• This Duo includes 15 mL (0.5 oz) of the Elixir Ultime Hydrating Hair Oil and 30 mL (1.0 oz) of the Nutritive 8H Magic Night Serum.  

 

Suggested Usage:

Step 1 – Daytime: Elixir Ultime Hydrating Hair Oil

• Apply to towel-dried hair (or dry hair) before styling.

• Dispense a small amount into palms, rub together, and distribute evenly through mid-lengths and ends.

• Style as usual—this oil boosts shine and helps tame frizz.

Step 2 – Nighttime: Nutritive 8H Magic Night Serum

• Before going to bed, apply a quarter-sized amount onto dry or slightly damp lengths and ends.

• Comb through gently. Leave overnight to allow the serum to work during your sleep cycle.

• In the morning, rinse if desired (check your routine) or simply style as usual.

Incorporating both gives a full 24-hour care cycle: protective oil during the day + restorative serum at night.
