A blue-faced nail means you're not getting enough oxygen to your fingertips. This could be linked by respiratory disease, which can mess up the blood vessels in your nails. But it could also mean ...
Onychorrhexis (from the Greek words ὄνυχο- ónycho-, "nail" and ῥῆξις rhexis, "bursting"), is a brittleness with breakage of finger or toenails that may result from hypothyroidism, anemia, anorexia nervosa or bulimia, or after oral retinoid therapy. [1]: 786 It can also be seen in melanoma that involves the nail and onychomycosis. [2]
A new nail plate will form once the cause of the disease is removed. Onychomycosis, also known as tinea unguium, is a contagious infection of the nail caused by the same fungal organisms which cause ringworm of the skin (Trichophyton rubrum or T. mentagrophytes, rarely other trichophyton species or Epidermophyton floccosum [1]).
The nail matrix is the active tissue (or germinal matrix) that generates cells. The cells harden as they move outward from the nail root to the nail plate. [3] The nail matrix is also known as the matrix unguis, keratogenous membrane, or onychostroma. [4] It is the part of the nail bed that is beneath the nail and contains nerves, lymph, and ...
While Beau's lines are actual ridges and indentations in the nail plate, Muehrcke lines are areas of hypopigmentation without palpable ridges; they affect the underlying nail bed, and not the nail itself.

Green nail syndrome occurs rarely in healthy individuals, but can occur in the immunocompromised or those whose hands are frequently immersed in water or who have other nail problems. [5] The elderly and people who have had trauma to a finger or nail are at greater risk of contracting green nail syndrome. [1]
Removed nails are capable of growing back normally over several months if the nail matrix is left intact through surgical extraction. However, if the matrix is damaged by trauma, it can result in an overgrowth of tissue from the proximal nail fold, resulting in the formation of pterygium. Particularly, if the nail matrix is burnt by a heated ...
An ingrown nail, also known as onychocryptosis (from Greek: ὄνυξ (onyx) 'nail' and κρυπτός (kryptos) 'hidden') is a common form of nail disease.It is an often painful condition in which the nail grows so that it cuts into one or both sides of the paronychium or nail bed.
