Today, this exceptional mask exemplifies the brand’s expertise in luxury haircare.

  1. Elizabeth T Chicheportiche

    This product is truly amazing! It’s so silky and smooth and works on damaged hair. The scent is heavenly! Best masque on the market!

  2. Elizabeth T Chicheportiche

    This masque is amazing! The scent is incredible and makes your hair so silky and smooth. I was living in France for awhile and the water was so hard it really started drying my hair out. This masque brought back moisture and really softened the texture of my hair. If it can work on hair from the hard water in France it can help anyone.

    Hands down the best treatment for my highlighted hair

  4. Jennie Hirsh

    This was amazing! My hair was much smoother and silkier with use. My only regret is that it is not available in a smaller size!

  5. Rose

    Am I using it wrong? How can so many people have good results when it makes my hair feel awful! I use it after I shampoo as a conditioning treatment and leave for 5-15 mins. Wash it out and my hair feels like straw. Perhaps it is a protein like treatment and that’s why? I just don’t get the same silky results as everyone else and it’s upsetting condsiering the $150 price point. I have used other
    brands and experienced better results.

      Hi Rose! The best and most effective way to use this deep conditioning mask is to apply it directly on your dry hair (length & ends) prior to shampooing. Without the water barrier, it will more deeply penetrate the hair follicle, giving dry, damaged hair the nourishment it needs. Leave on for 15-20 minutes (either clip up hair or put on a shower cap), then rinse well and shampoo. You can also use it as you indicate, however, it is best to towel-dry hair after you shampoo, and apply a thick layer of the Masque Quintessence to the length & ends, combing through for even distribution, and rinse well. If you still have questions or concerns please reach out to us directly via LiveChat or at Thank you!

    Leonor Greyl’s Masque Quintessence is the beauty treat of a lifetime! Taking care of yourself from the smile on your face to the health of your hair, this masque does it all!
    Quality product!

  7. Ellen Fleysher

    This is a true miracle product! If your hair is damaged by over-processing, over-drying, over whatever-ing, you need this! Apply to ends first, then hair shaft. I put a shower cap on and leave it on overnight. In the morning, rinse out. You will have a new head of hair. It is that good. Pricey? Yes. But the product lasts a long time and is totally worth it!

  8. Kelly

    Treat yourself. This mask is worth it. Goes a long way. I love it.

  9. amirakhakim

    Nothing special for this price 🙃

  10. Andrea Livoti

    I prefer all the other Lenor Greyl masks to this one. It just didn’t do it for me like the other masks.
