Proline for Hair Growth & Hair Health: Benefits, Studies

Published on November 18, 2021. Last Updated on November 18, 2021.

What is Proline: Proline, also known as L-Proline, D-proline, or DL-proline, is one of twenty non-essential amino acids produced and synthesized within the human body. Proline is involved in the human body’s production of collagen and cartilage. Due to proline’s direct relationship in collagen and cartilage production, proline has been used in many anti-aging, cosmetic, and beauty products to help skin, hair, nail health, and more. In addition, proline is also a main component of keratin – which is the main building block of hair and hair cells. Today, modern science is exploring the uses of proline, proline benefits for hair, and its possible use to help hair growth, combat hair loss, and other forms of hair growth-related issues.

Benefits of Proline for General Health

As stated by WebMD, proline is an amino acid. It is part of the building blocks necessary to create new proteins.

Specifically, proline is utilized for skin healing, due to its relationship with collagen.

Collagen is particularly important to the topic because it is used to make skin, bones, and joints.

In a 2010 published review, researchers state that “dietary proline is necessary for promoting tissue repair and nitrogen balance in both animals and humans with wounds and burns.”

Due to this finding, we can conclude that proline helps skin regeneration and the building of new skin tissues to help repair wounds and scarring.

Having enough proline in the body contributes to a healthier and younger-looking, feeling body due to proline’s role and ability to create, regenerate and replace new skin and hair-related protein cells as further described below.

Benefits of Proline for Hair Growth & Hair Health

Proline, which can be found in high concentrations in cottage cheese, can possibly help aid hair growth and hair health in general.

When looking for causes and solutions to alopecia, or other forms of hair loss, it is best to first examine your diet, habits, stress levels, and medications to help identify and get to the root of the problem.

In some cases, certain key missing nutritional ingredients needed for hair growth may be what you need to help improve your hair health.

Let us take a look at proline benefits for hair health and possibly hair growth.

Proline is a major amino acid that is needed by the human body to produce collagen and keratin.

In a 2010 published study in Springer Research Journal, researchers state how proline is a “major extracellular component in connective tissues [such as] skin, tendon, cartilage, vessels of the vascular system, and bone.”

As explained further below, collagen and keratin both have direct and indirect ties to hair growth and overall hair health.

Proline & Collagen for Better Skin & Hair Health

As stated by Cedars-Sinai, collagen is a protein that serves as one of the primary building blocks for bones, skin, hair, muscles, tendons, and ligaments.

Additionally, collagen is known as an anti-aging protein and can be used to help slow down age-related hair loss. Having more collagen in skin tissues replenishes skin cells and keeps skin firm and elastic, which also helps hair follicles grow on a healthy scalp.

As stated by Wikipedia, one-sixth of collagen is composed of proline.

Therefore, proline is a major component needed in collagen production, and collagen is a major building block of skin, as well as its youthful appearance and glow.

Yet, in addition to being the main component of skin cells, and a primary factor in skin appearance, health, and glow, healthy and optimal collagen production can also help stimulate hair follicles, helping produce more hair growth. This is why proline benefits for hair can be powerful, as it has a direct impact on hair follicles and hair growth.

It is also important to note that with age and its due weathering via oxidation, the body tends to produce less collagen. In fact, the body begins to start losing collagen starting in the mid-20s.”

All of these reasons are why collagen is known as the “fountain of youth.”

Not having enough proline, and eventually, collagen can have negative effects on your health and beauty including:

  1. Early signs of aging
  2. Wrinkled skin
  3. Weak Hair
  4. Weak Nails
  5. Less Joint Mobility
  6. Brittle Bones

On the other hand, there are plenty of health benefits of collagen related to hair health and hair growth such as:

  1. Providing amino acids to build new hair strands
  2. Helps reduce oxidative damage to hair follicles
  3. May help prevent hair thinning due to aging
  4. May help stop hair greying

How to Maximize Proline’s Benefits for Hair Health

Additionally, if you are looking for proline benefits for hair or skin specifically to help boost collagen production for skin, beauty, hair health, and hair growth, it is useful to understand that vitamin C is also needed to help combine with the proline to produce collagen.

Therefore, if you are looking to reduce the effects of antioxidation and aging, it is best to have enough proline in your diet, either from foods or from oral supplements.

More so, it may help to use natural oral supplements which contain both enough proline and vitamin C in order to combine and synergize their effects together to achieve maximum health and beauty results for your skin and hair.

Proline & Keratin for Hair Growth, Hair Health

Additionally, proline is also used to help create keratin – the main component which is used to create new hair strands. This is another reason why proline benefits for hair are plentiful and powerful.

As stated in a 2018 study published on “Health Improvement of Human Hair and Their Reshaping Using Recombinant Keratin K31” researchers stated that application of keratin resulted in “marked improvements in smoothness, diameter, and mechanical strength of damaged hair.”

Keratin, as a “major component of the hair cortex, contributes to the strength of the hair shaft.” Due to keratin’s role as a “basic building block of [hair],” it has been used in many hair and cosmetic products as part of a growing and widely popular health and beauty trend.

Therefore, if you are looking for a natural oral hair supplement to help improve your hair health or possibly help improve hair growth, it is recommended that you take an oral supplement that contains at least proline, keratin, and vitamin C to help maximize all of these powerful ingredients’ beneficial effects on your hair.

Signs You May Need Proline

If you are an endurance athlete, you may benefit from proline supplementation – especially so if you are a long-distance runner. Extensive endurance training can lead to lowered levels of proline and therefore in this case a high proline diet or proline supplementation is recommended.

Some other specific symptoms of low proline levels in the body can include:

  1. Wrinkles
  2. Sores
  3. Slow Healing Wounds
  4. Chronic Joint Discomfort

Due to proline’s role in creating new cells, proteins, skin cells, bones, connective tissues, and more, not having enough proline intake can lead to disruptions in creating these new cells, as well as possible joint or skin problems.

Foods High in Proline

Proline can be found in both animal foods and plant foods. Foods that are high in proline include:

  1. Cottage Cheese
  2. Gelatins
  3. Turkey
  4. Beef
  5. Chicken
  6. Egg Whites

Proline Dosage Recommendations

As stated by WebMD, the appropriate dosing of proline depends on several factors, such as the user’s age, health, and other conditions.

Currently, there is not enough medical and scientific evidence to determine the appropriate range of dosage for proline.

In general, the average human diet consumes about 5 grams of proline daily. Primary sources of proline include protein-rich foods such as meat, fish, and dairy. Proline can also be taken as a supplement.

Proline Safety Profile

According to the EWG, proline scores a 1 on the safety rating score which states that it has little to no risk for cancer, developmental and reproductive toxicity, nor any allergies or immunotoxicity.

Unfortunately, due to the effects of aging and time, or even stress, our hair health can deteriorate due to these factors. If you are experiencing symptoms of hair loss, alopecia, hair thinning, hairline recession, or any other hair-health-related issues, you may relate with Diane’s story and how she was able to overcome these challenges using natural, botanical means with Dr.UGro Gashee Topical Pomade and Oral Supplements for hair health.

Meet Diane: For Diane, it was possibly the heart-wrenching passing of her parents and siblings that had possibly attributed to her hair loss. Looking for a solution to maintain or improve her hair health, some of the symptoms of hair loss and challenges that she had to deal with include:

  1. Decrease in quality of hair
  2. Decrease in quality of hair texture
  3. Patchy hair
  4. Frail hair
  5. Sparse hair
  6. Parts of scalp exposed
  7. Lack of volume on edges & temples

The Beginning of Diane’s Journey in Recovering Her Hair Health

In Diane’s case, it all started with her noticing little changes in the texture and thickness of her hair.

Yet, what seemed to be little changes, over time, grew to a larger problem.

Eventually, Diane began to see in the mirror that her scalp had begun to show exposed patches and that the hair along the edges and temples of her hairline was beginning to grow short, losing volume, overall fullness, and was all beginning to break.

But the beginning of Diane’s battle for better hair did not stop there. She had tried multiple different hair care and hair growth products, with no significant or satisfying results.

At this point, Diane knew that something had to change. It was time to find help.

But what was the root cause of Diane’s sudden deterioration in hair health?

The Root of the Issue: How Stress Can Lead to Worsening Hair Health

As Diane’s husband had pointed out, the past few months for Diane had not been easy. Rather, Diane was facing a hard point in her life due to recent family tragedies that had hit her consecutively. As many of us know, not only nutrition, but our mental health, can lead to changes in our hair health – such as hair loss, hair thinning, breakage, and other symptoms of hair loss that Diane faced.

But Diane was strong, and she was persistent. Even in this moment of struggle, Diane was able to personally triumph over this personal tragedy, and with the help of the internet, she was able to find Dr.UGro Products: Pomade Topical & Oral Supplements, to great results.

In the video below, you can watch Diane’s testimonial on Gashee Pomade and Oral Supplements, and how they have helped her in her journey towards better hair health.
