If you’re looking for ways to speed up the process of your hair growing, this article about collagen for hair growth is perfect for you. If you’ve never taken a collagen supplement before, then you’re probably wondering what collagen is and why it’s relevant to the growth of your hair. Let me explain.

Collagen is a highly abundant protein in the body that is extremely beneficial for things like our skin, joints and hair. Composed of 18 different amino acids (the main three being glycine, praline and hydroxyproline), collagen is an essential part of cell renewal, bone strength and the strength of our tendons, joints (see our recommended collagen powders for joint health), nails, eyes, etc. We are able to produce collagen ourselves, but this process slows down as we hit the age of 30. It will continue to decrease from that point on. This is what leads to wrinkles, fine lines and thinning hair as we age.

One way to deal with a decreased production of collagen is to utilize a supplement each day. High quality collagen sources can help turn back the hands of time while also helping your hair grow. It’s also important that your body is getting enough vitamin C in order to properly produce collagen, so you may see these supplements fortified with that nutrient as well.

How Does Collagen Help with Hair Growth?

collagen powder hair growth benefits

There are a few different ways that collagen can help with hair growth. To start with, the antioxidants in collagen help our body fight back against free radicals caused by pollution, poor air quality, stress, diet, smoking and alcohol. Free radicals can be very damaging to hair follicles, which can slow down the growth of your hair and make it look thin. The amino acids in collagen can also support the production of keratin, which is the protein that is responsible for forming our actual strands of hair. If your supplement of choice contains marine collagen, this provides your body with additional praline, which is also essential for the relationship between keratin and hair formation.

In order for your hair to grow faster, you need to pay attention to the health of your scalp. Our hair follicles are situated on the dermis layer of our skin. This layer is largely made up of collagen. So, as we get older, our decreased collagen production will decrease the efficiency of our dermis layer to grow and maintain healthy hair.

What Is the Best Type of Collagen That Will Improve Hair Growth?

There are 28 different types of collagens, with type I and III being the most important when it comes to hair growth. Type I collagen is largely sourced from marine collagen, which is beneficial to our bones, skin, blood vessel walls, cartilage, and other tissues. This is also the form of collagen that is prevalent in the body.

What to Look for in a Collagen Powder for Hair Growth

When shopping for a collagen powder / supplement that will help you with your hair growth journey, there are some specific things to keep in mind.

Type I Collagen Included in the Supplement

I touched on this briefly earlier in this article, but I would like to explain this concept further. Type I collagen is the main collagen that has the ability to fight against all of the different free radicals that can impact your scalp. Instead of experiencing hair loss and hair thinning, your hair will look healthier, thicker and grow faster. By increasing the antioxidant presence around your hair follicles, you won’t have to worry about a slower regeneration process. When you’re trying to choose a collagen supplement that will provide you with the most benefits in regard to your hair, make sure that type I is included in the formulation.

Reputable Brand

You’re not going to get the results that you’re looking for if you don’t purchase a collagen supplement from a reputable brand. By reputable I mean a company that has loyal customers that have experienced positive results from regular use of a product. It’s important that you can trust that a company has created their products using scientific information, high-quality ingredients and has put a great deal of research into potential benefits.

Safety – Third Party Tested

In order to determine that a product is safe, third-party testing should be utilized. This means that a company will outsource the testing of their products so you can ensure that they’re producing accurate and truthful results. Third-party testing can confirm the purity and potency of a product while sometimes testing for banned substances.

Free of Additives

The best collagen supplements for hair growth are free of artificial additives and ingredients. You want only pure collagen and other pure nutrients that are going to get the job done without causing harm to the body.

Transparent Ingredients

A brand that deserves your business will be very truthful about what is in their products. Transparency is key so you know what you’re putting into your body. Look for a full ingredient list but see if there is additional information on the company’s website that explains where ingredients are sourced and why.

Who Should Add a Collagen Supplement to Their Diet?

adding collagen to diet

While this article largely focused on using collagen supplements to promote faster hair growth, you can also reap the benefits of increased collagen production in regard to other areas of the body. If you experience persistent pain or discomfort in your joints, want to decrease inflammation in the body or feel like you’re not recovering from your workouts quickly enough, it might be time to start adding collagen to your routine each day. Collagen is very well tolerated by most people, and it’s something that can be included with many of your other supplements that you’re already taking.

Collagen vs. Biotin

Collagen and biotin are both used for beauty-related benefits and other health functions, but there are some key differences that I want to point out. Biotin is very rich in vitamin B7 and contains collagen. It has an important role in fatty acid metabolism and cell growth. While it can also help with hair growth and skin health, biotin also has biological benefits like regulating blood sugar and digestive functions.

Collagen functions as a main structural protein that can be found in things like our nails, bones, muscles, skin, tendons, and connective tissues. It essentially works hard to keeps the body functioning as a strong, whole unit.

Side Effects That You Need to Know About

collagen side effects safety

Collagen is well tolerated by many people, but there are side effects that you should take note of before trying a supplement of this type. For example, it can result in high levels of calcium in the blood when taken in excess. A hypersensitivity response can occur as well, which would cause the immune system to overreact to a potential allergen or trigger. Lastly, some people experience a dry mouth or a bad taste in their mouth when they are taking collagen on a regular basis. These are just some side effects to watch out for, and you may want to speak with your doctor if you’re concerned with any of them prior to starting a supplement for the first time.

The Bottom Line

If you have decided to utilize a collagen supplement for the purpose of hair growth, you can talk with a trusted doctor regarding how you should take these supplements. Your exact dose may depend on what you’re hoping to achieve and your current state of health.

Make sure that you’re choosing a collagen supplement that is formulated with high quality ingredients. Stay away from artificial ingredients and additives that simply lower the quality of a product. You may want to ensure that hyaluronic acid and vitamin C have been added as well, to maximize the benefits of your collagen therapy for hair growth and regeneration.

Tips for Success from the RD

Aside from using collagen to get your hair to grow faster, here are some of my tips for success that can help you achieve luscious and healthy locks.

Wash Less Frequently

If you are used to washing your hair every single day, you could be doing more harm than good. When you’re washing frequently, this process can strip away natural oils that protect your hair. Even the best conditioner can’t replace those natural oils. If you have an oily scalp, try washing every other day to start out with. You can wash less frequently if you wish.

Take a Multivitamin

It’s beneficial to take a supplement that contains specific ingredients for hair growth, but you might want to try a daily multivitamin supplement as well. If you have nutritional gaps in your diet, these missing vitamins and minerals might be slowing down the growth of your hair.

Work More Healthy Fats into Your Diet

Increasing your levels of plant-based omega’s can decrease any inflammation that is present on your scalp. This can promote faster hair growth.
