Use Number 4TM Hair Care’s Clarifying Shampoo mild shampoo every day without worrying about drying out strands. 

Birchbox Breakdown

Let’s face it: We subject our tresses to a lot of stress. From teasing to highlighting, it’s a wonder they haven’t broken up with us yet. To help repair our relationship (and our split ends), we swear by this kit from Number 4™ Hair Care. It’s got everything you need to get rid of product buildup and bring back smoothness and shine. A $76 value!

How it Works

The Clarifying Shampoo uses botanical ingredients to wash away all the things you don’t want in your hair (like chlorine and mineral deposits), while leaving the things you do (like your new highlights). Soy proteins in the conditioning spray and masque help rebuild weakened hair from the inside out. Bonus: The travel-sized Fluoro5 Elixer™ Restore & Repair Oil protects against UV rays and reduces drying time.

How to Use

All products in this kit are gentle enough to use every day, or you can use them once a week as a special spa treat. After lathering up with the Clarifying Shampoo (that can double as a body wash, btw!), coat hair with the Reconstructing Masque and leave on for five minutes and rinse. Towel-dry, then spritz the Super Comb™ Prep & Protect throughout strands. Apply a small amount of the Fluoro5 Elixer™ Restore & Repair Oil to damp hair and style as usual.

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.

LOVE Number 4

This stuff is a MIRACLE for my hair! I use about once a week to give my hair the pick-me-up it needs. It also smells amazing! I can't say enough great things about these products - the only downfall is the price. Totally worth it though if you can afford it!

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.

My hair has never been so soft
Purchased

This kit is amazing! The shampoo is concentrated, so this bottle just keeps going and going and going... The conditioner is truly a deep conditioning treatment, but it also rinses completely clean, so there's no gunky residue to start your styling with. The Prep and Protect spray is perfect for my very fine, tangle-prone hair. No greasiness or added weight, just protection from my blow drier and round brush! I'll be honest, I didn't try the oil, because, as I mentioned, I have very fine hair and I'm a little afraid of any oil treatments/products.

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!

Good stuff
Purchased

I first sample this shampoo in my birchbox and liked it so much I was willing to try the whole set. I was not disappointed at all. The shampoo is hands down my favorite and the hair masque does wonders on my hair. The spray leaves my hair soft and shiny on days I skip conditioning. I feel like it was well worth the money.

This set of products was amazing! I LOVE the shampoo- I feel like it strips away all the dirt and oil and gets my hair truly CLEAN in a way that no other shampoo does! After I shampoo with this product- my hair is clean, light and bouncy for days! The conditioning spray is like the cherry on top- it protects my hair from styling heat and allows my hair to grow long and strong. Lastly, the repair mask keeps my ends looking brand new. A great bundle that has lasted me months!

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).
