The hardest correction work we take at Fluff isn’t colour. It’s extensions. Clients come in with tape-ins sliding out at the roots, hand-tied wefts sewn into damaged hair that’s shedding by the handful, I-tips placed too dense at the nape and giving someone a constant headache. Every one of those jobs was installed by a licensed stylist. Extensions aren’t a separate license in Colorado, which means anyone who passed cosmetology school is technically allowed to put them in your head.
That’s why “certified” matters. Specific extension methods have specific manufacturer-level trainings attached to them, and the stylists who’ve put the hours in know what a scalp looks like before it’s about to break down, how to place for density without overload, and how to take extensions out without ripping the underlying hair with them. This is what to look for in a Denver extensions stylist, how Fluff trains for it, and what questions to ask anyone before you book an install.
The honest version
A licensed stylist isn’t the same as a trained extensions stylist. The difference shows up six months later, when the install is either still holding or ruining your hair.
Why certification matters more than a license
Colorado licenses cosmetologists to cut, colour, and style hair. The board does not separately license extensions, and cosmetology school covers hair extensions in a handful of hours at most. Most stylists who install extensions learned the method from a manufacturer’s class after school, through on-the-job shadowing, or from watching other stylists. The quality of that training varies wildly.
Certification from a specific extension brand means the stylist has gone through a multi-day, hands-on training, passed a practical exam, and is authorized to buy that brand’s hair. It also means they’ve been taught the brand’s specific placement pattern, the correct bead size for the client’s hair density, how to tension the installation so it doesn’t torque on the scalp, and how to remove the extensions without cutting the natural hair shaft.
The three methods we run at Fluff (hand-tied wefts, I-tips, and tape-ins) each have their own certifying education. A stylist certified in tape-ins is not automatically qualified to do hand-tied wefts. When you’re booking, the question isn’t “are you licensed?” because in Colorado nearly every stylist will be. The question is “what brand and method are you certified in, and how many installs have you done on real clients?”
What a bad install actually costs you
The worst we’ve seen: a client who came in three months after a hand-tied install at another salon with visible traction alopecia along her part line, the underlying hair snapped to about an inch where the bead rows sat, and scarring at two anchor points. She’d paid $2,100 for the install. Correcting it took us four appointments, a year of at-home recovery, and she still has a thinned zone around her hairline that may never grow back fully.
That’s the extreme end. The more common bad-install cost is smaller but still meaningful: extensions sliding out at six weeks because the beads were sized wrong, constant scalp irritation from over-tensioned wefts, and hair that’s visibly thinner every time the extensions come out. Most clients we see for correction don’t realise their install was the problem until they’ve already lost a fair amount of density.
There’s also the financial cost. The cheapest extension install in Denver starts around $400, and that’s almost always a stylist who hasn’t gone through certified training. The hair itself is usually lower quality, too, which means you’re re-buying within six months instead of getting eighteen months out of a proper install. A certified install costs more up front (at Fluff, full installs start around $1,600 and go up based on method and fullness) and lasts longer, which makes it cheaper per month of wear.
How our extensions team trains at Fluff
Every extensions stylist at Fluff is certified in the specific method they install. Our hand-tied wefts stylists are certified in Beauvoir’s hand-tied system, our I-tip stylists are certified on the micro-bead methodology, and our tape-in stylists are certified through Beauvoir’s tape-in education. Those certifications aren’t a one-time class; each one is refreshed as techniques evolve, and our team sits in advanced education sessions at least twice a year.
Beyond the brand-level certifications, we have an in-house apprenticeship. New stylists at Fluff who want to add extensions to their service menu shadow installs, assist on consultations, and do supervised practice installs on our models before they ever touch a paying client’s hair. That’s a process that takes months, not weeks, and it’s why we limit how many stylists on our team actively install extensions at any given moment.
The other piece nobody talks about: colour integration. Most extensions clients also want colour services, and the two need to be coordinated so the install blends. At Fluff our extensions stylists are also colourists, which means one person is deciding how the base colour, the hand-painted pieces, and the extension hair will all read together. When those two jobs are split across two salons, the colour almost never matches, and the blend reads as extensions rather than as hair.
Different methods, different certifications
A stylist trained in one method is not automatically qualified to install another. Here’s what each one asks for.
Hand-tied wefts
What the stylist needs to know
Bead sizing for scalp density, correct weft tension, anchor placement that avoids pressure points, and sewn-in attachment without over-torquing. Certification: typically two to three days of hands-on brand education.
I-tips
What the stylist needs to know
Precise strand selection, consistent bead tension, diagonal pattern placement so the grid isn’t visible when hair parts, and move-up cadence every six to eight weeks. Certification: typically a full day of bead-and-strand practical.
Tape-ins
What the stylist needs to know
Clean adhesive application, proper sandwich alignment for no visible tape, removal technique that doesn’t tear the hair shaft, and reuse protocol since tape-ins are re-taped and re-installed. Certification: typically a full day of install and removal.
What a real extensions consultation looks like
A proper extensions consultation at Fluff is 45 minutes to an hour and costs nothing. We do it in person at the salon, not over Instagram DM. That time is for us to look at your scalp and underlying hair density, talk through your lifestyle (workouts, swim, how you sleep, how much you travel), understand what you actually want the extensions to do for you, and then honestly recommend the right method (or tell you extensions aren’t the right solution right now).
A consultation should always include a density check. We part the hair in multiple zones, look at the scalp, check for any existing breakage or thinning, and feel the hair for porosity and texture. If a “consultation” is really just looking at a colour swatch and picking a weft count, you’re not getting the due diligence that makes an install last. A stylist who’s willing to install on a client without that due diligence is not a stylist we’d recommend.
We also walk through the at-home maintenance piece, because that determines whether the install actually lasts. What shampoo you’ll use, how to brush with wefts in, how to sleep, whether a silk pillowcase or a loose braid is better for your install, and when to book move-ups. Clients who get that education up front get eighteen months out of their hair. Clients who don’t, tend to blame the salon six months later when the install is already done.
Before you book
Six questions to ask any extensions salon
1. What method and brand are you certified in? A good answer names a specific brand and a specific method. A vague “I’ve been doing extensions for years” is not an answer.
2. How many installs have you done, and can I see photos from the last six months? Recent work matters more than a three-year-old portfolio. Techniques change.
3. Do you do a density check before booking? The answer should be yes, and it should happen in person.
4. What’s your move-up cadence and what does it cost? If they don’t have a clear move-up schedule, or if the move-up fee isn’t itemised, ask why.
5. Who sources the hair, and where does it come from? Brand-certified stylists buy through authorized channels. If the hair is coming from a marketplace or a mystery vendor, reconsider.
6. What happens if I want them removed? A certified stylist will walk through removal protocol and cost the same way they’d walk through install. A vague answer here is a red flag.
Questions clients ask us about extensions stylists
Is there a state license specifically for hair extensions in Colorado?
No. Colorado licenses cosmetologists, and extensions fall under the general cosmetology license. That means anyone with a cosmetology license can technically install extensions without any extensions-specific training. Certification is issued by the extension manufacturers themselves, which is why asking about brand and method certifications matters more than asking about licensing.
How much do certified extensions cost at Fluff?
Full installs start around $1,600 and move up based on method, length, and fullness. Hand-tied wefts typically run $1,800 to $2,400 for a full install, I-tips run $1,600 to $2,200, and tape-ins start around $900 for a starter set. Move-up appointments are billed separately and run $250 to $450 depending on method.
Can I trust a stylist who only shows me results on Instagram?
Instagram is the showcase, not the qualification. The photos tell you what their best-day work looks like, under lighting they control. Before you book, ask for an in-person consultation, look at the scalp-level placement in the photos (not just the finished hair), and ask how long each of those installs has been in. Six weeks of wear reveals more than the install-day photo.
What if I already have extensions installed somewhere else, badly?
Come in for a consultation. We’ll assess what’s in, how it was installed, and what the underlying hair looks like. In most cases the safest path is full removal followed by a recovery period before re-installing. If the damage is minor we can sometimes remove and re-install on the same day, but we never promise that sight unseen.
Do I have to be a regular Fluff client to book extensions?
No. We take new extensions clients regularly. Most of our extensions clients also move their colour services to Fluff over time because the extension-plus-colour integration is where the real quality difference shows up, but that’s a decision you make after you see the work, not a requirement up front.
Book an honest consultation with a certified stylist
Consultations are free and take about 45 minutes in LoDo. We’ll do a density check, talk through lifestyle, recommend (or not recommend) the right method, and quote you before you commit.
