Here's a breakdown:
* Natural Blonde: This encompasses a wide range of shades from very light, almost white-blonde to a medium, golden blonde.
* Ash Blonde: This is a specific *tone* of blonde. It refers to a blonde shade with cool, silver, or gray undertones. It lacks the warm, golden, yellow, or red tones often found in "natural" blonde shades.
While some *specific* ash blonde shades can be darker than *specific* natural blonde shades, the overall understanding is that ash blonde is a *tonal* description, not necessarily a darkness descriptor.
So, to be more precise:
* An ash blonde can be a very light blonde.
* An ash blonde can be a medium blonde.
* A natural blonde can be a very light blonde.
* A natural blonde can be a medium blonde.
The key difference is the *tone* - cool (ash) vs. warm (natural).
It's helpful to compare "ash blonde" to "golden blonde" in this context. Golden blonde describes a blonde shade with warm, yellow undertones, while ash blonde describes a blonde shade with cool, silver/grey undertones.
