I tried it for a bit. Once you stop a massive shedding occurs. It’s damaged my hairline. If you’re good with using it religiously and never stopping, it works wonders. However, it’s a commitment for life (one I’m not willing to make with a research chemical that never made it to market). If you have to stop for any reason, a massive shed occurs and does not come back. You should check our Derek on More Plates More Dates on YouTube. He stopped for a few weeks and it crucified his hairline. Once he went back on, it repaired.
