Hair: Fascinating facts about our indispensable hair

Hair is not only an aesthetic element of our appearance, but also carries various facts and information about our health, lifestyle and genetic heritage. 

 

1. Hair structure:

Hair is made up of keratin, a protein substance that also makes up our nails and skin. Each hair is grown from a hair follicle sac located in the scalp. The part visible on the surface is called the hair shaft.

 

2. Hair growth:

The average hair growth for an adult is about 1 to 1.5 centimetres per month. Each hair goes through three growth phases: anagen (growth), catagen (transition phase) and telogen (resting phase, during which hair loss occurs).

 

3. Number of hairs:

The average person has about 100,000 to 150,000 hairs on their head. However, the amount of hair can be affected by genetics, age and lifestyle.

 

4. Hair color:

Hair colour is determined by a pigment called melanin. There are two main types of melanin: eumelanin, which is responsible for dark colour, and pheomelanin, which gives rise to shades from red to blonde.

 

5. Hair loss:

It is normal to lose up to 100 hairs a day. However, excessive hair loss can be a sign of a health problem or a genetic predisposition to baldness.

 

6. Influence of diet and lifestyle:

Hair quality is often influenced by diet and lifestyle. Lack of vitamins and minerals, poor diet and stress can negatively affect hair health.

 

7. Hair as an indicator of history:

Hair can serve as an amazing record of our lives. Analyzing hair can reveal exposure to various substances such as drugs, medications or even heavy metals.

 

8. Symbolism of hair in cultures:

In different cultures, hair has different symbolic meanings. In many societies, hair is associated with beauty, strength and identity.

 

9. Artistic expression:

Hair has always been an inspiration for artists. Artists, writers and musicians often use the symbolism of hair to express emotions, identity and aesthetic concepts.

 

10. Interesting facts about different hair types:

Different ethnic groups have specific hair characteristics. For example, African hair tends to be curlier, while Asian hair is often straight and thick.

Hair is not only an aesthetic element, but also a window into our health and genetic heritage. Their care should be based on an understanding of these facts and each individual's needs.
