Some women are lucky enough to be born with naturally long strong nails (genetics, good diet, good health?) while others can’t grow their nails to save themselves.
Nails can be in various conditions; thick and white, see through and bendy, flaky and brittle. Cuticles can show signs of damage such as hang nails and hard skin around the nail area. Nails might have nail wrinkles (lines) running up them (a sign more moisturisation is needed).
One way of getting longer stronger nails is to actually pay them attention. Might sound odd and yet it makes sense. Neglected body parts tend to look neglected, whereas well looked after body parts tend to be in good condition.
Start by paying attention to your nails daily.
