Oils and Leave-In for Hair

37 products

Dull, frizzy, dry or difficult to manage hair: these are the most common problems that a good hair oil or leave-in treatment without rinsing can concretely solve. The collection brings together 29 products from professional brands — from Alfaparf Milano to Kérastase, from Wella to Silium — designed to nourish, smooth, illuminate and protect every hair type, without weighing it down.

Dry and dull hair: nourishing and restructuring oils

When the hair fiber is dehydrated and lacking vitality, the solution is to replenish the lipid film with oils that have nourishing and restructuring action. Products like argan oil — present in formulations from Volhair, Ekre, Koster and Silium — work in depth to restore softness and lasting shine. The Professional C Cinque mineralizing oil, available in single-dose vials, combines mineralizing salts and panthenol to rehydrate and strengthen treated hair. Kérastase Elixir Ultime and Chronologiste complete this range with oils with a professional profile, ideal for dry and dull hair.

Argan oils: intense nourishment and visible brilliance
Restructuring vials: concentrated treatment for very damaged hair
100% pure castor oil: strengthening of the fiber and scalp
Physiodermric oil: delicate nourishment compatible with frequent use

Frizzy and rebellious hair: leave-in and smoothing oils

Frizz is often caused by lack of hydration or exposure to humidity. The leave-in hair products without rinsing and smoothing oils in this collection act as a protective and disciplining shield. Alfaparf Milano Semi di Lino Smooth Smoothing Oil is formulated with a Climate-Proof complex that tames rebellious hair without weighing it down. The Detangling Primer from the same line improves combability and offers thermal protection up to 230°C, making it essential before using a straightener or blow dryer. Wella Oil Reflections Luminous Smoothing Oil guarantees a silky texture and long-lasting smoothing effect.

Leave-in detangling sprays: immediate combability and frizz reduction
Smoothing oils with light texture: discipline without greasing
Thermal primers: protect during drying and straightening

Curly and wavy hair: definition and humidity protection

Wavy and curly textures require products that define curls without stiffening them and protect against humidity that causes swelling. Alfaparf Milano Semi di Lino Curls Multi Benefit Oil is a multi-action oil that hydrates, detangles, defines and illuminates hair with waves and curls, with a final gloss effect. Liquid crystals — in versions with coconut oil, argan and amla from Silium, and with linseed oil from Professional Hairgenie — add shine and control without weighing down the curl structure.

Hair exposed to the sun and thermal protection

Sun, salt water and chlorine are enemies of the hair fiber. Kérastase Soleil Olio Huile Sirène is a leave-in styling spray designed for hair exposed to the sun, with nourishing and protective action. The Alfaparf Semi di Lino biphasic oil spray combines the practicality of application with complete protection from external agents, also ideal as preparation before hot tools.
