Having grown abnormally inward or back into the skin, causing irritation, redness, and swelling.

Most commonly describes hairs that curl back and re-enter the skin, or toenails that grow into the surrounding flesh.

The story behind the word. A straightforward Germanic compound of 'in' and 'grown', this term has been used since the Middle Ages to describe physical tissues, especially nails and hairs, that deviate from their normal outward growth path.

Word relationships

  • embedded: Embedded means stuck deep within something, whereas ingrown specifically implies that the object grew into its trapped position.

Memory hook

The word itself tells you the problem: the hair has 'GROWN' back 'IN' to the skin. Grown back in.

When not to use

Do not use to describe internal psychological feelings or metaphorical 'deep-seated' habits, where 'ingrained' or 'deep-rooted' is appropriate.

Fun facts

  • People with coarse, curly hair are genetically much more prone to ingrown hairs because the natural spiral shape of the hair shaft naturally coaxes it back toward the skin.
