I’m obsessed with this serum for so many reasons! I have super color treated, damaged, hair and a lot of it - just for reference. One : it lasts me forever because I only need a drop, and I have a ton of hair. It’s a great value! Two : the smell is incredible. The whole line is intoxicating and I can’t get enough of it. And three, of course the most important, is how it makes my hair feel! It’s silky and soft and really helps to bring the shine back and make it look healthy again. Would totally recommend!
