Birchbox Breakdown

It’s time to make it rain—on your hair, that is. With its ability to provide all-day moisture, this intensely hydrating shampoo and conditioner is basically a CamelBak for your strands. The satiny shampoo is gentle enough to use every day, while the decadent conditioner helps to bring dry, brittle hair back to life. Both products are loaded with natural moisturizers that calm frizz and restore fried ends while guarding against future damage (flat iron, we’re looking at you).

How to Use

The concentrated shampoo goes a long way. Depending on hair length and thickness, dispense one to two pumps of shampoo into hands and work into lather. Massage into wet strands and rinse thoroughly. Follow with one to two pumps of conditioner, working it through the mid-lengths and ends of hair. Rinse completely and style as usual.

Best hydrating shampoo and conditioner!!!
Purchased

I have tried countless moisturizing shampoo and conditioner sets over the years and this is hands down the winner. My hair has never felt so soft and has never been so free of tangles. It only takes a small amount so I'm sure the bottle will last months.

Excellent Hydration
Purchased

The shampoo and conditioner both smell wonderful - natural, not super chemical-like or heavily fragranced. The shampoo really does hydrate without your hair feeling like it has build up or is weighed down. After using the set a few times consistently, I noticed that my hair felt stronger and stayed happier after blow drying and straightening it. The main issue I had is that it is pricier and I need to use a lot of it at a time (I have long, thick hair), however, I do love my hair and believe this product to be worth the money.

Great Shampoo!

I only bought the Shampoo, but will be purchasing the conditioner soon.

I never thought that fancy shampoos made a difference, but I was wrong!

I have so much less work to do after I shower when I use this Shampoo & Orbrie Gold Lust conditioner.

I would highly recommend to anyone!

Great for fine dry hair

I really don't like shampoos that have a strong scent. THis is the first one that I actually love! It smells so fantastic and its great on my hair. Very gentle and doesn't dry out or leave a residue. Which is awesome because some moisturizing shampoos leave a build up rather quickly.
