Jumped on the mumsnet bandwagon and applied colour b4. Have been dyeing my hair for years and last time I remembered it was naturally dark brown. Have been going grey for the last twenty plus years (since I was 19). I can't believe how light it is gone!!! The roots are fairly white - not a hint of dark brown anywhere - and the ends are what can only be charitably described as strawberry blond.
Now sat with a dark ash blonde 8 wash semi colour developing. Fingers crossed.
