The phrase "more snowy-haired" is often used to describe someone with very white or gray hair. However, there are several synonyms that can be used to describe this trait in different ways. One option is to use the phrase "silver-haired," which has a more elegant and sophisticated connotation. Alternatively, you could refer to someone as "white-maned," which emphasizes their age and wisdom. Another possibility is to use the term "frosty-maned," which suggests a sense of strength and resilience. No matter which synonym you choose, it's important to consider the tone and context of your writing, and to choose a descriptor that accurately reflects the character or person you are describing.
