AMAZING Product…HORRIBLE packaging care!
I absolutely love this shampoo! It’s the best and it’s not cheap! Very saddened that this pricy shampoo has such an unthoughtful package care! I lost about a week of product due to horrible packaging! I know you are better, Sephora!

I have used this as directed for half the bottle and I truly see no difference. Not worth the price for me since I have thick and long hair, never been colored.

Works well with the conditioner
It works well but I do not like the smell. On the border of grapefruit with a tinge of body odor but does keep my smooth.

Not the best
Very mid product. I prefer the k18 peptide shampoo by a long shot. Seems like they changed the formula for damage shield. Side note: it does contain sodium chloride so don’t use on a keratin!

Used to be good, new formula and it’s awful
I used the shampoo and conditioner last summer and it did wonders for my hair. Just repurchased back in March and my hair feels horrible. I’ve never had my hair become greasy immediately after washing and blow drying. But this has made my hair become greasy and flaky because it has been so dried out and I don’t even realize until now. My scalp feels like it’s burning after every wash.

Meh
Wanted to love this one. It very hydrating but so heavy on my fine hair. You can literally use a bit of it and it lathers so well. It just feels too heavy and makes my hair oily. Had to return.

My hair is healthier!
I have been using the Damage Shield shampoo from K18 for a few years now and it has been amazing for my hair. My hair is healthier, has less split ends and overall less frizz. This shampoo lathers beautifully. A little bit goes a long way here. The bottle lasts me a while.

Dry Scalp-Hair Falling Out
Wow I wish I had read the reviews before I bought this. My scalp has never been this dry in my life and that is with me only washing it every 4-5 days. I have SO much dandruff with this shampoo and I’ve noticed a lot of my hair falling out.

One thing I really liked is how well it cleans my scalp—especially before going in with a hair mask. It leaves my scalp feeling fresh without that overly stripped, squeaky feeling you get from harsher shampoos, which I appreciated. That said, I did notice that at times my hair felt a bit dry and slightly weaker after using it. Because of that, I found it works best when you’re mindful of how much you use. A little truly goes a long way, and I had better results doing a lighter first wash followed by a slightly more thorough second shampoo. I’d recommend this shampoo for people who struggle with oiliness or have damage and breakage, since it does a good job at cleansing without completely compromising the hair. I used it long enough to see a slight improvement in my hair’s overall condition, which is a plus. However, despite the benefits, I’m not completely sold on repurchasing it. It works well, but for me, it didn’t quite stand out enough to become a staple.
