The structure of our hair changes with age as well as the structure of the skin. Brittleness, fragility, dull, gray hair … How to overcome these problems, restoring your hair strength and youth?
Many people ask the question – Does your hair grow old in reality or this is just another trick of marketologists who are trying to deliver this idea to us, in order to successfully sell the new product? The various scientific studies confirm the fact that over time our hair does ages, as well as the whole body. But the aging of skin and hair occur in different ways. The facial skin renews itself every 28-30 days. Hair is not programmed to self-renovation, and this means that any damage to the hair will be permanent.

 
If we compare the condition of the hair of 20-year-old girl and 60-year-old woman, the difference in the hair structure will be enormous. With the onset of menopause – on average it occurs after age 45 – the female body starts to produce less estrogen – the hormone that responsible for the lifecycle of skin and hair cells. Hair growth slows down and, thus, the physiological hair loss is not compensated by sufficient growth of the new ones. But it is possible to turn back time, adjusting the proper nutrition.

 

Behind all this: hair dullness, brittleness, slows growth and falling out could be deficiency of the zinc which is found in oysters, strawberries, walnuts. For effective hair growth our body needs building materials – an essential amino acid taurine, which is present in large quantities in seafood, red meat, chicken and turkey. Pollution also negatively affects our hair as well as stress of daily life.
Consumption of antioxidants, green tea or grape seed oil could help to neutralize the harmful effects of stress and improve blood flow to hair follicles. Therefore, if your diet is not rich in these products, you should consider taking supplements containing these ingredients in order to improve the appearance of hair.

 

Proper care

 
All the elements involved in hair growth, also affect aging. The first factors of aging hair can be considered as hormonal status and genetic predisposition, such as if your hair started to turn gray in the 25 years like your mother’s or father’s. The second most important factor is the state of your health in general and the presence of stress.
The quality of daily care also affects the rate of hair aging to a certain extent. Ideally, it includes a thorough but gentle cleansing with shampoo, mandatory conditioning, and the application of nourishing masks at least once a week. Equally important is the proper use of a hair dryer (distance and duration of the direction of hot air to the hair lock), ability to comb hair properly (not to comb or style wet hair).
Japanese scientists have found that over the years the activity of the VEGF gene, which is involved in the mechanism of formation of blood vessels on the surface of the scalp, is falling. From this we may conclude that head massage can help to solve the problem – it will increase blood flow and improve the nutrition of the hair bulbs. So do not forget to thoroughly massage the head at each wash.
As to the products, which claim to be “anti-aging”, they could be used as a preventive measure at any age. But use these products to undergo a treatment course is recommended only when hair or body under great stress.

 
Why does hair turn gray?


Some people experience gray hair by age 25, while some do not find a single gray hair at the age 40. Of course, much depends on heredity, but trichologists believe that if a person leads healthy lifestyle and have good health, then his hair should not turn gray before age 40.
The nervous tension and constant stress make hair turn gray. Inside of our hair is core – thin shaft, through which the liquid circulates. It has been suggested that neuropeptides produced by the body under the action of adrenaline (the level increases during stress), use blood vessels to flow to the hair follicle, and then to the hair shaft and break the chemical bond between the protein and melanin. Then the pigment is washed out very quickly, and as a result, hair loses its color.
Also, gray hair may appear due to certain diseases and dysfunctions, in particular, the hair turns gray with vitamin B12 deficiency or thyroid dysfunction. In addition, smokers have four times higher risk of developing grey hair than nonsmokers.

 
Hair coloring

 
With age, hair becomes less shiny. The explanation is that its outer shell consists of numerous overlapping small scales. When the capillary fiber lacks of internal moisture, these scales raise and do not reflect light well. The easiest way to restore shine and strength is hair coloring.
When the hair is colored, the hair becomes more dense and thick in texture, therefore, more radiant, strong and voluminous. In addition to the saturated pigment, nourish hair with the natural proteins, oils and vitamins, color and gloss restoration is achieved thanks to amino acids. But coloring is stress to the hair, so do it as little as possible by yourself and leave it to professionals!
