Smells great and works well for dry hair.
Purchased

I bought this as a birthday gift for my mom (which she loved!) and have seriously been tempted to steal it for myself. The smell is heavenly and lasts long and the product texture is velvety and thick and really works to make dry hair feel soft. My usually dry ends have never been better and my mom feels the same way. Great gift and a great buy.

Love the conditioner
Purchased

This set did wonders for my damaged hair - Especially the conditioner, which instantly made my hair feel soft and healthy. The shampoo doesn't lather much, which is hard to get used to, and it was hard to tell if the protectant spray really made an impact on my thick hair, but overall I was pleased with the end result.

One use, but very happy so far
Purchased

I have only used this product once so far, but it has had great results. My hair felt somewhat brittle when it was drying, but it didn't look greasy for 3 days of non wash. All of the products smell wonderful and I especially love the detangler. I plan on incorporating this in my weekly beauty routine.

Great Value
Purchased

I love the longevity of the product and most importantly, the results. I have very fine but dry hair so it has been difficult to find a happy medium. The shampoo and the spray are full size products and the oil is concentrated so the sample size will last you several weeks.

Great value
Purchased

I'm really happy with this. I have shoulder length hair that is fine in texture, but abundant. The entire line smells absolutely amazing, but light enough to not irritate. Initially, I was going to just buy the full size clarifying shampoo, but this wasn't a whole lot more with my points and includes a full sized leave in conditioner, so I figured why not try the other stuff! The clarifying shampoo is fantastic as it removes buildup and moisturizes (it has oils in it that somehow don't weigh hair down). When I first shampooed with this, I felt the oils in it and worried that my hair would be a greasy, gross mess, but it left me with soft, clean hair. I really can't see using it more than once a week, though- it's crazy that they suggest that you can use it daily! The mask leaves my hair feeling soft, smooth and not at all weighed down. Still, a mask from Earth Science that I use works a lot better, at a fraction of the cost, so I probably won't purchase a full size of this. Both the mask and the shampoo are super concentrated, so a little goes a very long way. The leave in conditioner is really nice and light, it detangles my hair and leaves it smelling heavenly! I don't know that it's worth the retail price of $32, though. I have not tried the repair oil. If you have the extra money, this kit is well worth trying out.

Great value!
Purchased

I wanted to buy the Prep and Protect, but opted for the kit due to the great value. All products smell heavenly and work super well.
I'm not a huge fan of daily use of the clarifying shampoo, but I think it works wonders when I use it once every two weeks.

I love this stuff! Well- the masque mostly!
Purchased

I fell in love with the shampoo scent after my monthly sample. The shampoo left my hair clean and shiny, so I thought I'd try the other products. It's a bit pricey, but I LOVE the hair mask! I have very thick and long hair that is almost impossible to get the tangles out of. The mask did the job and left my hair feeling super luxurious! It's expensive, but I'm going to buy it again. As for the scent, it was a bit overwhelming this time around. It is a lovely scent, but PLEASE reformulate and use a bit less. The Super Comb spray, which does a great job of de-frizzing my hair, is sitting on a shelf unused because it has so much fragrance that it irritates my allergies!! Less is more, Number 4, less is more.

LOVE THIS

LOVE THIS STUFF! The scent is heavenly! The shampoo doesn't lather up too well at all, but the overall effect is great. The heat protectant is my fave.

AMAZING SMELL
Purchased

Love the Super Comb and protect spray. Will definitely be reordering that. The shampoo didn't work well on my hair but doubles as a body wash, so I definitely got my use out of it. The products have a clean fresh scent which i find amazing.
