Refolliq

Refolliq is a hair-loss treatment line owned by TheOTCLab B.V., a consumer healthcare company based in Amsterdam, the Netherlands [8]. The range consists of three products meant to be used together: a topical lotion, a scalp shampoo and an oral supplement. It is aimed at both men and women dealing with thinning hair or excessive hair loss.

The brand builds its identity around science-based formulation and transparency, and it says its products are vegan and free from animal testing. Its central product, a hair growth lotion, relies on two branded ingredients developed by outside ingredient suppliers. Refolliq does not publish a founding date or name its founders, and no independent press coverage of the brand is documented.

Refolliq belongs to TheOTCLab B.V., whose head office is on Fred. Roeskestraat in Amsterdam [1]. The parent company says it was founded in 2016 by two entrepreneurs [8]. It describes itself as a full-service healthcare company focused on over-the-counter (OTC) products, meaning health and self-care items sold without a prescription. Its stated activities span product development, export, in-licensing, acquisitions and distribution, and it says it is active in more than 44 countries.

TheOTCLab splits its portfolio into brands it owns and brands it distributes on behalf of other companies. On its homepage it names Refolliq among its own brands, alongside the wart treatment Dr. Yglo, the nail-fungus range FungeX and the wart remedy Acetocaustin. The distributed brands it highlights include Breathe Right, Audispray and Just For Men. Most of the company's own brands address everyday medical complaints such as warts, nail fungus, head lice and ear hygiene, which places Refolliq at the cosmetic end of a largely self-care portfolio.

TheOTCLab's dedicated overview page for its own brands does not list Refolliq, even though the company's homepage does [9]. The parent has not publicly explained the difference.

Packaging and retail listings both identify TheOTCLab as the company behind the line. The German package insert for the lotion names TheOTCLab in Amsterdam as manufacturer and supplier [10], and German retail listings name TheOTCLab B.V. as provider and manufacturer [12]. Where the products are physically made is not stated.

The brand's history is sparsely documented, and no launch date has been announced. The earliest dated material on its German-language website is its philosophy page, published in November 2023. The package insert for the German version of the lotion carries a print date of August 2024. Refolliq operates websites in German, Dutch, French and English.

Refolliq presents itself as a treatment for hair loss rather than a general hair-care brand. Its stated mission is to help people tackle hair loss effectively so they can feel self-confident again. The company says it is guided by science and compassion, and it names transparency, quality and efficacy as the focus of its work.

The brand's message reaches beyond regrowth itself. According to Refolliq, its treatments are about more than restoring hair; they are meant to help people enjoy life with renewed energy. Its German tagline, "Lass dein Haar auf natürliche Weise nachwachsen", translates as "Regrow your hair naturally".

The three products are presented as a routine in which each step supports the others. The shampoo cleanses and exfoliates the scalp, the lotion is applied to thinning areas, and the capsules are meant to work from the inside out. The brand calls this a holistic, whole-body approach to hair loss.

Refolliq states that its products are 100 percent vegan and not tested on animals [2]. These are the company's own statements; no third-party vegan or cruelty-free certification is documented.

### Revitalising Hair Growth Lotion

The lotion, sold in German as Revitalisierende Haarwachstums-Lotion, is the core of the range. It comes as an 80 ml spray. According to its package insert, two to three sprays are applied to each thinning area of the scalp, ideally morning and evening. The insert states that one bottle lasts at least a month and that the first results become visible after three months [10].

The formula is built around two branded ingredients. The insert identifies Redensyl as a registered trademark of Givaudan and Sepicontrol A5 as a registered trademark of Seppic [10], so neither is Refolliq's own technology. Refolliq describes Redensyl as a blend of plant-derived components made with biotechnology. The company says it reactivates dormant stem cells in the hair follicle, lengthening the growth phase of the hair cycle while shortening the resting phase [3]. Sepicontrol A5 is described as an amino-acid compound combined with cinnamon extract. Other ingredients on the insert include green tea leaf extract, larch wood extract, menthol, and zinc, manganese and copper compounds. The brand says menthol boosts blood flow to the scalp and helps the lotion absorb.

The packaging promotes a "5-fold" action and describes the lotion as dermatologically and clinically tested and free of SLS (sodium lauryl sulfate, a common foaming agent). Its headline efficacy claim is that the lotion stimulates stronger hair growth, prevents hair loss and improves hair density, leading to fuller hair. On the insert, that claim is footnoted as tested on 41 people [10]. A Dutch online drugstore's guide to the routine adds that the test ran for 24 weeks [11]. No independent study of the finished product is documented.

The insert also carries safety warnings. The lotion is for external use only and should not be used on children under three or on a scalp with wounds or abrasions. Its label also states that it releases formaldehyde [10].

### Deep Cleansing Hair & Scalp Shampoo

The shampoo is positioned as the first step of the routine. The company says it removes product build-up, exfoliates the scalp and restores moisture. Its key ingredients, according to Refolliq, are 3 percent salicylic acid, which loosens dead skin and controls excess oil, and 2 percent climbazole, an antifungal agent used against dandruff. It also contains niacinamide, a form of vitamin B3.

### Nutraceutical Hairbooster Complex

The third product is a capsule supplement intended to nourish hair, skin and nails. Refolliq lists biotin and the amino acid L-cysteine among its key ingredients, describing L-cysteine as a building block of keratin, the protein that makes up hair. The supplement takes the range beyond topical hair care into oral nutrition.

Refolliq's German website was last updated in mid-2025, and no brand news or new product launches are documented from the past year. The most recent third-party material is a three-step routine guide published by the Dutch online drugstore De Online Drogist in May 2025 [11]. The brand's absence from its parent's own-brand overview page, while it still appears on the parent's homepage, leaves its place in TheOTCLab's portfolio unclear.
