Great Product Line for Dry, Overworked Hair
Purchased

I recently went from brunette to blonde and took a trip to Costa Rica where I spent alot of time in the water and sun. This product revived my hair. The scent is pleasant and the products preserve color as they are sulfate free. The shampoo doesn't strip your hair of its natural oils and the leave in conditioner makes tangled, dry hair more manageable while protecting. Great products. My new love.

Love the whole kit!
Purchased

I am officially obsessed with Number 4. I was torn because, given the priciness, I was considering hedging my bets and buying the volumizing shampoo (I have fine hair, and not enough of it). In the end, I decided to get this b/c I already knew I liked the clarifying shampoo and I *love* the leave in treatment. Other reviewers note a smell - I don't really notice much of one at all. The serum and masque are terrific as well. All in all, would highly recommend buying.

Must Buy!!
Purchased

I have a ton of fine hair on my head and living in the South does not help my hair at all! It can be hard to manage and the humidity can make it go crazy! This kit has already made my hair so much more manageable and I have only had it a week! It comes with two generous samples of the oil and masque, and the two full size products alone can't be purchased for the same price!! This is such a great buy to me!!! It leaves my hair smelling so amazing that even a shift as a chef in a hot kitchen full of food can't take the smell fully away!! So addicted to this kit already!!

The best clarifying shampoo out there!
Purchased

I love No.4 hair products! They work well with my hair type (color-processed) and the smell is wonderful! I use the clarifying shampoo and masque at least 3 times per week to keep my long locks looking healthy and smooth! The kit is a great purchase price for the amount of product you receive.

Number 4 comb and protect leave in spray!

I was a hairdresser for 25 yrs. This is absolutely the best leave in spray I have ever used in my life. My hair is coarse and curly, one spritz and you will see a difference. It doesn't weigh you hair down and the feel of your hair after using it is soft and controllable. I received it in my box this month! Thank you Birchbox!

Worth every penny!
Purchased

I received the trial size cleanser in my birchbox and loved it so much, I had to order the full size. I also love the conditioner and leave in spray. I use this once a week, and my hair and scalp always feel so clean and fresh after. I've never found a clarifying shampoo that truly feels like it cuts through all the buildup and leaves your hair so refreshed!

Great value!
Purchased

These products are top notch. The leave in Prep& Protect is an all-time fave. My hair feels great and has volume. The shampoo is just as impressive...a very little bit goes a long way. The best part about this kit is the savings! Not only is it a discounted price, but it qualifies for free shipping as well--bonus!

IN LOVE
Purchased

I received a sample of this shampoo and conditioner and FELL IN LOVE, so much so that I ordered this kit right away! I am very hard on my hair I die, change it, burn it, style it, and everything else! So needless to say I need my hair products to step up to the plate! The shampoo removes all the build up and removes all the kinks so i dont condition every time. I will never live with out the Prep and Protect spray again! It makes it very silky and smooth! Its perfect for detangling your hair when dirt too!

Great value!
Purchased

I received the shampoo in my first Birchbox and loved it so I knew I wanted that but after seeing all the positive reviews about this set I was curious. I love it! My favorite thing besides the shampoo is the detangling/protecting spray. I don't even have to use conditioner and I just spray it on after the shower and comb through my hair. The conditioner is also nice but for me I can't use that and the detangling spray (the box says you can but I don't think that's a good idea for thin/fine hair). I haven't tried the hair oil yet. These products give my hair great volume and I like the smell.
