The bottom line: this serum is for someone who wants a non-greasy, daily-use product that layers easily under styling products and does not weigh hair down. Our review found the texture and water base to be the single biggest reason to buy, since it feels like a leave-in treatment rather than an oil, making it suitable for frequent use on all hair types.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater-based formula:\u003c\/strong\u003e Provides a non-greasy, lightweight feel that absorbs quickly so hair does not look weighed down after application.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickening support:\u003c\/strong\u003e Formulated to support the appearance of thicker, fuller-looking hair when used consistently as part of a routine.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAll hair types:\u003c\/strong\u003e Designed to be compatible with a wide range of textures and styles, from fine and straight to curly and coarse.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDaily leave-in use:\u003c\/strong\u003e The serum is intended for regular application and layers well beneath other styling or finishing products.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact size:\u003c\/strong\u003e The 1.8 oz container is convenient for travel or trial use without committing to a large bottle.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis serum is best for people noticing some loss of density or who want a cosmetic boost that makes hair look fuller without adding residue.
