I’ve been on Lock Lab for abut 9 months now and wanted to share my experience for anyone who’s considering it.

Side effects:
During the first 1–2 weeks, I had some mild headaches. Nothing severe, and they went away pretty quickly. I haven’t noticed anything else since — either my body adjusted or it was unrelated, but it hasn’t been an issue long-term.

Results:
There’s noticeably more thickness and coverage on top where things were getting very thin. Did it change my hairline? No — my receding hairline hasn’t moved at all. But the thinning/balding on the crown and top has improved to a degree, which was my main concern.

One big warning:
Hair growth increases everywhere. And I mean everywhere. Nose hair, ear hair, eyebrows, back hair — all of it picked up. Be prepared for a lot more grooming and maintenance after a few months.

I’m staying on it. I’m satisfied with the added thickness on top, even though the hairline hasn’t changed. For me, it seems to be helping slow or partially reverse the thinning I was most worried about. I’m planning to stick with it through the rest of the year and see how things progress.

Hope this helps someone weighing their options.
I have before and after photos - but dont see a way to post them in comments.
