She was aged 24 years, 282 days when she was confirmed to have a full beard, in Slough, UK, on 7 September 2015. Kaur is originally from Slough, England.

While Kaur has referenced her conversion to Sikhism at age 16 as one of the reasons she stopped removing her facial hair, she now describes herself as spiritual rather than religious.

Traditionally, Sikhism forbids the cutting of hair. She continues to wear her turban or other head coverings, which is a custom of the Khalsa tradition of Sikhism.

To promote self-love and acceptance, Kaur has stated that she has named her beard Sundri, which means beauty or beautiful, and refers to her beard as "she".
