Acetyl Tetrapeptide-3 for Hair Growth: Is It Effective?

Acetyl Tetrapeptide-3 for Hair Growth: Is It Effective?

Society is obsessed with hair. From the biblical character Samson, who derived strength from his hair and said he’d lose his power if his head was shaved, to the endless chatter on social media about celebrities’ signature styles, hair is a constant topic.

Why the obsession? Well, our hair is one of the most prominent (and controllable) aspects of physical appearance – true for both men and women.

A thick head of well-maintained hair connects with perceptions of health, youth and fertility. Having great hair makes us more attractive and is a huge confidence-builder.

Age, illness, stress and environmental factors can contribute to thinning hair and hair loss. Researchers have been working to find solutions to stop and reverse hair loss, and as a result, many ingredients have been discovered that contribute to hair growth and scalp health, including acetyl tetrapeptide-3.

This ingredient is one of many in Divi’s Scalp Serum, and in this article, we’ll explore how it promotes healthy hair growth.

What Is Acetyl Tetrapeptide-3?

This mouthful of a word refers to a string of amino acids affecting the structure of bodily tissue. Amino acids are vital to countless functions, including the formation of essential proteins.

Specifically, acetyl tetrapeptide-3 stimulates tissue regeneration by causing collagen to synthesize in the tissue that connects hair follicles to the scalp. As a result, acetyl tetrapeptide-3 has been clinically proven to help anchor hair follicles to the scalp, slowing or preventing hair loss.

How Supporting the Scalp with Acetyl Tetrapeptide-3 Can Prevent Hair Loss

We shed 50-100 hairs from our heads every day. This daily hair loss isn’t a cause for concern, because each hair follicle, including those on other parts of our body, has a natural life cycle. When that life cycle ends, the hair follicle separates from the scalp, and a new strand (theoretically) takes its place.

Thinning hair or hair loss can result when hair follicles separate from our heads faster than new follicles regenerate.

There are several root (pun intended!) causes of this process, including alopecia areata. This autoimmune condition results in the immune system attacking hair follicles and causing them to break down. As the hair follicle structures weaken from the attack, they break down and separate from the scalp. Approximately 2% of the population will struggle with alopecia areata.

Therefore, if you can strengthen those underlying follicular structures, you can maintain the hair you already have and potentially stimulate new growth.

Benefits of Acetyl Tetrapeptide-3 on Your Hair and Scalp

A recent Journal of Cosmetic Science study reported the numerous benefits of acetyl tetrapeptide-3. Most importantly, the study found that within just eight days of topical application, this ingredient led to a 35% increase in hair follicle length.

In addition, the study found that acetyl tetrapeptide-3 provides even more benefits to hair and scalp health. Among other effects, it:

  • Stimulates follicle tissue regeneration
  • Strengthens the structures surrounding hair follicles
  • Anchors hair fibers to the scalp
  • Strengthens strands of hair
  • Slows down the follicle aging process
  • Contributes to healthy skin and scalp
  • Accelerates hair growth
  • Improves circulation in the scalp
  • Increases collagen production

Furthermore, and perhaps most importantly, acetyl tetrapeptide-3 works synergistically with other ingredients in Divi’s Scalp Serum to strengthen hair and promote new hair growth.

Which Conditions Can Acetyl Tetrapeptide-3 Address?

The term alopecia often causes confusion because it encompasses all types of hair loss, including alopecia areata. Although a long laundry list of conditions includes hair loss as a symptom, the underlying issue leading to hair loss can be addressed through similar means.

Stress, for example, is frequently attributed to rapid hair loss. The reason is the hormone cortisol floods the body when we feel stressed. Stress sends the body into “fight or flight” mode, where non-essential functions are turned off in favor of survival.

As you might have guessed, this means hair growth can be put on pause. Instead of growing healthy locks, the stress hormone cortisol causes hair follicles to enter the resting phase. At the same time, the body diverts those hair-growing resources toward battling the modern equivalent of jungle beasts.

Shortly afterward, the hair follicle detaches from the scalp, and if you are still stressed out (meaning you have a lot of cortisol in your system), new hair growth may not occur. While acetyl tetrapeptide-3 can’t eliminate stress from your life or cortisol from your body, it can help prevent the follicle from detaching prematurely.

In addition to stress, acetyl tetrapeptide-3 can help anchor follicles in place, preventing separation due to other common causes of hair loss:

  • Aging – As we age, our follicles can shrink or become skin instead of hair follicles. Preserving the underlying hair follicle structure with ingredients like acetyl tetrapeptide-3 can help with this issue.
  • Pregnancy – Building a tiny human can take a toll on the body, as resources are increasingly allocated toward the baby’s health. Often, this results in a pregnant woman’s hair going into a resting phase, putting both growth and shedding on pause. As a result, pregnant women might have thicker hair during pregnancy, which reverses into shedding after birth. The most pronounced effects tend to happen about three months after delivery. Women who have recently given birth can turn to acetyl tetrapeptide-3 to stimulate the proteins that make up the structure of hair follicles, slowing or stopping the shed.
  • Thyroid conditions – An overactive or underactive thyroid can wreak havoc on several bodily functions, including hair growth and loss. In addition, some medications used to treat thyroid conditions can also contribute to thinning hair. The condition or medications can interfere with the process of new hair growth, where new follicles replace the old as strands of hair shed from your head. Again, the anchoring properties of acetyl tetrapeptide-3 can be instrumental in preserving hair health and thickness.
  • Testosterone imbalances – When testosterone levels spike, the body creates excess DHT (Dihydrotestosterone). The effect is a shrinkage in the size of the hair follicles. Acetyl tetrapeptide-3 addresses this issue by supporting the structure of your follicles and helping them maintain a normal size.
  • Other hormone imbalances – Hormone imbalances in men and women can cause thinning hair and receding hairlines. Applying Divi’s Scalp Serum with acetyl tetrapeptide-3 can offset the effects of hormonal hair loss with its follicle-anchoring properties.

No matter what has triggered your hair loss, acetyl tetrapeptide-3 is an effective weapon for strengthening the structure of your hair follicles, providing hair with a stronger anchor to your scalp.

How Acetyl Tetrapeptide-3 Supports Hair Growth and Prevents Hair Loss

Acetyl tetrapeptide-3 works well to strengthen your hair’s structure and encourage the adherence of healthy hair follicles onto your scalp. Instead of constantly losing hair and watching your hairline lose the battle against age or health conditions, acetyl tetrapeptide-3 keeps your follicles in the fight longer, giving you healthier strands of hair that stay on your head longer.

This string of amino acids is a star ingredient in topical applications because its use stimulates protein synthesis, which strengthens the follicle and encourages better hair growth. It can also widen hair follicles, allowing each strand to be thicker.

So, even if you don’t end up with new follicle growth, you’re likely to experience a noticeable difference in your hair’s thickness through the use of acetyl tetrapeptide-3. In the many acetyl tetrapeptide-3 success stories, the primary result is thicker and fuller hair, usually due to wider hair follicles.

How Acetyl Tetrapeptide-3 Works Synergistically with Other Ingredients

Divi’s Scalp Serum contains over 25 clean ingredients which have been researched and shown to promote the conditions necessary for a healthy scalp and hair growth.

Divi’s Scalp Serum combines acetyl tetrapeptide-3 with other ingredients, including:

Scientific Studies Highlight the Effectiveness of Acetyl Tetrapeptide-3

Scientists have been actively studying hair loss causes and solutions for decades, and although there’s no shortage of options, the question of efficacy is always at the forefront.

One promising recent study published by the Journal of Clinical and Aesthetic Dermatology compared the topical application ingredient acetyl tetrapeptide-3 with a leading over-the-counter solution that was backed by years of successful results.

The question was whether a naturally occurring ingredient like acetyl tetrapeptide-3 could compete with a synthetic solution.

The research followed 32 men and women over 24 weeks (approximately 6 months) in a triple-blind study to consider the effects of an acetyl tetrapeptide-3 solution on androgenetic alopecia compared to the leading commercial solution.

As a quick reference, androgenetic alopecia is a genetic type of hair loss that manifests as male-pattern baldness in men and an overall thinning of the hair in women.

The study results included before and after pictures, with the most dramatic results occurring within the first 12 weeks. There was favorable progress in all hair measurement variables, including: 

  • Hair mass index
  • Target hair count
  • Terminal hair count change percentages
  • Patient satisfaction
  • Safety assessments

How to Use Acetyl Tetrapeptide-3

Acetyl tetrapeptide-3 can be applied topically to the scalp. When using Divi’s Scalp Serum, apply 3/4 dropper of the Serum to your entire scalp, focusing on areas where you notice any thinning or hair loss. Apply it either in the morning or evening. After application, let our Scalp Serum soak in and work its magic on your scalp.

Is Acetyl Tetrapeptide-3 Safe for Everyday Use?

Any time you introduce something new to your body’s largest organ (the skin), it’s important to consider whether there are any safety issues or side effects. Acetyl tetrapeptide-3 is used in a multitude of products designed to promote healthy hair, including: 

  • Shampoos and conditioners
  • Hair treatments and serums
  • Styling gels
  • Hairspray
  • Mascara and brow liners

There are no documented adverse side effects to using acetyl tetrapeptide-3 topically (on the skin), but it can irritate your eyes. Furthermore, it is harmful if swallowed, so we recommend you wash your hands after applying it to your scalp to protect your eyes and mouth.

Acetyl tetrapeptide-3 has also received a top safety rating from the Environmental Working Group (EWG), a team of scientists that evaluates ingredients in consumer products and reports on concerns associated with using the products containing those ingredients.

The Bottom Line

Thinning hair and baldness affect both men and women. Half of men often show signs of baldness by age 30 and are completely bald by age 60. Women are also prone to thinning hair.

Finding an effective hair growth solution to combat this problem can boost confidence and keep hair loss at bay. Combining the powerhouse hair follicle-strengthening ingredient acetyl tetrapeptide-3 with our proprietary blend of other ingredients, Divi’s Scalp Serum cultivates the healthiest environment for hair growth, promoting thicker, fuller and healthier hair.
