Nioxin Volumizing Reflectives Thickening Spray Is a thickening and volumizing spray for fine hair. An extremely light weight spray allowing for effortless body building style. Nioxin Volumizing Reflectives Thickening Spray adds thickness from inside the cuticle and strengthens the hair shaft while adding body, volume, texture, fullness, and shine to fine hair without build- up or weight. Glyco-proteins add dimension from inside the hair shaft, and cystine amino acids repair damaged cuticle providing volume, strength, support and protection to the hair shaft. Glycerin binds moisture deep with the hair shaft providing a defense against dry and frizzy hair. Volume Enhancers provide durable and elastic hold, even in high humidity.
