      Smells fantastic and doesn’t make your hair greasy and you do see growth

      What impresses me most is that I’m not seeing much hair shedding anymore, especially in my brush. I love the smell and it doesn’t make your hair greasy. I am very consistent and faithful with my dosage every night before I go to bed. I will continue to use the product Until I reach the bottom of the bottle.

      So Easy

      It’s almost a month into using this product. It’s so easy to use, and leaves no residue. I’m committed to continue using it. Can’t wait to see changes.

      Used daily now for three weeks - hair feels thicker! Also seem to see a lot less hair on my brush. Looking forward to even better results in the future!

      I have used their other serum and it worked very well. I am trying this advanced version to see the difference it will make. So far s

      o good, I like the larger version as you dont have to worry about it every month.
