The System professional Hydrate Emulsion is a rinse-out mousse treatment that intensely hydrates your hair without weighing it down. Here are the benefits you’ll notice every day:

• Hair feels softer and is easier to comb
• Less frizz and static
• Light mousse absorbs quickly into the hair
• Hair stays light, never greasy or heavy
• Dull hair regains shine and vitality
• Deep-acting hydration that lasts longer
• Suitable for normal to dry and long hair

1. Wash your hair with shampoo and rinse well.
2. Pat your hair dry with a towel so it's damp but not soaking wet.
3. Shake the can well, hold it upside down and spray the mousse onto hair sections.
4. Massage the mousse through your hair from roots to ends.
5. Leave it on for 5 to 10 minutes.
6. Rinse thoroughly with water.

Are you using the System professional Hydrate Shampoo (H1) first? Then you’re preparing your hair for hydration and getting even more from this treatment.

Your hair feels instantly softer and is easier to comb. That’s because the formula contains panthenol, an ingredient that binds water inside the hair fibre and makes your hair temporarily thicker and smoother. Glycerine attracts extra moisture from the air and helps keep it locked in your hair. This gives dry hair exactly what it's missing. The light mousse texture ensures the active ingredients absorb quickly without leaving a greasy layer. Perfect for those with frizzy hair who want light, airy hair. A smart choice for any hair type seeking intense hydration without compromising volume.

The Hydrate Emulsion is best for normal to dry hair, especially long hair that frizzes, gets static, or feels dull and rough. If your hair is damaged from blow-drying, colouring, or sun exposure, you’ll notice the difference after just one use. Hair that tends to get greasy at the roots is less suited to this treatment. The mousse works best when applied to lengths and ends, not directly on the scalp. If you have a sensitive scalp or are sensitive to fragrances, please note the formula contains perfume and fragrance allergens such as Limonene and Hexyl Cinnamal, which can cause reactions in some people.

The Hydrate Emulsion works best as part of a complete routine. Combine it with the System professional Hydrate Conditioner (H2) for daily care and use the emulsion as an extra treatment when your hair feels especially dry or frizzy. Want to go further? The System professional Hydrate Mask (H3) is a richer cream mask you can use weekly for deep care. Use the emulsion less often, about once a month, as an intensive boost to your regular routine.

No. The mousse texture is specially designed to stay light, even after rinsing. Your hair won’t feel heavy or greasy but light and soft. Fine hair that tends to fall flat won’t suffer here, provided you focus the mousse on lengths and ends, not the roots. If you have extremely fine hair that easily gets weighed down by products, a light conditioner as a daily base might be better, with the emulsion as a monthly extra.

Regular hair masks usually have a cream texture and are used weekly. The Hydrate Emulsion is a mousse that absorbs faster and penetrates deeper into the hair fibre. You use it less often, but the hydration is more intense. If you ask how to get the best from System professional Hydrate Emulsion, think of it as a monthly reset for moisture-deprived hair. Alternatives like Kérastase Nutritive Masque Magistral are richer and creamier but also heavier. If you want intense hydration without limp hair, the Hydrate Emulsion is the better choice. For extremely dry or damaged hair that also needs nourishment, a richer mask may sometimes do more.
