OSiS+ Glow Shine Serum for Hair — 1.69 oz Lightweight, Silicone‑Free Anti‑Frizz, Humidity Protection

Formulated with nourishing shea butter, this salon-grade serum from OSiS+ (Schwarzkopf Professional) smooths rough texture, adds reflective gloss and helps hair resist humidity. The non-greasy, light-hold formula works on damp or dry hair, letting you refine styles or finish looks with a soft, touchable shine. It’s designed to integrate easily with other styling products, so you can use it alone for a quick finish or layer it with creams and sprays for extra control.

How quickly will I see frizz reduction and shine?

Results are immediate: a small amount smooths cuticle roughness and reduces visible flyaways right after application. Shine becomes noticeable as the product distributes along the hair shaft, creating reflective surfaces without a heavy residue.

• Apply a pea-sized amount to dry hair for instant polish.
• Use on damp hair before blow-drying for longer-lasting smoothness.
• Targets mid-lengths and ends where frizz and dullness concentrate.

Will this serum weigh my hair down or make it greasy?

No — OSiS+ Glow is formulated to be lightweight and non-greasy. Because it’s silicone‑free and balanced with shea butter, it conditions without creating limpness, keeping movement and volume intact while improving texture and shine.

• Silicone‑free composition for a natural feel.
• Light-hold finish preserves body and bounce.
• Absorbs quickly to avoid oily buildup.

Can I use this in humid weather or on curly hair?

Yes — the serum helps repel humidity’s effect on the hair fiber, reducing frizz and maintaining a sleeker appearance in damp conditions. It’s versatile enough for straight, wavy, curly or coiled textures: use sparingly on finer curls and slightly more on thicker, coarse strands for optimal control.

• Humidity protection to minimize puffy frizz.
• Suitable for all hair types; adjust amount by density and porosity.
• Works as a finishing touch or a curl‑defining boost on wet hair.

How do I incorporate OSiS+ Glow into my styling routine?

Use it as a finishing serum to refine styles or as a conditioning boost during styling. A few drops spread through mid-lengths and ends after drying will smooth and add shine; mixing a drop with other OSiS products enhances smoothness while maintaining hold.

• Apply to damp hair before heat styling to protect and shine.
• Use on dry hair to tame flyaways and add gloss after styling.
• Combine with creams or sprays for layered control and polish.

Who is this for? OSiS+ Glow is ideal for anyone wanting a salon-quality finish without heaviness — people with frizz-prone or dull hair, those living in humid climates, and anyone who wants conditioned shine without silicones. It suits all textures from fine to coarse, and is especially useful for finishing looks, reviving second-day styles, or smoothing ends after heat styling.
