Silver grey hair, purple shampoo not covering

[IamEarthymama]

I have long covid, it has affected my hair, skin and nails.
I am taking vitamins, trying to eat well and keep hydrated.

My hair is natural gray, pixie cut and I use Fudge purple shampoo to keep a lilac-toned silver gray.
Since I had Covid the Fudge shampoo isn't covering my hair in the same way. There is yellowish tone to some strands of hair, especially in my fringe.

I use a 'normal' shampoo for first wash to cleanse any hair products then leave Fudge n for about 10 minutes. I have tried leaving it for longer, this makes no difference.
I have dead ends of my hair trimmed regularly so I don't think it's dead or very dry hair.
I have bought a hair mask, hair rejuvenating spray and heat protection spray today.
Any other suggestions please? Should I use a Silver gray permanent dye?
Leave it au naturel?

( Spell gray as grey? 😉🦻🏻)

Have you tried Shrine drops? They are drops of temporary dye /toner you mix with a conditioner and apply after washing with a no silicone shampoo. You can adjust the colour by adding more or fewer drops so you could have a play to see if dialling it up a bit works better

Thank you all so much

Shrine had zero effect on my hair.

The OP said she wanted lilac tones.

You can dilute the colour of any direct dye tint with white coloured hair conditioner making it a more of a pastel shade.

Less is more is the mantra to consider.

You should end up with a soft emulsion type consistency although a couple of brands don't mix as well and can be quite drippy. Still works as well but messier to apply.

Ah I misread! Thanks

There’s a Blue Banana near my workplace!

Thinking of venturing in even though I don’t have my granddaughter as cover for aged woman!

only joking, the staff are lovely!

I will report back later. If I have to go on holiday with bright purple hair it’s on MN!

(I am going to Glastonbury, it will be fine☺️)

I really appreciate the information about UV light and the effects, I couldn’t work out what I was doing wrong. I am going to buy some sun protection for my hair today.

I would try not shampooing with a different shampoo and instead do two washes with the fudge each time. It seems to build up the colour better this way.

Well, I bought a Manic Panic Blue Steel from Blue Banana and it has worked really well.
I have packed bandanas and my summer hat for my holiday as the forecast is good.

I thank you all for your support!
