Not a fan - expensive, doesn't live up to it's description, makes hair greasy. Expected alot more for what I paid.

I use this in my damp hair before I blow dry my wavy hair straight. I heat style my hair a lot and the ends tend to get a little frazzled so I also will apply this on dry hair on the ends and throughout for added shine and to smooth the ends down. This product is great for adding shine to your hair and for keeping my blow out to look sleeker. Gotta be careful how much you use though...it is kinda oily and too much will make your hair look ick. Two pumps on damp hair, and 1 pump on dry hair is just the right amount.

I've been using this to weigh my fine hair down at the ends and to add shine. It usually does both pretty well. I use two squirts for my shoulder length hair. On dry winter days; however, this isn't enough. The air just sucks the moisture out of my hair and the ends get that flyaway look. This winter, I am using a combo of this fluid and a styling cream on the ends.

I love this. Have had the same bottle for a year now and looking forward to another year, maybe 2, of shiny, herbal smelling hair. It's actually an amazing value for how much you get considering a bottle could last you 2 or 3 years. It's perfect for smoothing but not weighing down, exactly what it says it does. Like most Aveda products, i'm in love with the smell of this. Lavender with a touch of bergamont. Aveda is my favorite hair care line, I wish I could afford to use all of thier products!

I use this as sort of a smoothing serum once my hair is dry/styled. Works well to keep frizzies away and gives my hair a nice healthy shine. Replaced my matrix serum with this. Will definitely repurcahse.

Does everything for softness and nothing for shine. Used as a leave in while my hair was damp and then blow dried. My hair was EXTREMELY soft but lacked the shine that I was expecting with using a serum. Applied a little more after blow drying and still not much shine. Next day - hair was still soooo soft but lacked the shine...I have dark hair so it doesn't take much for shine to show up on my hair. Overall, pretty good product, smells good but the scent quickly disappates, I like the pump applicatior, the price is expensive for a serum but I've paid more. I will keep this product for use as a leave-in on damp hair but will not repurchase once this bottle runs out.

I really like this product, but I can see why it doesn't work for everyone.
My hair is fine and wavy, relatively long and I have a lot of it. I wash and blow it dry every other day to straighten it, and use three pumps of the smoothing fluid while my hair is still damp prior to blowing it dry. It smooths my hair and keeps it straight and shiny, and is light enough that I don't need to wash it out every day. Having used many other products (John Frieda, Body Shop, Redken, Shiseido) that promised to do the same and didn't deliver for me, I am ecstatic to have finallllllly found something that does. In spades!
While on vacation, however, I decided to skip blowing my hair out and let it dry wavy in the breeze. I applied my usual three pumps, brushed it through and headed out. When I got back to my room, though, my hair was a limp and frizzy mess...so I pulled out the smoothing fluid and tried adding an additional two pumps to my dry hair. It looked...oily. The frizz was a little less frizzy, but overall I looked like I needed a wash in the worst way. Not pretty.
So used as a styling aid this stuff is golden: it gives me my best-ever hair. But if you need a quick-fix to perfect your messy hair before you run out the door...keep looking. And when you find that elusive gem, let us all know!

I have long black shiny thick hair. I got this to smooth the baby hairs that likes to stick out hear and there, but I should probably use hairspray instead of the smoothing fluid. The packaging is misleading as the fluid doesn't actually "spray" out of the bottle; it oozes out of the bottle and flows to wherever gravity decides to take it. It is light weight and I can imagine it giving other people the shine factor, but for me it was a redundant shine product that I didn't need. I would not buy this again, but it's a good product that I would recommend to others.

This serum works great for my coarse asian hair to make it smooth and shiny. Also love that's that not that greasy like the Brillant serum. I've used it for several years and love it. Wish they would make a travel size so I can take it on the road with me.

Nice light shine serum. Smells good and does a great job attacking frizz and adding shine. Would I buy again? No, lots more fish in the sea to try.

I adore this product. I have very fine hair with a little frizz and some fly-aways.
How I use it:
I apply one pump to damp hair starting halfway down my hair and through to the ends. I then apply Bumble & Bumble Does It All spray and dry my hair with a hot-air brush.
Pros
- Doesn't weigh my fine hair down at all
- Greatly reduces number of fly-aways and frizz
- My hair feels soft and smooth - like I've just been to the hair salon
- Hair looks shinier
Cons
- Price continued >>

I really love this stuff for taming fly aways and eliminating frizzies. Works great but go light on the amount of product b/c you can look greasy if you use too much.

I have been using this product for a couple of years and love it. It is a little pricey, but a little amount goes a long way as it's quite concentrated. Plus the pump dispenser makes it super user friendly. I normally use this after flat ironing. It gives really nice shine, reduces fly aways and frizz. My hair feels smooth and silky, never greasy or limp. A worth while investment that I adore using.

I have been using this for over 5 years. I love it...I loved it more so in the first few years than now, because I think mine might actually be going bad finally.
The price is steep. That being said, it lasts FOREVER. I have been using the SAME bottle twice a week for 5 years now and I still have almost HALF of it left. I love the shine and bounce this gives me. No, it doesn't make your hair suuuuper shiny, but shiny enough to make a noticeable difference. And you only need the tiniest amount (I only use 1-2 squirts on my thick, shoulder length hair).
One lippy off for the fact that, despite using this right after I wash my hair, it still fluffs up a lot and appears dry for the first several hours. It doesn't matter if I put it in while it's damp, after it's dry or in conjunction with the flat iron--it still fluffs up. The next day though, it's gorgeous.
My verdict: buy it if you don't have fluff issues. It'll give you shine and bounce.

Edit November 2010: I now use Marc Anthony Moisture Gloss Drops, non-greasy, doesn't break me out, and the best part - under $10 at your local drugstore...:) I have used this product for many years, and couldn't be without it. If you have fine hair that is easily weighed down by greasy products, give this a try. I use this after straightening my hair, on my ends and face framing layers to smooth out any frizzies. You only need a very small amount, I use 2 pumps for my shouder length hair. I also use it when I want to slick my hair back into a low pontail prior to finishing with a shine spray. It is expensive - around $30 cdn. for 3.4 fl oz. or 100ml, but a little goes a long way. FYI: I have never had ANY breakouts on my scalp from this product.

This is my fav to use after flat ironing. It gives really nice shine, reduces flyaways & maybe a bit of frizz. I think that is its intended use. Don't expect miracles from this one. It's not gonna take you from a poofy frizz-ball to flat, smooth & silky in 1 step. But to use after flat ironing (to reduce the last bit of frizz &/or flyaways), it works nicely & it has a really nice scent. I thought this was meant to be used by those w/fine hair only, but I have thick coarse hair & it works great for me. It's very, very pricey, but it works so well & it'll last a long time so it's absolutely worth it. continued >>

I love this. I have fine long straight hair with lots of flyaways. Any sort of smoother I have used in the past always makes my hair look greasy-no more flyaway-but greasy. This is the one and only thing that actually works and doesnt weigh my hair down. I rub 2 pumps through wet hair before I blow dry, then i use 1 pump on my dry hair for even more shiny glossy smoothness. I love this so much!

A definite MUST have, at least for me. I usually put it on my hair dry, after styling to make the fuzz and flyaways tame down -- and it works!! If you use the right amount, it does not make the hair look greasy - just shiny and healthy. If I don't have this in my hair, my hair is sooo flyaway! I use it probably 4 times a week but because it takes such a tiny amount ( a dot only), it lasts forever! I've had mine a year and STILL have half a bottle :)

This stuff is wonderful. Makes the ends of your hair look like you just got a haircut. Smells great with a light citrus scent, and I can use it or dry or wet hair. Much better than hang straight for me, as that was a bit heavy. FYI, I have scads of fine, wavy/curly, highlighted hair. When I use this, my hair feels and looks like glass.

Wonderful product!
A little goes a long way, one or two pumps right before I flat iron. I am on my second bottle.
Love, love, love this product!
