"I love the way this stuff makes my hair feel, it feels clean without feeling stripped and the conditioner really makes my hair soft. My waves are also thriving on it. I’d give 5 stars but the only down side is the scent doesn’t really stay as long as I’d like. When I use the leave in conditioner I have I smell that until the next wash day but the shampoo and conditioner don’t last that long :("
"Too good and so subtle on your skin"
"I purchased this line 1 year ago but ended up replacing it with something else at the time so I forgot about these under my sink until a few days ago when I was deep cleaning my bathroom LOL. I’m actually very impressed by both the shampoo and conditioner so far after only 2 washes. I wash my hair daily since I’m naturally very oily. The shampoo lathers very nicely (I use 4-6 pumps for a great lather) and it cleanses my scalp thoroughly while leaving my hair length so soft/silky even after rinsing it out which I love and I’m surprised by because many shampoos leave my hair overly stripped and dry. The conditioner is more of a lightweight consistency but it’s so creamy and nourishing only if I use 10-12 pumps of it (yes that seems excessive but if you have long hair like me we absolutely need all of the nourishment we can get to keep our hair healthy, 2-4 pumps is not enough at all). I rinse the conditioner out after 3-5 minutes and I air dry my hair. My hair not only feels properly clean but so soft and flowy too. Not weighed down at all. The scent of these is light and citrusy, not overpowering at all. It gives off spring and summer vibes which I love personally. Even though the products look small, they’ll last me another 1-2 months even with daily use so I think it’s worth every penny. I’m honestly very impressed with this line and you should buy it. It’s worth the hype and money!"

"Smells very nice. Made my hair feel soft and healthy almost immediately and my scalp feels nice and clean!"
"I like that I can feel the quality of the shampoo. By that, I mean that it does not feel as if it's all soap and nothing else. I'm not sure as yet how much smoothness the shampoo contributes to my hair. Time will tell."
"Shampoo is clean and light for hair but observing more hair fall."
"smooths out the wild flyaways and waves as promised. love the scent."
