Air India is facing criticism over new grooming guidelines for its cabin crew that were published in the Indian media.
The strict rules include five pages dedicated to hairstyles alone, while other sections dictate strict guidelines for what staff are allowed to wear in hotels.
What are the new rules?
All cabin crew have been told to regularly dye gray hair, according to a document published by Indian broadcaster NDTV.
It is mandatory for crew with "frizzy hair" to undergo hair smoothing or relaxing treatments.
"Wavy, curly and frizzy hair cannot be left open," the guidelines state, adding: "Bushy, unruly and unbecoming hairstyles are not permitted."
Bangs on the forehead and side bangs are also banned. Hair pieces and wigs can only be worn if there is a "medical reason" and if they receive written permission from the airline.
"Crew with a very big forehead or scanty hairline should style the front hair with a side sweep and must cover the receding hairline," the guidelines instruct.
Men with bald spots or receding hairlines are also instructed to "keep a full bald look."
"Head must be shaved daily for a clean look. Crew cut is not permitted," the handbook reads, according to NDTV. Beards are also banned except for Sikh cabin crew.
Nose piercings are not permitted. Certain types of religious jewelry are also not allowed.
"Wedding choora, religious threads, black threads, beads on wrist, ankles and forearms are not permitted," the guidebook reads.
Cabin crew who are on leave, but traveling with Air India are also barred from wearing short skirts, "hot pants" and torn jeans.
The new guidelines sparked debates online, with some users criticizing the rules as sexist and ageist. Others objected to the curbs on religious jewelry.
News agency ANI, citing unnamed Air India sources, defended the new rules as necessary to compete on the international stage.
"Air India is the only airline in the country which has been serving the world for many decades. Representations and images of the crew are not as per international standards. The new management wants to change the perception of flyers," one of the airline sources was quoted as saying by ANI.
