What is this?
I have fine, straight hair prone to split ends because it's color-treated. I've tried this a few times in damp hair and once dry my hair becomes a dried up frizzy mess? It does not make it soft or smooth, it quite literally feels dirty and gritty. It honestly feels like a joke. Returning asap

The Best Leave-In Conditioner I've Ever Used
This is hands down the best leave-in conditioner I have ever used, and I've tried quite a few over the years. It leaves my hair feeling incredibly soft, smooth, and manageable without weighing it down or making it feel greasy. I noticed a difference after the first use—my hair was easier to detangle, looked healthier, and had much less frizz. A little goes a long way, and the results last throughout the day. After trying several different products, I've finally found one that delivers exactly what it promises. I will definitely be purchasing this again.
