Scientific Hair Facts: Discover the Secrets of Your Hair

How much do you really know about your hair? Today we invite you to test yourself with some scientific curiosities about hair that will help you discover many aspects that perhaps you did not know. Whether they are numbers, statistics, physiological characteristics or even historical curiosities, knowing more about the structure and life cycle of our hair is the first step to taking care of it in the best possible way. If you are passionate about hair care or if you simply want to expand your knowledge, continue reading!

The Average Lifespan of Hair: How Long Does It Last and How Does It Grow?

One of the most interesting scientific curiosities about hair is its longevity. Men's hair lasts from 2 to 4 years, while in women , this duration extends on average from 5 to 6 years. Each hair follicle goes through different regrowth cycles: when a hair falls out, the follicle is already ready to grow a new hair. The life cycle of hair is divided into two main phases:

  • ANAGEN PHASE : is the active growth phase of the hair. During this phase, which lasts on average from 3 to 6 years, the hair grows rapidly. Factors such as nutrition, blood flow to the scalp, and psychophysical and hormonal balance play a fundamental role in promoting healthy and vigorous hair growth. Adopting a balanced diet, rich in essential nutrients, can strengthen the health of the hair. In addition, the use of specific hair supplements, especially during transition periods such as seasonal changes, can help keep them strong.

  • TELOGEN PHASE : is the resting phase in which the hair follicle becomes inactive. During this phase, which lasts from 2 to 4 months, the hair remains anchored to the scalp, ready to be replaced by a new hair that will begin to grow at the end of the Telogen phase. Hair loss in this phase is physiological and completely natural.

Hair Elasticity: A Test to Measure It

The structure of hair is extremely elastic, which means that it can deform and then return to its original shape when subjected to chemical or physical forces, such as the heat of a straightener.

You can do a simple test at home to check the elasticity of your hair: take a wet hair from different areas of the head, hold it still at the base with one hand and gently pull it outwards with the other.

If the hair grows without breaking and returns to its original length, it has good elasticity. If, however, it breaks easily or does not return to its original length, it may have reduced elasticity, a sign that it needs more care and attention.

Most Widespread Hair in the World: A Statistical Curiosity

Statistically, the most common hair color in the world is black . However, blonde hair is present in only 2% of the world's population, while red hair is the rarest natural color of all.

These data refer exclusively to natural hair colors and do not take into account the infinite transformations made possible by modern chemical colorations, which not only change the color, but also offer treatments that protect and nourish the scalp and hair themselves.


Longer Hair: A Fascinating Phenomenon

Hair, when wet, can increase in length by up to 30% compared to its dry length. This phenomenon is particularly evident in curly hair, which, due to its structure, tends to appear shorter when dry.

In fact, some hairdressers, to better evaluate the fall of the locks and the distribution of the volumes, recommend cutting with dry hair, precisely to obtain a more precise.

Knowing the scientific and physiological mechanisms that govern hair growth, structure and health is essential to taking care of it in the best possible way.

From the length of the hair’s life cycle to the strength and elasticity of the hair, every aspect plays a crucial role in maintaining a healthy and vigorous mane.

Furthermore, the discovery of the links between evolution and hair genetics opens up new scenarios for hair care in the future.

Adopting sustainable daily care practices, such as a balanced diet, the use of targeted supplements and gentle hair treatment, can help preserve their beauty and health over time.
