Collagen is an essential protein found in our body, accounting for about 30% of the total protein in our body. This protein is a key element in the health of our skin, bones, muscles, tendons and ligaments. But did you know that collagen also plays an important role in the health of our hair? Indeed, this protein contributes to the growth and strength of hair, as well as its elasticity. In this article, we will take a closer look at the effects of collagen on hair, presenting you with the benefits of this protein for your hair, the different ways to consume collagen, as well as practical advice on how to take care of your hair.

What is collagen?

Collagen is a fibrous protein found in our body, which is composed of several amino acids. This protein is essential for the structure and function of many parts of our body, including skin, bones, muscles, tendons and ligaments.

There are different types of collagen, but type I is the most abundant in our bodies, accounting for about 90% of the total collagen mass. This protein is particularly important for the health of the skin, bones and tendons.

Collagen is produced naturally by our bodies, but its production decreases with age. Other factors, such as sun exposure, pollution, stress and poor diet, can also affect collagen production.

In order to maintain a sufficient level of collagen in our body, it is possible to consume it in the form of food supplements. These supplements are often derived from animal sources, such as the skin and bones of cattle or fish. It is also possible to consume foods rich in collagen, such as jelly, marrow bones, chicken skin, or bone broth.

The benefits of collagen for the hair

Collagen is a key component of hair health, and can have several benefits for hair growth, strength and elasticity.

Promotes hair growth

Collagen plays an important role in the production of keratin, which is an essential protein for hair growth. Indeed, keratin is the main component of hair, and is responsible for its strength and elasticity. By consuming collagen, we can promote the production of keratin, which can stimulate hair growth.

Strengthens the hair

Collagen is also important for the structure of the hair, as it contributes to the formation of hair fibres. Consuming collagen can strengthen the hair structure, which can reduce breakage and split ends. Stronger hair can also appear fuller and shinier.

Improves hair elasticity

Collagen is a protein that gives elasticity to tissues. In hair, it can help maintain its flexibility and resistance to damage. More elastic hair will be less likely to break or become damaged during brushing, styling or other handling.

Promotes scalp health

Collagen can also have benefits for scalp health, helping to keep the skin well hydrated and elastic. A healthy scalp can promote hair growth and reduce problems with dandruff, itching or irritation.

How to consume collagen to benefit from its effects on hair?

There are several ways to consume collagen to benefit from its effects on hair, whether it is through collagen-rich foods, dietary supplements or hair products.

• Collagen-rich foods

Some foods are naturally rich in collagen, such as meats, fish and seafood, as well as certain vegetables such as peppers, cabbage and spinach. It is recommended that you choose quality, free-range or grass-fed foods to ensure optimal collagen intake.

• Food supplements

Collagen supplements are a popular option to benefit from its effects on hair. They usually come in powder, capsule or liquid form, and can be added to drinks or smoothies. It is important to choose a quality supplement, preferably hydrolysed collagen, which is more easily absorbed by the body.

• Hair products

Some hair products also contain collagen, such as shampoos, masks and lotions. They can help strengthen hair, reduce breakage and maintain elasticity. It is recommended to choose quality products, formulated with natural ingredients and adapted to your hair type.

It should also be noted that the effects of collagen on hair can take time to manifest themselves, and it is often recommended that you consume collagen for several months to see the effects.

The results of scientific studies on the effects of collagen on hair

Several scientific studies have been conducted to evaluate the effects of collagen on hair health, with encouraging results.

• Hair strengthening

A study published in the Journal of Cosmetic Dermatology found that collagen supplementation improved hair strength and elasticity, reducing hair breakage. Participants who took collagen supplements also reported improved hair texture and shine.

• Hair growth

Another study, published in the Journal of Investigative Dermatology, found that collagen plays an important role in hair growth. The researchers found that collagen stimulates the production of cells in the hair follicle, which promotes hair growth. This finding suggests that collagen may help combat hair loss and promote hair growth.

• Protection against environmental damage

Collagen can also help protect hair from environmental damage, such as pollution, UV rays and chemicals. A study published in the Journal of the American Academy of Dermatology found that collagen strengthens the skin barrier, preventing irritants from entering the hair and damaging it.

• Improved hair quality

Finally, a study published in the Journal of Drugs in Dermatology showed that collagen supplementation improved overall hair quality. The participants who took collagen supplements had a better overall hair quality.

Practical advice for taking care of your hair in addition to consuming collagen

Consuming collagen can help improve hair health, but it is important to complement this with a proper hair care routine to maximise results.

• Wash hair regularly

Regular hair washing is essential to maintain hair health. Hair should be washed according to its type and texture, but in general, it is recommended to wash at least twice a week. The use of a mild, sulphate-free shampoo is also recommended to avoid drying out the hair.

• Moisturising the hair

Moisturising is important for healthy hair. Use a moisturising conditioner to deeply nourish the hair and prevent split ends. It is also recommended to use a moisturising hair mask once a week for deep hydration.

• Avoid hot styling tools

Hot styling tools, such as straighteners and curling irons, can damage hair by drying it out and breaking it. Avoid frequent use or use them sparingly. Use a heat protector to minimise damage from hot styling tools.

• Protecting hair from the sun

The sun can damage hair by drying it out and lightening it. To protect hair from UV rays, wear a hat or use a hair spray with a UV filter.

• Avoid harsh chemicals

Chemicals such as hair dyes and perms can damage hair. Avoid their frequent use or use hair products without harsh chemicals.

• Eat a healthy diet

A balanced, nutrient-rich diet is important

Conclusion

In conclusion, collagen is an important structural protein found in the human body that helps maintain the health of tissues, including hair. Consumption of collagen can have beneficial effects on hair health, improving hair texture, shine and strength. It is important to consume collagen on a regular basis to benefit from its effects.

However, it is also important to note that collagen consumption alone cannot solve all hair problems. A proper hair care routine, such as regular hair washing, moisturising, protection from hot styling tools and sun damage, as well as avoiding harsh chemicals and eating a healthy diet, is also necessary to maintain hair health.

Finally, although the results of scientific studies on the effects of collagen on hair are encouraging, it is important to continue to conduct research to better understand the mechanisms of action of collagen and its effectiveness on hair health.

In sum, collagen consumption can be an important part of an overall hair care routine to maintain hair health, but it should not be considered a quick fix for all hair problems.
