If you use custom hair and wear a helmet, you may see the lack of hair from below of the head and neck. I suggest to cover the neck on these helmets(Ancient Nord) by chainmail, cloth, leather or something else. This may be as a replacement or as standalone (standalone is better than replacement, because it is better to have and the male version of Ancient Nord Helmet for female characters) I use ApachiiSkyHair by Apachii http://www.nexusmods.com/skyrim/mods/10168/? Yes i know Apachii create pack of vanilla helmets with hair that cover up the neck, but it's little not that what I need I apologize if this idea has already been announced and rejected... And thank you for your attention.
