Kérastase Densifique Sérum Jeunesse: Thickening Hair Serum Spray 100ml

Densifique Sérum Jeunesse is a hair serum treating thinning and greying hair concerns by compensating the loss of hair quality. It protects the melanin of the hair (at the source of natural pigmentation of hair) while this advanced formula helps the hair fibre to regain its initial youthfulness. Hair glows with restored supple softness and volume making it easier to style.

To use: Apply 2-3 doses directly on the scalp section by section. Massage with fingers. Spray 3-4 doses on the lengths and comb to distribute the product equally. Do not rinse. Use the hair drier to activate the treatment. Dosage: 15 doses for short hair, and 20 doses for long hair.

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.
