Frizzy Mane?

Is there any way to make the frizz in this mane lie down?
Products?
I know that there's pulling, but I'm afraid that when I pull it, it will still be this poofy/frizzy.

U could try brushing it my shetlands mane is frizzy and it works when we brush it

They are alot of products on the market for that. Show sheen and I think the mane and tail brand did one for frizz. I would try wetting it down and brushing, Also it would work best if you got a spray on detangeler, or mixed some condioner and water in a spray bottle. My Mini's hair was very frizzy, And then I discorvered that under his mane was matted. Also, to help a horses mane lay on the right side and stay down and less frizzy I brand the mane in small sections. Your horse is beautiful besides that.

I brush her mane every time I can and I use showsheen detangler every time. Haha

Brushing can make it frizzy. When I brush Lola's tail it turns into a bush XD So I put Canter Mane & Tail Conditioner in it and the mane. It is really good!

Flat iron?

You could try combing it instead. To me it seems that brushing fluffs and combs help make it lay straight. (my boy's got a poofy forlock and this works for him)
