Review on 💙 Oligo Professionnel Blacklight Blue Shampoo & Conditioner 8.5oz Duo Bundle: Ultimate hair care for mesmerizing shine and vibrant color! by Amy Fowler

This product suits me. I go from medium brown to gray and after a year the older hair is horribly coppery and orange. I've definitely seen a difference since using the blue shampoo and conditioner. It doesn't dry out my hair, doesn't turn my hands blue or rub off as I've seen in some reviews. It simply softens copper tips to a darker color and lightens new gray sprouts. This softens the dividing line a bit. I guess I took a chance now as I see some reviews saying it's fake! But it seems legit and it works for me. Much luck!
