Users rave about its moisturizing properties, making it a good choice for those with dry or damaged hair. The ability to use it daily is also a plus, as it doesn’t compromise on cleansing while promoting healthier hair. However, it’s important to note that individual results can vary, meaning that while some may see improvements in hair thickness and health, others may not experience significant changes. Additionally, while the natural earthy scent may be favored by some, it might not appeal to everyone.
