Step-by-Step Guide: How to Use Kerastase Magic Night Serum
Step 1: Preparing Your Hair for Serum Application
- Gather the essentials: You’ll need a bottle of Kerastase Magic Night Serum, a wide-tooth comb or hairbrush, and a towel (optional).
- Start with dry or towel-dried hair: For best results, apply the serum to clean, dry, or slightly damp hair at night before bed.
- Detangle your hair: Use a wide-tooth comb or brush to remove knots. This helps even distribution of the serum.
Step 2: Applying Magic Night Serum – Technique & Dosage
- Dispense the serum: Pump 2-3 doses of Kerastase Magic Night Serum into your palm. Adjust the amount for your hair length and thickness (see the table below).
- Rub hands together: Warm up the product by rubbing your palms together.
- Apply from mid-lengths to ends: Gently work the serum through the mid-lengths and ends of your hair with your fingers. Avoid the scalp to prevent greasiness.
- Optional – Comb through: Use a wide-tooth comb to distribute the serum evenly.
- No rinsing needed: Leave the serum on overnight and let it absorb as you sleep.
| Hair Length | Recommended Pumps |
|---|---|
| Short | 1-2 |
| Medium | 2-3 |
| Long | 3-4 |
Step 3: Nighttime Hair Care Routine with Kerastase
- Optional – Tie your hair loosely: Use a soft scrunchie or braid your hair for less tangling overnight.
- Protect your pillow: The serum absorbs fast, but you can use a silk or satin pillowcase for even better results.
- Leave in until morning: There is no need to rinse the serum out in the morning. Style your hair as usual.
