Hey there! oVertone products are very moisturizing conditioners, which means they're also very thick and can stick around in hair that's not rinsed thoroughly.
To make sure this doesn't happen, you can use warm to mildly-hot water when rinsing out your oVertone conditioner and gently agitate the scalp to loosen up any product that might have dried or thickened on your strands during the waiting period. oVertone actually works better when you use warm/hot water. Your hair should feel soft after it's completely rinsed out, and shouldn't have a slippery soapy feel to it at all.
