The Serum actually seems to grow hair. I use it daily on needed areas and they, over time,filled in a bit which is very good.

Love this.

Helps my hair grow longer. But sadly no new hair growth. Helps with length but not with thickness.

Love Groh Serum

Hi, first off I love the product. I was buying on Amazon and it was sold out for a long while. So I bought direct. But, the bottles I received direct seem diluted. The color is half the darkness and does not seem as thick either. So the bottles I got direct I mixed with two bottles from Amazon. Can you explain why the big difference? Also, the bottles direct did not come with an applicator.
