IGK Cash In Instant Repair Serum is a lightweight, fast-absorbing hair serum that delivers instant smoothing, frizz control, heat protection, and shine enhancement — formulated for all hair types including fine and color-treated hair that cannot tolerate heavier serum formulas. 1.7oz.

The serum's lightweight silicone and oil hybrid formula creates a thin, protective film over the hair cuticle that seals in moisture, repels humidity, reduces friction-induced frizz, and reflects light for enhanced shine — all without the heaviness or buildup of traditional hair serums. Heat protection actives shield the hair shaft from thermal damage during blow-drying, flat ironing, and curling. The fast-absorbing formula is blended specifically for fine and normal hair — delivering professional-level smoothing benefits without weighing hair down or causing limpness. Apply to damp or dry hair before or after styling. Vegan, cruelty-free, color-safe. IGK is a prestige professional haircare brand founded by a collective of salon owners, built on the philosophy that professional performance and everyday usability should not be mutually exclusive — combining salon-grade technology with clean, thoughtful formulation. Available at Beauty Riche with same-day shipping.
