Alterna Caviar Anti-Aging Replenishing Moisture Overnight Serum 3.4 oz — Lightweight Leave-In Hydration & Heat Protection

Alterna Caviar Anti-Aging Replenishing Moisture Overnight Serum is a lightweight, leave-in night serum that deeply hydrates and replenishes dry, brittle hair while you sleep without staining pillows.

Designed as a nightly ritual, this non-greasy serum absorbs into mid-lengths and ends to restore moisture, reduce the look of breakage, and add humidity resistance. Formulated with Alterna’s Age Control Complex, Marine Moisture Complex, hyaluronic acid and ceramides, it nourishes strands and provides heat protection up to 450°F so hair is ready for styling in the morning. Use on towel-dried or dry hair—no rinsing required.

How does this serum work overnight to improve dry hair?

The formula delivers sustained hydration by infusing moisture reservoirs and strengthening the hair’s surface while you sleep. Lightweight emollients and humectants lock in hydration without weighing hair down, so strands feel softer and appear more supple by morning.

• Hyaluronic acid attracts and retains moisture within the fiber.
• Ceramides help rebuild and reinforce hair structure.
• Marine Moisture Complex supplies restoring minerals and antioxidant support.

Will it stain pillows or leave hair greasy by morning?

No—this pillow-safe serum is formulated to absorb cleanly without leaving oiliness or transfer on bedding. The lightweight texture focuses on mid-lengths and ends, so it hydrates where hair needs it most while keeping roots fresh.

• Non-staining formula tested for pillow transfer resistance.
• Use 1–2 pumps for shoulder-length hair; apply mid-lengths to ends.
• Add more product only on extra-dry or coarse ends to avoid buildup.

How does it protect hair from heat and humidity?

The serum includes shielding ingredients that provide thermal protection up to 450°F and help reduce the effects of high humidity. This dual action means hair is better defended during morning styling and stays smoother in humid conditions.

• Thermal shield minimizes damage during blow-drying and hot tools.
• Humidity resistance helps hair maintain shape and reduce frizz for up to 72 hours in high-humidity tests.
• Improved manageability speeds up styling time and enhances styling results.

How should I use it for best results?

Apply the serum to towel-dried or dry hair before bed and distribute evenly through mid-lengths to ends. Start with one to two pumps—add more only where hair is especially dry—and style as usual in the morning without rinsing.

• For fine hair, use a smaller amount and focus on ends to avoid weighing hair down.
• For very dry or textured hair, increase application to mid-lengths and ends for deeper replenishment.
• Compatible with color-treated, chemically processed, and heat-styled hair.

Who is this for: Alterna Caviar Anti-Aging Replenishing Moisture Overnight Serum suits anyone with dry, brittle, or heat-stressed hair seeking a restorative, leave-in night treatment.

If you want a simple evening step that improves texture, protects during styling, and keeps pillows clean, this serum is an accessible nightly addition to your haircare ritual.
