Scientifically Proven Threonine Benefits For Treating Hair Loss

Scientifically Proven Threonine Benefits For Treating Hair Loss

Hormonal imbalances, aging and underlying medical conditions can cause your hair to become thin and patchy over time. Fortunately, an amino acid called threonine can treat some hair loss symptoms and improve your scalp’s health, which is why the Divi experts added it as an integral ingredient to Divi’s Scalp Serum. 

Clinical evidence has demonstrated that threonine and its fellow amino acids can produce thicker, healthier hair for men and women. Divi’s product research specialists have included this clean ingredient in our Scalp Serum to help customers achieve a scalp that supports hair growth. Read on as we unpack the science behind this ingredient and explain why we recommend trying our threonine-infused Divi’s Scalp Serum to help manage hair loss.

Threonine: An Essential Amino Acid

Amino acids are molecules tasked with creating proteins in the human body. Essential amino acids are not produced by our bodies, and threonine is an essential amino acid. Instead, it must come from nutrients in foods we consume, such as chicken, lamb, beef, turkey, wild salmon, dairy products, seeds, nuts and soybeans or supplements (both oral and topical). 

Threonine serves as a building block enabling the body to create proteins. Threonine is also a precursor to the creation of other amino acids, such as serine and glycine, which are necessary for collagen production. As such, it plays an essential role in several physiological processes, including:

People who do not metabolize threonine properly can experience deficiencies that weaken their immune systems and cause digestive problems. One study suggests that adults should receive around 15 mg of threonine daily to prevent these complications.

This amino acid promotes anti-aging properties that tighten and hydrate the scalp. Lab scientists, including Divi’s product research specialists, use extracted threonine in Divi’s Scalp Serum.

Threonine in Hair Products

Hair products often contain harsh chemicals and fragrances that can damage your hair. If you struggle with dry or itchy skin, traditional shampoos and conditioners may irritate your scalp.

The harsh reality of the hair product landscape is why Divi created our Scalp Serum – to give people with hair loss conditions a safe, vegan-friendly, science-backed product to create an environment for their hair to prosper. Threonine is an essential component to this objective.

As an important element in Divi’s Scalp Serum, threonine is a clean ingredient that hydrates the scalp, moisturizes hair strands, and builds stronger hair. The topical application of threonine enables this amino acid to enter the body quickly and directly fortify hair roots.

Many products that treat frizzy hair include threonine because of its anti-static properties. However, threonine is most effective when paired with other amino acids in a balanced, synergistic formula, like the one we’ve developed for Divi’s Scalp Serum.

Enhancing Your Hair Growth with Threonine and Other Ingredients

Divi’s scientists determined the optimal ingredients for treating your scalp and addressing hair loss with our Scalp Serum. These include a proprietary blend of protein-building and healing amino acids, such as arginine, glycine, serine, valine, proline, isoleucine, histidine, phenylalanine and others that enhance threonine’s benefits for treating hair loss. Our scientifically proven Divi’s Scalp Serum includes other hair-enriching solutions capable of benefiting you.


Unlike essential amino acids like threonine, peptides are naturally occurring molecules in the body. Peptides contribute to creating proteins like elastin, collagen and keratin that promote hair health and support the functions of hormonal glands.  

We synthesize copper tripeptide-1 in our formula to reinforce threonine’s protein-building properties. Studies suggest that this ingredient encourages longer hair growth and can reduce the symptoms of androgenic alopecia, which is the most common hair loss condition in men. Copper elements may also improve the quality of the melanin in hair follicles, slowing down the process of hair graying as you age.

Peppermint Oil

Peppermint oil is a frequent additive in hair-growth formulas. This product helps deepen follicles and treat the symptoms of skin conditions like eczema. As the name suggests, it is derived from the peppermint plant. When threonine and peppermint solutions metabolize together under the skin, they can provide effective relief for skin disorders. Threonine builds proteins to strengthen skin cells, and peppermint fights off allergic reactions and opens follicles up to receiving nutrients more efficiently. 

Mint Leaves

Tea Leaf Extract

Hair products that contain green tea leaf extract help supply the skin with nutrient-dense blood. Combining this ingredient with threonine can lead to healthier roots and skin colorization. 

Tea Tree Oil

Eucalyptus Extract

Eucalyptus is another supporting ingredient that mirrors threonine’s benefits for treating hair loss. This antifungal oil can prevent scalp inflammation and eliminate dangerous parasites in your hair. Eucalyptus extract clears the way for threonine to enter the skin and begin moisturizing hair roots.


The Benefits of Using Threonine on Your Hair and Scalp

Divi’s Scalp Serum is infused with threonine, promoting comfort and beauty. Its hydrating properties reduce the appearance of aging and protect the scalp against harmful microbial elements. Threonine may contribute to improving a few conditions.

Itchy Scalp

Do you notice that your hair is drier in the morning than it was the night before? Your scalp can lose moisture quickly without proper treatment. Even being out in the sun too long can dehydrate your follicles and prevent you from looking your best. Topical solutions containing threonine can treat the symptoms of a dry, itchy scalp by settling into pores and moisturizing follicles without making the hair look or feel greasy. 


Dandruff flakes are an unfortunate side effect of dry scalp disorders. This condition can also be challenging to treat. Some hair care solutions claiming to treat dandruff can damage hair strands in the process. Threonine-infused hair care can protect both your scalp and your follicles. This amino acid aims to eliminate unsightly flakes over time and improve the texture of your strands. 


Dry scalp and dandruff may also result from a skin condition called psoriasis. Those with psoriasis may experience dry or scaly patches around their hairline, skin discoloration and a burning sensation near the affected areas. This chronic disease can last a lifetime and often flares up during stress or heat exposure.

The proper application of threonine can alleviate pain and reduce the risk of significant outbreaks. Threonine contains soothing properties that may reduce inflammation during psoriasis flare-ups and protect hair follicles from damage. 

Menopausal Hair Loss

Dramatic hormonal shifts cause hair loss in women. Menopause often slows hair growth and can cause strands to fall out. Threonine helps generate elastin and collagen, two proteins that facilitate healthy hair growth. Elastin provides stretchiness to your skin, which sustains your roots. It also makes it easier for your arteries to transport blood throughout the skin.  

Having more elastin and collagen in your body can prevent hair loss during menopause and give you a more youthful look. Collagens create new skin cells and support the structure and strength of your scalp. Additionally, they play a significant role in replacing dead skin cells.

How to Apply Threonine

Divi’s Scalp Serum can be easily applied to your hair in just a few minutes. Apply ¾ of a dropper directly onto your scalp, either all over or specifically where you have thin and patchy spots of hair.

Massage Divi’s Scalp Serum into your scalp—you may notice a tingling sensation. This feeling results from a combination of threonine and other clean ingredients settling into your follicles and opening up your scalp.

Follow this regimen once a day. If you stop applying threonine-infused products, you will likely see your symptoms re-emerge. It’s important to continue using the treatment regularly for the best results. Our experts recommend using Divi’s Scalp Serum for at least 90 days to get full results.

Relevant Studies

Researchers worldwide continue to study the effects of threonine and other essential amino acids. Some studies focus on how threonine supports intestinal health and nutrition in animals, and others explore amino acid deficiencies that result in hair loss.

We completed our own eight-week, single-blind study to determine the effects of threonine-infused products on adult men and women. Nearly all participants noticed improvements in scalp comfort after using the product. Additionally, they agreed that their hair felt healthier and cleaner.

People who use our Scalp Serum often observe thicker, fuller hair just a couple of weeks after their first application. Although each person may respond differently to treatment, threonine consistently demonstrates positive results.
