Groh® Scalp Hair Rejuvenating Serum
Groh scalp hair rejuv serum
Really great. I have a low thyroid and one of the characteristics is an itchy, flaky scalp. This product has been incredibly helpful. I also bought it to rejuv my breakage. To be honest I haven't really noticed a difference in the breakage, but that's bc I probably haven't given it a fair chance, i.e., I only use the product about every 3 nights. I've thought about trying the supplement, but my budget doesn't allow, so for now just sticking with the serum.
