Designed to replace multiple products, the serum works on damp or dry hair to seal cuticles, control flyaways and improve manageability without weighing strands down. It's formulated for color-treated, chemically processed, fine-to-coarse hair and omits sulfates, parabens and drying alcohols.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I use this serum for best results?\u003c\/h3\u003e\n\u003cp\u003eApply a small amount to towel-dried hair to detangle and smooth before styling, or use a tiny touch on dry hair to tame flyaways. Start with the recommended drop count for your hair thickness and increase only if needed to avoid buildup. It layers well under other styling products and rinses out easily in your next wash.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFine hair: 1 drop distributed mid-length to ends\u003c\/li\u003e\n  \u003cli\u003eMedium\/wavy hair: 2 drops, focusing on frizz-prone areas\u003c\/li\u003e\n  \u003cli\u003eThick\/curly hair: 3 drops, emulsified in palms then applied\u003c\/li\u003e\n  \u003cli\u003eUse before heat styling for thermal protection up to 450°F\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat benefits can I expect after one bottle?\u003c\/h3\u003e\n\u003cp\u003eRegular use delivers smoother texture, less humidity-driven frizz and a polished shine that looks like a salon finish. The keratin and collagen form a light coating on strands to reduce breakage and improve elasticity, while biotin and oils help maintain moisture balance and shine.
