The problem of itchy heads, or rather of itchy scalps, is now more common than ever. Cosmetic dyes, frequent and aggressive washing, as well as smog, irritants and stress are the most frequent causes of irritated skin, dryness and flaking, and of consequential itchiness. HAIRMED ZERO, with extracts of bisabolol, zanthoxylum alatum and almond oil, is a line of treatments for reducing irritation, calming reddening and soothing sensitive scalps. Three products for a complete system. Z1, an oil formula specifically for washing and soothing the skin; Z2, frequent-use cleanser for the delicate washing of the hair; Z3, a soothing anti-itch serum for a rapid and immediate action, even on dry hair.
