Nails splitting vertically - help.

Mine were like that’s it’s taken years to heal my vertically split thumb nail. I’ve been taking collegen supplement for 6mths and being diligent with my nail strengthener Miracle Cure nail strengthener, the splits have grown out now but I still have the ridges. So good improvement but I think the ridges are just an aging thing so I’ve not much hope of getting rid of them.
I think the collagen has improved both nails and hair thinning but some people see no improvement.

Personally, I up my egg consumption[it is the gelatine I think] for a nail problem.
Someone medical I know, she eats jelly[raw I think]
.

Hope that helps.
