Hair Loss in Men: Kérastase's Expert Guide to Understand & Prevent

About 70% of men experience hair fall, which can be a real concern. This article reveals what causes men's hair thinning and a loss of hair volume. Below we reveal the reasons we lose our hair and what is the best hair loss treatment for men.

Hair thinning in men can occur for plenty of different reasons, both external and internal. But for many this question still remains unanswered: what causes hair thinning in men? Below we give you the reasons for hair loss.

What is the hair fall process?

According to experts, it is normal to lose anywhere from 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 it is known as excessive hair loss. To understand hair loss better, let’s take a look at the science and what the hair growth process looks like.

Diagnose of hair fall causes

What is the life cycle of a hair follicle?

1. The Anagen Phase: The birth of new hair and the ensuing growth, this accounts for around 85-90% of your hair.
2. The Catagen Phase: The hair stops growing after the anagen phase.
3. The Telogen Effluvium Phase: A period of time in which the follicle shrinks and the hair falls out.
4. The Exogen Phase: A period of 'rest' that makes way for new hair to grow from within the follicle.

Hair fall occurs when the Exogen phase is longer than usual and more hair follicles are shrinking.

When it comes to the appearance of hair thickness, especially at the crown and hairline, hair loss isn't the only issue. In men, hair thinning also occurs when the hair fiber can actually become thinner, over time the hair strands lose volume and become finer which makes styling your hair a difficult and, quite frankly, frustrating task.

How to spot hair loss?

There are many ways to spot that you're losing hair and the 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, it may be that you're losing your hair.

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

For a long time, it felt like an inevitability for many men, but today men's hair loss can be slowed down and prevented. Our Genesis Homme collection is infused with hair growth ingredients like creatine, ginger root, and aminexil (a powerful alternative to minoxidil) to fortify the hair root and helps to slow the hair fall.

How can lifestyle cause hair loss & hair thinning in men?

Beyond genetics and hormones, many moments throughout life can trigger men’s hair loss and lack of much-wanted hair volume.

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

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

How do you prevent & disguise men's hair loss?

Hair loss isn't only about genes and external factors, it’s about the hair care routine too!

Our Genesis Homme collection has a dual anti-fall action benefit—a set of hair thickening products formulated to instantly create the appearance of thicker, denser hair, whilst working overtime to give you long-term results.
