Man Bun & Top Knot: Styling Long Hair for Men
There’s something effortlessly cool about a well-tied man bun or a sharp top knot, but pulling it off in Singapore is a different game to pulling it off in a cooler, drier city. Between the humidity, the sweat and the sheer patience it takes to grow the length, plenty of men give up halfway. This is our honest barber’s guide to styling long hair for men here: how much length you actually need, whether to add an undercut, how to tie it so it holds, and how to keep your scalp healthy through the whole journey.
How much length you actually need
Let’s set expectations honestly, because this is where most men underestimate the commitment. A basic top knot or small bun needs hair that’s roughly fifteen centimetres, or around six inches, on top. A fuller, more secure man bun that gathers hair from all around the head wants closer to twenty-five to thirty centimetres. From a short cut, you’re looking at the better part of a year, sometimes more, of growing out.
The tricky bit is the middle. There’s an awkward stage, usually a few months in, where the hair is too long to look tidy short but too short to tie back properly. This is where most men quit. If you can push through it, ideally with a bit of shape from your barber to keep it from turning into a shapeless mop, the payoff is worth it.
The undercut option
One of the smartest decisions you can make is whether to pair your bun with an undercut. This means keeping the back and sides short or faded while only the top grows long. It’s a hugely popular look, and for good reason in our climate.
- It keeps you cooler. Short sides mean far less hair trapping heat and sweat against your neck, which matters a lot here.
- It’s cleaner to tie. With only the top section long, the knot sits neat and high without stray bits escaping around the ears.
- It’s lower commitment to grow. You reach a tie-able top knot faster because you’re only growing one section.
The trade-off is that an undercut needs regular upkeep on the sides, roughly every three to four weeks, and if you ever want to wear your hair fully down, the short sides will look uneven until they catch up. A full-length man bun with all the hair one length is more versatile down, but hotter and slower to grow. Neither is wrong; it just depends on how you want to wear it day to day.
Length stages and what you can do
| Length stage | What you can do |
|---|---|
| Short (grow-out just started) | Style with clay or paste; embrace the shorter look |
| Awkward mid-length | Push it back, use a headband, or add an undercut for shape |
| Around 15cm on top | First small top knot; gather the crown section |
| 20–25cm | Proper top knot and half-up styles hold well |
| 25cm and beyond | Full man bun, low bun, all gathered back neatly |
Tying it so it actually holds
A good knot is half technique, half kit. Here’s the honest method that works day in, day out.
- Start with slightly grippy hair. Freshly washed, silky hair slips out constantly. A little sea salt spray, a light paste, or simply day-old hair gives the knot something to hold onto.
- Brush it back cleanly. Gather everything to your chosen height, high for a sporty top knot, lower for a relaxed bun, using a brush to smooth out bumps.
- Use the right tie. Skip thin elastics that snap and dig in. A proper snag-free hair tie or a spiral coil tie holds better and causes far less breakage.
- Wrap and tuck. Twist the ponytail, wrap it into a coil, and tuck the end under, then secure with a second pass of the tie. A couple of small pins tame any flyaways.
Don’t tie it bone-tight every single day. Constant tension in exactly the same spot is a real cause of hair stress over time, so vary the height and give your scalp a break when you can.
Beating humidity and sweat
This is the part nobody warns you about. Long hair plus Singapore weather equals sweat, frizz and a scalp that can get grimy fast. A few habits make all the difference. Wash your scalp regularly but don’t necessarily shampoo the full length every time, since the ends dry out faster than the roots get oily. After the gym or a sweaty commute, at least rinse and re-tie rather than leaving damp, salty hair knotted up all day, which is a fast track to an itchy, smelly scalp.
For frizz, a small amount of lightweight oil or a smoothing cream on the mid-lengths and ends tames the fluff without weighing hair down. Avoid heavy waxes near the scalp in this heat, as they trap sweat. And on the most brutal days, a slicked-back low bun copes far better than a loose, fluffy top knot. Our guide to men’s hair styling products goes deeper on what to keep in your kit.
When a bun actually suits you
Honesty time, because a man bun isn’t universally flattering and there’s no shame in that. It tends to suit longer or oval face shapes, where the height and pulled-back hair balance nicely. If you have a very round or short face, a high top knot can make it look rounder, so a lower, looser bun usually works better. Your hairline matters too: a bun pulls everything back and exposes the temples, so if your hairline is receding, a softer, less severe tie is kinder than a tight scrape.
Beard pairing is worth a thought as well. A neat bun and a well-kept beard is a genuinely strong combination, balancing the volume up top with structure below. If you’re weighing up whether the look fits your features, our piece on hairstyles for your face shape is a useful read before you commit to the grow-out.
Upkeep and scalp care
Long hair is not low-maintenance, and pretending otherwise leads to disappointment. Even while growing, you need regular trims, roughly every eight to ten weeks, to remove split ends and keep the shape from going wild. If you’re running an undercut, the sides want tidying every three to four weeks to keep the contrast sharp. Condition the length properly, because ends that old have been through a lot of humidity and tying.
Scalp care is the unsung hero here. Tied-up, sweaty hair can leave the scalp flaky and irritated, so keep it clean and consider a gentle exfoliating wash now and then. If you’re not sure your hair is thick or healthy enough to carry the weight of a bun, ask us straight and we’ll tell you honestly.

The honest bottom line
A man bun or top knot is a brilliant look if you’re prepared for the grow-out and the upkeep, and if you play it smart with an undercut and good scalp habits to beat our climate. It’s not a fuss-free option, but it’s a rewarding one. The best first step is a proper chat about your hair type, your face, and whether the commitment fits your life.
