Day 1: First Impressions
Okay, it arrived. The box was one of those flimsy bubble mailers and the corner was pretty squished, but the bottle inside was fine. Glass, which felt more substantial than I expected. It’s a small bottle, 30ml, with a brown glass dropper that has measurements on the side. Honestly, it looks exactly like what you’d get in a pharmacy. There’s a slight chemical-ish smell, nothing strong or perfumed, which I guess is a good sign? It’s not exactly off-putting, just smells… clinical. First application was weird. The serum itself is thin and clear. I put a dropper full on my scalp where my hairline is starting to look a bit too friendly with my forehead and gently massaged it in. It dried down pretty fast, wasn’t greasy at all. My hair didn’t feel gunky or heavy, which was a major plus. That was about the only plus I felt on day one. The whole thing felt like committing to a weird, long-term science experiment. I ordered Chinese food to celebrate starting this journey, if you can call it that.
Week 1: The Adjustment Phase
So about a week in, and my main impression is: dryness. My scalp got flaky. It wasn’t major irritation or itching, just noticeable white flakes especially around the application area. I was grumpy about it. I also learned that you absolutely must apply this to a completely dry scalp. I rushed it once after my shower and it felt like it just sat on top of my skin, took forever to absorb, and I swear it made the flaking worse. This week was also when I had to present at a pointless Tuesday morning Zoom meeting, so I was already in a skeptical, “why am I doing this” mood.
The routine is simple enough. Apply once in the morning, sometimes I’d do a second application at night if I remembered. I haven’t seen any new hairs. Of course I haven’t. That would be magic. But I started getting a slight, tingly sensation about 15 minutes after applying. Not unpleasant, just… there. Makes you feel like something is happening, even if it’s just the serum doing its job or my skin throwing a tiny protest. I was pretty convinced this was just going to be an expensive way to have a dry scalp.
Week 2-3: Starting to Notice
Okay here’s where it gets interesting. The flakiness calmed down a lot. I think my scalp just got used to it. Around the start of week three, I was in the bathroom under the harsh overhead light and I saw these tiny, light-colored hairs along my hairline. They were super short, like peach fuzz, but they were definitely new. They weren’t thick terminal hairs, more like the vellus hair you see on your face. I wasn’t sure if it was wishful thinking or actual progress, so I didn’t say anything. I just took a picture with my phone’s flash on to compare later.
My hair in general did feel a bit thicker and softer, which I think was the biotin and niacinamide doing their moisturizing thing. There was a noticeable shine, but not a greasy one. It just looked healthier. Also, I applied a little to a patchy spot on my cheek where my beard refuses to connect. My cat decided that week was the perfect time to start waking me up at 5 AM by batting my blinds, so I was applying this stuff in a semi-conscious blur most mornings. I didn’t expect much for my beard that fast.
Month 1: The Real Results
Fast forward to the one-month mark. Time for an honest assessment. The baby hairs along my hairline are still there and they’ve definitely darkened and grown a bit longer. They’re not a full, dense hairline yet, but there’s a faint shadow where there wasn’t one before. It’s subtle, but if you know your own head, you can see the difference. My wife even mentioned my hair “looked fuller” last week without me prompting her, which felt like a huge win.
As for the beard experiment, that patch is still a patch, but it’s less of a barren desert and more like a sparse meadow. There are a dozen or so new, dark hairs sprouting in the bald spot. They’re short, but they’re real. That was a genuine surprise. The biggest non-growth result is the quality of my existing hair. It feels stronger, less prone to breaking when I brush it, and has a healthy sheen. No more flakiness. The application is just a boring part of my routine now, like brushing my teeth.
What didn’t change? It hasn’t magically restored my teenage hairline. The progress is gradual and specific to the areas I target. You have to be consistent. Miss a couple days and you feel like you’re backtracking.
Would I Repurchase?
Yes. For the visible, albeit slow, progress on my hairline and the surprising new beard hairs, it’s worth it. The texture and health of my hair improved a lot, which I didn’t even realize was a goal. It’s not an overnight miracle, but after a month of real use, I can say it works. I’ll be getting another bottle to see what happens in month two.
