Our modern lifestyle exposes us to a multitude of factors that can wreak havoc on our hair health:

These factors are nearly impossible to avoid completely in our modern world, making almost everyone vulnerable to hair issues at some point in their lives.

In recent years, there has been a noticeable surge in the use of hair care supplements.

More individuals are exploring hair supplements as a complementary approach to traditional hair care methods, seeking comprehensive solutions for maintaining healthy, vibrant hair.

What Can Be Done About It?

How Genetics Contribute To Hair Loss

While environmental factors play a significant role, genetics also contribute to hair loss and thinning.

Twin studies have identified heredity as accounting for around 80% of the predisposition to baldness [1].

This means that even with a perfect lifestyle, many individuals will still experience hair problems due to their genetic makeup.

According to the American Hair Loss Association, by age 35, around 66% of American men will experience some degree of noticeable hair loss. By age 50, approximately 85% of men will have significantly thinning hair. But it's not just men. Women constitute around 40% of American hair loss sufferers.

Stress: The demands of work, relationships, and daily life can take a toll on our bodies, including our hair.

Which Hair Supplements Actually Work?

While individual results may vary, there is growing evidence supporting the effectiveness of well-formulated hair supplements. Studies in recent years suggest that, when combined with a healthy lifestyle, certain vitamins and minerals in the right proportions can help to regain what was lost.*[2]

According to expert dermatologist Rod Sinclair, MBBS and senior scientist Nick Rufaut, PhD, biotin deficiency can cause hair loss.. Deficiencies of other vitamins such as vitamin A or zinc may similarly cause hair loss.

In today's world, hair loss and thinning are becoming increasingly common problems that affect both men and women.

Many people turn to over-the-counter supplements or topical treatments for hair loss, but these often provide disappointing results. Here's why:

Insufficient dosages: Many generic supplements don't contain effective amounts of key nutrients.
Poor absorption: Some nutrients are difficult for the body to absorb, rendering them ineffective.
Lack of comprehensive approach: Hair health requires a combination of vitamins, minerals, and other compounds that work synergistically.
Topical treatments only address surface issues: They fail to nourish hair follicles from within.
One-size-fits-all formulas: These don't account for individual needs or the complexity of hair growth cycles.
