TJ's Barber is a barbershop at 124 Main Street in Upper Hutt, rated 4.3 on Google, and it keeps a Facebook page rather than a website.
A barber's craft is mostly clippers and scissors — fades, tapers, crops and beard tidies — done briskly, without salon formality. The most useful thing you can bring is a clear brief: know your clipper guard numbers, bring a photo if you have one, and check you and the barber mean the same thing by "fade". Plenty of barbershops run on walk-ins, so a short wait at busy times is normal. Regulars know the real find is one barber whose hands you trust, since it takes a cut or two to learn how your hair actually sits and grows.
For Upper Hutt locals, having a well-rated barber right on Main Street keeps a decent cut within easy reach.
