Oiamiga

Oiamiga is a British permanent hair-dye brand made by Herb UK, a hair-cosmetics manufacturer based in Lymington, Hampshire [7]. It markets a range of at-home colour positioned around inclusivity and environmental responsibility, and is sold in the United Kingdom, the United States and the Nordic market. The brand remains active, with a live e-commerce site, current social channels and retail distribution.

Herb UK describes Oiamiga as the newest brand in its portfolio and frames it as "the first fully inclusive, gender-full (not gender-free) hair dye," created to reach customers "no matter who you are, how you identify, or how you do life" [6]. No source states an explicit founding or launch year; the brand appears to have emerged in the early-to-mid 2020s.

The Oiamiga name is invented. According to the company, it was coined partly from Portuguese after the founders struggled to find an available trademark, and is meant to convey the identity of "an inclusive, planet-conscious brand; a friend to all" [2]. The pronunciation is given as "oi-uh-mee-guh".

The exact founding year is unverified. No available source gives a launch date: Herb UK's announcement refers only to having "recently launched the website" without a published date, while other indicators suggest the product existed by the early 2020s [6]. Because no source confirms a specific year, the founding date is left open here rather than fixed.

Oiamiga is owned and produced by Herb UK, which presents itself as "Britain's leading manufacturer of natural plant-based hair colour, care and styling cosmetics since 1990" [7]. The company is based in Lymington and also operates a facility in Rochester, Kent. Alongside Oiamiga, Herb UK's portfolio includes Organic Colour Systems, Tints of Nature, Pin-Up Perm and Bio-Health.

Oiamiga's central theme is inclusivity. Its stated belief is "that great hair is for everyone, regardless of age, race or gender," and the company describes the line as designed for "all; no matter their gender, ethnicity or age," with a minimum recommended age of 16. The homepage tagline reads "Say goodbye to outdated beauty standards and hello to hair liberation!"

The brand pairs this with an environmental message it labels "Planet Positive," covering packaging, ingredients and charitable giving (see Sustainability).

The core product is a permanent hair dye offered in 15 shades spanning natural and fashion colours, including names such as Natural Blonde, Chocolate, Jet Black, Raspberry, Silver and Tangerine. The company says the colour is suitable not only for the head but also for beards, moustaches and body hair, and that it covers grey hair [6]. The range is supported by a Charcoal Shampoo and by pre- and post-colour treatments.

A formulation feature the company highlights is its "Rapid Activator," which it describes as an innovation enabling faster processing — colour in as little as 20 minutes — alongside improved intensity and longevity [4]. On chemistry, Oiamiga states its formulas contain no ammonia and no henna, but do include PPD (a common oxidative dye pigment) "in the lowest possible quantities which reduces the risk of reaction" [4]. The third-party retailer gentlehairdye.com lists the result as lasting up to 12 weeks depending on hair condition and washing habits [9].

Oiamiga's "Planet Positive" framework groups several environmental and social commitments. The company says its products use "100% recycled and recyclable cartons and bottles," that colour bottles are made from "100% ocean-bound plastic," and that it plants a tree for every 100 packs sold [3]. It also states that it donates to organisations including Greenpeace, Plantlife and Orangutan Appeal UK [3].

On animal welfare, all of the colours are accredited by the Vegan Society and described as cruelty-free [4]. Herb UK adds that the products are ammonia-free and made using certified organic and natural ingredients.

Oiamiga is active. It operates a live e-commerce site with a current product range, maintains social accounts on Instagram, TikTok and Facebook under the handle @oiamiga.official, and is distributed in the United Kingdom and the United States. Its backing by Herb UK, a manufacturer operating since 1990, supports its continued production.
