Truly Makes Hair Look Thicker
Read my review on shampoo & conditioner. This works great when used with both. You have to blow dry to get hair to appear thicker, which it does a great job of. I was very impressed by how much it looked thicker, but if I don't blow dry as directions say, I only notice a small difference. Leaves hair coarse, but I have fine hair and the coarseness is what makes it look thicker. Hair is not as shiny but I am told they sell a spray for shine which I have yet to try. It smells nice. It doesn't leave hair greasy or sticky. It does a great job of making hair look thicker, as long as you blow dry it. I would recommend, though I don't think I would use it every day as blow drying can cause more hair loss.

Love it!
I don't know how it works, but it does. It's kind-of like using a stiff hair spray, but different. Better in terms of making my hair look not so thin. I used to have thick, wavy, healthy hair. But stressful and traumatic events have always caused me to lose hair. Some of it always grows back. After a year or two I'll feel the hairs growing in. This last time, the event was drawn out alot longer, and I've lost alot more hair. Its been 6 years and I'm still losing hair. I haven't noticed any hair growing in yet ... But I'm working on it! Meanwhile, this product helps me not stress out about losing my hair!

Good Product
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 guess it works
I guess this works somewhat …. but makes my hair feel like straw. I wish they would make a thickening product that didnt make your hair feel like there is glue on it. Sigh …..

Fantastic product for fine hair
I have lots of very fine hair that does not get full/volume no matter what I've done or used. This lightweight spray onto my roots and then worked throughout is amazing. Blow dried with round brush and hair was full and lasted all day. Highly recommend to give very fine hair volume and thickness. No scent noted.

Perfect for my fine thinning hair!
I washed my hair yesterday and it’s still clean this morning . The top however was soft and flat. I wet just the top to try this product for the first time. I didn’t have much hope to be honest aa my hair is thinning and fine and hadn’t been freshly washed though clean. Let me tell you!! Buy this! My hair looked so thick on top and wasn’t sticky or gunky or dry! My hair curled great with the flat iron and I pulled the back up. It looks like I just shampooed my hair and fixed it and ita got the full was I want! I’m so happy that I found this product. It’s lightweight and the scent is light and clean. My hair feels amazing and looks great. This will be my go to from now on. No more mousse. I wish the bottle was a little bigger for the price but it works and I’m worth it.

Did absolutely ZERO to make my hair more volumized
I have a lot of hair...the problem is, it's super fine and thin. I always need a volumizing product to feel like I actually have a decent amount of hair. My normal go-to product is hard to find for some reason, so I thought I would try this as it's readily available here. What a disappointment!! I used a medium amount of product and found absolutely zero difference in my hair once dried. The next day, I used a greater amount of product - thinking I hadn't used enough. I mean, I really used a lot. Zero, zilch, nada. My hair felt no different. How on earth this product has gotten so many good reviews is a head scratcher for sure. Frustratingly, it's not returnable so I'm stuck with this $10.97 bottle that doesn't work on my hair.

Great Product
This is really a great product. I do I notice a difference in thickness and it's the perfect product for conditioning my ends and calming the static I contend with in the winter months too.

Mi pelo es demasiado delgado, escaso y rizado, un cabello muy difícil, este es el único producto que realmente ha hecho una diferencia usándolo de acuerdo a lo que indica el empaque, mi cabello se ve con cuerpo, sin frizz, ya no se abomba, por fin puedo alaciarlo sin que se haga como algodón de azúcar, realmente es con lo único que he visto una diferencia real
