 Trustindex verifies that the original source of the review is Google. I have been using GR-7 for three months. Overall experience is good. The first month took a little bit effort as I couldn’t wash my hair for the first seven days as instructed. After one month, I only need to apply twice a week to maintain the colors.

 Trustindex verifies that the original source of the review is Google. I've been using the GR-7 hair loss product and here are my thoughts. My hair feels significantly smoother and more manageable since I started using this product.While it's still early days, I've noticed a reduction in the amount of hair I lose daily. It seems like more time is needed to see the full benefits. I'm optimistic but still waiting for more noticeable improvement in hair regrowth. Overall, I'm quite satisfied with the initial results. The smoother hair is a definite plus, and the reduction in hair loss is promising. I'm looking forward to seeing more substantial improvements with continued use.

 Trustindex verifies that the original source of the review is Google. This actually works! I wish I took before photos but I honestly didn’t think it would work so well. I noticed a clear improvement in my grey hair after the 3rd day. By the 2 week mark I couldn’t see any of my grey hair anymore.
