“Washing your hair often doesn’t make it fall out”ensures the Professor Leonardo Celleno, President of AIDECO, Italian Association of Dermatology and Cosmetology).

This belief is partly motivated by the fact that when you shampoo, you lose a lot of hair. “It depends on the mechanical action of the clutch and the traction exerted with washing; by rubbing them, the near-falling hair still held in the hair follicle is washed away. They would fall anyway, but certainly in a less evident way “explains the expert.

2. Washing your hair too much makes it even greasier: false

Frequently washing your hair also has an undoubted advantage. “This is the best way to treat scalp seborrhea: it’s not true that washing them often makes them re-fat “explains Professor Celleno.

«Every 72 hours or so the hair re-greasing reaches its peak, coinciding with the maturation of the sebaceous cells that produce it. To avoid trauma to the stemsusing a good conditioner after shampooing, it certainly makes the hair shinier and ready to be properly styled ».

3. Stress, plates and wrong diets increase the fragility of the stems: true

It is true that hair is mostly brittle due to aggressions resulting from external factors. Among the most common, for example, an exaggerated use of plates and other tools for hair at very high temperatures. «For the rest, the fragility of the hair derives above all from alterations in the physiological hair cycle».

“These alterations can produce real alopecia”, continues the expert. “In all these conditions, the hair will weaken, become thin and fall out in greater quantities than normal. Sometimes, too stressful events and exaggerated diets damage the growth cycle, orienting it towards the final phase “.

4. Coloring your hair damages it: Yes and no

Wild styling aside, even the discolorations are potentially harmful to the hair, albeit with the necessary distinctions.

“Treatments for aesthetic purposes can gradually lead to greater fragility of the stems, but also poor hygiene, environmental contamination with consequent accumulation of smog and excessive exposure to the sun have their weight”, adds Professor Celleno.

Any problems, in conclusion, “they cannot be attributed to a single cause such as a tinctureeven if it is undeniable that in the long term poorly thought out colors and aggressive treatments are not good for the hair at all “.

5. Dyes are bad for your health: false

When it comes to colors, however, the doubts are not limited to the possible weakening of the hair: the questions go further. The question often circulates on the Net whether certain treatments may even be carcinogenic.

“Although the dyes are made with very reactive substances, the level of exposure of the individual in the context of a rational and correct use of these products does not seem to constitute a concrete risk of developing related pathologies “, reassure the specialist.

«Furthermore, the possible development of allergic reactions does not represent a connotation of tinctures as“ harmful products ”because an allergy, in itself, is possible for many substances and is linked to the individual genetic predisposition. The safety margin of the individual ingredients used in the dyes, moreover, is such as to make their use safe», Concludes the specialist.

What really matters is contact only competent professionals and avoid doing it yourself, especially in case of problems, which are related to the skin or the stems.
