A client sat in my chair last week, ran her hands through her fine, color-treated hair, and said the thing we hear almost every day at Sølvi: "It looks great when I leave, then it falls flat by lunch." So let's talk honestly about one of the products we reach for most often behind the chair, the Volume Boosting Mousse from Davines. Is it actually worth $37, or is it just another can of foam? Here is our straight answer.
What it is and who it is built for
This is a volume system made for fine, flat, or lifeless hair. If your hair has plenty of strands but no body, if it goes limp a few hours after you style it, this is the category of product designed for you. It builds lift and movement at the root without leaving a heavy, crunchy residue behind. That last part matters more than people think. A lot of volumizers add body but leave your hair feeling coated and stiff. This one keeps things soft while still giving you height.
It is also safe for color-treated hair, which is a big deal in our studio. A large share of our fine-haired clients are also coloring, and the last thing we want is a styling product that fights the work we just did at the bowl.
How we actually use it
We keep this simple. Shampoo and condition as you normally would, then work a small amount into damp hair, concentrating at the roots, before you blow-dry. The lift comes alive with the heat and airflow of drying, so the blow-dry is not optional if you want the full effect. A common mistake is using too much. Start with less than you think, because fine hair gets weighed down fast.
If you want to see this done on your own head before you commit, our stylists are happy to walk you through it at the end of an appointment. You can see our full menu on our services page.
The honest drawback
Here is where the "worth it" question gets real. This mousse rewards effort. It needs a blow-dry to deliver, so if you are someone who washes at night and goes to bed with wet hair, or you skip heat styling entirely, you will not get much from it. The lift mostly happens during drying. Air-dry it and you are leaving the best part on the table.
It is also not the product for thick or coarse hair. If your hair is already dense and heavy, a root volumizer like this is not going to move the needle, and you would do better with a different styling approach. We tell clients this honestly rather than sell them something that will sit in their cabinet. A $37 can is a fair price for fine hair that needs help, but only if the formula matches what your hair actually is.
Why it earns its spot in Boise
Boise is dry. Our air pulls moisture out of hair fast, and for fine hair that often means two problems at once, flat roots plus static and flyaways. A good mousse helps on the body front without adding the kind of weight that kills the lift you are chasing. We have clients who walk in from the wind off the foothills with hair stuck flat to their heads, and a small amount of this worked in at the roots gives them back some shape.
That said, dry climate is also why we pair it with the right moisture routine. Volume at the root is great, but fine hair in Idaho still needs hydration through the mid-lengths and ends, or you trade flat hair for frizzy hair. We are happy to map that out for you in the studio at 104 S Capitol Blvd in downtown Boise.
Our honest verdict
If you have fine, flat hair, you blow-dry at least some of the time, and you want soft body that lasts through the day, yes, this is worth it. It does the one job it promises and it does it without making your hair feel coated. If your hair is thick or coarse, or you never reach for a blow-dryer, save your money and ask us about something that fits your routine better.
The truth is the best product is the one that matches your hair and your habits, not the one with the loudest label. If you are not sure whether this is right for you, bring it up at your next visit. You can book an appointment online, and we will tell you the truth about what your hair needs, even if that means talking you out of a purchase.
