ULTRAfiller+ Thickening Shampoo, Strengthening Shampoo for Damaged or Thin Hair, Infused with Biotin and Hyaluronic Acid to Strengthen Hair for Thicker Fuller Results, 8.3 Oz

Woah, magic shampoo. I bought this after reading that it won the 2025 Allure Best Voluming Shampoo. I have been battling fine hair my entire life, and I can hands down say that this is the first shampoo that I've ever tried that feels actually thickening, ON IT'S OWN, without seven other products. I'm still trying to figure out how they do it. I got a compliment on my hair at work on my first day - what?! My hair looks full and healthy, has smooth and easy combing, and a very very light clean smell. Incredible value for the money. Well done formulation team! 👏

This product really works! My hair had been thinning and I tried other products before this one. My hair feels and is noticeably thicker.

Great shampoo, I have thing hair and has helped me lots! Will buy it again!

Alright, I didn’t expect much but I’m pretty impressed. I have very fine curly hair prone to breakage; lately I’ve been worried about thinning around my part and hairline. This product is cheap enough that I figured, why not try it?I’ve used this and the conditioner for a few days now, along with my usual curl cream and blow dryer. I wish I’d taken before photos - maybe I’ll upload pics of a day I don’t use it vs when I do. My part and hairline are much less noticeable, my hair has more volume with less frizz, and my curls are more defined. I don’t lose as much hair in the shower.It doesn’t promise to be a permanent solution but it really does work after one use, so it helps while searching for a longterm treatment. Pretty cheap compared to most specialized hair products.One star off because I hate the smell. Kind of a medical scent - reminds me of Head & Shoulders maybe? But the smell washes out, the conditioner has a lighter/better scent, and my curl cream covers both.

The shampoo really adds volume… Very pleased!

Love this product and can definitely tell a difference in my thin menopausal aged hair. Scent is subtle but delightful, instantly feel your hair thicken while washing, doesn’t take a lot at all each wash, lasts. Has a companion conditioner but for some reason the conditioner smells a little different. Great option for thickening your hair with out a lot of product. Makes hair soft and smoother, not greasy at all. I have color treated hair and it’s fine with that, no issue.

Not really satisfied with the product does not give volume, but does smell good.

It took a second attempt, but I received a wonderful piece! It is elegant and truly a work of art. Thanks to the glossy white finish on the back, this dish pairs beautifully with fine porcelain. And it is pleasantly lightweight! Absolutely delightful!
