What DR. JACK Brasil does

DR. JACK Brasil is a Brazilian hair care and dermatological cosmetics company operating under the legal entity Jackeline Alecrim ME (CNPJ: 28.523.633/0001-01), founded by scientist Jackeline Alecrim who developed and commercialized a proprietary caffeine-based anti-hair-loss shampoo formulation. The company's core technology combines caffeine with phytoactive (fitoativos) ingredients, marketed as clinically proven and dermatologist-recommended for hair loss (antiqueda), hair thinning, and follicle stimulation. The product portfolio centers on the flagship Linha Therapy Antiqueda, anchored by Caffeine's Therapy Shampoo, with adjacent offerings including the Protocolo Cílios e Sobrancelhas (lash and brow treatment), Magic Beauty Therapy, and bundled combo packages such as Super Combo Antiqueda e Crescimento.

The business operates a dual-channel go-to-market: a direct-to-consumer e-commerce storefront at drjack.com.br with free nationwide shipping above R$200, complemented by an authorized reseller network recruited through the 'Seja Revendedor' and 'Solicitação de Parceria' programs. Pricing is unit-based with aggressive promotional discounting (up to 63% off select bundles) and a PIX payment discount of up to 5%; accepted payment methods include Visa, Mastercard, Amex, Elo, and Boleto Bancário, processed via Vindi. The company also captures informal international demand through a WhatsApp ordering channel for non-Brazil residents.

The company is privately held, bootstrapped, and founder-owned, with a headcount of approximately 9 employees and no disclosed funding rounds, institutional investors, or M&A activity. It is headquartered/operates from Brazil (telephone area code 31 indicating Minas Gerais), and the founder has received recognition in Brazilian media (Exame, Estado de Minas) and in the international publication Hooks Magazine as one of 30 highlighted scientists. No AI/ML capabilities, patents, or regulatory certifications were disclosed.
