Lord Rama used to apply ash and wear a rudraksha

रामः ससहजो नित्यं पार्थिवं समपूजयत् |

भस्मरुद्राक्षधारी च विरजो योगमास्थितः || 38 ||

 

Lord Rama, along with his brothers, worshipped a clay idol (of Lord Shiva) daily, who used to apply ash (Vibhuti), wear a rudraksha seed, and was without attachments/desires, established in Yoga (means of achieving union with God).

These are typical characteristics of Shaivites.
