Shoppers Swear By This Thickening Shampoo That Adds ‘Substantial Fullness’ to Thin Hair

Thickening shampoos are the perfect solution for those who want to add instant volume to their thin hair because let’s be real—using rollers or heat styling won’t last past a day (sometimes even hours).

More than 1,000 Amazon shoppers swear by it, plus over 3,000 people have bought it in the last month, making it definitely worth checking out.

This rejuvenating treatment is formulated specifically for thin or fine hair as it cleanses while also strengthening strands thanks to its hero ingredient: biotin. While research is still limited on its effectiveness for hair growth, biotin is still an essential nutrient for skin, hair, and nail health. As a result, it reduces split ends and breakage to enhance the hair’s fullness. 

And the nourishment doesn’t just stop there — it adds softness and smoothness for a weightless feel. Moreover, this formula also contains zinc PCA that purifies the scalp from oiliness, buildup, and more to further promote healthier hair. For the best results, though, apply the conditioner and leave-in spray for a thicker-looking mane.

Many reviewers swear by the Full Density Thickening Shampoo for improving their hair’s appearance. A shopper who said it “changed [their] hair completely,” so much that it “grows faster and is more voluminous.” A second customer shared, “It added substantial fullness to my fine and thinning hair with the first wash.” Other users noted that it leaves their hair “full and luscious,” as well as “light and fluffy.”

If your hair seriously lacks volume, try this hair-boosting formula at Amazon today. Shop Biolage’s Full Density Thickening Shampoo for $24, as well as these similar treatments, below.
