Nutritive Nourishing Hair Serum with Niacinamide, Overnight Leave-In Treatment for Dry Hair, Lightweight and Non-Greasy, 8H Magic Night Serum

I'm already a big fan of the brand, but I love this. I lighten my hair, so I'm conscious that it always needs moisture. I apply every night and my hair is smooth and silky in the morning. I feel like there is less frizz - especially when combined with a silk pillowcase. My favourite thing is that it doesn't feel heavy or greasy - it just works right into my hair seamlessly. And, as an added bonus, it smells delightful. The price did make me wince, but you get a lot of product for that, and you only use a small amount each time, so let's do the maths! If we assume that each pump is 0.25ml (thanks Copilot), then that's 360 pumps per bottle. It suggests you use 1-2 for short-mid hair or 3-4 for long - depending on texture, so let's go with the average: 3 pumps, that means it will last 120 uses - or roughly 4 months, and the price per day/use is about 33p. So actually, it's really not that bad at all.

I absolutely adore this product and wouldn't be without it. It comes in a stylish, quality glass bottle. I use the product on my waist length, naturally wavy hair. It works well to nourish my hair and tame frizz. I know it's an overnight treatment but I use it as and when I need it. It doesn't feel greasy at all and seems to soak right in creating a smooth and hydrated feel to my hair. I've been using this product for a while and I think it helps prevent breakage and promote hair growth and strength. It smells amazing too which is always a bonus. If you're looking for a hair product that will nourish your long locks, without being greasy and that smells divine then this is the product for you. Yes, it is expensive but you don't need loads and it seems to last a long while. I think it's worth every penny to keep my locks in tip top condition. It took me a fair while to grow my hair long and this product helps to keep it strong and stay long.

OK, so this stuff is brilliant. I have hair that does NOT want to be bleached, however I persist in bleaching it and inevitably suffer from breakage. I recently bought this after going blonde again, and it has been an absolutely gamechanger. My hair is the healthiest it has EVER been post-bleaching. I run a squirt or two of it through my hair at bedtime, concentrating on the front of my hair where I tend to get the most breakage. I also occasionally run it through my hair during the day to smooth it out a bit. My hair tends to look greasy when I apply other moisturising products, but it just drinks this in and doesn't mean I have to rewash/restyle after application. I've been using it for just over a month and I'm about halfway through the tube, so I've just ordered a second one on the Black Friday offer. Yes, it's more expensive than other options, but it is significantly better than anything else I've tried (and I've tried a silly amount of products). Even at full price, paying £25-ish quid per month to stop my hair from being entirely frazzled is worth it to me. I can't recommend enough, I'm just annoyed that. It's so good I'm now commited to using this product for life 😂 PS there is a specific version of this for blonde hair, but my hairdresser warned me that if you prefer warmer tones in your hair, the other one will bring out silver tones instead (similar to purple shampoo). So the other version is probably better for cool blondes, but if you're like me I would stick to this one (or risk having to re-tone your hair more regularly).

Can’t recommend this enough. Have been trying both Kerastase and Olaplex shampoo and conditioners, also Kerastase elixir oil, which are all good but this one is a stand out hit. It makes my hair feel so soft and smooth with only a few drops on medium/long hair, and smells lovely. I have very fine hair and it doesn’t weigh it down or make it greasy - in fact I can go an extra day before washing it after using this. Of all the expensive stuff I’ve tried, this is the one I’ll keep on buying.

I bought this product on sale because, honestly, I think it’s quite expensive at its regular price. It was highly recommended on TikTok, where people were praising it and claiming it made their hair look amazing.To be honest, I haven’t noticed any difference in my hair at all. Unfortunately, I can’t say anything positive about this hair product, as it simply didn’t work for me.

Very nice product. Wonderful scent. Helped with loss. But doesn’t last very long, so works out very expensive.

Really good, not greasy, leaves your hair clean and hydrated the following day

Smells lovely but Doesn’t work for me

O nome dele nao mente é absurdo, parece milagre divino. Meu cabelo tem química, fiz descoloração e tinta, quando passo o serum, no momento da aplicação, ja fica outro cabelo, no outro dia parece mega hidratado e o brilho é de outro mundo. Eu amei ele e vale cada centavo, qualquer cabelo vai ficar incrível com ele e vou economizar pra comprar mais quando acabar. Único ponto negativo e que acaba muito rapido, nao rende muito, mas como eu disse vale muito a pena o cabelo fica de propaganda e o efeito e na hora, juro que parece magica queria conhecer ele a mais tempo.

Reduced my frizz, easy to apply, nice smell and feel after applying and no residue felt in morning. Quality is great if even though pricey

Great product. I immediately noticed a difference as my hair became softer and did not tangle as much.

Its not original and im so upset as i paid all this amount for a fake product
