Kim Kardashian has shared her beauty routine on Instagram, featuring the luxury French hair mask Leonor Greyl Masque Quintessence to nourish her color-treated hair.

The American television personality, known for frequent transformations involving hair color, extensions, and heat styling, displayed the French cosmetic product among her personal collection.
The high-end treatment has remained a staple of French hair care for nearly two decades. While the company recently updated the external packaging, the original formula remains identical to the version introduced in 2008.

Origin of the Paris hair treatment
Leonor Greyl created Masque Quintessence in 2008 to rescue hair severely damaged by bleaching, color treatments, and thermal styling tools. Over nearly twenty years, the formula established itself as a signature treatment for the French brand.
The development of the product originated at the Leonor Greyl Institute in Paris. Salon professionals combined various custom mixtures to find an effective repairing solution for clients suffering from damaged hair.
David Brooks, the Director of Research and Development at Leonor Greyl, took inspiration from those custom salon formulations when creating the retail mask.

Botanical ingredients and formula
The formula relies on three key botanical ingredients designed to restore damaged hair fibers. Organic cupuaçu butter from the Amazon region provides intensive nourishment to dry strands.
Mongongo oil, extracted from the nuts of the African Manketti tree, supplies vitamin E while working to hydrate, regenerate, and restructure damaged hair. Jojoba oil adds protective moisturizing qualities.
Together, the natural plant ingredients act deep within hair fibers that require more intensive repair than a standard conditioner can offer.

Application methods for damaged hair
The treatment offers flexible application options depending on individual hair type and level of damage. While users can apply it after shampooing as a deep conditioner, Leonor Greyl recommends a pre-wash routine for fine hair.
Applying the mask to dry hair from mid-lengths to ends for 20 minutes before shampooing provides intensive nourishment without weighing down fine hair. The formula is safe for dyed or highlighted hair because it does not strip color.
For routine maintenance, users can apply the mask once or twice a week. Severely damaged hair may benefit from more frequent use until natural elasticity returns.
Users seeking intensive repair can also leave the mask on overnight by applying a small amount to dry hair and washing it out the following morning. The 200 ml product is available for €96.
