PROCERIN SHAMPOO ($20 @ Amazon.com)
Hair loss shampoos can sometimes be hit or miss, but Procerin has an excellent reputation. Like Provillus, it reduces hair-loss by blocking DHT, except Procerin is used in a similar way to regular shampoo (Provillus is a spray, not a shampoo).
It’s free of Sodium dodecyl sulfate (SLS) and parabens — which can irritate skin after prolonged use. If you’re an overachiever who likes to go the extra mile, Procerin also sells a supplement specifically meant to be taken alongside use of the shampoo as a 2-step program.
