Why Does It Take So Long For The Nail To Grow Back?

Nails are made of tissues. Although they are considered to be non-live, they continue to expand or grow. The time length it takes for the nail to grow fully may not be the same for everyone, but it sure takes months to grow back.

There are a few reasons why it takes six months or sometimes more for the nail to grow. The reasons are as follows:

  • The main factor is the natural health of the nail. Nails that are naturally healthy tend to grow at a normal and steady rate. However, when a person has conditions like Nonsyndromic congenital nail disorder 10 or Anonychia congenita, the growth of the nail is substantially affected. If the person has Anonychia congenita, their nails do not grow at all. They do not have nails at all sometimes.
  • The other aspect is anxiety or mental stress that will cause the nail to grow back at a comparatively slow rate. However, if a person has a healthy diet and active life, there are chances that their nails will grow faster or at least at a natural rate.
  • The climate can also determine how fast nails will grow. In summer, nails can grow at a much faster rate as compared to other seasons.
  • A person’s age can also be a deciding factor in the growth of the nails. Younger people will have faster nail growth. Old people have a low growth rate when it comes to nails.
  • A person having Onychophagia will find a faster rate of nail growth. As the person bites the nail more often, it stimulates circulation in the nail.


Apart from the main reasons, even hormones can play a big part in the overall growth of the nail. It is also a fact that the nails on your dominant hand will grow faster than the other hand. The reason behind it is that usage of the dominant hand is more.
