Take your haircare regime to the next level with Kérastase Blond Absolu Ciacanuit, a beautiful lightweight overnight serum that restores blonde hair. Formulated with a high concentration of hyaluronic acid and infused with precious edelweiss, this powerful serum works while you sleep to strengthen and hydrate sensitised bleached hair fibre, visibly reducing the appearance of split ends and leaving you with stronger, softer and shinier blonde hair.

To use: Apply a hazelnut sized amount on washed and towel-dried hair. Apply through mid-lengths and ends, avoiding roots to ensure lightweight volume. Leave in overnight.

Today, more than ever, the world needs care – responsible and sustainable care.

Since 2013, Kérastase has resolved to extend its expertise in the art of care by committing to using less virgin plastic. Drawing on their excellence in innovation, finding new ways to cut down on waste and empower their customers to make more sustainable choices.
Kérastase is committed to optimising packaging whenever possible, using less virgin materials and more recycled materials, recyclable packaging and refillable delivery systems. Beginning with shampoo bottles and branching out to more and more products, they are creating a sustainable packaging program, with many more refill innovations to follow.


Kérastase is also committed to more sustainable production and since 2019 their factory in Burgos, Spain has achieved carbon neutrality by improving energy efficiency and using 100% renewable energy. Since 2017 the Burgos production facility has also been a 'waterloop' factory. This means that 100% of the water used for production processes is recycled and reused in a closed loop. The External water network is only used in the composition of the products or for employee's day to day needs.
