Hair loss has always been a common condition, affecting people of all ages and genders. However, there are a few factors that may be contributing to the perception that hair loss is becoming more common nowadays.

Firstly, as our society becomes more aware of health and wellness issues, people are becoming more vocal about their experiences with hair loss. 

Social media platforms and online communities allow individuals to share their stories and connect with others who are experiencing similar issues. This increased visibility may make it seem like hair loss is more common than it actually is.

Secondly, changes in lifestyle and environmental factors may also be contributing to hair loss. For example, stress, poor nutrition, and exposure to environmental toxins can all contribute to hair loss. 

As our modern lifestyles become increasingly fast-paced and stressful, and our exposure to toxins and pollutants continues to rise, it's possible that these factors are contributing to an increase in hair loss cases.

Thirdly, advances in medical technology and the availability of hair loss treatments may also be contributing to the perception that hair loss is becoming more common. More people may be seeking treatment for their hair loss, and therefore, more cases are being diagnosed and treated.

Overall, while it's possible that changes in lifestyle and environmental factors may be contributing to an increase in hair loss cases, it's important to note that hair loss has always been a common condition. 

In the current climate, around two thirds of men (66 percent), and around half of women (50 percent), experience some form of hair loss by the age of 40. This is not much different to how it was 25+ years ago. The majority of men and women have always experienced hair loss by middle age. 

The good thing is, there are now more treatment options that ever before, which means hair loss can be reduced, and even stopped. This leads to more men and women holding onto their hair for a much longer period of time. 

So, based on that theory, we should see considerably less cases of hair loss in men and women, by the age of 40, in the coming years. 

If you're experiencing hair loss, it's important to speak with a healthcare provider to determine the underlying cause and develop an appropriate treatment plan.
