Nails splitting vertically - help.

I have crumbling nails for years and also an underactive thyroid.

I have tried so many remedies which haven’t worked. However I recently bought some Mavala (Mava Strong) £11 for a small bottle but surprisingly my nails have started to grow. Give it a go kitty hope it works for you. 👋

I have spent so much money on my nails in the past and they never improve.

Mine split , but not vertically They just splitting at the top.
They have been like that for years.
I do my own manicure and pedicure…
my nails have always been weak.
I will not recommend any products because I don’t think they work.
I buff them and paint with clear nail hardener.

Quite a few of my nails split length ways, about two months ago I saw recommended online a treatment called OPI repair mode, which you paint on twice a day then once a day, it’s a clear non shiny liquid. I’ve done this and my nails have definitely improved now being in the best shape for many years and not splitting, I now paint it on about once every two days. I was hesitant as it was about £20 and I’m not one for
spending but this seems to have been worth it. Time will tell.

My nails were splitting vertically and flaking. Turned out I was anaemic. GP prescribed iron tablets but they make me constipated so I've been using Better You Iron 10mg from Amazon. My haemoglobin is now in the normal range and ferritin going on the right direction. My nails have improved no end. No splits.

The only thing that works for me is BIAB gel nails. But they're worth it to me to avoid the splitting.

My nails were a mess until I starting taking Biotin. It takes months but it does work.

My nails were dry and peeling with vertical lines. I think washing up liquid was the cause of the dryness. I have been using Healthy Hoof cream for about 3 months now. My nails are no longer dry and have a healthy sheen. The vertical lines have gone as well. I think it was from Amazon or eBay.

My finger nails are terrible, vertical ridges which often split at the top. I have a pretty healthy diet and take vitamin and mineral supplements but nothing seems to help really.
I'll give healthy hoof cream a try!

My nails are a very good stress indicator and one has been splitting vertically for a few months - the others have just been dry and splitting at the edges. I’ve just been keeping it very very short and filing the catchy bits, and rub olive oil in (to all my nails) every day. I also have started taking a very good over 50s multi vitamin. There’s a definite improvement but the gradual removal of the stress must also be helping (parental death/IHT/probate etc).
