Magically, this shampoo smooths the hair but yet not weighing the hair down. The hair strands literally feels hydrated and soft

Overall it is a fine product, but will suit dry hair. The hydration of the shampoo on an oily hair gives the hair a strange feel. It cleans hair and scalp well, but less so with oily hair. This brand has a working cleaning formula in all of their products, so maybe it is something with the Hyaluranic acid, or other ingredient that cause kind of stickiness, but without damage the volume of the hair. Biotin tends to dry hair, and it is not the case with this shampoo, so that is a possitive. It is very foamy and has a scent of a Watermelon flavoured candy.

I love this new line! It makes your hair soft, moisturized, and shiny. I use this with the conditioner and the corresponding oil. My hair is always so smooth.
My hair feels softer more shine to it I don’t think it helps with volume but I have had less hair fall
I needed something to help my menopausal hair desperately. It was falling out in clumps. I truly believe between using this brand as well as taking biotin supplements has saved my hair. Great consistency, smooth feel, lathers and rinses out easily. Has really helped my color treated hair.
This shampoo is what my late 40s hair has been looking for. It is incredible, my hair is smooth and shiny.
this shampoo is very moisturising, smells great, highly recommend to everyone
Giovanni is an automatic win for their Leaping Bunny certification. The new vegan collagen shampoo comes in wasteful plastic - all plastic is replaceable with something automatically reusable like a planter or something that could degrade naturally over time - but is otherwise economical and effective. A small amount makes a huge foamy situation that doesn't strip or sting and is just what a person in between cuts w damaged hair could want except the scent, this line ought to have been fragrance free! but as it is the scent is cheap but doesn't linger (so far as I can tell...I didn't detect it in the bathroom later in the day, a good sign).
