Tayaw kinpun is a traditional shampoo used in Myanmar. Its main ingredients are the bark of the tayaw (Grewia) tree and the soapy kinpun fruit. Lime may also be added to the mix. Shampooing with tayaw kinpun has been an important tradition in Burmese culture since ancient times. Burmese kings used to wash their hair with tayaw kinpun during the royal hair-washing ceremony, in the belief that using the shampoo would cast away bad luck and bring good luck. Today, it is still customary for many Burmese people to wash their heads with tayaw kinpun on the Burmese New Year's Day to leave behind impurities and bad omens of the past.
