Gallagher Fragrances O'Hello is an Eau de Parfum launched in 2023, created by Daniel Gallagher. Gallagher Fragrances's O'Hello carries an Acquired verdict, a green-led wear.

O'Hello is a citrus-led floral with a long note list, from neroli and bergamot to tuberose, oakmoss and sandalwood. It is bright up front and soft underneath, an easy unisex choice for daytime. Busy on paper, but the mix of citrus and white flowers should keep it friendly.

Scent Profile

Composition

Timeline

Showing: Overall Blend

Top, heart and base are the brand's own listing, not a timing claim - the industry classifies a note by its character as much as by how fast it fades. Each curve here is modelled from that material's own volatility, so groups can overlap when a house lists long-lasting materials in its heart.

The large name is the everyday one. The small name is the INCI form on the box, so you can compare the two. Reactions differ between people. A patch-test panel is not a ranking of risk. How we derive this

About

O'Hello is listed as one long set of notes rather than a pyramid, but the picture is clear. Bergamot, bitter orange, Italian green mandarin orange and neroli bring a bright citrus lift, with basil, ginger and violet leaf adding green and spicy edges. Orange blossom, tuberose, jasmine, ylang-ylang and iris supply the floral core, creamy and white. Underneath sit oakmoss, patchouli, sandalwood, musk, Ambroxan and Iso E Super, which give a clean, woody, mossy finish. It is a fresh floral with a modern, airy feel, aimed at people who want a bright scent with some depth.
