Kérastase

Nutritive 8H Magic Night Serum

Verdict

Kérastase's 8-Hour Magic Night Serum is designed for damaged, especially bleached hair — apply several pumps from mid-lengths to ends before bed. One beauty content creator reports waking up with softer, less frizzy, more manageable hair after consistent nightly use for about two weeks. However, she explicitly states it is not worth it for undamaged hair types, so this is a targeted repair treatment, not a general hydrator.

I truly believe in this product.40:28–40:30
This is a serum that you apply from mid-lengths to ends really saturate those ends.40:34–40:38
If you have bleached hair specifically, that's who I think the 8-hour magic night serum would be the most standout for.41:10–41:24
You will wake up with the softest hair.41:47–41:56
After consistently using it every single night probably around like week two that's when you'll really start noticing the benefits.42:00–42:05
I do a few pumps of this really saturate the ends. I almost like over saturate the ends with the serum and then work just like a little bit through mid lengths and then I seal it in with the oil.42:14–42:26
By the time I wake up the two products have absorbed into my hair and it feels so silky and so smooth. It's way less frizzy. It's way more manageable.42:26–42:37
If your hair type is not damaged I do not think the eight hour magic night serum is worth it.42:48–42:54
