Before founding Bonita, Ms Uppkar Kaur, one of the parlour's two founders, already had dreams of opening her own salon. For years, customers, who know her as Neeru, had asked and even encouraged her to set out on her own.
When she finally founded Bonita six years ago with the parlour's other owner, Ms Manjeet Kour, they knew it would be difficult, even with the support of loyal customers – customers they saw as close friends, or even family – that they had amassed at their previous workplaces. But their rough start still took them by surprise.
For months, they could hardly breakeven, let alone earn profits. "There was a time when we did not even get a salary," said Ms Uppkar. "We were just surviving with the savings we had. It was that bad."
But before long, business began booming, with each year's revenue rising between 10 and 20 per cent. Last year, the two opened Bonita's other outlet in One Raffles Place.
Beauty parlours like Bonita show the hidden potential within the threading industry. With its low costs and high demand among people interested in grooming their eyebrows, the threading business – although niche – can be profitable too, said Associate Professor Elison Lim of the Nanyang Business School at NTU.
Furthermore, households are spending more and more on personal grooming establishments, like threading shops, according to data collected by the Department of Statistics (Singstat).
According to its latest available data on household expenditure, which was released in 2014, monthly expenditure on these establishments increased by more than twofold to $31.70 on average a month between 2012 and 2013, from $13.10 a decade before. This parallels the sharp increase in total monthly household spending through the years, from $3,351.90 to $4,724.50 in the same time frame.
Likewise, according to data reported by Singstat, revenue from the personal services industry – which threading establishments would fall under if documented, said Prof Lim – has been on a steady upsurge the past two decades, rising by almost threefold to $2.85 billion in 2017, from $0.80 billion in 2000.
This correlates with the development of the economy and economic growth, added Prof Lim.
"With more spending power, people have more money to spend on grooming and managing their appearance," she said. "And our society's definitely becoming more image-conscious."
Nonetheless, Mr Jester Perez, a market research director at a global property development firm who specialises in analysing market trends valuations, said there are still some dangers in investing time and money in a threading business.
