Now that the holidays are over, we can all take a collective sigh of relief. The weeks leading up to the new year are undoubtedly stressful, and all that stress can definitely take a toll on our bodies. In fact, stress is one the leading causes of hair loss, which is a personal beauty woe I’m determined to tackle in 2025.

If you’re also looking to achieve a fuller, thicker mane this season, you may want to consider trying the RootStim Biotin and Rosemary Hair Growth Shampoo, which is on sale for only $18. While there’s a ridiculous number of hair growth products on the market, plenty of Amazon shoppers have seen incredible—and speedy—results thanks to this discounted find.

Unsurprisingly, this shopper-loved pick contains both biotin and rosemary, two ingredients experts swear by for hair health. Biotin prevents breakage and improves shine, while rosemary can improve scalp circulation and contains antimicrobial properties. Not to mention, the shampoo also has aloe vera, which can alleviate scalp itchiness, and ginger root, which strengthens hair stands.

I never make any beauty purchases without checking the reviews first, and the feedback customers left on this product certainly has me sold. After using the shampoo for only a few weeks, one shopper said their hair felt “fuller and healthier,” adding that the product’s ingredients “work wonders for stimulating growth.” A second reviewer reported that they’ve noticed “lots of new baby hairs” after using the product, while a frequent buyer of hair loss shampoos declared this is “by far the best” one they’ve tried, given that their hair is “noticeably thicker and fuller now.”

Aside from new growth, fans of the product are experiencing other benefits as well. One shopper noted their hair was “super soft” after use, while someone else mentioned their hair now has a “fresh, clean scent” and a “healthy” feeling scalp.
