What Harklinikken does

Harklinikken (Hårklinikken) is a privately held, founder-led hair care company that develops and sells a personalized, scalp-first hair growth system built around its proprietary Hair Gain Extract. The Extract is a hand-blended, individually customized topical treatment formulated from fermented botanical ingredients (including burdock root, marigold, apple, sandalwood, and cow's milk derivatives) combined with naturally occurring sterols, tannins, flavonoids, and fatty oils. Each bottle is adjusted for the specific client over the course of treatment based on scalp response, drawing on 33+ years of development informed by clinical findings from more than 100,000 clients across three continents and ten countries.

The company's product portfolio extends beyond the flagship Extract to include three cleansing shampoos (Balancing, Stabilizing, Fortifying), multiple hydrating and conditioning products (Daily Conditioner, Weightless Conditioner, Hair Hydrating Crème, Hair Mask), styling products, accessories, and a vegan internal Hair Supplement launched in 2024 after more than a decade of development. The Hårklinikken Method integrates these products into a multi-step regimen focused on optimizing scalp pH, microbiome, and barrier health as the foundation for hair growth, marketed as a drug-free alternative for androgenetic, hormonal, stress-related, postpartum, and post-chemotherapy hair thinning.

Harklinikken operates a hybrid DTC model: a Shopify-powered e-commerce storefront with subscription management via Recharge, paired with two flagship US clinics in New York and Beverly Hills offering in-person consultations with Hair Specialists using magnified scalp cameras and baseline photography. The company is legally domiciled as Harklinikken, L.L.C. in Florida (US headquarters in Tampa), with original R&D operations in Copenhagen, Denmark. Revenue is generated primarily through recurring 1-, 3-, and 6-month subscriptions to the customized Extract, complemented by supporting haircare product sales, supplement subscriptions, and consultation services. International distribution spans dedicated regional storefronts for Europe, the UK, Denmark, and Dubai, with shipping to Canada, Australia, Singapore, Japan, and other markets. The business is privately held by founder Lars Skjøth, with no disclosed institutional investors or external funding rounds.
