I do tip for the holidays - my usual holiday tip for my stylist is the cost of one visit, rounded up. So if you usually pay $15 for the cut + say $5 tip = $20, I would tip $25 being the $20 holiday tip plus regular visit $5 tip. I usually hand over the cash, wish him a happy holiday. No card or gift, just a sincere thank you and a bit of holiday cash to spread around.
