Those nails can cause many problems. Find a good dermatologist & or even a good foot doctor too for your toe nails if need be thats experienced in our conditions. To get you started.
From lack of or changes in the nails, I've found keeping my nails short, clean, & buffed.
Buffed by using washable nail buffers, extra fine nail files. Eliminates any roughness & soothes by gently erasing any chips etc. Smooth the nail of roughness or even the skin around it. I prefer to do this dry & gently. Wash hads, gently buff, wash again & apply the best oil or creams that works best for you. I've found it's better to gently buff or file down than try to actually cut the nails of my hands. Cutting can make my hand nails weak, or peal, etc.
And some folks apply creams or oils to their hands & feet before bed & wear gloves & socks to sleep.
If salon appointments are more your style, then go. I have, but l bring my own equipment. I've seen too many misfortunes of what can go wrong even it the finest & best & the cleanest salons.
I hope this helps.

Crossing myself.. no to nails here. I actually get gel manicures and it may or may not be helping— but my nails (knock on wood) have been fine for 15+ Years during this nuisance of a disease.

I can’t either I’m thinking of seeing a podiatrist the dermatologist hasn’t helped much with it

Ahh, reading @A MyPsoriasisTeam Member ‘s excellent response I forgot to mention that my nails seemed very weak when I was first diagnosed. I’d gone through a year if misdiagnoses and my condition had gotten worse and worse. That’s when my nails were bad. As I started treating my skin and making nutritional changes I improved and so did my nails.

The only thing I ever did to my nails themselves ( other than buff and keep them short was to dig up this nail strengthening cream someone had given me years ago. They still make it.. because.. it WORKS great. It was apparently come up with by some people who groomed horses and used some concoction to condition their hooves. The people who applied this realized it was making their nails very strong and a new product was born.

I don’t suppose they’d still make this decades later if it didn’t work. I buy it from Jeff Bezos but it’s also sold by Bed Bath and Beyond.. Walmart… etc. It’s called Barielle Nail Strengthener, you put it on clean unpolished nails. Says you can apply over polish but I think that’s bunk. That’d be like trying to get moisturizer through auto enamel.. um, Nope.

Not saying this will cure nail Pso, but it’s certainly helped me keep mine in better nick.
