Product Overview

Sebastian Professional Penetraitt Overnight Repair Serum is a concentrated leave-in treatment designed to restore vitality to dry, damaged hair. Formulated with hyaluronic acid and niacinamide, this serum works while you sleep to replenish moisture, strengthen strands, and improve overall hair health. The lightweight, non-greasy formula absorbs quickly without weighing hair down, leaving it soft, smooth, and manageable by morning.

Key Features and Benefits

  • Hyaluronic Acid: Attracts and retains moisture, helping to hydrate dry hair and reduce brittleness.
  • Niacinamide (Vitamin B3): Strengthens the hair shaft, improves elasticity, and adds shine.
  • Overnight Repair: While you rest, the serum works to repair damage, reduce split ends, and prevent breakage.
  • Lightweight Formula: Non-greasy and fast-absorbing, suitable for all hair types without leaving residue.
  • Convenient Leave-In: No rinse needed, perfect for busy mornings.

How to Use

Apply a small amount to clean, towel-dried hair before bedtime. Focus on mid-lengths and ends, especially if hair is dry or damaged. Comb through to distribute evenly. Do not rinse. Sleep with the serum in for overnight repair. In the morning, style as usual. For best results, use consistently as part of your nightly hair care routine.

Who It Is For

This serum is ideal for anyone with dry, damaged, or chemically treated hair. It is also great for those seeking a simple overnight treatment to improve hair moisture and strength without extra effort. Suitable for all hair types including straight, wavy, curly, and coily textures.

Why Choose This Product

Sebastian Professional is a trusted brand in salon-quality hair care. This serum combines advanced ingredients like hyaluronic acid and niacinamide to deliver visible results. Unlike heavy masks or oils, this lightweight serum won't leave your pillowcase greasy or cause buildup. It's a hassle-free way to wake up to healthier-looking hair every day.
