Query: Love it!

My hair and also my husbands hair has been thinning terribly as of late. Mine more so as I do a ketogenic diet. I had read about biotin shampoo and my doctor also recommended it. This made my hair feel quite nice, I have had less loss over the last week than previous weeks. I am following the whole regiment and so far love it, this spray adds a little extra for volume and also gives my hair a nice finished look when drying and using straightening tool.
