When your body doesn’t get enough Vitamin D, it may slow down or hinder hair production, leading to thinning hair or loss. To combat this, consider increasing your Vitamin D intake through sun exposure, diet (such as fatty fish, dairy, and fortified products), or supplements, after consulting with a healthcare provider.
