Care Routine for Dehydrated Hair

Understanding the origin of dehydration is the first step toward a soothing and restorative hair routine.

Why does the hair fiber become dehydrated ?

The hair fiber can be naturally dehydrated or become so after repeated and aggressive treatments, such as coloring or frequent straightening. It then becomes more porous: it absorbs water very quickly, dries with difficulty, and is more prone to static electricity.

Dehydrated hair can be recognized by its dull appearance and rough texture. More fragile, it also tends to break more easily.

Dehydration results from a hydrolipid imbalance, not from a lack of nutrition.

In other words, dehydrated hair lacks water, while dry hair lacks lipids. This confusion is common, yet hair needs and responses differ.

Prolonged sun exposure, insufficient water intake, environmental aggressors: all are factors that can lead to scalp dehydration. The scalp feels tight, itchy… and hair becomes dull, rough, and lacks hold.

How should you care for dehydrated hair ?

Hydrate the scalp without weighing it down

It all starts with gentle, targeted actions.

Hydrating the hair fiber begins with brushing. Indeed, boar bristles have a structure very similar to that of our own hair. Naturally rich in keratin, they help improve elasticity, strength, and protection of the hair fiber.

But their benefits do not stop there: they ensure gentle detangling and promote even distribution of sebum from roots to ends. After brushing, hair is visibly more nourished, more soothed, and regains shine and vitality.

Brushing is an essential step in any hair routine. To fully enjoy the benefits of your hairbrush, opt for prolonged brushing on dry hair, always starting at the ends before moving up toward the roots.

By smoothing the cuticle, brushing also helps tighten the hair scales, which better preserves hydration and limits evaporation.

The ideal choice? A hairbrush suited to sensitive scalps, such as a boar bristle hairbrush. Boar bristles help distribute sebum from roots to ends, preventing buildup at the roots while protecting lengths. A simple, almost ancestral gesture.

Stimulate microcirculation

To promote nutrient transport, it is ideal to stimulate blood circulation in the scalp. In addition to the boar bristle hairbrush, use the vegan N.04 hairbrush. Made of nylon fibers, it allows for a scalp massage suited even to the most sensitive scalps, thereby stimulating blood circulation.

Another essential habit to preserve the beauty of your hair: ensure proper daily hydration.

Like the rest of your body, the hair fiber depends on water intake to remain supple and healthy. Adequate hydration helps support blood circulation in the scalp, allowing essential nutrients to reach the hair and maintain vitality.

Knowing that hair is largely composed of water, drinking regularly helps maintain stronger, more supple, and better-hydrated hair, from roots to ends.
