Don't be turned away from extensions just because of a two tone tail.
All these companies sell tails for a really great price, and if you send them a picture of your horses tail, and some hair samples, they'll mix a tail for you.
Looks like you'd mainly need all black, with a few extra white hairs mixed in on the top layer..
As far as growth, if her tail has remained this average length, it may be as far as it goes. What you can do though, is keep it moisturized, so the hairs don't break off short, but instead, grow all the way down to it's full length.
I stress over keeping the tail bone clean. That way, they're less likely to scratch and break off new hairs growing in. I'll just take a wet rag, with a little bit of olive oil hair strengthener rubbed in, and run it through the tail.
I'll lightly comb it out with a wide tooth comb, put some coconut oil in, and leave it loose.
I'm not a fan of tail bagging, but if it's a loose one, where the hair can still breath, then it's not too bad.
I personally would use black on her hooves... But that's just me.
I have a bay, so I'm of no help to removing stains.
