SINGAPORE — On the first Tuesday of every month, residents at Beo Crescent in Tiong Bahru can be seen shuffling to the void deck of Block 26.

They form a neat queue, take a number, and patiently wait their turn.

Within half an hour, they leave with their hair trimmed, hearts full, and wearing smiles — thanks to Mark Yuen, who is, more often than not, wearing his trademark red beret.

Since 2016, the 69-year-old retired wealth advisor has travelled all over the island to give free haircuts to the elderly and the needy.

Armed with scissors, shavers and combs, Yuen — dubbed "little red hat" by some of his "customers" — provides the service at various places, including nursing homes and senior centres, three or four times a week.

He also does house calls for people who are bedridden or immobile.

"At the end of the haircut, when I see them smile and they say thank you, it rejuvenates me," he said. "Sometimes, the new haircut lets them feel neat and look younger."

More than just a haircut, Yuen's hairdressing sessions are also a way his elderly patrons can socialise.

"Getting the seniors outside of their homes and spending time with other residents and volunteers, I hope it will give them a sense of community care and love...," said Yuen.
