Sensitive Scalp in the City: What the Science Says and How to Care for It Daily

In 10 seconds: Sensitivity isn't just a feeling: it has a biological footprint. Urban life increases inflammation and oxidative stress in sensitive skin. For the scalp, gentle cleansing, barrier support, and reducing the load of metals/particles make a difference in daily comfort.

Why does urban life worsen sensitivity?

Urban environments are associated with greater exposure to particles, metals, stress, and altered sleep rhythms. In sensitive skin, higher biological markers of inflammation and oxidative stress are observed, which helps explain symptoms such as itching, tightness, or burning.

What about the scalp?

It shares mechanisms with facial skin (neuroinflammation, oxidation, and altered barrier) and is also exposed to particle adhesion and hard water metals that can affect scalp comfort and balance, as well as hair fiber shine.

H03: Shine and Vitality Shampoo — ideal for sensitive scalps

H03 Shine and Vitality Shampoo is formulated for frequent washing that respects the scalp barrier and cares for the hair fiber, without fragrance or essential oils.

• Gentle cleansing base: sodium lauroyl methyl isethionate, decyl glucoside, sodium lauroyl sarcosinate, cocamidopropyl betaine, and disodium cocoamphodiacetate → effective cleansing with lower irritating potential.
• Comfort and hydration: betaine and glycerin help with osmoprotection and scalp comfort.
• Shine support and fiber care: olive fruit oil and Cystoseira compressa extract for a shiny appearance and manageability.

Sensitive urban routine in 3 steps

1. Wash gently (daily or every other day). Apply H03 massaging with fingertips. Avoid very hot water.
2. Minimize friction. Towel dry and comb from ends to roots to reduce traction on the follicle.
3. "Anti-stress" habits. Rest, reduce direct heat from the hairdryer, and avoid the accumulation of hard-to-remove styling products.

Who is H03 for?

• Sensitive or reactive scalps who prefer fragrance-free formulas.
• People in urban environments or with hard water (metals, lime) who want to improve scalp comfort and hair appearance.
• Those looking for frequent use without a degreasing sensation and with a shine and vitality effect on the hair fiber.
