The Benefits of Threonine for Hair Growth

Threonine is an important ingredient in Divi’s Scalp Serum due to its moisturizing, protective, healing, skin-replenishing and anti-aging properties.

In this article, we will look at the role of threonine in cultivating your scalp and promoting hair growth and explain its importance as an active ingredient of Divi’s Scalp Serum.

What is Threonine?

Threonine is an essential amino acid used in cosmetics and personal care products. Essential amino acids cannot be made in the body and thus need to be obtained via other sources. Divi uses it primarily for its ability to promote hair growth via protein balance maintenance.

Threonine is particularly important in protein synthesis and protein metabolism, and hair growth is one of the biological functions of threonine.

Amino Acids and Hair Growth

Proteins make up around one-fifth of the human body. Amino acids are the building blocks of proteins, so their importance cannot be overstated.

Both essential and non-essential amino acids are needed to form key hair growth proteins, such as keratin. Additionally, since amino acids are the main constituents of hair, they also impact factors such as hair shaft structure, appearance and behavior.

Threonine also aids the production of other amino acids, like glycine and serine, both of which are also found in our Scalp Serum. Glycine in particular is important for the production of collagen, which is necessary for hair growth and reducing hair loss.

Benefits of Threonine for Hair Growth

Moisturizing

One of the most well-known benefits of threonine is it keeps hair hydrated and well-nourished.

Conditions the Strands

Threonine is an excellent antistatic agent, supporting hair follicles to retain their shape, especially in cases of dry, frizzy hair. The amino acid fills in damaged gaps in the outer hair cuticle, which is the protective layer of the hair strand.

Rated Safe

High-profile regulatory bodies, such as the FDA, Cosmetic Ingredient Review and Environmental Working Group (EWG) Skin Deep Cosmetics Database, have rated threonine as safe for use in personal care products. Divi uses science-backed ingredients that have undergone clinical trials and been deemed safe and effective.

Alternative to Keratin

Keratin is a protein that makes up the hair, skin and nails. Because of this, hydrolyzed keratin has been used in hair supplements for many decades. Recent years have seen a growing push for supplements to be made without animals being involved in the process. As a result, vegetable-based alternatives have become a popular solution. Threonine is a key component of vegetable-based alternatives to keratin.

Adds Volume

When added to shampoos and serums, amino acids can add body and volume to the hair. Who doesn’t want that?

Threonine in Divi’s Products: How Does It Help with Hair Growth?

There’s a lot of science regarding threonine, but essentially, it's a key part of our scalp product formulas because it helps regulate the scalp's moisture and keep each targeted hair follicle hydrated. This enables the scalp to provide an ideal environment for hair growth and reduce excessive hair shedding.

Hair and Scalp Conditions Treatable With Threonine

Itchy scalp – Occasional scalp itch is natural; however, if you find that you're scratching too frequently, extra measures may be needed to alleviate the itch. Threonine, especially in the form of an anti-itch shampoo, can relieve an itchy scalp.
Dry scalp – Threonine can soothe a dry scalp by keeping it hydrated, thus making the scalp conditions ideal for hair growth.
Dandruff – Threonine has been shown to eliminate dandruff, a skin condition causing the skin on the scalp to flake.
Scalp psoriasis – Threonine can also help combat the dry, scaly patches associated with scalp psoriasis.
Nutritional factors – Threonine keeps the hair follicles healthy and, because it makes an excellent anti-static agent, it does a good job of conditioning and taming dry, frizzy hair.
Menopausal hair loss – Threonine serves as a substrate for protein synthesis and assists in the formulation of elastin and collagen.

Threonine supports many aspects of hair health, and, combined with the other ingredients in Divi’s products, it can help address many conditions that lead to hair loss.

Can Too Much Threonine Affect Hair Growth?

There isn't much research on overapplication of threonine in relation to hair growth. However, as a matter of caution, it's always advisable to apply threonine and other amino acids in measured amounts. Divi’s lineup of scalp care products include a measured and safe amount of threonine, so you don’t have to worry about any negative effects to your scalp or health.

Possible Side Effects of Threonine

Although the EWG Cosmetics Database considers threonine to be a low-hazard ingredient, it's important to use the recommended dosage. There is little to no risk of side effects with topical application. Divi’s formula has been carefully crafted to ensure all the ingredients are perfectly balanced and safe to use.

FAQs

What Foods are High in Threonine?

Threonine is found in high quantities in the following foods: cottage cheese, lentils, lean beef, poultry, collagen, gelatin and black turtle beans. Maintaining a balanced diet is key to both human hair growth and skin health.

Can You Increase Your Hair Follicle Count?

You can't change the number of hair follicles you have, as that is genetically determined. However, you can improve your hair density by activating dormant hair follicles.

The ideal way to do this is by improving your nutritional habits and reducing hair damage by avoiding both permanent dye and heat drying. This can be coupled with scalp health solutions, such as Divi’s Scalp Serum.

Is Threonine the Same as Theanine?

Don’t confuse theanine and threonine, as the two amino acids are different. Theanine is a nonessential amino acid widely known for having relaxing but non-sedative properties. On the other hand, threonine is an essential amino acid necessary for muscle growth, nervous system, liver function and hair growth—of course.

What are Hair Follicle Stem Cells?

These are stem cells derived from the hair follicle bulge with the potential to differentiate into a variety of cell types. Common differentiations include the interfollicular epidermis, hair follicle structures and sebaceous glands.

What are the Signs of a Threonine Deficiency?

People often discuss the results of excessive threonine intake and tend to overlook the implications of a deficiency. Although threonine deficiency is rare, it may occur in people who do not consume a sufficient amount in their diet.

Those with a threonine deficiency may experience digestive issues, irritability, confusion, increased liver fat and poor nutritional absorption.

Final Thoughts

Choosing a scalp care product can be quite a complicated process. With the multitude of products on offer, it's hard to discern which ones can actually promote hair growth while catering to your individual needs. Luckily, Divi’s Scalp Serum, Shampoo & Conditioner can make such issues a thing of the past.

Our proprietary blend in each of these three products is carefully formulated to best utilize powerful ingredients such as proline, tea tree oil and, of course, threonine. Finally, don't forget that living a healthy lifestyle and maintaining a balanced diet are key components of promoting hair growth and mitigating hair loss.
