Natural redhead fading to blonde - restore vibrancy?

(Little long, sorry!)

Hey there, looking for some ideas about what to do with my frustrating hair! I'm a natural strawberry blonde. As i entered my 20s I started "blonding" as many redheads do. It fades and gets more blonde than red.

My hair (in certain streaks and sections) was turning truly white. It runs in my family. Both my father and grandmother (also natural redheads) were totally and completely white by their 30s. Looks like it's just in select parts of my hair at the moment but it's slowly taking over my head, leaving very little that's close to red. Hubby actually said yesterday (when I forced him to closely examine my head lol) that I don't have any red at all anymore. 🙁

It can be tricky dyeing light blonde to red. I would love to get back to my old color, or close, and feel like myself again. Not sure what to try. Pictures are attached.

First collage shows what my natural hair color was most of my teenage and adult life. (Ok these are some awkward faces, try to ignore it!) Second collage: top 2 show how blonde I've been getting (5 yrs ago, it's much lighter now). you can see in the top left a random chunky streak of white.

The bottom of second collage show results of Adore Semi in Ginger mixed with a bit of French Cognac. Love the product, and it's a fun color, but it's nowhere near what I want.

Can I get back to that first color, a deep strawberry I guess it was, or light copper...? What considerations are there when dyeing light blonde and white hair? thanks for any help at all, guidance, resources to check out... *ott*
