Why haven't my nails recovered?

[Corolla]

I'd worn acrylics for about 6 or 7 years until lockdown hit last March. I knew my own nails would be in a terrible state, but here we are, nearly a year later, and they're still terrible! Things I've done:

Used hand cream and solar oil religiously
Tried nail strengtheners (opi, Sally Hansen, Boots own)
I take biotin and calcium supplements (but I've been doing this for years anyway)
I take iron and magnesium supplements
I drink half a pint at least of milk a day.

They're very short (because they don't seem to be growing), and weak and flakey.

Help!

I've not had acrylics for over a decade and my nails are still awful.

Mine aren't particularly damaged, just a tiny bit of peeling on a couple of them after I was too lazy to go and get my nail polish remover and peeled the polish off instead, but I've bought this as thought it would be good to make them a bit stronger anyway, might be worth a go?

Thanks for the link @StrawberryLipstickStateOfMind, that product looks as if it's good. How long have you been using it for?

My nails are terrible due to so much hand sanitizer, they're all peeling which is very unusual. So I've tried the Essie repair stuff and Nail Envy to no avail. For the last week I've massaged almond oil into my cuticles every night & there's a marked difference.

@Corolla I've been using it for about a week and I think they're a little better but it's probably too early to really say- I'm a bit crap at remembering to use it too! I thought I'd give it a go though because I cba to do the nail polish type strengtheners all the time as quite often prefer not to wear polish. It has really good reviews though!

Try adding a zinc supplement.

The only thing that works is time and never ever getting acrylics again. I have the same problem with gel nails. 6 months it takes me to regrow my entire nail. I suspect yours is slower.

Evening primrose oil is an idea and using the cnd nail oil every day at least twice a day. I also use nail envy by opi but it wasn't so good as I think taking it off weakens my nails again. You cant leave it on it goes yellow.

Thanks all, I've ordered the cnd oil.

@ZenNudist yes I found the same with the nail envy.
