Longest arm hair (female)
Sarah Hetrich
13,566 centimetre(s)
United States (Woodbury)

The longest arm hair (female) is 13.57 cm (5.34 in), and was achieved by Sarah Hetrich (USA), in Woodbury, Minnesota, USA, on 27 September 2021.

Since she was a child looking through the Guinness World Record books she received as Christmas gifts from family, Sarah always wanted to achieve a record title.

After noticing an extremely long hair on her left arm, she did her best to preserve it for two years, until it reached its maximum length, and the fun-loving and awesome staff at her dentist's office could take the official measurement.
