Is it good to wash your hair every day?

We read that over-cleansing your hair can cause dryness and tightness, while under-cleansing can cause irritation and itching from the buildup of oil and dirt. What do we do?

How often should you wash your hair?

At Modesta Cassinello, we recommend washing your hair frequently because it is beneficial for the scalp , and because if done with the right products and the proper washing technique, it is not harmful to the quality of your hair, even if you do it every day.

Why does hair get dirty?

The accumulation of dirt in the hair has multiple origins:

1. Endogenous sources : sebum excretion, which together with the skin's natural exfoliative processes and sweating can lead to irritation processes if not eliminated properly.
2. Exogenous sources : hair treatment products, air pollution and pollen, as well as anything that catches hair on our clothing, when we sit or lie down.

Why can your scalp become irritated if you don't wash it often?

Of the multitude of microorganisms that inhabit our skin, the scalp is home to 25% of the cutaneous microbial population . We can find bacteria, fungi, viruses, and mites on the scalp, although bacteria and fungi generally exist more frequently.

The importance of this microbiome (a community of microorganisms that live in a particular environment) and its balance lies in its impact on the scalp's immune system , which affects the functioning of the follicle and its environment.

The scalp's environment—darkness, sebum, and moisture—make it the perfect environment for imbalance, so a decrease in washing frequency, especially when your scalp is oily, can lead to irritation and dandruff, as well as poorer hair fiber quality.

What happens to the hair fiber, that is, to the hair itself, if it is not washed frequently?

While frequent washing can compromise your hair, the repeated entry of water into the structure causes damage to the cuticle, even the cortex, causing what is known as "hydral fatigue." Not washing leaves hair without volume and even duller, unattractive.

Since hair has positive psychological connotations that allow us to feel more productive, less stressed, and stronger, at Modesta Cassinello, we recommend frequently washing your hair with shampoos with medium-detergency systems and antioxidant, balancing, moisturizing, nourishing, and protective ingredients. These shampoos cleanse and simultaneously protect both endogenous sebum—a natural protection for the hair—and the microbiota present in the hair follicle, which is very important in its entire environment.

At the same time, we recommend alternating washes with shampoos that guarantee a deeper cleansing of the scalp, such as H07 Sea Salt Shampoo . This is especially true when there is excess oil, as this is where the microbiome is disrupted, and hair loss treatments and styling products are also used.

We hope we've been helpful and would be happy to assist you in choosing your ritual for frequent washing of your scalp and hair, and to answer any questions you may have.
