Despite having differing textures, lengths, and tones, most of us aspire for hair that’s shiny, healthy, and full — key indicators of healthy tresses. Fortunately, shine-inducing sprays, thickening lotions, and hair-growth serums exist, though not every product offers all three benefits, as Viviscal’s Thickening Serum does. 

The Viviscal Thickening Serum is a leave-in hair treatment that envelops strands in a densifying, lightweight formula. Hailing from a brand that specializes in growth-promoting supplements and follicle-enhancing topicals, Viviscal’s lotion-like styling cream plumps thinning, lackluster hair in seconds. Over time, it strengthens feeble strands, smooths frizz without leaving the greasy residue inherent to many strand-smoothing products, and imparts lustrous shine to give hair a healthier appearance overall. Best of all, the multi-tasker is on sale at Amazon, where it’s $14 right now.

The serum-like leave-in treatment is straightforward to use, per shoppers, and works on wet or dry hair, making it versatile and a breeze to incorporate into any existing styling routine. Moreover, it’s ideal for all hair types and textures and safe for color- and keratin-treated hair.

Key ingredients include biotin, a form of vitamin B, and keratin, the structural protein that functions as a building block for nails and hair. Biotin, when taken in supplement-form, may improve hair strength and promote new growth; as a topical ingredient, it adds moisture and shine. Keratin functions as a strengthening ingredient when used topically, hence its prevalence in fortifying hair products and inclusion in Viviscal’s serum. 

Shoppers are impressed by the formula — both for its instant and long-term benefits. According to one reviewer whose strands had sparsened post-illness, the serum “volumizes” and promotes a “bountiful” head of hair. Similarly, another reviewer says the serum “provides weightless volume.” Yet another fan swears their hair was “thicker [and] fuller” after using the product for only a week; after one month, it looks “20 percent fuller,” they claim. Finally, a shopper whose hair is naturally “very fine” says Viviscal’s serum imparts thickness and tames “flyaway ends.”

For thicker hair, plus less frizz and more shine, shop the Viviscal Thickening Serum while it’s on sale at Amazon for $14.
