Unlocking Luscious Locks: The Role of Collagen for Hair Growth

 cbd for hair growth

Inside the hair follicle is a dynamic world where various elements come together to shape the health and appearance of your hair. One crucial component that plays a significant role in this intricate process is collagen.

Within the hair follicle, collagen, a structural protein, provides the necessary framework that supports the strength and elasticity of your hair strands. As we age, the production of collagen in the body tends to decline, affecting not only the skin but also the health of our hair, making it thin and brittle. 

Incorporating collagen into your hair care routine may be a game-changer. Supplements and products enriched with collagen can work from the inside out, replenishing the levels of this vital protein in your body to promote hair strength and thickness. 

So, What Exactly is Collagen?

Collagen is the most abundant protein found in the body, and it’s responsible for fortifying the skin, bones, ligaments, joints, tendons and hair. Its main functions include supporting cell growth, dead cell turnover, organ protection, skin elasticity and blood clotting.

Of the five primary types of collagen known to researchers, types 1, 3 and 5 collagen likely play the largest role in the health of your hair. Moreover, studies have also found that deficiencies in subtypes 6 and 17 may result in hair loss and impair healthy hair growth, respectively. 

That said, oral collagen supplements, like fish-derived collagen, may enhance hair growth and prevent hair loss. 

Let’s explore why.

The lifecycle of a hair follicle comprises three unique stages:

  • Anagen (growth) – During this phase, the hair follicle is actively growing, and new hair is formed. This stage can last for several years, and the length of the hair is determined by the duration of the anagen phase.
  • Catagen (regression) – In this transitional phase, the hair follicle begins to shrink and detach from the blood supply. This stage is relatively short, lasting only a few weeks. The hair stops growing, and the outer root sheath undergoes structural changes.
  • Telogen (rest) – The telogen phase is a resting period for the hair follicle. During this time, the detached hair remains in place while a new hair begins to form beneath it. This phase can last for a few months, and around 10-15% of hairs on the scalp are typically in the telogen stage at any given time.

Studies suggest that collagen may influence the development of the hair follicle during the anagen phase. Specifically, it can increase hair thickness and hair follicles and improve hair dryness and hair dullness. Collagen may also have antioxidant and wound-healing properties to support overall scalp health.

Collagen For Hair Growth

While significantly more research is needed on the topic of collagen for hair growth, studies have discovered notable potential benefits through several specific mechanisms.

#1 Amino Acids

Peptides make up collagen. When you zoom in, you find amino acids, the building blocks of proteins. Of the known amino acids, eleven are nonessential, meaning the body makes these naturally. In other words, you don’t need to obtain them through your diet.

Collagen contains three of these nonessential amino acids:

  • Proline – Proline is one of the main components of keratin, which your hair is primarily made from. Additionally, proline contributes to the overall integrity of collagen, ensuring its ability to provide support and resilience to various tissues, including skin, tendons and, of course, hair. 
  • Glycine – The smallest amino acid, glycine, is abundant in collagen and contributes to its flexibility. Specifically, it plays a vital role in collagen's ability to withstand stretching and bending, making it an essential component for the elasticity and suppleness of your hair.
  • Hydroxyproline – Hydroxyproline plays a key role in the stability of collagen by forming hydrogen bonds within the protein structure. These bonds contribute to the overall strength and resilience of collagen fibers, ensuring the structural integrity of your hair follicles.

#2 Antioxidant Properties

Antioxidants can protect your body from free radicals that can damage cells, including those responsible for maintaining the health and appearance of your hair. 

Free radicals are unstable molecules generated by exposure to factors such as pollution, UV radiation and stress. They wreak havoc by stealing electrons from other molecules in your body, leading to oxidative stress and potential damage to your hair follicles.

Collagen, specifically from fish, may have antioxidant properties that help to protect the integrity of your hair. In fact, these antioxidant properties may be even more beneficial than the plant-based antioxidants found in tea. 

Alongside collagen's antioxidant benefits, understanding how to increase my protein intake through diet can further enhance hair strength and vitality, as protein is a key component of hair structure.

#3 Anti-Aging Properties

As you age, collagen production decreases, impacting your hair in two ways: thinning and graying.

Collagen supplementation might prevent the former due to collagen’s role in scalp health. The protein makes up 70 percent of the skin where hair roots live, helping to maintain its elasticity and strength. Collagen also helps to promote new skin cell turnover to prevent hair thinning. 

To the latter point, we return to antioxidants. Collagen’s potential antioxidant properties may help to prevent cell damage of melanin, a compound that gives your hair its natural pigment. Accordingly, taking a collagen supplement may slow the rate at which the hair turns gray. 

How to Incorporate Collagen Into Your Hair Care Routine

Collagen supplements come in various forms, including powders, capsules and liquid formulations. These options provide flexibility in how individuals can incorporate collagen into their daily hair care routines. 

#1 Collagen Supplements

One popular and convenient method of collagen supplementation is adding collagen powder to beverages such as coffee, tea or smoothies. You can also add unflavored collagen peptides to your favorite foods, such as:

  • Soups and chilis
  • Baked goods 
  • Oatmeal
  • Dips and sauces
  • Yogurt and pudding

Opt for an oral collagen supplement that contains type 1, 3, and 5 collagen, as these types are known to play a significant role in promoting hair health. Fish-derived collagen supplements, in particular, have shown potential benefits for hair growth and the prevention of hair loss.

Follow the recommended dosage instructions on the supplement packaging, and keep in mind that consistency is key to seeing the potential long-term benefits of collagen for your hair.

#2 Collagen-Infused Hair Products

You can also look for hair care products that specifically mention collagen as one of their key ingredients. Collagen-infused shampoos and conditioners can provide direct nourishment to your hair strands during the washing process, promoting strength and vitality.

Also, consider incorporating collagen-rich hair masks or treatments into your weekly routine. These intensive treatments can deeply hydrate and strengthen your hair, leaving it looking and feeling healthier.

#3 DIYCollagen Hair Treatment

Create your own collagen-rich hair treatment using natural ingredients. 

For example, mix collagen powder with ingredients like yogurt, honey or coconut oil to create a nourishing mask. Apply this mixture to your hair, leave it on for a specified time and then rinse for an at-home collagen boost.

#4 Collagen-Rich Diet

Support healthy hair growth from the inside out by incorporating collagen-boosting foods into your diet. To enhance your body’s collagen production, add foods like:

  • Bone broth
  • Fish
  • Chicken
  • Leafy greens
  • Egg whites
  • Citrus
  • Berries and tropical fruits
  • Garlic
  • Beans
  • Cashews
  • Tomatoes
  • Bell peppers

For those aiming to enhance their collagen intake while managing a budget, we have a comprehensive guide on how to eat healthy on a budget.

Also, reduce the amount of sugar and refined carbs you eat every day. A surplus can damage collagen levels in your body. As you embrace the benefits of collagen for your hair, don't overlook the significance of meal timing in your overall wellness routine as well, which can impact the effectiveness of supplements and the health of your hair.

#5 Adequate Hydration

Hydration is essential for overall hair health. Plus, collagen supplements work more effectively when the body is adequately hydrated. Ensure you’re drinking enough water throughout the day to maximize the benefits of collagen for your hair.

Experts recommend that men drink 13 cups daily, while women should drink at least nine cups a day. 

#6 Protective Habits and Accessories

In conjunction with your collagen-rich hair care routine, also take the time to protect your hair to preserve your progress.

Limit the use of heated styling tools that can cause damage to your hair. Heat can weaken the structural integrity of hair strands, and collagen can aid in maintaining that strength.

Also, consider using hair products or accessories that provide UV protection to shield your hair from the harmful effects of the sun.
