Hair you go: Hong Kong start-up HairCoSys uses AI to bring personalised care to the masses
- HairCoSys’ app is able to conduct hair and scalp evaluation with an iPad and a handheld lens through the use of patented AI algorithms
- The start-up receives academic research support through the Hong Kong University of Science and Technology entrepreneur centre and CityU’s Tech 300 programme

A Hong Kong start-up is offering personalised hair care solutions with an artificial intelligence (AI) powered platform that can detect and prevent hair loss.
HairCoSys’ team of data analysts and hair experts have designed an app using proprietary AI algorithms that analyses photos of users’ heads to identify hair and scalp conditions, before suggesting possible ways to treat it.
“The idea for HairCoSys came during the Covid-19 outbreak when I discovered my friend’s hair loss problem after taking selfies over dinner,” said founder and CEO Michael Wong in an interview. “This drove me to come up with the concept.”
HairCoSys’ app is able to conduct hair and scalp evaluation with an iPad and a handheld lens. The technology uses patented algorithms that can calculate the number of hairs and measure the thickness of hair shafts on specific areas of the scalp with microscopic photos.
