- jenaReviewingRosemary Hair Duo | Multi-ProteinI recommend this productWhat are your skin concerns? AgingWhat are your hair concerns? ThinningRated 5 out of 5 stars5/6/26Amazing, not a gimmick!
I lost a lot of hair after I had a baby. I was desperate for something to help grow my hair back, make it fuller and not look all around so terrible. At first, I got worried. I thought I was losing a lot of hair in the shower using this, but whatever happened…..worked! My hair is growing back so much I can see all two inch regrowth all over my scalp. This is not a paid review. This is an honest review.
