The Story

West Cork roots, world-class craft

Growing up on the coast of Glengarriff, West Cork, Ireland, Ciarán developed a sharp eye for detail and a deep respect for working with his hands. What began as a trade quickly became a calling.

His award-winning career took him from the barber chair to the biggest stages in sport; cutting for elite athletes and working at international sporting events. Along the way, he earned a reputation for precision, consistency, and a genuine connection with every person who sits in his chair.

But Kiwi's ambition stretched beyond the chair. He saw a gap in the industry — products that over-promised and under-delivered and set out to fix it. That drive led to the creation of Celtic Strand, his own hair care brand built on simplicity, authenticity, and genuine performance.

The Craft

Three pillars, one standard

Everything Kiwi does is built on the same foundation — attention to detail, an honest approach, and a refusal to cut corners.

Barbering

Award-winning cuts delivered at the highest level from everyday clients to elite athletes on the international stage. Precision, consistency, and a personal touch every time.

Education

In-depth video courses and hands-on workshops designed to help barbers at every level sharpen their technique, build confidence, and grow a career they're proud of.

Product

Celtic Strand — Irish-made hair care built on real ingredients and honest performance. No gimmicks, no filler. Just products that work, created by someone who uses them daily.

KiwiSalt by Celtic Strand — sea salt spray crafted with Irish sea salt from Achill Island
Celtic Strand

Minimalistic. Simplistic. Effective.

Born from years behind the chair, Celtic Strand is Kiwi's answer to an industry full of over-complicated products that don't deliver. The hero product — KiwiSalt — is a sea salt spray formulated with pure Irish sea salt brine from Achill Island.

Vegan, cruelty-free, and proudly made in Ireland. It delivers airy volume, touchable hold, and that effortless lived-in finish — nothing more, nothing less.
