Also if you brush only the top of the tail with a soft brush only that stimulates hair growth. Coconut oil stimulates thickness and workes
Never brush your horses tail!!
Yeah. Wash it often and use conditioner and leave in conditioner. And you can also find specific products that'll help with hair growth. If the tail is banged it looks fuller and then it won't be pulled out as Gwen said.
Keep banging it. It will keep getting thicker if u won't let it. It to the ground they will start stepping on it and pull it out.
