When it comes to healthy-looking hair, the right serum can make all the difference — but choosing the right formula matters just as much as using one at all. At ACTIIV, our hair serums are intentionally formulated to support different hair types, textures, and needs — because not all hair thrives on the same approach.
Here’s how to know which ACTIIV Hair Serum is right for you.
ACTIIV Water-Based Thickening Hair Serum
Lightweight support for scalp health & fuller-looking hair
ACTIIV’s Water-Based Thickening Hair Serum is designed to deliver targeted, plant-powered actives directly to the scalp without weight or residue. Its lightweight texture absorbs quickly, making it ideal for daily use and for hair types that prefer a clean, barely-there feel.
Best For
-
Fine, thinning, or fragile hair
-
Straight to loosely wavy hair types
-
Oily or combination scalps
-
Anyone focused on scalp support and thicker-looking hair
Why It Works
-
Water-first formula: Allows fast absorption and easy layering
-
Scalp-focused: Helps support a healthy scalp environment
-
Non-greasy feel: Won’t weigh hair down or affect styling
-
Clean, plant-based actives: Designed for consistent use
💡 ACTIIV Pro Tip: Apply directly to the scalp on clean, damp or dry hair. This serum is ideal as a daily treatment or as part of a long-term thickening routine.
ACTIIV Oil-Based Thickening Serum for Textured Hair
Rich nourishment created specifically for textured hair types
ACTIIV’s Oil-Based Hair Serum is intentionally formulated for textured hair — including curly, coily, kinky, and tightly waved patterns. Textured hair naturally needs more moisture and protection, and this serum delivers exactly that through a blend of plant-derived oils.
Best For
-
Curly, coily, kinky, and textured hair
-
Dry, moisture-depleted strands
-
Frizz control and curl definition
-
Protective styles and moisture sealing
Why It Works
-
Oil-based formula: Helps seal moisture into textured hair
-
Plant-derived oils: Support softness, elasticity, and shine
-
Slip & manageability: Aids detangling and reduces breakage
-
Curl-enhancing finish: Adds definition without stiffness
💡 ACTIIV Pro Tip: Apply to damp hair after a water-based product to help lock in hydration. Can also be used on dry hair to refresh curls or smooth ends.

Can You Use Both ACTIIV Serums?
Yes — if your hair routine calls for it.
Some individuals benefit from:
-
Water-based serum on the scalp for lightweight support
-
Oil-based serum through mid-lengths and ends for moisture and protection
This approach allows you to treat the scalp and hair fiber according to their unique needs — without compromise. If your scalp needs lightweight hydration without buildup, our water based scalp serum is the formula to reach for.
