The sensation of dirty hair can stem from a subtle misunderstanding.
In summer, the scalp works harder: understanding this means preparing it for cleansing, not simply washing it more often.

There are judgements we make in a matter of seconds.

Weighty roots? Oily scalp.

Loss of volume in the hair? Too much sebum.

Hair that gets greasy straight away? You need a more effective shampoo. 

These associations are so automatic that they seem like the only possible ones. Yet, especially during the summer, they may only tell part of the story.

When temperatures rise, in fact, the scalp’s behaviour changes too. And that hair that already looks as though it needs washing might not be the result of a greasier scalp, but of a scalp that is simply working harder.

Are we sure it’s all down to an oily scalp?

 

Two very different processes coexist on the scalp: sebum protects the skin and hair, contributing to their natural balance. Sweat, on the other hand, allows the body to dissipate heat and regulate its temperature. 

During the summer, it is mainly sweating from the scalp that increases, fuelled by the heat, physical activity, the wearing of hats or helmets, and temperature fluctuations between air-conditioned environments and the open air. 

These are two distinct phenomena that we often tend to confuse.

  

Sweat does not make hair dirty; it changes the behaviour of the scalp

 

Let’s dispel a long-standing myth: sweat, in itself, does not make hair dirty.

However, it can alter the scalp’s microenvironment and influence how we perceive our hair. When sweating is heavy, it can carry some of the sebum down the length of the hair shaft. The roots lose volume, the lengths become weighed down, and the style tends to last for a shorter time.

It feels as though your hair needs washing, even when sebum production hasn’t actually increased.

 

A small but significant revelation: in summer, the scalp works harder

 

Think of the scalp as living tissue: it reacts to heat, humidity, the sun, salt and the constant changes in its surrounding environment.

Rather than becoming unbalanced, during the summer it faces a season in which its activity intensifies.

Rhythms change.

Needs change.

And the feeling of freshness we experience between washes changes too.

Perhaps, then, we shouldn’t just be asking ourselves how to wash our hair.

The right question – the one we should start asking ourselves – is how to support the scalp through this natural adjustment.

Spoiler: the solution isn’t to wash it more often

 

It’s probably happened to you too…

When your hair looks dirty, your first instinct is to wash it more often. It’s understandable.

But if the signal is coming from the scalp, perhaps the answer isn’t simply to wash more often.

Let’s think about it carefully: just as we use specific treatments for our facial skin when the seasons change, the scalp can also benefit from a routine designed to support it precisely during the periods when it’s working hardest. 

There is, in fact, a stage that is usually overlooked, and that is the one just before washing. The key to the ‘problem’ lies there: it is at that underestimated moment (that very one) that we should start paying attention.

 

The (often forgotten) ritual for the scalp

 

When we imagine a haircare routine, we almost always think of shampoo and a hair mask, or conditioner.

Yet there are essential treatments that are applied before washing, with the aim of supporting the scalp at times when it is subjected to greater thermal stress and intense sweating.

Hydro-balance scalp gel was created precisely for this purpose.

Applied directly to the scalp before the hair bath and left on for around 15–20 minutes, it helps to promote a pleasant sensation of comfort and freshness, helping to keep hair light, full-bodied and clean for longer. Its formulation is also designed to counteract the effects associated with changes in lactic acid levels that can accompany excessive sweating. 

In a nutshell? It is not a substitute for the hair bath best suited to your specific needs.

It prepares your hair for that stage.

This summer, the truly revolutionary step won’t be leaving your hair unwashed for one more day. It will be learning to listen to your scalp with greater – and deeper – attention.
