Birchbox Breakdown

We know we’re stuck in a hair rut when we find ourselves in a ponytail or topknot every day of the week. But fear not: There’s no need to hide tired, weighed-down hair in ponytails forever. We’re relying on these two standout products from Number 4™ to cleanse, hydrate, and revive our sorry strands back to health. Say farewell to that security-blanket hair tie you keep around your wrist—there’s a whole world of ’dos just waiting for you.

How to Use

Squeeze one pump of Clarifying Shampoo into your hand, lather up, and rinse clean with warm water. Next, wring excess water from your hair and apply the Reconstructing Masque, starting at the ends and working your way up to your scalp. Let it do its thing for two to five minutes, then rinse clean and style as usual.

This set is great. The clarifying shampoo gets rid of product buildup, and leaves my hair feeling squeaky clean. And then the masque is nice and thick, so it really moisturizes my strands. It is quite expensive, but if you're looking for a good hair masque set and have the points to spend I would suggest you pick this up!

I love the product, not the price!

I was so excited to try this product. The smell is wonderful! It clarifies without stripping, and the masque made my hair feel so healthy. I really thought this would be a treat and expected it to be a bit pricey, but $88, no matter how concentrated, is a no go for me. I just can't do it!

Scent is awesome
Purchased

I absolutely love this shampoo! It has a musky smell, which I love! My only complaint would be that they bottles are small for the high price and the pump on my shampoo is broken.

Everything's perfect, except the price

I instantly fell in love with my samples of this set that I received. It pulled my hair out of the funky state it has been in lately (dry, frizzy, annoying) and made it feel healthy, strong, and smooth again! I have been saving my BB points for that "perfect" thing to come along that I couldn't live without, and I decided that THIS was it! Until... I pulled it up and looked at the price. OUCH. This stuff works great but $88.00 for such small sizes is ridiculous. Off to the drawing board again for my hair :(

Overpriced. Waste of money.
Purchased

Do not waste your money on this set... Regardless of how "high end" a shampoo company is... This set is completely misleading. $88 in this set gets you (yes nice quality shampoo) but a whole 8.5 oz and a hair masque that is a mere 5 oz. again wonderful product but crazy overpriced for the small set. Never again.
