Philip Kingsley

Philip Kingsley is a British haircare brand built around trichology, the science of the hair and scalp. It grew out of the London clinical practice of its namesake founder, the trichologist Philip Kingsley (1930–2016), and remains active today with a live online store, current product ranges, and consultation clinics in London and New York. Since the founder's death, his daughter Anabel Kingsley has led the company as Brand President and consultant trichologist.

The brand's central idea is that hair and scalp should be treated as a matter of health rather than styling alone. It describes its approach as "complete wellness for your hair and scalp, from the inside out," and defines trichology, in its own words, as being "to your hair and scalp what a dermatologist is to the skin on your face and body." That clinic-led positioning, rather than any single product category, is what the company presents as its distinguishing feature.

Philip Kingsley was born on 4 June 1930 in Bethnal Green, in London's East End, to a Jewish family; his father was a tailor and his mother a seamstress [12]. According to editorial accounts, he began working in his uncle's East End hairdressing salon as a teenager, then studied hair and scalp science by correspondence with the Institute of Trichologists because he could not afford university. He qualified as a trichologist in 1953.

The dating of the brand's founding depends on what is being counted. Wikipedia and editorial sources record that Kingsley opened his first London clinic in 1957, and the company's practice is the continuation of that clinic [12]. The brand's own site does not give an exact year, instead describing "over 60 years of Trichology expertise," which is consistent with a 1957 origin [1]. The 1957 clinic date is the earliest precise founding year documented across sources.

Kingsley went on to become chairman of the Institute of Trichologists and authored four books on hair care, among them The Hair Bible (2003). He is credited with several industry firsts, including linking hair health to nutrition and creating the first pre-shampoo conditioning treatment, and Wikipedia notes he "apparently coined the phrase 'bad hair day'" [12].

The product most associated with the company, the Elasticizer, dates to 1974. Both the brand and outside sources say it was created for the actress Audrey Hepburn, whose hair had been left dry and damaged by repeated heat styling and colouring on film sets; Wikipedia ties its creation to the making of the film Robin and Marian [12]. The company recounts that Hepburn "used to have pots of it shipped to her home in Switzerland," where the original formula was a thick paste that had to be mixed with water at home. Marketed as the world's first pre-shampoo conditioning treatment, it was formulated to add moisture without weighing fine hair down.

The practice expanded to Fifth Avenue in New York City in 1977. In 1982 the Elasticizer was made available at Saks Fifth Avenue, taking it beyond the clinic's own clientele for the first time [13], and the wider product line was formalised in 1983. In 1984 Kingsley introduced Swimcap, a conditioning treatment developed for the United States Olympic synchronized swimming team [12]. Following the founder's death in 2016, at the age of 86, Anabel Kingsley took over leadership of the brand.

The brand remains associated with the Kingsley family and continues under Anabel Kingsley as Brand President. No parent company or acquisition history is recorded in the available sources.

The company positions itself as trichology-led and holistic, framing hair care as part of overall wellbeing rather than a matter of cosmetics. Its guidance states that "healthy hair does not happen overnight – it happens over time," and that results depend on self-care as much as on products. In its educational material it avoids the labels "normal," "dry," and "oily," classifying hair instead by texture into four categories: fine, medium, coarse, and natural coiled curls. The London clinic, at 54 Green Street in Mayfair, and a New York centre continue to offer consultations alongside the retail range, and the brand markets itself at a prestige, salon-quality tier.

Beyond the Elasticizer, the brand's ranges include Density, aimed at hair thinning and shedding, whose Density Preserving Scalp Drops the company says are "trichologist-approved to reduce hair shedding" after a minimum of three months of daily use, on the basis of an independent clinical trial. The Elasticizer itself is described by the company as "clinically proven to reduce breakage" after a single use. Its stated hero ingredients are castor and olive oil, which, in the brand's account, seal the cuticle while excess residue washes away so the treatment does not weigh hair down.

Products are described by the company as vegan and cruelty-free "by default," free of parabens and sulphates, and made in the United Kingdom. The brand also states that it never tests on animals. No third-party cruelty-free certification is named in the sourced material.

The company reports reducing its packaging footprint since 2019, saying it has "removed 95% of our cardboard cartons from the shelves" and switched remaining cartons to FSC-certified stock. It uses post-consumer recycled plastic and a sugarcane-derived bioplastic, and describes the latter as carbon-negative, stating that producing the material absorbs "more than 5 kg of CO2" for every kilogram used [4]. The homepage summarises this as a "CO2 negative" position.

The brand also has a record of charitable giving. It supports The Royal Marsden Cancer Charity — which treated the founder's wife, Joan — donating proceeds from its UK site each year on 4 June, the founder's birthday, alongside partnerships with Look Good Feel Better and Hospice UK.

In the press, Kingsley was given a series of nicknames that recurred across coverage: "Hair Guru" by The New York Times, "Hair Wizard" by Vogue, and "Hair Doctor" by The Sunday Times, for which he also wrote advice columns [12]. His clientele was widely reported and included Audrey Hepburn, Laurence Olivier, Jane Fonda, Mick Jagger, Gwyneth Paltrow, Cate Blanchett, Sienna Miller, and British royalty [12].

The Elasticizer in particular has been treated as a long-running cult product. A 2020 Who What Wear feature called it "the OG of hair masques," a product that "almost instantly solidifies a spot in the beauty hall of fame," and positioned it as a precursor to later treatments such as Olaplex [13]. The frequently cited sales figure for the treatment has varied between sources: the same 2020 feature reported that a tub was "sold every two minutes worldwide" [13], while the brand's current product page states that one is sold every 17 seconds [3].

The brand is active. Its site lists current ranges, including Density and Bond Builder, and both the London and New York clinics continue to operate under Anabel Kingsley [1]. Its products are sold internationally, including across the Nordic markets. Although the founder died in 2016, the company has continued under family leadership, presenting itself as the ongoing expression of his trichology-led practice.
