A prescription product that moved onto the open shelf.

Selsun Blue started life inside a pharmaceutical company. A Form 8-K filed by Chattem, Inc. on 8 March 2002 states that the shampoo was launched by Abbott Laboratories in 1953 as a prescription drug, and that in 1974 it was introduced as an over-the-counter medication. The same filing records that the over-the-counter product contained 1% selenium sulfide and that a 2.5% prescription strength, known to dermatologists, was still sold, with about half of foreign sales in the stronger formula.

The name comes from the ingredient. English Wikipedia describes “Selsun” as a portmanteau built from selenium sulfide and the letter n. Since leaving prescription-only status the brand has moved from the pharmacy counter into wider retail; English Wikipedia says Chattem sells it alongside its other products through mass merchandisers, drug stores and food retailers.

Abbott kept the brand for close to half a century. The trade newsletter The Tan Sheet, reporting on 11 March 2002, named the seller more precisely: Chattem had agreed to buy the line from Ross Products, a subsidiary of Abbott Labs. Chattem’s filing gives the date of the announcement as 5 March 2002 and describes the product as “a medicated dandruff shampoo”.

From Abbott to Chattanooga, then to Sanofi and Opella.

The buyer was an old Tennessee company. English Wikipedia records that Chattem was founded in 1879 by Zeboim Cartter Patten as the Chattanooga Medicine Company, adopted the name Chattem and went public in 1969, and has remained in Chattanooga. Its strategy, the same article says, was to buy consumer brands it judged under-marketed and to advertise them hard; its portfolio came to include names such as Gold Bond, IcyHot, Aspercreme and Rolaids.

Chattem’s 8-K set out how the handover would work. The acquisition covered worldwide rights to the brand, except in India, together with related intellectual property and certain manufacturing equipment. Abbott was to keep making the shampoo for Chattem at first under a contract manufacturing arrangement, and Chattem said it expected to move certain production to its own Chattanooga facilities within 12 to 24 months of closing. Outside the United States, Abbott or its contract manufacturers would continue to make the product until Chattem signed its own agreements with foreign contract manufacturers.

HBW Insight, in an item from The Rose Sheet dated 24 March 2003, confirmed that Chattem had bought Selsun Blue in March 2002 and reported that the company renewed advertising support for the brand in June of that year. Chattem then widened the range. English Wikipedia says the company announced a line called Selsun Salon from 1 November 2005, built on a different active ingredient, pyrithione zinc, and aimed at the higher-priced end of the shampoo aisle.

Chattem itself changed hands at the end of the decade. A Sanofi-aventis release dated 11 March 2010 announced that it had completed its acquisition of 100% of Chattem, which became a wholly owned subsidiary of the French group; the offer had been announced in December 2009. Sanofi later gathered its consumer-health business into a unit that English Wikipedia says was created in 2018 and renamed Opella in 2020. Sanofi announced in October 2024 that it would sell half of Opella to the investment firm Clayton, Dubilier & Rice, a sale Le Monde reported as completed on 30 April 2025. English Wikipedia says Chattem now does business as Opella North America, and the footer of the Selsun Blue website carries an Opella Healthcare Group copyright.

Design and documentation.

The brands in this group are mass hair-care, dandruff-shampoo and home hair-colour names, the kind sold from drugstore and supermarket shelves rather than salons. Many of them have passed through several owners, from the families or chemists who started them to large consumer-goods groups and, in some cases, to smaller companies that buy older brands and keep them on sale.

On a crowded shelf, a hair-care brand is usually recognised before it is read. A bottle colour, the shape of a cap, a logo set in a particular letterform or a slogan repeated over decades can carry the name further than any single formula. Home hair colour adds its own visual language: the box with a model’s face, the shade chart with numbered and named colours, and the promise that the result will match the picture.

Each guide separates what independent sources record from what the company says about itself — who founded the brand, who owns it now, where its products are made and how its packaging and advertising have changed — and marks plainly what rests only on the company’s own word.

A colour in the name, and a lowercase b.

The brand’s own spelling has shifted. Chattem’s 2002 filing and English Wikipedia write the name as two capitalised words, Selsun Blue. The current United States website, fetched in October 2026, sets it as “Selsun blue®”, with a lowercase b, throughout its menus, product pages and offers, so the colour word reads as a description attached to the name rather than a second proper noun.

Range names have followed Chattem’s and Opella’s marketing. English Wikipedia says that by 2011 the brand was organised in two segments, Naturals and a base line, and that Deep Cleansing, a version with scrubbing micro beads, was launched by Chattem in January 2011. An archived copy of selsunblue.com from 2012 shows a menu of Selsun Blue, Selsun Blue Deep Cleansing, Selsun Blue for Itchy Dry Scalp and Selsun Blue Naturals, followed by links for what was new, where to buy, frequently asked questions and advertising. The current site groups its shampoos into Max Strength, Daily Care and Naturals, with a quiz that recommends a product and an education section of short articles.

Across its owners the constant has been the name itself: a pharmaceutical coinage from an ingredient, joined to a single colour word. For a design guide, Selsun Blue shows how a technical product name can be softened by a colour word, and how a change of capitalisation alters the tone of a brand. Compare it with Head & Shoulders, another American shampoo sold in the same category, and Prell, a long-running American shampoo brand. For this guide we use blue, navy and ice tones with a rounded sans, an unofficial interpretation; no product or logo is reproduced.
