Hair is lifeless appendage, but one of our most eye-catching features. They contribute a lot to the personal appearance and are often seen as a figurehead of our condition. It is therefore understandable that damage to the scalp or loss of splendor can affect the well-being of many affected people.
How fast do hair grow?
Hair is formally only dead matter - an appendage of the skin that is formed in the hair roots and eventually horny. The flexible and tension-resistant horn filaments are embedded in the hair follicle, at the end of which new hair cells are produced. These push the old hair cells upwards by about 0.30 millimeters per day. The outer layer of hair is similar to a pine cone and consists of various interlocking scales, which are interconnected.
The hair growth in humans runs in different cycles, that is, some hair grow while others are just in the resting phase. Various factors such as age, season and hormone levels also play a major role.
Causes of hair damage
Although dead and largely unnecessary - for many people, hair is considered a symbol of beauty. But numerous influences can damage the hair. This is especially noticeable in the summer. If hair is attacked from the outside, for example by intense UV radiation, the scales move.
The result: they no longer reflect the light evenly in one direction, but to different sides. As a result, the shine is lost, the hair looks brittle and dull. If it badly affected, it is even fragile.
Not only the sun, but also chlorine from the swimming pool attacks the hair structure, making it dull and rough. Bleached hair may even turn greenish by a chemical reaction when it comes into contact with chlorine. Even salt water sets the hair. The salt crystals reflect the light, enhance the sun's effect and thus the risk of hair damage. In addition, hot blow drying also increases the hair's appearance and makes it dry and brittle.
Outer "hair enemies" at a glance:
- Mechanical effects: intensive combing, brushing or teasing, tight tying back, above all always in the same place
- Chemical effects: Tinting, dyeing, bleaching, perming, frequent washing with alkaline shampoos, bathing in chlorine or salt water
- Physical influences: sun or UV radiation, excessive heat caused by hair dryer
False or one-sided eating habits can affect the hair, as well as acute and chronic diseases.
