    This is a miracle worker. The scent is floral, maybe gardenia-esk. I love it. I have long, highlighted hair and I use this about once a week. It keeps my hair from having fly-always and looking dry/damaged. I comb it through my dry hair, then clip it up and keep it on for as long as I can before I shower it out with just a small bit of Shampooing Crème Moelle De Bambou. I get compliments on my hair often.

    Versatile, very hydrating/ moisturizing and nourishing conditioning treatment for your tresses. It is quite refreshing when I indulge myself with this Gold, in my haircare routine. My hair is relaxed and tamed like fine silk after my indulgement. It’s worth every penny spent. I highly recommend this. Get the feel of Heaven on Earth 🌍.🌹🌹🌹

    Masque Quintessence is a life saver for my curls!! My hair is past my shoulders in length and I don’t need to use much of this product in the shower. The scent is so pleasing, I sometimes will use a bit as a leave in. The softness is beyond words!!

  4. Kim Weiss

    A lifesaver product for me. I use a brush ( the kind stylists use for foils/color)and paint the conditioner on my dry hair. I place a cap and leave it on for as many hours as possible. My hair is so unbelievably soft it’s incredible. It does not feel weighed down. My husband loves it! The smell is very LG. A bit intense at the onset and dissipates into a light fragrance.
    I’m ready to deep dive into the professional size since you can also use this as a mask or instant conditioner.

  5. Victoria

    I’d like to argue that this mask is easy to distribute, and works best on dry hair. If you don’t want to use entire bottle in one time, wet your hair before applying the product.

    This is the mask to use when your hair is constantly under attack from bleach, color and heat. I am using this with Shampoo Reviviscence for over 3 years and tried many other luxury/salon haircare brands. This mask beats everything. It’s very pricey and never something I’d ever imagine spending this much money on but it made my hair so soft and silky, oddly something even the more high tech brands fail to do. It is so worth it and I wish the backbar sizes were in stock year round! One con though is that you have to use it before and after shampooing for the best result, which uses quite a lot of product. I used this when I had virgin hair and had beautiful results, and when I bleached it regularly I almost wanted to try something cheaper but my hair only agreed with this mask and this mask only! I also would like to warn you not to overuse the mask just because it is thin in texture. It is thin but not watered down, it’s a very heavy moisturizing punch. I do suggest Leonor Greyl add some thickeners to really convey how nourishing this mask is and also to give users more control over how much they use. But all in all, I love this. It’s a holy grail product.

    This is the first of many Leonor Greyl products and why I have purchased the rest. I had a head of crispy, damaged hair. After reading the reviews, I put the product on, put on a shower cap and a towel and left the treatment on for quite awhile longer than suggested. I proceeded as suggested and was simply amazed with the results. Every bit of crispness and damage was gone! This is a pricey product, however, if you have damaged hair it is worth every penny! A must have!

  8. Robin Kossman

    I have curly, frizzy hair. My hair is softer. How my hair looks depends on the weather. Masque Quintessence helps keep my hair more consistent.

  9. Lorena Zamudio
