Shampoo is your indispensable ally in removing impurities from your hair. Do you know it well? Experts answer the most common questions about this product!
Myth 1: Using dry shampoo will cause hair loss.
the truth: There is no scientific basis for this claim. Dry shampoo contains powders, starches or talc, which absorb fats. None of these substances directly threaten hair growth. However, this does not mean that dry shampoo or any other styling preparation can be left on the hair and scalp for days, as there is a risk of irritation and dandruff formation. When using dry shampoo, avoid rubbing it into the roots of your hair.
Myth 2: Shampoo must have a balanced pH.
the truth: This is very important, which is why all shampoos today are like this. The pH level is usually between a safe 5 and 7. If the pH level of the hair exceeds 10, the hair will swell, which will cause irreparable damage. Coloring procedures and chemical hair treatments affect the increase in pH, however, shampoos have not been able to do this for decades due to strict quality control.
Myth #3: If it’s good for your skin, it’s good for your hair.
the truth: Vitamins, hyaluronic acid, natural oils… All these ingredients, whether in skin care products or shampoos, are very effective. However, this is only in theory. Although hyaluronic acid has been shown to hydrate the skin, it has not been scientifically proven to have the same effect on the hair. In addition, shampoo does not remain in the hair, but is washed off, which is why the active, useful substances do not remain on the scalp.
Myth 4: Not using shampoo is healthier.
the truth: Shampooing removes some of the natural oils that nourish your hair. However, oil isn’t the only thing that accumulates on your scalp every day. Skin all over your body is constantly scaly, which is why dead cells, bacteria, fungi, excess fat, and pollutants from the environment settle on the surface of your scalp. If this residue remains for more than a few days, it may cause irritation, itching, or dandruff. (New research shows that dirt particles in the environment are particularly irritating.) In addition, some hair products—foams, gels, varnishes—can cause skin irritation due to their ingredients. If you don’t wash your hair and scalp regularly, your hair will become harder and more prone to breakage when you comb it. The bottom line: Washing your hair is a must, and it’s perfectly fine to wash it every day. If you experience itchiness, a tight scalp, eczema, or dandruff, wash your hair once a week.
Myth 5: Sulfate-free shampoo is a better choice for color-treated hair.
the truth: If you often dye your hair, you probably know that it is recommended to use a sulfate-free shampoo to avoid color stripping. However, research has not yet proven this assumption to be completely correct. After all, as incredible as it sounds, water can also damage your hair, just like all other methods of removing impurities from your hair. When your hair is wet, it swells, the cuticle opens up, and some dyes can be washed out. Some studies have shown that sulfates can irritate the eyes and skin. However, the fact that a certain shampoo is sulfate-free does not necessarily mean that it will not irritate a sensitive scalp. Other ingredients, such as foaming agents, can cause skin irritation. If you have a sensitive scalp, choose a shampoo that contains the substances “isosulfates,” “taurates,” or “decyl glucoside.” Avoid substances that contain C14-16 olefin sulfonates. The last-listed substances are often included in sulfate-free shampoos and have been shown to be just as strong as any sulfate.
