How to Use

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.

Available Sizes & Shades

FAQs

Q: Can I use both products on coloured or chemically-treated hair?

A: Yes. Both formulas are designed to be gentle and suitable for hair that’s been dyed or chemically treated. As always, patch-test if you have very sensitive scalp.

Q: Do I need to rinse the night serum in the morning?

A: It depends on your hair type and sleep routine. For heavier hair types you might rinse; for finer hair you can style over it. Follow your usual nightly routine.

Q: How often should I use the oil and serum?

A: The oil can be used daily before styling as needed. The night serum can be used nightly or several times a week depending on your hair’s condition. Adjust to your hair’s needs.

Q: Will this set replace my shampoo/conditioner?

A: No. These treatments are designed to complement your existing shampoo-conditioner routine—not replace them. Use them on top of your regular cleansing system.
