I went with a shampoo and conditioner set (8oz each). For my hair type, I selected straight + fine + normal. My goals were shine, volumize, anti-frizz, strengthen, and replenish hair. I picked Nude (P)each for the fragrance, and made my shampoo blue and my conditioner pink. Each bottle comes with a pump for ease of use, and they put your name right on the side of the bottle!
What I Liked:

I have been using nothing but these products for the last 3 months to really see if they have made a difference, and I do think the products mostly delivered on my hair goals. They didn't weigh my hair down or leave it greasy. My hair definitely has more volume than it used to, and I can tell it has gotten healthier. It's way softer than it used to be! There is also a little bit of added shine, although not a ton.
I received my set back around January 10th, and STILL have some product left! I am close to being out of shampoo, but have about a quarter of the conditioner remaining. How is it everyone always runs out of shampoo first?! I wash my hair probably 4-5 times a week, and my hair is almost down to my butt, so that's definitely saying something about how a little product really does go a long way. And I'm glad, because this was a bit of a splurge at $41 for the set.
What I Didn't Like:

The scent of my products was pleasant, but I wouldn't have called it peach, so that was a little bit misleading. I don't think the anti-frizz element did much, although that could just be that my hair is damaged and needs a trim vs anything the products could fix.
