PILLOW TALKS & ESPRESSO SHOTS SERVED WEEKLY

The Hair Serum I Was Ready to Hate but Kept Reaching For

Yes, next on the chopping block we’ve got the Kérastase Genesis drops. The claims? Anti-fallout, scalp-conditioning, and magical hair-saving elixir, apparently. It’s got all the buzzwords: Aminexil, caffeine, arginine and as a fake blonde (who was technically blonde as a toddler), I was instantly intrigued. 

Now, I baby my hair. Like… satin pillowcase, low ponytail, we don’t skip-trims baby. So when a brand says they can prevent fallout and restore moisture to the scalp, my credit card gets twitchy.

Cue the experiment.

The Setup

I gave these drops a proper three-month run. Clean scalp, no distractions. Just this serum post-shower, applied in sections. I wanted results. Not placebo, not “maybe it’s working?” delusion. Real. Results.

The Results

Week One: Honestly? Meh. Smells nice. Absorbs well. No greasy residue. But I wasn’t ready to sing its praises just yet.

Week Four: My part line wasn’t looking quite so… betrayed. Less visible scalp. My ponytail didn’t feel thicker, but it looked like it had more shine.

Week Eight: This is where it clicked. I wore my navy coat to work, and when I stood up from my sad little cubicle chair, I saw hair. Stragglers. Everywhere. Instant heart drop. My anxiety said “Oh dear God, you’re dying.” Then I remembered: I’d run out of the serum. Hadn’t restocked in weeks.

Crisis solved. Cart repurchased.

The Real Talk

Did I want this one to flop because of the price tag? Absolutely. But did it win me over and earn a permanent spot in my routine? Yes. She’s subtle, she’s silent, but the second you stop using her — your coat, your brush, and your shower drain will notice.

Glow Lab Verdict

Would I keep using it? Yes, and I already have. My hair feels stronger, looks healthier, and I notice when I stop. It doesn’t need a sales pitch. It earns its place.
