You may have already heard this complaint: My eyebrows just don't grow. I've made some progress thanks to brow growth serums, but the difference is small -- some wispy hairs that are better than nothing don't do much to make my brows look more substantial overall.

Fortunately, I have a solid brow powder routine, which makes a big difference -- though definitely not a Delevingne-level difference.

Even on their best day, my eyebrows are not doing me any favors. So when I heard that Courtney Buhler, the founder of Sugar Lash eyebrow and eyelash extensions, was going to be in town, I jumped at the chance to meet her for a brow-over.

Buhler tells me I'm the perfect candidate for eyebrow extensions: I already have a good eyebrow shape, but I have a few holes that need to be filled in, and my arches are too skinny.

After she cleans and exfoliates my brows (artificial brow hairs will fall off along with any dry or dead skin, so you want to start with a smooth surface), Buhler uses a brow pencil to outline where my new brows will be. Even though I look like Groucho Marx, I'm tempted to ask her to go bigger. (I resist. I want the change to be noticeable, but not too noticeable.)

Sugar Lash brow extensions come in a variety of colors and textures, and Buhler chooses a straight brown hair to match what I've already got. She explains that she's going to apply the individual hairs two ways: glued to my existing brow hairs and glued directly to the skin around my brows using surgical glue. The hair glued to my brow hair should last two to three weeks while the hair glued to skin only lasts about five to seven days.

After a mere 45 minutes (we chat and listen to Coldplay, and I don't feel anything while the brows are being attached), my eyebrows are finished. I look in the mirror, and I'm ecstatic: These are my dream brows. I squeal, I hug my new best friend Courtney, and then I immediately begin grilling her about aftercare so I can make my amazing eyebrows last as long as possible.

On my way back to the office, I text a selfie, the words "brow extensions!" and a dozen smiley face emojis to every one of my friends. The reviews are unanimously positive.

I'm supposed to avoid my brows as much as possible. Don't touch them. Don't powder them in. And definitely don't comb them.

That night, I very gently wash my brows with Sugar Lash LashPure Eyelid Cleanser, $15, (a special cleanser that doesn't interfere with the glue), and I don't go anywhere near them when I wash the rest of my face.

I have trouble falling asleep because Buhler says my pillow is eyebrow extension Enemy No. 1. The goal is to keep the brows from touching the pillow -- not the easiest ask.
