My Favorite Kérastase Products for Shiny, Healthy Hair
If there’s one beauty category I will happily invest in, it’s haircare—and Kérastase is the brand I keep coming back to. Their products just work. Shiny hair? Check. Less frizz? Check. Stronger, healthier strands that look like you get a professional blowout every week? Big check.
These are my top Kérastase favorites that I use on repeat. If you’re looking to upgrade your routine, this is the list.
✨ Nutritive 8H Magic Night Serum (My #1 Favorite!)
If you buy one thing from this blog post, it’s this.
The Nutritive 8H Magic Night Serum is basically beauty sleep for your hair. It hydrates, softens, smooths frizz, and makes your hair feel like silk when you wake up. It’s lightweight, non-greasy, and perfect for dry, dull, or over-styled hair. I use it year-round, especially on nights when my hair needs a little TLC.
Why I love it:
✔ Deep overnight hydration
✔ No greasiness or heavy feel
✔ Makes my hair so shiny the next morning
✔ Smells expensive
✨ Elixir Ultime Hair Oil
A classic for a reason. This is the hair oil that gives that effortless, glossy, model-off-duty finish. You can use it on damp hair, dry hair, or even as a finishing touch on styled hair. It smooths frizz, adds shine, and protects against humidity.
Why I love it:
✔ Makes hair look instantly polished
✔ Lightweight and never greasy
✔ Great for flyaways and frizz control
✨ Genesis Hair Serum
If your hair breaks easily, sheds more than you want, or just feels fragile, this serum is magic. It strengthens the hair fiber, so your strands feel thicker and healthier over time. I apply it to my roots 3–4 times a week.
Why I love it:
✔ Helps reduce breakage
✔ Strengthens fragile roots
✔ Lightweight, non-sticky formula
✔ Great for thinning or stressed-out hair
✨ Gloss Absolu High-Shine Anti-Frizz Shampoo
This is my go-to shampoo when I want glossy, smooth, frizz-free hair. It’s sulfate-free, smells amazing, and makes your hair feel clean without stripping it.
Why I love it:
✔ Adds instant shine
✔ Controls frizz even in humidity
✔ Leaves hair silky, not tangly
✔ Safe for all hair types (and especially great for dry or dull hair)
✨ Gloss Absolu High-Shine Anti-Frizz Conditioner
Pair this with the shampoo and you have the ultimate shine duo. This conditioner makes detangling so easy and leaves my hair insanely soft. It’s the perfect everyday conditioner if you want smooth, glossy results.
Why I love it:
✔ Detangles without weighing down
✔ Boosts shine even more
✔ Anti-frizz benefits that actually last
✔ Leaves hair smooth and hydrated
✨ Genesis Défense Thermique Blow Dry Fluid
This is my heat protectant of choice. It protects up to very high heat, adds softness, and somehow makes my blowouts look smoother and easier. If you use hot tools—or even just blow-dry—this needs to be in your routine.
Why I love it:
✔ Heat protection up to 450°F
✔ Reduces frizz while styling
✔ Lightweight cream texture
✔ Makes blowouts look professionally done
✨ Gloss Absolu Glaze Drops
These are the finishing-touch drops that give your hair that “glass shine” moment. Think of them as jewelry for your hair. One or two drops is all you need to smooth the ends and boost shine.
Why I love it:
✔ High-shine finish
✔ Great for touch-ups
✔ Smells amazing
✔ Anti-frizz benefits without heaviness
✨ Genesis Hair Mask
If your hair needs repair, this is the mask I reach for. It’s super rich, creamy, and leaves my hair feeling strong and moisturized. I use it once a week (or twice if my hair is struggling).
Why I love it:
✔ Strengthens and hydrates
✔ Helps reduce breakage
✔ Adds softness and bounce
✔ Perfect for color-treated, dry, or damaged hair
