Understanding and Preventing Thinning Hair in Men

In men, hair thinning and hair loss can be a real concern. 70% of men experience hair fall. In this article, we reveal what causes hair thinning and a lack of hair volume in men.

Hair thinning in men can occur for many different reasons, both external and internal. But for many this question still remains unanswered: what causes hair thinning in men? Below we reveal the some of the causes of men's hair fall.

What is the hair fall process?

It is normal to lose 50-100 strands of hair per day, we know that sounds like a hefty amount, but it’s only when the number exceeds 100 that is known as excessive hair loss and it becomes a problem. To understand hair fall, let’s take a look at the science and what the hair growth process looks like.

Diagnose of hair fall causes

Each strand of hair goes through a life cycle. It all starts with the birth of new hair and the ensuing growth which is called the anagen phase, this accounts for around 85-90% of your hair.

Next, the hair stops growing and this is known as the catagen phase, which is closely followed by the telogen phase, a period of time in which the follicle shrinks and the hair falls out.

The final dormant phase is a period of ‘rest’ which makes way for new hair to grow from within the follicle.

Hair fall happens when more follicles are shrinking, and the dormant phase is longer than usual. When it comes to the appearance of thinner hair, especially at the crown and hairline, it’s not just hair fall that’s the issue. In men, hair thinning also occurs when the hair fibre becomes thinner, and over time the hair strands lose volume and becomes finer which makes styling hair a difficult and, quite frankly, frustrating endeavour.

How to spot hair fall?

It is possible to spot that you are losing hair in many ways. Most common appears while showering and cleansing hair. It is normal to lose hair, almost 100 every day. But if you spot lots of hair in your hands while showering or styling, this may be a sign that you are losing your hair.

Hair thinning can be also spotted under direct light. In your bathroom, if you can see more and more of your scalp under the spotlight, this may be an indicator that you are losing hair or that your hair is thinning.

For some, hair loss felt inevitable, but today hair fall is something that can be slowed down and prevented. Our Genesis Homme collection is infused with follicle-boosting ingredients like stimulating creatine, ginger root and aminexil (a powerful alternative to minoxidil) to fortify the hair root and helps to reduce hair fall.

What lifestyle factors cause hair fall and hair thinning in men?

Beyond genetics and hormones, there are many moments throughout life that can trigger men’s hair thinning and a lack of much-wanted hair volume.

Work or even exam stress in younger adults can trigger hair fall, as can tiredness from late nights, whether you’re a new father or burning the candle at both ends. And we all know, that when we’re stressed and tired, our diets can suffer - we find ourselves eating on-the-go, forsaking nutrition for convenience. Or we take up bad habits like smoking which is yet another contributing factor to your unwanted hair fall.

Then there are external factors like aggressive chemicals in your shampoo or pollution from city living. All these factors can contribute to hair fall whether that manifests as a receding hairline or thinning at the crown.

How to prevent and disguise hair fall and hair thinning?

Hair loss is not only about genes and external factors, it’s about the hair routine too!
