1. Gisou ($88) vs. Kérastase Elixir Ultime ($58) vs. Moroccanoil ($48): Which Luxury Bottle Wins?

All three prestige hair oils pair refractive smoothing silicones (Dimethicone / Dimethiconol) with botanical triglycerides, giving you instant cuticle slip and light reflection without raw cooking-oil heaviness. Gisou Honey Infused Hair Oil ($88) adds natural Mirsalehi honey (a humectant) alongside sweet almond and coconut oils, making it the richest option for thick, dry ends.

Kérastase Elixir Ultime ($58) uses lighter French camellia and marula oils for weightless French-salon fragrance and glass shine, while Moroccanoil Treatment ($48) remains the benchmark pre-blow-dry detangler and frizz tamer.

Frequently Asked Questions

Should I apply hair oil to wet or dry hair?

Apply 1–2 drops to damp mid-lengths and ends before blow-drying for heat protection and detangling, then smooth 1 final drop over dry ends to seal flyaways and boost shine.

Does Moroccanoil Original tint platinum blonde hair?

Original Moroccanoil has a warm amber hue from beta-carotene and natural pigments; if you have icy platinum or silver hair, Olaplex No. 7 or Kérastase Elixir Ultime will never alter cool tones.
