Easy to use, no rinse serum
[This review was collected as part of a promotion.] I have never used a hair serum before and having trialed this for the last few weeks I can now really see the benefits of using a hair serum. The fact that it was leave in and no rinse made using it so much easier as I didn’t have to worry about it the following day. I did however, on a few occasions, find my scalp to be a little oily than usual. This may have been down to me using too much of the serum however, because as time went on this issue seemed to resolve itself. A little went a long way and I feel now that I am starting to see the benefits from it. My hair doesn’t appear to be as aged and looks fresh straight away the day after using, with my frizz lessened and my hair shinier too. I think the product will last a significant amount of time so is also worth the investment, as little and twice weekly has worked great for me!

Overnight serum is amazing
[This review was collected as part of a promotion.] I like this serum after a good wash and condition. This serum has hydrating benefits. It leaves my hair feeling soft in the morning and reduces the frizz. My hair does not feel so dull and dry after using this. Feels super light weight on the hair and doesn’t weigh my strands down. Smells like luxurious and reminds me of a pampering day in the salon. Bottle says to use 1 pump but this really depends on your hair type as I’ve had to use 5 to ensure product evenly distributed over my whole head of hair. Will definitely continue using this serum alongside other products in this range. It’s going to make wash days even easier for me and I love that

Makes hair shine
[This review was collected as part of a promotion.] The Keratase over night serum is beautiful! Smells so good and after a week of using it on hair, every night, my hair is so soft and shiny. It’s a huge bottle as well, so will last a while.

Not for me
[This review was collected as part of a promotion.] Similar to my review on the shampoo and mask I’m not I’m not in love with this product like I thought I would be. It doesn’t leave my hair how I imagined and the serum especially with in a day my hair was like a grease ball and feeling so heavy . I usually love the brand and invest in the bundles as the product you only need to use such a tiny amount so although expensive they do last and usually offer fantastic results but my hair just didn’t love this bundle this time round

Effect after first use
[This review was collected as part of a promotion.] A very easy-to-use night serum with a pump. It smells luxurious. It absorbs quickly, and in the morning, hair is shiny, nourished, soft, and frizz-free. I recommend it.

The best serum I’ve ever tried
[This review was collected as part of a promotion.] I don’t know how Kerastase do it, but they do it.
I’m no stranger to Kerastase, I’ve used their products for years, but this range is honestly something else.
I struggle with frizz, dullness, tangles, AND lack of volume, so my hair is quite difficult.
This serum honestly does it all for me. I use it overnight, and my hair becomes instantly more shiny, easier to style, easy to derangle, beautifully silky and so, so healthy looking. It feels nourished. Best thing is that I don’t have to choose between having nice soft hair and volume - the serum does not weigh my hair down at all, which is super important to me. The scent is absolutely heavenly and as an added bonus the beautiful bottle looks so good on my dressing table.
A tiny bit goes a REALLY long way, one pump is more than enough, and it’s honestly something else very lightweight and yet it works so well. It absorbs instantly. It’s magic, it makes my hair so ALIVE, it’s worth every penny and I am beyond happy with it!

Absolutely amazing
[This review was collected as part of a promotion.] I don’t know what I love more in this range. It’s just a perfect combination of all 3. Serum is lovely, makes hair look extremely good even without any styling, smells great and it’s easy to rinse off of your hands

Luxury
[This review was collected as part of a promotion.] This serum is everything! The smell is gorgeous and I have that salon feel after using it. My hair feels super silky smooth once dried. Using it alongside the shampoo and masque has made a huge difference to my hair. It is less damaged and so much more healthy! Highly recommend
