Introduction to Nail Health

Have you noticed white spots at the base of your nails? If so, it's essential to understand why they appear, as ignoring them could lead to concerns later.

What Causes White Spots on Nails?

Many individuals observe white marks on their nails, particularly at the point where they grow. You might have these spots too, but do you know their origin? These marks are known as leukonychia, a common condition. If the white marks are at the nail's base, it's referred to as 'true leukonychia.' Conversely, if the spots are found beneath the skin of the nail, it's termed 'apparent leukonychia,' and if they appear on the nail surface, it's called 'pseudoleukonychia.'

Reasons Behind Leukonychia

You may be curious about what triggers leukonychia. One possible cause is an allergic reaction to products used on the nails, which can lead to these spots. Additionally, trauma to the nails can also result in their formation. In some cases, fungal infections may cause white spots on the nails. Furthermore, certain medications can have side effects that manifest as these marks.
