Sidakdeep Singh Chahal, a 15-year-old from Uttar Pradesh, India, has set a new world record for having the longest hair among male teenagers, measuring 146 cm (4 ft 9.5 in). Sidak follows a Sikh tradition of not cutting his hair, considering it a divine gift. His family's support has been crucial in his journey. While Sidak's achievement is remarkable, the record for the longest hair on a teenager ever belongs to Nilanshi Patel from India, who cut her hair in 2021 and donated it to a museum.
