How often should you wash your hair?

Behind this question often lies a misconception: one should space out shampoos at all costs, even if it means having dirty hair, to "do good" for the hair.

In reality, the goal is never to leave hair dirty for longer. The challenge is to understand what we wash, how we wash it, and with which hair products.

Because these elements - much more than a specific number of washes per week - are what keep hair clean, healthy, and comfortable for longer.

Before talking about washing frequency, the right questions to ask yourself

Rather than immediately seeking an ideal rhythm, it's more appropriate to start with these questions: What condition is my scalp in? What products do I use to wash it? Am I cleaning it without damaging it?

It is this understanding that allows for lasting results, and not an absolute rule on the number of shampoos.

We don't wash hair, we wash the scalp

This is a fundamental point, still too often misunderstood: we wash the scalp, not the lengths. The scalp is living skin. It is what: produces sebum, sweats, reacts to stress, hormones and the environment, can become irritated, itchy, or imbalanced.

The lengths, on the other hand, are dead fibers. They produce neither sebum nor sweat and therefore do not need to be aggressively washed. During a properly executed shampoo, the lather that runs down during rinsing is enough to clean them. Understanding this completely changes the way we think about washing frequency.

The real question: the condition of the scalp

When the roots quickly become greasy, or the scalp itches, feels tight, or becomes uncomfortable, the problem is not with the lengths. It is a scalp imbalance.

Faced with these signs, many adopt counterproductive reflexes: washing with water or dry shampoo more often, using very stripping products to "start from scratch," masking the effects with chemical treatments that coat the hair fiber.

The result: a vicious cycle sets in. The more the scalp is attacked, the more it defends itself. It produces more sebum, the roots become greasy faster, and the need to rewash intensifies.

Chemical products: an illusion of clean hair

Many conventional hair care products rely on a superficial effect: highly cleansing agents for an "immediate clean" feeling, silicones or occlusive ingredients that envelop the fiber, artificial shine that gives the impression that everything is fine.

But beneath this smooth and shiny layer, the hair is not necessarily healthy, and the scalp is not rebalanced. The problem is camouflaged, not treated. This is how you can have hair that seems clean on the first day... but quickly becomes greasy, dull, or uncomfortable on the second day.

Can you space out shampoos in case of imbalance?

When a scalp is already uncomfortable - greasy roots, itching, tight sensations - it is not always possible to immediately space out shampoos.

The goal is not to force a spacing, nor to keep hair dirty to "acclimatize" the scalp. The goal is to gradually rebalance.

This involves: a gentle cleansing base, non-aggressive products and the right techniques for using them, respectful formulas, and an appropriate pH.

The key role of pH and natural products

The scalp and hair naturally thrive in a slightly acidic environment, with a pH between 4.5 and 5.5.

A shampoo formulated within this range allows for: cleansing without stripping, preserving the skin barrier of the scalp, closing the hair cuticles, limiting dehydration and imbalances. With natural, well-formulated products, free of aggressive agents or chemical camouflage, the scalp can gradually regain its balance. When respected, it produces less sebum in response - and hair remains clean, light, and comfortable for longer.

So, how often should you wash your hair?

There is no universal answer. But in an ideal situation, with a healthy scalp and appropriate products, most scalps can be washed once or twice a week.

This rhythm allows for respecting the scalp's natural balance, avoiding excessive sebum production stimulation, and maintaining clean hair for longer.

The frequency also depends on lifestyle. A very active person, who exercises or sweats a lot, will naturally need to wash their scalp more often. Sweat is not dirty in itself, but it can create discomfort and promote the accumulation of impurities. Similarly, certain repeated actions, such as frequently running hands through hair or over-manipulating it, can accelerate hair greasiness.

Spacing out shampoos: a consequence, not a goal

It's important to state clearly again: the goal is never to keep hair dirty to "do it good." The goal is to wash better, to keep hair clean longer. Under these conditions, spacing out shampoos becomes a natural consequence, not an imposed constraint.

In summary

Rather than asking how many times a week to wash your hair, it is more appropriate to ask: What condition is my scalp in? What products do I use to wash it? Am I cleaning it without damaging it?

A healthy and respected scalp allows hair to stay clean, comfortable, and beautiful for longer, naturally.

This is the approach Maison Jearom advocates: to wash better, rather than to wash less - for truly clean and lastingly healthy hair.
