Hey! Recently I did a research about hair. Me personally hate hair, I always had problems with it and still have. But maybe this will be helpful to others too. Just wanted to have this links in one place and share with others, feel free to comment and add yours.
So the most useful info I found is from Zbrush Summit 2016. Official ZBrush Summit 2016 Presentation - Naughty Doghttps://www.youtube.com/watch?v=aHmWZey9r9g
The example and short tutorial is here. But seems very pricey for this one, especially when there is a lot of info for free on youtube.https://gumroad.com/l/pDpQi
(Anyway only author can choose the price so no judging.
This example shows hair workflow using Zbrush https://www.3dartistonline.com/news/2015/04/how-do-i-create-real-time-hair-for-games/
And very good example , but it's with only russian comments.https://www.youtube.com/watch?v=Y2HDZ3VrBdU
This one is Maya workflow with creating hair directly in Maya and Baking all maps with alpha. (Btw you can found for free this model from autor on his gumroad https://gumroad.com/l/jbadG
Another one workflow using 3ds Max Ornatrix , but works nice with other 3ds max modifiers. https://www.youtube.com/watch?v=0OTXkRCmdNE
The hair in this article I bet were made in Maya , but first passes on hair were made just painted by hand. By @future-fiction http://polycount.com/discussion/148038/aigis-fanart#latest

Nice share by Goeddy, he uses fiber mesh as a base to bake maps for the hair. You can go and ask him more questions in his thread. http://polycount.com/discussion/187749/ue4-hair-tutorial-using-fibermesh-and-3ds-max
