Colour of the nailbed and the time it takes to return to original colour after depressing

Yes the nails will be yellow and brittle which is a sign of them being unhealthy

i think as long as they look fairly normal... but no not in depth

The nail beds are white which means your nails are healthy

Would like to know more about how to keep nails healthy

Is it if it’s brittle, yellowish or got white lines

Look out for chipping and coloring and brittleness

Yes I’m definitely lacking in some vitamins lol

Is there an article on the app on this?

Ya shouldn’t be brittle and yellow
