A roached mane looks good depending on the horse, really, as others have noted. There is a girl where I ride that used to roach her horse's mane, and it looked absolutely awful. I was so happy when she started growing it out. Then again, I know another girl that has a pony with a roached mane, and I can't imagine seeing that pony any other way. The roached mane just looks perfect on her.
I roach my old gelding havent had any health problems just do it for the fact his mane refuses to pic a side and im not fan of the mohawk he actually looks really good with it roached
I had t o roach rebel cause he decided to get in a fight with a willow bush and the bush won didnt want to but there wasnt really a choice he doesnt look so good roached
I roach my horses manes. Here we call it hogging. I hog because I ride mounted games, and havign to ride one handed/holding something and constantly lengthening/shortening reins the mane gets tangled and can be very dangerous. Also, I show my ASH and it's the accepted look for stock horses. My Arab used to have a mane and it was always thing and straggley, so I hogged it and he looks adorable! He has a mohawk at the moment and it looks so spunky, when it flops I will hog it again.
