Miriam Quevedo

Miriam Quevedo is a Spanish luxury hair, scalp and skincare company based in Barcelona. It was founded by the namesake beautician Miriam Quevedo together with her husband, Juan Manuel, and is built around a "scalp-first" idea: treating the scalp with the same anti-aging attention usually reserved for facial skin. The company describes its formulas as "green biotech for your hair and scalp rejuvenation," combining biotechnology with costly raw materials such as caviar extract, 24K gold and platinum and diamond powders.

The brand remains active. It sells across more than 40 countries through department stores and luxury hotel spas, maintains a current social presence, and in recent years has positioned itself around the line "Hair Longevity Pioneer."

Quevedo's interest in cosmetics began in childhood, working in her mother's herbal apothecary in Barcelona, where she handled herbs, oils and powders. She later trained as a beautician and masseuse and, according to one founder interview, earned a degree in economics from the University of Barcelona before completing a master's at a Barcelona business school [5].

The company's two founding figures are Quevedo and her husband, Juan Manuel, described as her high-school sweetheart and business partner. His family had run a cosmetics manufacturing and R&D operation for around 35 years, and the venture paired her knowledge of natural and rare ingredients with his manufacturing and laboratory base [5][6].

Sources differ on when the brand began. Gulf News dates the formation of the MQ company to 2002, when Quevedo and her husband set it up together [7], and that corporate-formation date is taken here as the founding year. A Dermstore interview instead states the brand launched in 2005 [6], the year Quevedo released her first skincare line; the two dates reflect the gap between forming the company and shipping the first products rather than a genuine dispute over the history.

After forming the MQ company in 2002, Quevedo launched her first skincare line in 2005. In 2007 she introduced Extreme Caviar by Miriam Quevedo, a haircare line framed around an anti-aging approach to hair, which became the brand's entry point into the category it is now known for [5]. Sublime Gold and, later, the Platinum & Diamonds range followed, extending the use of precious-material ingredients across the catalogue.

The company also operates in the spa channel. According to brand material compiled across sources, Hair Spa by Miriam Quevedo, described as a spa dedicated to hair and scalp rejuvenation, is located at the Mandarin Oriental hotel in Barcelona.

The core of the brand's thinking is that healthy hair depends on a healthy scalp. As Quevedo put it in one interview, "you can't have great hair unless you have a healthy scalp and follicles, which is skin care" [6]. From that premise the company applies skincare logic — actives, serums and treatments — to the scalp, hair follicle and fiber, and centres its messaging on anti-aging for both hair and skin.

Positioned at the luxury end of the market, with rituals priced at roughly EUR 100 to 300, the brand frames itself as combining "luxury with efficacy." It describes biotechnology as "the cornerstone" of its formulations, citing processes such as stem-cell extraction, the development of new molecules and bio-mimicking technology. The company states that about 80% of its ingredients are natural, with a further 20% derived from natural origins [5].

Miriam Quevedo's catalogue is organised into named collections, several built around a signature precious ingredient. The Glacial White Caviar line is formulated with white caviar oil, encapsulated Swiss glacial water and marine bamboo; Sublime Gold uses micronized 24K gold; Platinum & Diamonds is built around micronized platinum and diamond powder; and Black Baccara draws on a rare black rose and plant stem cells. The earlier Extreme Caviar line targets concerns such as thinning, dandruff and color damage. Other recurring actives across the range include rose stem cells, peptides and hexapeptides, and argan oil.

On the technology side, the company promotes a proprietary AminoShot Technology, which it says boosts hair volume and fiber thickness by up to 30% and which it describes as patented [8]. Formulation and clinical testing are carried out at what the brand calls the MQ Lab in Barcelona [8].

The company also makes a series of "clean beauty" and free-from claims. It states that its products are free of sulfates, parabens, mineral oils, phthalates, paraffin and petrolatum, and that all of its products are cruelty-free [3]. According to the brand, the Black Baccara haircare collection is fully vegan and the matching skincare collection is almost entirely so [3].

The brand and its founder have been the subject of beauty-press profiles, including a Gulf News piece headlined "Miriam Quevedo is the haircare queen" [7] and interviews with Dermstore and Emirates Woman. Retailers and editorial coverage frequently describe the line as "award-winning," though specific awards are not detailed in the available sources.

Miriam Quevedo is an active, privately held company; the consolidated brand material identifies the legal entity as MIRIAM QUEVEDO SL in Barcelona. It maintains an Instagram account with roughly 41,000 followers and recent posts, and continues to distribute through retail partners such as Neiman Marcus, Bergdorf Goodman and Lane Crawford, alongside hotel and spa partners including Mandarin Oriental and Marbella Club [5]. Recent positioning around "Hair Longevity" and the AminoShot-based Platinum & Diamonds line indicates ongoing 2024-era activity [11].
