Simply apply several drops of Kerastase Cristalliste Serum Lumiere after drying my hair, and it smooths and makes my hair look healthier and softer. Would definitely recommend it!

I like this Kerastase Cristalliste Serum Lumiere,, mostly because of the perfect tender smell. It's a pleasure to use it but if you have dry long hair it's better to choose some other Kerastase oil.

Kerastase Cristalliste Serum Lumiere 50ml smells divine and makes my hair really shiny and soft, without weighing it down. Bottle is small but since you don't need a lot I think I'll get plenty of use out of this!

I have been hooked to Keratase range for many years since Nutritive, perhaps the first range of Keratase as far as I know. For reference, I have good hair condition, fine long black hair although with regular perm and dye. I don't need Keratase to maintain my hair condition actually. This Cristalle Serum does the job as promised. I use it after curl reviving creme in the morning. This serum is a good final touch to giving shine and seem to give more bouncing to curls too.

Kerastase Cristalliste Serum Lumiere 50ml is a great product for dry hair. Just 3-4 drops on clean hair and it gives perfect shine. I love it.
