Shoppers Say This $7 “Magic” Thickening Shampoo Gives Fine Hair “Ultimate Volume”

While strand-strengthening serums and dermatologist-recommended hair vitamins can work wonders to promote fuller, healthier hair, visible results require patience; most require months of consistent use before results become apparent. While, of course, these products are absolutely worth considering if you’re seeking long-term hair improvement, incorporating volumizing shampoo into your hair-washing repertoire can create fuller-looking hair much more speedily — and often, after just a single use.

One such shampoo, the John Frieda Volume Lift Lightweight Shampoo, boasts over 4,000 five-star ratings from Amazon shoppers who gush over the formula’s instant pick-me-up for fine, flat hair. Best of all, it’s a mere $7 at Amazon — but only for a limited time.

The John Frieda Volume Lift Lightweight Shampoo is a root-boosting hair cleanser that adds instant thickness and fullness to fine, thin, or flat hair. The color-safe formula is gentle enough for daily use, and delivers noticeable fullness after a single wash.

In addition to ample volume, the shampoo imparts glossy, light-reflecting shine, thanks in part to aloe vera — a plant extract known in the skincare world for its hydrating prowess. As trichologist Dr. Isfahan Chambers-Harris previously confirmed with InStyle, the ingredient also works wonders on hair of all types and textures. For one, aloe “lower[s] the pH of the hair to the ideal range… which helps to seal the cuticles, leaving hair moisturized [and] shiny.” Furthermore, "aloe vera contains essential amino and fatty acids, which help to strengthen hair,” dermatologist Dr. Jeriel Weitz, M.D., previously shared with InStyle.

Shoppers are “shocked” by how their strands glisten after using John Frieda’s shampoo. Reviewers are equally impressed by the formula’s instant root-lifting, strand-plumping volume. For instance, one shopper, whose hair had become limp after using weighty color-protecting products, John Frieda’s shampoo works “like magic,” to instill “full, happy hair,” and works to protect color. According to another reviewer, who uses the shampoo daily, it leaves hair looking healthy, shiny, and full; it delivers “ultimate volume,” they note, that lasts throughout the day. Similarly, another fan shares their hair is voluminous “for two days” post-wash. Finally, another fan, whose hair is naturally “baby-fine,” notes how the shampoo “lifts” strands, “gives body,” and makes hair look “more dense” after a single use.

For fuller, thicker-looking hair with a side of healthy, glossy shine — both apparent after a single in-shower use — shop the John Frieda Volume Lift Lightweight Shampoo at Amazon, where it’s $7 for a limited time. To complete your routine, check out the corresponding conditioner, also on sale.
