Protein-powered professional haircare — the science of stronger, healthier hair since 1975.

Joico is a professional haircare brand born in California in 1975 with a mission rooted in hair biology. The brand's science-first approach centres on protein and amino acid therapy — the building blocks of healthy hair — to create formulas that don't just coat the surface but genuinely rebuild and strengthen hair from the inside out.

The K-PAK collection remains Joico's most iconic line, featuring a patented Quadramine Complex of proteins and amino acids that penetrate the cortex to repair bonds broken by chemical services and heat styling. Beyond K-PAK, Joico offers targeted collections for colour care, moisture, curl definition, and scalp health — each built on the same science-driven philosophy.

At ProHair.ca, Joico is a top recommendation for clients with chemically treated, heat-damaged, or structurally compromised hair. The brand is particularly popular for its realistic repair claims and its accessible professional price point.

Frequently Asked Questions

What is the Joico Quadramine Complex?
The Quadramine Complex is Joico's proprietary blend of four molecular-weight proteins and amino acids that penetrate the hair at different levels — from the surface to the inner cortex — to repair damage comprehensively.
Is K-PAK good for bleached hair?
Yes. K-PAK is specifically popular for bleached and highlighted hair because it rebuilds bonds broken during the lightening process. The Reconstructor treatment and Color Therapy line are particularly useful post-bleach.
How does Joico compare to Olaplex?
Both address bond repair but through different approaches. Olaplex uses its bis-aminopropyl diglycol dimaleate technology to reconnect disulphide bonds. Joico K-PAK uses proteins and amino acids to fill structural gaps. Many clients use both — Olaplex during colour services and K-PAK for ongoing strengthening.
Is Joico cruelty-free?
Yes. Joico products are not tested on animals. The brand has a stated commitment to cruelty-free formulation.
Which Joico product is best for everyday use?
InnerJoi is Joico's clean beauty everyday line with gentle, sustainably sourced ingredients for regular use. For damaged hair, the K-PAK Shampoo and Conditioner work well for daily maintenance.
