I never have before. I generally just use conditioner as a leave-in/styler and have tried to make sure I have one I can use year round...no glycerin or anything like that. I just discovered Giovanni direct leave-in and love it. But, it has aloe listed as something like the 7th ingredient, so I'm paying more attention to the dew points to see if my hair doesn't like it if the dews go too low. I hope not. I like having the same routine/products year round. I hate paying attention to the weather.
If you are having great hair days, then I wouldn't worry about it.
