There are various hair treatments available, but you have to choose the right one for your problem.

By the end of this article, you will understand:
– What keratin and collagen actually are,
– The benefits of keratin and collagen treatments, and
– The most suitable choice for treating hair loss.

What is Keratin?
In order to make the right choice between keratin vs collagen treatments, you have to first understand what keratin and collagen actually are. Let’s start with keratin. As a matter of fact, keratin is a type of protein which builds your hair, skin, and nails. It is also commonly found in internal glands and organs. It is basically a protective protein, so it is less vulnerable to scratching and tearing compared to other types of proteins.

Since keratin is the structural building block of hair, many people believe that keratin supplementation can help to strengthen hair and improve the look. Thus, keratin has become popularly used in oral supplements, shampoos, conditioners, and serums that target human hair. For example, Hairfluence does contain keratin (see Hairfluence vs Hairfinity here).

Benefits of Keratin
For sure, keratin vs collagen offer different uses and benefits. Keratin may be used for oral consumption or for an external treatment. When consumed orally, it may come as powder or capsule supplements. Keratin consumption is primarily useful for strengthening your hair, skin, and nails so that they will not break easily. It may also make the hair smoother and shinier.

Meanwhile, when used for an external treatment, keratin can deliver more apparent and more immediate benefits. According to, people who use keratin treatments for their hair say that their hair becomes smoother and easier to manage. This is because of keratin’s ability to coat the hair and create a smooth surface. It also makes the hair shinier.

Keratin treatment can make the hair look thicker with more volume. This is great if you want to make your hair look fuller, or if you want to cover a bald/thinning spot. Keratin may be used to straighten the hair by making it less frizzy and easier to style.

Note that keratin supplementation and treatment don’t necessarily promote hair growth. It strengthens the hair and improves the look, but it does not make hair follicles grow better. This is why keratin is not really good for dealing with hair thinning and hair loss, except for covering the bald spot/thinning.

Side Effects of Keratin
Most salon keratin treatments contain high amounts of formaldehyde, which can be as much as five times over the safety standard. Formaldehyde is a dangerous substance that may cause adverse side effects. Some hair salon employees even experienced respiratory problems and nosebleeds due to inhaling the fumes of keratin treatments for long periods. Pregnant women and people with respiratory problems or sensitivity to formaldehyde should avoid keratin treatments.

Continuous keratin treatments may also damage the hair. Since keratin binds to the hair, they may make the hair easy to break if repeated for a long period of time. Meanwhile, oral keratin supplements are generally safe, but excessive consumption may create too much protein build up in the body.

What is Collagen?
On the other hand, collagen is a long-chain amino acid which happens to be the most abundant protein in a human body. It is commonly found in bones and connective tissue. It makes a large part of the hair, skin, and nails. Actually, the body produces collagen naturally, but the production rate declines over time due to aging and lifestyle factors, including poor diet, stress, and gut imbalances.

Collagen is responsible for the skin’s elasticity, the hair’s strength and flexibility, and the connective tissue’s ability to hold things in place. Hence, collagen is often recommended for improving the health of the hair, skin, nails, bones, and joints. You can find it in various dietary supplements and treatments.

Benefits of Collagen
One important thing to know about collagen is that it provides the most benefits from the inside, not the outside. In other words, if you want to use collagen to promote your hair health, your best bet is taking an oral supplement. Collagen in an external topical treatment offers little benefits.

Collagen is highly useful for promoting hair growth and hair regeneration. It has anti-oxidant properties that can reduce the detrimental impacts of free radicals on hair follicles. For your information, free radicals naturally occur in the human body as a result of various metabolic processes. They may damage the hair follicles and cause hair loss. However, if you have a sufficient amount of collagen in your scalp and hair shaft, you can strengthen your hair follicles and prevent hair loss.

Additionally, collagen is also able to improve your hair thickness and volume. This is because collagen can help to maintain the diameter of each individual hair shaft. Hence, it makes the hair fuller and thicker.

Keratin vs collagen offer different additional benefits. One great thing about collagen is that it can help to maintain your skin’s smoothness and elasticity. It also maintains bone and joint health, hormonal balance, and digestive health. This is why collagen is a good ingredient for a daily dietary supplement.

Side Effects of Collagen
Some collagen ingredients are derived from marine fish, which is a common allergen. This is not a problem if you don’t have any allergy. However, if you are allergic to seafood or fish, you should be careful when choosing your collagen supplement. Make sure to check the ingredient label, and choose a product that doesn’t use marine collagen.

For treating hair loss, taking a good collagen supplement is more recommended. Collagen is able to promote hair growth and regeneration, which are very important to combat hair loss. In addition, it can also make the hair thicker and fuller. Note that collagen works best from the inside as a dietary supplement, and not from the outside as a topical treatment.
