Capillus (capillus.com) is the world's leading FDA-cleared laser therapy cap brand for hair loss treatment — founded in 2012 and trusted by thousands of hair restoration surgeons, dermatologists, and patients worldwide as a clinically backed, non-invasive solution for androgenic alopecia (male and female pattern baldness). Using Low-Level Laser Therapy (LLLT) technology in a discreet, wearable cap format, Capillus makes professional-grade hair restoration treatment as simple as wearing a hat for six minutes a day. The Capillus product lineup is designed around precision and convenience. The entry-level Capillus Focals delivers 410mW of laser energy through 112 medical-grade laser diodes at $399 — making it the most accessible entry point into clinically backed LLLT therapy. The CapillusPro is the brand's most clinically validated model, backed by an independently reviewed clinical trial with results published in the peer-reviewed journal Dermatologic Surgery, demonstrating measurable improvement in hair count and thickness after consistent use. The flagship Capillus Spectrum elevates the technology further with 312 laser diodes and a proprietary dual-wavelength system combining 650nm red light for surface follicle stimulation with 808nm near-infrared light for deeper scalp tissue penetration — delivering the most comprehensive follicular coverage available in a personal LLLT device. All Capillus caps use safe, non-thermal "cold" lasers that carry no meaningful risk of scalp damage and can be used at home, at the office, or on the go. The companion Capillus App provides session reminders, before-and-after photo tracking, personalized settings, and access to exclusive promotions. Beyond laser caps, Capillus also offers a complete clinical hair care product line, Keratin fiber concealers for instant coverage, and an expanding range of red light and near-infrared therapy devices for brain health and physical recovery. Capillus offers free US shipping on orders over $50 and backs all laser therapy cap purchases with a satisfaction guarantee covering results within the guarantee period. Warranty coverage of one to three years applies depending on the model purchased, with product registration required within 30 days to activate coverage. Flexible financing through Affirm makes payments manageable across 3, 6, or 12-month installment plans. Coupon codes are periodically available at checkout for additional savings, and veterans and active military receive exclusive verified discounts.
