and elasticity. As we age, our natural collagen production begins to decline, which can lead to thinner skin and weaker hair follicles.
The Role of the Dermis
The dermis is the middle layer of your skin, and it is roughly 70% collagen. This is where the root of every hair strand lives. When collagen levels are high, the dermis remains strong and elastic, providing a healthy environment for hair to grow. If the dermis weakens due to collagen loss, the hair follicles may not receive the support they need, which can lead to thinning or slower growth rates.
The Keratin Connection
Your body uses several amino acids to produce keratin. One of the most important is proline. Proline is also a main component of collagen. By consuming collagen, you provide your body with a concentrated source of proline and other amino acids like glycine and hydroxyproline. This gives your body the raw materials it needs to create the keratin that makes up each strand of hair.
Collagen Peptides
What Type of Collagen Is Good for Hair Growth?
There are at least 28 different types of collagen in the human body, but the vast majority of our collagen consists of Types I, II, and III. When it comes to hair, not all types are created equal.
Type I Collagen
Type I is the most abundant form of collagen in the body, accounting for about 90% of your total supply. It is found in your skin, hair, nails, bones, and tendons. Because it is a primary structural component of the skin and hair, Type I is widely considered the best type for supporting hair growth and thickness. It provides the density and strength required to maintain a healthy scalp and resilient hair strands.
Type III Collagen
Type III collagen is often found alongside Type I. It supports the structure of muscles, organs, and arteries. In the skin, Type III helps with elasticity and hydration. While Type I does the heavy lifting for hair, Type III plays a supporting role by ensuring the skin on your scalp remains supple and healthy.
Type II Collagen
Type II collagen is primarily found in cartilage. It is excellent for joint health and mobility, but it does not play a significant role in hair growth. If your primary goal is improving your hair, a supplement focused on Type II collagen—often sourced from chicken—will not be as effective as one containing Type I and III collagen.
Key Takeaway: For hair growth and thickness, focus on supplements that contain Type I and Type III collagen. These provide the specific amino acids and structural support necessary for the scalp and hair follicles.
Comparing Collagen Sources: Marine vs. Bovine
When you shop for a supplement, you will mostly see collagen sourced from either cows (bovine) or fish (marine). Both can be beneficial, but they have different characteristics that might make one a better fit for your routine.
Marine Collagen
Marine collagen is sourced from the scales and skin of fish. It is almost exclusively Type I collagen. Because the peptides in marine collagen have a smaller molecular weight, many people find it easier to absorb. This is often called "bioavailability." If your sole focus is hair, skin, and nails, marine collagen is a highly targeted choice.
Bovine Collagen
Bovine collagen comes from cow hides and is a rich source of both Type I and Type III collagen. Our Collagen Peptides at BUBS Naturals are sourced from grass-fed, pasture-raised bovine to ensure a clean and effective product. Bovine collagen is a versatile option because it supports not only your hair and skin but also your gut health and muscle recovery. Many people prefer bovine collagen because it is typically tasteless and mixes easily into hot coffee or post-workout shakes.
| Feature | Marine Collagen | Bovine Collagen |
|---|---|---|
| Primary Types | Type I | Type I & III |
| Main Benefits | Hair, Skin, Nails | Hair, Skin, Gut, Recovery |
| Bioavailability | Very High | High |
| Sourcing | Wild-caught or farmed fish | Grass-fed, pasture-raised cows |
| Flavor Profile | Neutral (if high quality) | Very Neutral |

Join The ClubHow Collagen Supports the Hair Growth Cycle
Hair growth happens in cycles. Every follicle goes through three distinct phases: anagen (growth), catagen (transition), and telogen (resting).
Extending the Anagen Phase
The anagen phase is the active growth period, which can last several years. Some research suggests that collagen may help support the health of the hair follicle during this phase. By providing a steady supply of amino acids and protecting the follicle from oxidative stress, collagen can help the hair stay in the growth phase longer, leading to more length and volume.
Fighting Free Radical Damage
Free radicals are unstable molecules that can damage cells, including those in your hair follicles. They are caused by environmental factors like pollution, UV rays, and smoking. Collagen acts as an antioxidant, helping to neutralize these free radicals. By protecting the hair follicles from damage, collagen may help prevent premature thinning and even slow down the graying process that occurs when pigment-producing cells are compromised.
Improving Scalp Circulation
A healthy scalp requires good blood flow to deliver nutrients to the hair follicles. Collagen helps maintain the strength and elasticity of your blood vessels. This supports better circulation throughout the body, including the scalp. When your follicles have a steady supply of oxygen and nutrients, they are better equipped to produce strong, healthy hair.
Bottom line: Collagen supports hair by providing building blocks for keratin, acting as an antioxidant to protect follicles, and maintaining the structural integrity of the scalp.
The Importance of Bioavailability and Peptides
You cannot simply eat a piece of steak and expect the collagen to go straight to your hair. In its natural state, collagen molecules are too large for the body to absorb efficiently. This is why high-quality supplements use "hydrolyzed" collagen, also known as collagen peptides.
Hydrolysis is a process that breaks down the long chains of collagen protein into smaller pieces. These peptides are much easier for your digestive system to process. Once absorbed, they enter the bloodstream and are distributed to the tissues that need them most, such as the dermis and hair follicles.
We ensure our products are hydrolyzed to the highest standard. This means they dissolve instantly in liquid and are ready for your body to use. When a supplement is easy to absorb, you are more likely to see the benefits in your hair’s appearance and strength. If you want a deeper breakdown, our article on what collagen peptides are and how they can benefit you is a helpful next step.
Factors That Deplete Your Natural Collagen
Even if you take the right type of collagen, certain lifestyle habits can undo your progress. Collagen is a resilient protein, but it is sensitive to environmental and dietary stressors.
- High Sugar Consumption: Sugar attaches to proteins in your blood to form molecules called AGEs (advanced glycation end products). These molecules can damage nearby collagen, making it dry and brittle.
- UV Exposure: Too much sun breaks down collagen fibers in the skin, including the scalp. This can weaken the foundation where your hair grows.
- Smoking: Nicotine constricts blood vessels and limits the delivery of oxygen and nutrients to your skin and hair. It also directly damages collagen and elastin.
- Aging: This is the one factor we cannot change. Starting in your 20s, you lose about 1% of your collagen production every year. By age 40, your levels have significantly declined.
By supplementing with Type I and III collagen, you are essentially helping to backfill the gap created by these factors.
How to Use Collagen for Best Results
Consistency is the most important part of any supplement routine. You likely will not see a difference in your hair after a single scoop. Hair grows slowly—usually about half an inch per month—so it takes time for the new, collagen-supported hair to emerge.
Daily Dosage
Most studies on collagen and hair health use a daily dose of 5 to 10 grams, though some people choose to take up to 20 grams. A single scoop of our Collagen Peptides provides a significant dose of Type I and III collagen. It is best to take it every day to maintain a steady supply of amino acids in your system.
Timing and Mixing
There is no "wrong" time to take collagen. You can add it to your morning coffee, mix it into a smoothie, or stir it into a glass of water after a workout. Because our formula is unflavored and dissolves easily, it fits into whatever routine you already have. Some people like to combine it with our MCT Oil Powder for a boost of mental clarity alongside their hair and skin support.
Pairing with Vitamin C
Vitamin C is a critical cofactor for collagen synthesis. This means your body cannot effectively produce or use collagen without it. If you are taking a collagen supplement, make sure you are also getting enough Vitamin C through your diet or a supplement. Our Boosts Collection includes simple add-ons designed to support your routine.
Myth: Applying collagen topically through shampoos or serums can regrow hair. Fact: Collagen molecules are too large to be absorbed through the skin or the hair shaft. While topical collagen can help hydrate the hair and make it look shinier temporarily, you must ingest collagen peptides for them to reach the hair follicles and support actual growth.
Beyond Hair: Additional Benefits of Types I and III
While you may be starting your collagen journey for hair growth, the benefits of Type I and III collagen extend much further. These are the same proteins that support your entire body's structure.
Skin Elasticity and Hydration
Since Type I collagen is the primary protein in your skin, supplementing can lead to improved hydration and elasticity. Many people report that their skin feels firmer and looks more radiant after consistent use. It may also help reduce the appearance of fine lines by supporting the dermal layer.
Nail Strength
If your nails are brittle or prone to peeling, Type I collagen can help. Much like hair, nails are made of keratin. Strengthening the "root" of the nail with amino acids can lead to faster growth and less breakage.
Joint and Bone Support
While Type II is the specialist for cartilage, Types I and III still play a role in overall joint health. Type I is a major component of your bones and tendons. For active individuals, this means better support for the connective tissues that keep you moving.
Why Quality Matters
The supplement industry is not always transparent. Some products are filled with additives, sugar, or low-quality protein sources. When choosing a collagen for hair growth, you want a product that is as clean as possible.
We believe in doing things the right way. Our collagen is third-party tested and NSF for Sport certified. This means what is on the label is exactly what is in the tub—no fillers, no BS. This level of testing is why our products are trusted by professional athletes, members of the military, and everyday fitness enthusiasts alike.
When you use a clean product, you are giving your body exactly what it needs without the extra junk that can cause inflammation or digestive upset. Simple ingredients lead to better results.
Choosing the Right Collagen for You
If your primary goal is specifically hair growth and thickness, look for a supplement that features Type I collagen prominently. For the most well-rounded approach, a blend of Type I and III is ideal.
If you prefer a fish-based diet or have a high sensitivity to bovine products, marine collagen is your best bet. However, for most people, a grass-fed bovine collagen like ours provides a more versatile range of benefits, supporting hair, skin, gut, and joints all in one scoop. If you want to compare options, which type of collagen to take is a useful guide.
Remember to listen to your body. Everyone's biochemistry is slightly different. Some people notice changes in their nails first, while others see a difference in their hair texture within a few months. Patience and consistency are your best tools.

FAQ
Which collagen type is best for thinning hair?
Type I collagen is the most effective for thinning hair because it is the primary structural protein in the skin and hair follicles. It provides the amino acids, particularly proline, needed to produce keratin, which strengthens the hair shaft.
Can I take collagen and biotin together for hair growth?
Yes, collagen and biotin can be taken together as they serve different but complementary roles. Collagen provides the structural building blocks for the hair and scalp, while biotin helps the body metabolize those proteins and supports the health of the hair follicles.
How long does it take to see results in my hair from collagen?
Since hair grows slowly, most people begin to notice visible changes in hair thickness, shine, or growth after 3 to 6 months of consistent daily use. You may notice improvements in nail strength and skin hydration sooner, often within the first 4 to 8 weeks.
Is marine or bovine collagen better for hair?
Both are excellent sources of Type I collagen, which is the most important type for hair. Marine collagen has a slightly smaller particle size for easier absorption, while bovine collagen provides both Type I and Type III, making it a more versatile option for overall health.
