The Hair Diagram

The Hair Diagram sells adhesives, removers, scalp protectors, lace tint sprays, and application tools for lace-front wigs and hair systems. Prices sit in the budget-to-mid range: most glues and removers run $8–$20, while kits stay under $35. The brand is direct-to-consumer, shipping worldwide from its Houston headquarters and listing select SKUs on Amazon. Bonding strength and skin-safe formulas are the core promise; the company formulates water- and acrylic-based adhesives that hold 2-4 weeks yet rinse off with water-based removers. Its “Bold Hold” line—especially the yellow-label Maximum Glue and Skin Protect—has become a staple on wig-install TikTok, giving the brand outsized visibility among DIY wearers and salon techs. Customers are primarily Black women aged 18-40 who switch styles frequently and value neat, long-lasting installs at home. They look for dermatologist-tested, non-irritating solutions and follow social tutorials that feature the brand’s bright, color-coded packaging as a trust cue. The Hair Diagram competes in the crowded wig-adhesive segment against generic salon glues and niche lace systems. It differentiates with beginner-friendly education (step-by-step videos, QR-coded instructions), fast U.S. shipping, and a tight SKU set that solves the full install/removal cycle under one brand umbrella.
