Can MK-677 Really Boost Hair Growth?

hair supplements

Hair loss is a common concern for many individuals, affecting both men and women alike. It can be a source of frustration and self-consciousness, leading to a search for solutions to promote hair regrowth and thickness.

In recent years, a compound known as MK-677 has gained attention for its potential to stimulate hair growth. In this article, we’ll delve into the science behind MK-677 and explore whether it lives up to the hype as a hair growth supplement.

Understanding Hair Growth

Before we discuss the role of MK-677, it’s essential to understand the basics of hair growth. Human hair goes through a natural growth cycle, consisting of three phases:

Anagen phase: This is the active growth phase where hair follicles produce new hair. It can last for several years.

Catagen phase: In this transitional phase, hair growth slows down, and the hair follicles shrink.

Telogen phase: The resting phase, during which hair is no longer growing, and it can eventually fall out.

Hair loss can occur when the anagen phase shortens, leading to thinning hair or baldness. The reasons for hair loss are diverse and can be genetic, hormonal, or due to lifestyle factors.

What Is MK-677?

MK-677, also known as Ibutamoren, is a growth hormone secretagogue. It stimulates the secretion of growth hormone (GH) and insulin-like growth factor 1 (IGF-1) in the body. Unlike traditional growth hormone therapy, which requires injections, MK-677 comes in the form of an oral supplement. It has gained attention not only for its potential in muscle growth and fat loss but also for its effects on hair growth.

The Connection Between Growth Hormone and Hair Growth

Growth hormone is vital for various physiological processes in the body, including tissue repair and regeneration. One of the tissues affected by GH is hair follicles. IGF-1, which is stimulated by GH, plays a crucial role in the regulation of hair follicle development and maintenance.

Hair follicles are highly sensitive to hormonal changes. Androgens, such as dihydrotestosterone (DHT), are known to contribute to hair loss in genetically predisposed individuals. IGF-1 can counteract the effects of androgens, promoting hair growth.

MK-677 and Hair Growth: The Science

The potential link between MK-677 and hair growth primarily revolves around its ability to increase GH and IGF-1 levels. By stimulating the production of these growth factors, MK-677 may promote hair follicle activity and extend the anagen phase. Here’s how it works:

Increased IGF-1: MK-677’s ability to raise IGF-1 levels can potentially stimulate hair follicles and encourage new hair growth.

Anti-inflammatory effects: MK-677 has been shown to have anti-inflammatory properties, which can help reduce inflammation in the scalp, a common factor in hair loss.

Enhanced blood flow: Some users report improved blood circulation while using MK-677, which can nourish hair follicles and promote their health.

Telogen to Anagen shift: MK-677 may extend the anagen phase and shift hair follicles from the resting phase (telogen) to the growth phase (anagen), leading to thicker, healthier hair.

User Experiences and Anecdotal Evidence

Many individuals have reported improvements in hair growth while taking MK-677, emphasizing that their hair became thicker, shinier, and stronger. However, it’s important to note that these accounts are largely anecdotal, and individual experiences can vary significantly. Scientific studies specifically focused on MK-677’s effects on hair growth are limited.

Potential Side Effects and Risks

While MK-677 may offer potential benefits for hair growth, it’s crucial to consider the potential side effects and risks. Like any supplement or medication, MK-677 can have adverse effects, including increased appetite, water retention, and changes in insulin sensitivity. Long-term use and high doses may pose health risks, and it’s essential to consult a healthcare professional before starting any new supplement regimen.


The potential of MK-677 as a hair growth supplement is a topic of increasing interest among those struggling with hair loss. While the science behind its effects on hair growth is promising, it’s essential to approach it with caution, considering both the potential benefits and risks. Before incorporating MK-677 into your hair care routine, consult a healthcare professional to ensure it’s a safe and suitable option for you. In the quest for a fuller head of hair, the journey should be one of informed choices and realistic expectations.
