Collagen is one of the most important building blocks of hair, teeth, and nails. An insufficient level of this protein in the body, or disruptions in its synthesis process, can cause excessive hair loss, weaken hair, and contribute to a decline in overall hair health. A lower amount of collagen fibers can even lead to premature hair loss. These problems can be prevented by deciding to supplement with collagen.

Does collagen help hair? Which type of collagen should you choose to stimulate healthy hair growth and restore shine to strands: fish collagen or beef collagen? We give you some tips!

What affects hair condition?

Hair is considered an important element of beauty by many people. Since ancient times, humans have regarded hair as a symbol of physical attractiveness, and caring for hairstyles was a practice thousands of years ago. There is no doubt that beautiful, healthy hair has immense significance for people.

We don’t always have control over the appearance of our hair, as sometimes it simply doesn’t develop properly. Damage and developmental defects can affect both the structure of the hair and its quantity. The primary factors that cause hair damage include:

  • natural factors - primarily caused by external factors such as sunlight, wind, and low temperatures
  • chemical factors - caused by excessive hair treatments and the use of inappropriate hair care products
  • physical factors - resulting from the use of high temperatures (using hairdryers, curling irons, straighteners)
  • mechanical factors - caused by improper washing, combing, tying, teasing, and other mechanical damage

One of the most common problems with the scalp is excessive hair loss. This occurs when the hair growth cycle is disrupted, meaning the balance between hairs in the growth phase and the resting phase is disturbed. The reasons for excessive hair loss can vary widely. Some of the most common causes include genetic factors, chronic stress, hormonal imbalances, improper hair care, certain medications, and poor nutrition.

Increased hair loss can also be a result of a lack of structural protein in the body. As we age, collagen production decreases, and fibroblasts produce less of it. As a result, hair becomes thinner, rougher, and drier. It can also fall out excessively. The aging processes occurring in the scalp and hair can be counteracted by preventing collagen deficiency. For this reason, many people use collagen for hair growth, which is available in tablet, capsule, or powder form to be dissolved in water.

Best collagen

How does collagen help hair?

To avoid the negative effects of excessive hair loss, it’s worth reacting as soon as possible to thinning hair. In many cases, hair loss can be stopped by careful hair care and supplementation. To strengthen the hair structure and increase its resistance to mechanical damage, it is a good idea to consider adding collagen preparations to your daily diet.

Before we answer the question of which collagen for hair works best, let's briefly explain how this crucial structural protein, which is present in the human body, affects the condition of hair strands.

Collagen is an important component of the extracellular matrix in the body. It’s part of connective tissue, skin, hair, and hair follicles. Its main task is to provide strands with valuable amino acids needed to produce keratin (glycine, proline, and hydroxyproline). Additionally, collagen strengthens hair follicles and increases the level of moisture in the scalp, which is extremely important for the proper structure of growing hair. Furthermore, it prevents split ends, which improves the appearance of the hair and its overall condition.

Collagen for hair growth and hair loss

Maintaining a healthy and properly moisturized scalp is crucial for proper hair growth. Regular use of collagen for hair may help maintain an optimal environment within the hair follicles, which may result in reduced hair loss. As a result of collagen supplementation, hair may become better nourished, and the proper structure of hair follicles can translate into improved hair appearance.

Which collagen for hair to choose?

Collagen is an essential component of the daily diet that helps maintain healthy, shiny, and beautiful hair. Since the amount of this valuable protein in the body decreases with age, it is very important to supply it externally — through food or by using collagen-containing dietary supplements.

There are various types and forms of collagen preparations available on the market. When choosing the best collagen for hair, pay attention primarily to its composition, quality, and the source of the collagen protein. Remember that for beautiful, healthy hair, the most valuable types of collagen are I and III, which are the main structural proteins of hair and connective tissue. The most bioavailable form of collagen is hydrolyzed collagen. Due to the hydrolysis process, it’s broken down into smaller fragments, making it highly bioavailable.

When selecting collagen for hair, it is also worth paying attention to the presence of additional active ingredients that may positively impact hair health. In dietary supplements, look for compounds such as hyaluronic acid, vitamin C, biotin, and coenzyme Q10. Additionally, to support healthy hair, it is essential to maintain a diet rich in proteins and amino acids, which support the natural collagen production in the body.

Fish collagen or beef collagen for hair?

Consumers looking for collagen for hair often face the dilemma of whether to choose fish collagen or beef collagen. As it turns out, both types of collagen can be helpful in maintaining healthy hair.

Fish collagen typically has a smaller molecular mass, making it easier to absorb in the human digestive system. The better bioavailability means that the effects of collagen supplementation may be noticed more quickly.

Beef collagen found in supplements has a higher molecular mass but is characterized by a rich amino acid profile. It contains valuable endogenous amino acids such as proline, glycine, and hydroxyproline. These compounds are important components of proteins and also play a role in the reconstruction of keratin, the main building block of hair.

When deciding to supplement collagen, it’s also important to consider the allergenic potential of the product. Fish collagen for hair may not be suitable for people allergic to fish or seafood, which is an important factor in choosing the right product. In such cases, a good alternative may be beef collagen derived from bovine connective tissue, which is free from the allergenic marine protein and lacks the characteristic fish taste and smell.

What form of collagen should you choose for hair?

When wondering which collagen for hair loss to choose, it’s worth paying attention not only to the composition of the dietary supplement but also to its form. The choice of the appropriate preparation should depend primarily on your individual preferences and the goals you wish to achieve.

The most easily absorbed option is hydrolyzed collagen, or collagen peptides broken into smaller particles during hydrolysis. It most often comes in the form of tablets, powders, and liquids intended for direct consumption.

Collagen in tablets

One of the most common and convenient forms of supplementation to support healthy hair growth is collagen in tablets. Capsules are easy to take and have a long shelf life. Dietary supplements for hair growth in this form are perfect for people who lead an active lifestyle or those who do not like the taste of collagen in powder form.

Collagen in powder

Another popular form, due to its ease of use, is collagen in powder form. The preparation can be dissolved in your favorite juice, smoothie, or yogurt. Collagen for hair in drinking form is a convenient solution designed for people who do not wish to take supplements in the form of tablets or capsules.

Collagen in liquid form

This form of supplementation is characterized by fast absorption and a high content of collagen protein in a single dose. Liquid collagen is ready to drink and does not need to be mixed with other liquids. Due to its convenient packaging, it can be taken anywhere to support hair health. Collagen shots are not only used to support hair growth but also to slow down the aging process and improve skin appearance.

How to use collagen for hair?

Research shows that regular collagen supplementation supports the regeneration of hair follicles and helps maintain a properly moisturized scalp, which leads to improved hair condition and restores its natural shine. Additionally, collagen improves circulation in the scalp, which is crucial in stimulating hair growth. As a building block of hair, collagen improves its structure, making strands less prone to damage and loss.

Using collagen for hair involves regularly taking preparations in the form of tablets, liquid, or powder to be dissolved in water. The recommended daily dose of collagen is between 5 to 10 grams per day, but it can vary depending on age, body weight, and lifestyle. The preparation can be taken at any time during the day. There are no strict guidelines as to whether it should be taken in the morning, on an empty stomach, or during meals. Therefore, you can supplement collagen whenever it is most convenient for you.

When to expect first effects of using collagen for hair?

It usually takes several weeks to notice the effects of collagen supplementation. At first, the most noticeable changes are the restoration of shiny hair and reduced brittleness. The strands become shinier and more elastic. The full effects of collagen on hair are visible after about 8 to 12 weeks.

With regular supplementation, hair elasticity increases, hair loss decreases, and the growth of hair follicles accelerates. Taking collagen supplements also helps moisturize the scalp and improve its appearance. In addition, regular collagen use can help slow down aging processes, thereby delaying the graying of hair.

Summary: does collagen work for hair?

Collagen is a natural fibrous protein that plays many important roles in the human body. Besides maintaining the structural integrity of tissues and organs, it’s also involved in wound healing, cell growth and survival, and supports joint function.

Collagen also affects hair: it prevents hair brittleness, nourishes hair follicles and improves hair hydration. Numerous studies show that supplementing collagen may improve scalp condition and alleviate problems such as dandruff, excessive dryness, or inflammation.

The final choice of type and form of collagen to supplement is yours. If you seek to support your hair condition, remember to choose only products of high quality, with clear labels and without excessive fillers. A huge choice of versatile collagen supplements is offered by OstroVit. Products from this Polish manufacturer are distinguished by their excellent bioavailability and don’t contain any harmful additives. Thanks to regular testing in independent laboratories, they are safe to use and enable effective supplementation.
