The original ceramic flat iron brand — professional tools and haircare trusted by stylists worldwide.

CHI (stands for Cationic Hydration Interlink) is a professional haircare and styling tool brand that changed the industry forever when it introduced the world's first ceramic flat iron in the late 1990s. Developed by Houston-based Farouk Systems, CHI's ceramic technology revolutionized heat styling by delivering smooth, even heat distribution that minimised damage and transformed results.

Beyond tools, CHI is also known for its signature Silk Infusion — a legendary leave-in treatment that blends silk proteins with a complex of botanicals to restore damaged hair to silky smoothness. The CHI Keratin line brought Brazilian-inspired smoothing to the professional market, while its colour care line protects salon investment.

At ProHair.ca, CHI represents the gold standard of professional ceramic styling. Whether you're looking for the iconic flat iron, a professional-grade dryer, or the cult-favourite Silk Infusion, CHI delivers reliable, salon-tested performance.

Frequently Asked Questions

Did CHI invent the ceramic flat iron?
Yes. CHI (Farouk Systems) introduced the world's first ceramic flat iron in the 1990s. The ceramic technology provided smoother, more even heat than metal irons and significantly reduced damage — changing professional styling permanently.
What is CHI Silk Infusion?
Silk Infusion is CHI's legendary leave-in treatment that combines reconstructed silk with a botanical complex including other proteins and vitamins. It's applied to damp or dry hair for instant smoothness and shine.
What temperature should I use on a CHI flat iron?
Fine or damaged hair: 300–350°F. Normal hair: 350–400°F. Thick or coarse hair: 400–450°F. Always use a heat protectant like Silk Infusion beforehand.
Is CHI better than BabylissPRO or ghd?
All three are excellent professional brands. CHI pioneered ceramic technology and excels at tools for everyday use. BabylissPRO leads with Nano Titanium for very thick hair. ghd is preferred for its single, precision temperature. Try CHI if you want reliable ceramic performance at a great value.
Is CHI good for curly hair?
Yes. CHI Infra and Argan Oil lines are popular for curly hair clients — particularly the Silk Infusion for frizz control and the curling wands for defining curls.
What is the difference between CHI Infra and CHI Argan Oil?
CHI Infra focuses on silk protein reconstruction and is best for general repair and moisture. CHI Argan Oil uses Moroccan argan oil as its hero ingredient, offering more shine and frizz control with a luxurious finish.
