The Ekos Murumuru Leave-In Conditioner by Natura received mixed reviews from Giana in their video review. Giana mentioned that the conditioner did its job, but it made her straight hair look greasy right after washing. She also found the tube packaging impractical as it became difficult to get the product out towards the end. However, Giana appreciated that the conditioner is clean, with easily understandable and cruelty-free ingredients. She also mentioned that a good amount of product is provided. Overall, the Ekos Murumuru Leave-In Conditioner offers a clean and ethical option for those looking for a leave-in conditioner, but it may not be suitable for those with straight hair due to its greasy effect.
