Moderate or gradual hair thinningDo you experience any scalp concerns? SensitivityRated 5 out of 5 stars3 days agoLove it
I have been using this serum for just over a month and absolutely love it. I started using it when I began having more shedding than usual. It is definitely helping with the shedding, it does not irritate my sensitive scalp as other scalp serums do, and it does not weigh down my fine hair at all. This will be a new staple in my daily hair routine and I will continue to purchase!

I have a very itchy scalp, I have tried every shampoo on the market. This serum is a game changer because it remains on my scalp after I wash. Amazing product.
