Birchbox Breakdown

Just like the sands of your favorite beaches, hair can erode over time. And just like you might erect barriers to the sea, your hair needs strategic reinforcements. This restoring shampoo heals strands from within to strengthen limp hairwhile imparting a smooth shine on the surface.

How to Use

Apply a quarter-sized dollop to wet hair and scalp. Massage until lathered, then rinse thoroughly.

Really good..

You can tell the difference when you use this shampoo, it feels luxurious. The smell and lather are great. When you work it through your scalp it feels luxurious and strong. When I first started using, my hair was behaving well but it stopped. This whole green line is not a miracle worker but the quality is nice. I don't know if I would repurchase again because it's not a product I can't live without.

I have used Kerastase shampoo for many years, at the advice of my hair stylist. So nice to get it from Birchbox and earn points towards future purchases.

Love love this shampoo!
Purchased

I have very fine, natural blond hair. This shampoo made my hair super shiny, smelled amazing, and did not add weight. Despite the price--I am a Kerastase lover!

Best Shampoo for Damaged Hair

I have long, bleach blonde hair and I've been using this shampoo for years. It is a lifesaver for helping with split ends and breakage.

Gentle and adds volume
Purchased

This shampoo smells amazing and works wonders on my fine hair. It adds shine,strength, and volume. It is creamy but does not weigh hair down at all. I think this would work for all hair types in need of damage repair.

Repairs my hair

I have been using Kerastase for awhile now, it really improves my dry, brittle hair. It doesn't just coat it, it repairs my hair and I have less noticeable damage.

Noticed a difference!
Purchased

I am very picky on shampoos and conditioners. I normally can't tell a real difference with shampoo or I hate it because it's too drying or opposite too heavy on my hair and makes it look weighed down and just a weird texture that is hard to style. I have used this shampoo with 3 different conditioners that I like and have achieved great results with all 3. This shampoo is noticeably different than others I like. It makes my hair feel so soft and healthy and great texture and easy to style. Loooove it! So glad I used my birchbox points on this! Worth the high price.
