Number 4 Hydrating Set

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).

Worth every (s)cent!
Purchased

And yes, it smells devine! It is a grown-up scent, not for those that want fruity or dessert scented hair. This has a scent that is difficult to describe, but is unmistakable. It will be feminine if you are feminine, or masculine if you are masculine. It is herbal plus clean. It works magic on my hair! It must, because I have never spent more that $20 on shampoo and conditioner combo. I cannot wait to get my full size bottles from the post!

overall, great

The shampoo smells great. My husband doesn't love the smell of the conditioner. Overall, both seem to keep hair pretty hydrated.

Best shampoo/conditioner I've used in a long time
Purchased

This is seriously the best shampoo and conditioner set I've used in a long time. I have pretty dry hair that's thick and wavy and this set keeps it soft and tame. It also leaves my hair very shiny

Amazing!

I got the shampoo and conditioner as a sample and o fell in love instantly! This set does amazing work to dry and damaged hair. I had very dry and brittle hair and just using the sample for three days helped tremendously! This is a great product! I would recommend this to anyone. The price is a little high but the fact that it actually works amazingly I'd say it's so worth it! It is a high concentrated shampoo so you don't need a lot. That's makes it a little better since your paying a high price for such a little amount. This is a set I will always be buying from birchbox.

I am over 50 and color my hair. My biggest problem has been with wiry frizzes. This conditioner is like a lion tamer to my hair. Love this product and would recommend it .

Some of the best product I have used. I love the smell! I can't get enough of the Number4 products. All of them are great! I feel as if I have finally found a product that truly hydrates my hair, and does what it says it will do.

This shampoo/conditioner set is perfect for my fine, straight blonde hair! My hair tends to be dry and this formula is awesome at restoring moisture and restoring shine to my locks!
