John Frieda ULTRAfiller+ Thickening Spray, Thickening & Strengthening Spray for Damaged or Thin Hair, Infused with Biotin and Hyaluronic Acid to Strengthen Hair for Thicker Fuller Results, 5 Oz

I think this works quite well. I do not have prior product knowledge to compare this too, have noticed some say it doesn’t work as well & has a funky smell but I think it works fine. It also smells good too. Maybe some got an old outdated batch or possibly theirs had been stored improperly in high heat? I’m a former stylist so I have used my fair share of products over the years. I’ve gotten used long ago to using different products for different things, like this product for example provides a decent thickening effect but not much hold so I use a spray gel, mousse or something w/hold with it. I also use a leave in conditioner as I have curly semi frizzy hair that is not super thick. I think the additional products also help add texture to my hair. As with everything it will react differently on everyone so try to base your decisions of reviews from people who have hair like yours. I would say this would be a good product for anyone with thin hair regardless if it is straight or curly & the diameter of each piece of hair is fine to regular.

I have thin hair and I finally found a product that works! It gives volume without a heavy, dull look or feeling. It looks fuller & feels silky, not oily or greasy feeling. Love, love, love the results! The best part is that it doesn't take a lot to get great results. I'm hooked! Apply it per directions, let hair air dry till it's just slightly damp and then blow dry for great results!

I have been using the shampoo and conditioner along with this spray. My hair is very thin and fine. This spray works well as do the other products. My concern was that the products would actually weigh my hair down, but they didn't. This spray filler works very well by adding volume and holding my hair in place. It does not cause any problems with my scalp like some I have used. I haven't used it long enough to know if it will help with hair growth, but my hair no longer has split ends, it feels soft, and the loss of hair appears to have lessened.The only reason I downgraded the spray by one star, is because I have a lot of trouble pushing the pump apparatus so I can easily apply the spray. This is related to my arthritic fingers, so if one does not have any arthritis there should not be a problem.

I like the way it makes my hair feel fuller, but the next day it feels a bit greasy.... ok to use occasionally

This stuff really works. I was skeptical because I have used so many other products that did not do much for my fine, thin hair. I love this and just ordered 2 more bottles. It created volume at the top and crown of my hair. I actually amazed at the difference it made. My hair is also less frizzy. It is soft and not sticky. I'm going to tell my hair stylist about this wonderful product. If you have been considering trying it, don't hesitate. You will love it.

Omg I love this stuff ! I wasn't going to buy it at first because I really didn't think it would do much good . My hair is fine and very straight and thin . In addition , I'm going through menopause which has caused my hair to become as dry as the desert 🏜. But I saw all of this positive reviews , so I decided to give this product a try . It's amazing! It really does what it says ! My hair looks so much fuller ! And it has so much body and some wave . My hair is normally poker straight. I'm going to continue buying this product for sure !

Highly recommend using this with the other products from this line. Works exactly as described.

I have very thin and fine hair. This product makes my hair look fuller and thicker. I love it.
