Kays Hair Extensions - Vanilla is a mod designed for Windows users of Baldur's Gate 3, enhancing character customization through a variety of new hairstyles. The mod separates hair pieces into different slots including Crest, Chin, Jaw, and Tail slots, allowing players to mix and match styles such as ponytails, braids, and bangs. Additionally, these hairstyles are compatible with various character races that fall under the Humanoid, Celestial, Fey, or Fiend tags. The mod also includes accessories that have unique color indicators based on in-game elements.

However, users should be aware of some known issues such as unintended appearances for Dragonborn characters due to compatibility settings, potential clashing physics between different hair types, and color mismatches with base hairstyles caused by texture variations. The mod is free and encourages the use of complementary mods for an enhanced experience, while updates and older versions can be found on the Nexus Mods page.
