I didn't realize I liked putting food in hair until my wife now. I would put mayonnaise in her hair for conditioning purposes at first. I have also done pudding, whipped cream, butter and recently shaving cream. My wife's hair is waist length. I think what makes it interesting is these things don't normally go in hair. I won't do anything sticky. This always leads to washing her hair which is another thing I love doing. I have an amazing wife that lets me enjoy my hair fetish in many ways.
