The first couple of weeks, my eyebrows looked perfect. From the second week, on, I noticed the hairs weren't "stuck" in place like they were initially, but after brushing them up with a spoolie, they stayed put much easier through the day. The fluffed-up shape didn't last for 6-8 weeks, but keep in mind I have quite unruly brows, and someone with thinner brow hairs may experience different results.
This is the second time I've tried at-home brow lamination and have been happy with the results both times. However, I have to admit I'd be curious to see if having it done in a salon by a professional would have a different effect, as their products are probably stronger and therefore longer lasting.
And while doing this at home works for me, it's definitely not for everyone (as I said, professionals would not recommend trying this at home). For most people, I would definitely recommend going to one of the salons that offer the treatment professionally. Keep in mind the people that do this in a salon have been doing so for years and are brow specialists that know what suits your face shape and brows.
