Viviscal’s Thickening Shampoo Makes Hair Fuller After One Use

When I embarked on a hair growth journey a few months ago, it felt daunting. After all, there’s hardly a shortage of tinctures, foams, and other elixirs that promise rapid hair-sprouting benefits. Efficacy aside, many formulas have proved to be a hassle to apply, whether because of unpleasant sensorial elements (funky smell, oily residue), or simply because of the hassle they added to my already-scrambled haircare routine. 

Luckily, hair growth shampoos like the Viviscal Thickening Shampoo exist—promising thicker, longer hair without hassle. Visical’s formula is a favorite among shoppers, who swear it’s filled in sparse spots and prevented shedding—quickly. Better yet, the shampoo is 30 percent off at Amazon for Prime Day, where it’s a mere $9 for a limited time. 

Viviscal Thickening Shampoo

The Viviscal Thickening Shampoo is a strand-plumping, growth-promoting solution for fine, limp hair. In addition to imparting a fuller appearance almost instantly, the formula contains ingredients known to strengthen breakage-prone strands, ultimately allowing hair to grow to new lengths and reach its healthiest, bounciest potential. 

The formula is packed with keratin—a protein that is a major building block for  hair. When hair endures damage from styling treatments, color, or heat, the hair’s keratin composition can be compromised, leading to feebleness and a greater risk of breakage. Adding keratin back into hair fortifies the strands ultimately yielding stronger, healthier hair. 

Biotin is also in the formula. The B vitamin, while often touted as a hair growth miracle, has little scientific evidence to support this notion; that said, biotin has been shown to add hydration to dry hair, leaving it bouncy, shiny, and soft. Moreover, dermatologist Dr. Nicole Ruth, MD, previously told InStyle that it generally “improve[s] the health of existing strands.”

Fans of Viviscal’s $9 formula are shocked by its efficacy and the speed at which it delivers visible results. “I have been dealing with fine, thin hair for years,” said one reviewer; “After the first shampoo, my hair felt and looked thicker,” they reported, noting newfound “body and shine.” Another fan quipped, “my thin hair is now stronger than my Wi-Fi signal,” adding it’s “fuller, bouncier, and honestly just happier” since starting to use the $9 formula. Yet another shopper, who’d struggled with “bald patches” prior to trying Viviscal’s formula, said the shampoo works quickly. It triggered new growth around their hairline for a “thicker” mane. 

For longer hair and an instantly thicker-looking mane, shop the strengthening shampoo fans swear by. The Vivisal Thickening Shampoo is now on sale at Amazon for Prime Day. Consider similar plumping formulas, below.
