Good product although I feel that there are better serums on the market 

It’s oily yet drying. Hair looks shiny, but feels dry and tangles a lot! If you’re thinking of improving your hair condition, I’d recommend having a look at something else

Serum is not smelling good like rest of the products from this line. Although hair is looking great with it, I have a feeling it dryes it coz of many alcohol in ingredients.

I never thought my hair could recover from the amount of bleach and sun I had let happen. With this product, my hair has never been in condition. My hair is soft and there is no dryness. 10/10 would recommend Will buy again and again for the rest of my life

I have really long hair that reaches the centre of my back, and it often dry and difficult to get products that don't dry it out further/aren't too heavy for my hair. I've tried almost everything from drugstore to high-end, and this one has been on of the best investments I've made! It's travel friendly, beautiful packaging, one pump literally is the perfect amount for my hair (most products take 3-5pumps or more if needed) and it has never looked better - it's silky smooth, split ends are barely there compared to before, not heavy or dryed out, it's now actually in normal condition and flows beautifully compared to what it used to be, and for the price, it's a little bit high but for how long it lasts, worth every bit. This has become a holy grail for me, I just hope L'Oreal doesn't change anything like it has with some previous products!
