Found out why it does this though👀

In The Sims 4 community, custom content (CC) is essential for personalizing gameplay. Shiny hair CC, while popular, often receives mixed feedback. Many players find that it resembles plastic rather than realistic hair, which can detract from immersion. This has sparked discussions about aesthetic preferences in CC. Players frequently express a desire for more lifelike textures and styles that better reflect diverse looks. Alternatives include matte hair CC and styles that mimic real-life hair characteristics, leading to a richer gameplay experience. When choosing CC, consider the impact on your game's overall visuals and how they align with your style. Engaging with forums such as #sims4, #simscc, or #simscommunity can provide further insights into the best options for your Sims. Always look for creator reviews and community feedback to ensure you're getting high-quality content that enhances your gameplay. By exploring different types of CC, players can find styles that resonate with their vision for their Sims. Whether you prefer the glossy shine or the understated matte look, there’s a wealth of resources in the Sims community to help you achieve your desired aesthetic.
