Nail Grooves / Depressions

The condition renders to the changes in the nail matrix and nail bed, which can be damaged or affected chemically, biologically or mechanically. Whilst slight vertical nail grooves / depressions on the nail are normal and highlight the ridges of the nail bed, there are certain things to look out for which may indicate the nail is suffering from a condition. When vertical grooves / depressions appear more prominently this could be a sign of ageing or could indicate the client has a health condition such as dermatitis, eczema, anaemia, vitamin or nutritional deficiency. Nail delamination, dryness and colour changes could accompany the condition.

Horizontal depressions can be Beau’s lines that may indicate a serious medical condition, including anaemia, cardiovascular and thyroid conditions, syphilis or diabetes. Some medical treatments can also cause this condition e.g. chemotherapy. Nail salons using dangerous practices, such as an e-file manicure or an aggresive cuticle removal can be a cause due to traumatisation of the lunula area. They can also be caused by a swelling of the PNF either due to inflamation or an allergic reaction.
