KEUNE Keratin Smooth 2-Phase Leave-In Spray 6.8 oz — Smoothing, Strengthening, Lightweight Finish

KEUNE Care Keratin Smooth 2-Phase Spray is a lightweight leave-in conditioner that smooths, detangles and reinforces damaged hair using keratin plus Silsoft technology.

This two-phase spray blends protein and conditioning actives in a low-pH formula to help rebalance moisture, calm the cuticle and add shine without weighing hair down. Shake the bottle to mix the phases, mist onto damp or dry hair, finger-comb or brush through, then style as usual. The spray targets frizz and porosity while leaving strands soft, more manageable and ready for heat styling or air-drying.

How does this spray help when my hair feels dry or brittle?

The Keratin-enriched formula delivers protein where hair needs reinforcement, while the Silsoft component helps smooth the surface of the cuticle. Together they support elasticity and reduce roughness so hair behaves more predictably during styling. The low pH helps the cuticle lie flatter, which improves shine and combability.

• Keratin infusion to strengthen weakened fiber and reduce breakage risk.
• Silsoft technology to seal the cuticle and balance moisture levels.
• Low-pH formulation for smoother, shinier-looking hair.
• Lightweight finish that won’t weigh down fine to medium hair.

Can I use it on both damp and dry hair, and what’s the best application?

Yes — the product was formulated for versatile use on damp or dry hair. Shake well to combine both phases, spray evenly through lengths and ends, then rake through with fingers or a wide-tooth comb. Use a small extra mist on stubborn tangles or frizz-prone sections before blow-drying or air-drying.

• Shake to mix phases, then spray 6–8 inches from hair for even coverage.
• Apply to damp hair for easier detangling and faster styling.
• Refresh dry hair with a light mist to tame flyaways and add shine.
• No rinse required — style immediately after application.

Will this product work with colored or chemically treated hair?

The gentle, low-pH formulation is compatible with colored and chemically treated hair, helping maintain vibrancy by smoothing the cuticle and reducing friction. Keratin supports structural integrity while the conditioning phase helps control moisture migration that can dull color. It’s a salon-friendly finishing step to improve manageability after color, relaxers or lightening services.

• Safe for use on color-processed and chemically treated hair.
• Helps the cuticle lie flat to preserve color reflection and shine.
• Supports strand resilience after professional services.
• Lightweight formula avoids buildup that can mute color intensity.

How does it perform in humid conditions or for frizz control?

Silsoft technology works to repel excess moisture from the hair surface, reducing the cuticle lifting that leads to frizz in humidity. By improving moisture balance and smoothing the strand surface, the spray helps hair stay sleeker for longer. For stubborn humidity, pair with a styling serum or light hold product for extended control.

• Silsoft helps lock out ambient moisture that causes frizz and puffiness.
• Smoothing effect reduces flyaways and improves comb-through times.
• Use before heat styling to create a sleeker foundation.
• Works well layered under lightweight serums or creams for extra hold.

Who is this for: KEUNE Care Keratin Smooth 2-Phase Spray suits anyone with damaged, porous or frizz-prone hair looking for a quick leave-in treatment to detangle, strengthen and boost shine. It’s especially useful for people with color- or chemically-treated hair, those who use heat tools regularly, or anyone seeking a lightweight smoothing step that won’t weigh hair down. Ideal for home use or as a finishing touch after salon services.
