You can see that my model's ears are quite small and very close to the head, so this is the point when you'll see that tiny bit of clipping. The tied down hair clips a tiny bit with the ears, if the ears are very close to the head.
The tied up hair mesh doesn't clip at all, unless your sim's body size is a lot over the middle part of the scale. You can choose from two CASP files: one enables the hairs ONLY for men, and the other makes them still show up for women as well in addition for men.
These hair styles are now enabled for teen to elder men.
Sometimes that marvellous long, flowy hair gets in the way of your samurai sim's furious katana swielding, soldier's epic ride to battle or whatever super manly stuff your dudes might be doing, it's just never a good time to have hair flying all over your face! So tie that mane up, and enjoy your newly found freedom in order to be the alpha-man you need to be! And since pony tails are for ponies, ya gotta tame your mane by tying it up or down.
