Benefits of Collagen for hair health

The building block of many parts of the human body, including skin and hair, collagen is the most abundant protein found in us. It comprises 45 percent of the skin’s dry weight and makes 30 percent of the body's total mass.

But as you age, the collagen production rate of your body reduces, leading to aging signs like wrinkles, sagging skin and hair loss.

Collagen can help repair your damaged hair and replenish hair loss by promoting hair growth. It keeps your curls healthy and shiny.

When your body starts losing collagen due to age, collagen supplement can be your saviour.

Here are some of the main benefits of collagen for hair:

  1. Collagen adds volume

A research study done by a group of scientists in Japan found that the level of a particular type of collagen near the hair follicles decreases as we age, which results in hair loss.

Additionally, an amino acid called proline helps to protect the hair by keeping it safe from the damaging effects of the free radicals. Thus, collagen's antioxidant properties help to increase the volume of hair by strengthening your hair follicles.

  1. Collagen makes your hair shiny

As you grow old, your hair can become brittle and dull. This happens because beneath the hair follicles are sebaceous glands, which secrete oil to keep the hair moist.

Collagen plays an important role in the overall functioning of this entire process, resulting in lustrous and glossy hair.

  1. Collagen keeps your hair healthy

Collagen holds your dermal layer and hair follicles together, which in turn keeps your hair strong and healthy.

When the collagen production reduces due to aging, your hair follicle becomes brittle, while the dermal layers get dried up resulting in hair fall.

  1. Collagen reduces hair greying

Hair gets its natural colour from melanin, a pigment, that is produced by the melanin-producing cells. As we age, the melanin producing cells begin to die, thus turning the hair grey.

Although greying of hair is largely controlled by genes, free radicals that accumulate from stress, poor diet, and chemical build-ups from hair colour and shampoos can further cause hair greying. Collagen is known to have antioxidant properties that negates the hair greying from these free radicals.

Add a lot of Vitamin C rich food in your diet to boost the collagen production in your body. For example, bell peppers, oranges, strawberries, sprouts, etc are loaded with vitamins that can boost the body’s natural ability to produce collagen.

You can also add collagen supplements to your diet. Collagen supplements are usually in their broken-down form so that your body can absorb it quickly.

Collagen supplement is usually safe to use but some people might have a heartburn or stomach discomfort. Read the label to ensure your collagen supplement is devoid of MSG, E Numbers and other artificial ingredients and the ingredients match with the claims it makes.

How Much Collagen Should You Intake Daily For Hair Growth?

If you want to incorporate collagen supplements for hair growth, you need to first determine how much collagen is needed by your body.

Remember, not everybody type is the same and hence the requirement of collagen also varies. For example, if you are exercising regularly, you tend to break down collagen faster. Similarly, if you are under stress, you may lose collagen faster.

Depending on your body's requirement, you can adjust collagen requirements. While determining the collagen amount you want to intake, consider your dietary sources as well. For example, salmon skin is a rich source of building collagen. If you are a regular salmon eater, adjust your collagen supplement intake accordingly.

If you are looking for collagen supplements, opt for the unflavoured and pure form of collagen.


The golden rule is to incorporate as many grams of protein in your diet as you weigh in pounds.

Collagen is the most important protein that holds your hair together, gives it volume, and retains its natural moisture. As you age, you may start losing collagen, which leads to hair fall. Collagen supplements are a great way to replenish the lost collagen and give your hair health a boost. However, all supplements should be taken only after consulting with a doctor.

Note: please check with your doctor if you have any medical concerns.
