I bought this product many times in salons and never had this issue. I put it in the fridge which made the consistency much better. Overall OK after refrigeration. Same impact on hair regardless of consistency. 3/5 stars because of the product texture and consistency without refrigeration. Review: good but too expensive. Might try it again when the price goes down some - This is a very good product but it is very expensive. ## Features - 2 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D9K213VX | | Additional Features | Leave In | | Age Range Description | All | | Age range (description) | All | | Best Sellers Rank | #71,148 in Beauty ( See Top 100 in Beauty ) #692 in Hair Treatment Masks | | Brand | K18 | | Brand Name | K18 | | Customer Reviews | 4.4 out of 5 stars 67 Reviews | | Hair Conditioner Type | Leave-In Hair Conditioner | | Hair Type | All | | Hair type | All | | Item Dimensions | 45 x 45 x 102 millimeters | | Item Form | Mask | | Item form | Mask | | Liquid Volume | 1.7 Fluid Ounces | | Manufacturer | K18 Hair | | Manufacturer Part Number | 1M-N9N8-1GG3 | | Material Features | Natural | | Material features | Natural | | Number of Items | 1 | | Package Type Name | Jar | | Product Benefits | Repairs damage, restores strength, provides smoothness and bounce | | Product benefits | Repairs damage, restores strength, provides smoothness and bounce | | Recommended Uses For Product | damaged/chemically-treated hair | | Size | 50 ml (Pack of 1) | | Special Ingredients | Natural | | UPC | 764544679367 | | Unit Count | 1.7 Milliliters | ## Product Details - **Brand:** K18 - **Hair type:** All - **Item form:** Mask - **Material features:** Natural - **Product benefits:** Repairs damage, restores strength, provides smoothness and bounce ## Images ![Leave-In Molecular Hair Mask 1.7 Fl Oz. - Image 1](https://m.media-amazon.com/images/I/51ffH5aUrpL.jpg) ![Leave-In Molecular Hair Mask 1.7 Fl Oz. - Image 2](https://m.media-amazon.com/images/I/71UbROBeK3L.jpg) ![Leave-In Molecular Hair Mask 1.7 Fl Oz. - Image 3](https://m.media-amazon.com/images/I/71K53cWWbAL.jpg) ![Leave-In Molecular Hair Mask 1.7 Fl Oz. - Image 4](https://m.media-amazon.com/images/I/81an7HwQmLL.jpg) ![Leave-In Molecular Hair Mask 1.7 Fl Oz. - Image 5](https://m.media-amazon.com/images/I/41FJzSIDs1L.jpg) ## Customer Reviews ### ⭐⭐⭐ Overall OK if you ignore the texture and separation issue *by A***A on 31 October 2025* Separated and is in a weird (not what it should be) consistency once pumped.
