You asked about sculpting each hair individually (I know you were kidding, but I can tell you how to do it). It's best to do hair in sections and then detail them. The best way to do that and get great movement is to sculpt from the END of the hair toward the scalp. That way you don't get lost in the masses of hair.
For examples of human hair done in sections and then detailed, see Frederick Hart's work. Here's a page full of his work: https://tinyurl.com/ya9awdxh
The horse pictured in my bronze above was named Anton (he died at age 25, last year). He was best known for his hair and for passing the thickness, waviness and length on to his get (babies). (By the way, that's not the right reason to choose a particular stallion to breed to your mare - he was also well-built, but most people couldn't see past his hair.) His mane was 4 1/2 feet long and his forelock was 3 1/2 feet long. When he was led, the owner led the stallion while his wife carried his mane so it didn't drag the ground. When he wasn't being shown, it was kept up in braids.
In the photo I was given to use as the model for the sculpture, his mane had formed kind of a circular swirl on his hip. Trying to get that and his forelock to look right was a LOT of work.
Each leg being in a different stage of flight means the feathers on each leg were in a different position. For instance, the hind leg that has landed on the ground has the hair "splashing" up, while the front legs moving forward through the air have the hair more flattened against the hoof, depending on where they are in the stride.
By sculpting from the ends to the beginning of the hair in each section, you can add a lot of movement, show the direction the wind is blowing, show tracks where he's just run his fingers through his hair, etc.
I know you're molding him now, I'm just sharing this for you to consider with your next sculpture. Keep up the good work!
For those who wonder about such things, the sculpture of Anton is 21" L x 7 7/8" W x 16" H.
