Great Value
Purchased

After receiving the shampoo in a box, I decided to purchase this set because it seemed like such a great value. I have been using all the items for about two months now and I'm so impressed. My favorite product of the set is the spray. It smells fantastic too! Once I run out, I will definitely repurchase!

Didn't care for it
Purchased

I'm in the clear minority on this, but I didn't care for these products. The shampoo didn't even work as well as the stuff I can buy at the grocery store for a fraction of the cost; even a tiny bit of the serum left my hair greasy and weighted down; the conditioning mask was okay, but again, I have others that are better; and my feelings on the leave-in treatment are mixed. The smell is horrendous. It stinks to high heaven. I can't even believe some people are saying they want it as perfume! I gag every time I use it. It's a fantastic detangler, however, one of the best I've ever used. But again, it didn't condition well, and left my hair looking gross. Other detanglers/leave-in conditioners work so much better on my hair, and don't make me want to vomit from the smell. Overall, I wouldn't recommend these products to anyone, especially for such a steep price.

eh
Purchased

I got some of these samples in a box and really liked it so I ordered the full sized kit but I am not crazy about it. My hair is really fine so when I used it everyday, it really weighed my hair down and made it greasy. I also had some technical issues with the pump on the conditioner which was a little frustrating.

soft and hydrating

made my hair a little more hydrated but i dont think its worth it to pay that much. my hair was still a bit frizzy after. also the sample size was only enough for my end strands as i have long, thick hair.

Like it.

I LOVE LOVE LOVE the Prep and Protect and the conditioner. But the shampoo is weird and a little sticky. I will definitely order Prep and Protect again!

Great combo pack for gift
Purchased

Excellent packaging and perfect sizes for travel or a nice luxurious gift. The only product in the kit that I wasn't crazy about was the spray (not that it didn't deliver, it is a great product but smells a bit like licorice which I don't like).

Mixed Results
Purchased

First off this line of hair products smell really wonderful. I am a fan of the spray, however after using the shampoo for a couple weeks I started to get a decent amount of build-up and it was difficult to get it to lather properly, and then it wouldn't wash out of my hair, causing it to get greasier, much faster than normal.
I use the deep conditioner one or two times a week and am pretty pleased with the results, but I probably wouldn't reorder this set because of the issues I had with the shampoo and I have found better leave in conditioners than this one.

Good amount of stuff for the price
Purchased

I got the clarifying shampoo sample in a birchbox and wanted some more so I purchased the whole kit so I could try out their other products. Everything smells really good. I use the hair detangler after I shower and I use the shampoo and conditioner a couple times a week. I haven't tried the oil yet. I think you get a lot for the price but I probably won't purchase anything individually again. I just don't really notice a difference in my hair other than the yummy smell!

Might be right for you, might not
Purchased

This is a fantastic value given that you get a full size shampoo and full size Prep & Protect spray in the kit. However, this product was just too much for me. The shampoo is great for once a week or so but for every day use it is just too rich. And the spray might be great for heat protection and conditioning but it didn't have any impact on styling. Big investment even with this being a value for it to not be a daily use item.
