Perfect
7 months ago
[This review was collected as part of a promotion.] The perfect finish to any haircare routine. This leaves a glossy shine to my hair. My hair has never felt and looked so soft. It is very nourishing and revives any dull and dry hair instantly.
I used this with the hair mask, shampoo and conditioner in this range and it worked like a charm. It is easy to apply too as it is a spray that disperses an even, fine mist on the desired area.
It makes my hair feel really soft. It is not at all sticky either which is great as it means less need to wash my hair. I highly recommend this with the other products in this range as it really completes the perfect salon finish look without having to break the bank!
Yes, I recommend this product.

Diamond Sleek Smoothing Spray
7 months ago
[This review was collected as part of a promotion.] I’ve been using the Diamond Sleek Smoothing Spray and I really like it. It’s very lightweight and doesn’t make my hair greasy or heavy. I spray it on damp hair before blow-drying, and it helps keep my hair smooth, shiny, and frizz-free.
My hair looks more polished and feels softer, especially after styling. I also like that it gives heat protection, so I feel more comfortable using a dryer or straightener. The smell is nice and not too strong.
Overall, it’s a good product for everyday use if you want sleek hair with extra shine. I would definitely use it again and recommend it.
Yes, I recommend this product.

Smoothing and reduced drying time!
7 months ago
[This review was collected as part of a promotion.] Having fine hair with a natural wave/slight curve that I wash dry & straighten daily, I was excited to try the set of Keratin products. They all work very well together & do what they say! This spray is great and works well even when not used with the other Keratin smooth products. I also found that using this spray reduced the time it took to dry my hair which is both an added bonus as wash it daily and a reduced drying time, better for my hair. Would recommend this spray in conjunction with the shampoo, conditioner and mask as suggested and by itself for shiny & sleek hair.
Yes, I recommend this product.

Incredible shine!
7 months ago
[This review was collected as part of a promotion.] This Diamond Sleek Shine-Coat Smoothing Spray, with its 8% Keratin Smoothing Complex and Argan Oil, shields and smooths hair to reduce frizz even in high humidity. It works by coating the hair fibre to boost light reflection from all angles, delivering a stunning diamond-like shine. It is lightweight, non-greasy, and non-sticky which gives a natural feel without any weigh-down. It is heat-activated and provides essential protection from heat styling tools, including from blow drying and straightening. It leaves my hair super shiny.
Yes, I recommend this product.

Wonderful, shiny hair
7 months ago
[This review was collected as part of a promotion.] I tried the Diamond Sleek smoothing spray and I'm very satisfied with it. I use it after washing my towel-dried hair, it makes my hair noticeably smoother and easier to comb, and frizzy hair is visibly reduced. The shine is beautiful, but without making my hair look greasy, which is especially important to me. The scent is very pleasant. My hair feels soft after spraying, isn't sticky, and looks healthy. Of course, it doesn't replace professional straightening, but it's a really good option for daily care and neat styling.
Yes, I recommend this product.

Smells lovely, helped define my curls
7 months ago
[This review was collected as part of a promotion.] I used this smoothing spray as part of the full keratin sleek routine. I applied it after washing as the instructions say, and it smells so light and pleasent and is really easy to apply.
However, my hair is naturally quite curly and is very prone to frizz, so despite following the routine, after drying and straightening, my hair was far from sleek.
However, on my next wash, I used the products again, but rather than blowdrying and straightening as advised, I spritzed this spray into my hands and smoothed it over my curls, then let my curls dry naturally, and they had a lovely shine with much less frizz.
So if you have curly hair, I'd recommend these, as long as you are planning to embrace your curls, do not expect your curls to miraculously become sleek and straight hair though.
Yes, I recommend this product.

Heat Protection With Shine!
7 months ago
[This review was collected as part of a promotion.] Presented in a spray bottle, it delivers the perfect mist when applying all over freshly washed hair. It does state to use tension when blow drying and also sealing in the shine when using a hair straightener. I have used this with just a hairdryer, or a hair iron, anyway you use this it delivers smoothness and shine. I was pleasantly surprised my hair felt hydrated and frizz-free all day, even when it rained! A highly recommended spray for hair that seeks smoothness and shine with added heat protection!

Amazing product
4 months ago
I was gifted this through lorealistar I’ve been using Garnier Diamond Sleek for a while now, and honestly, it’s become a bit of a staple in my routine.
What I noticed straight away was how much smoother my hair looked after styling. I usually struggle with frizz, especially in humid weather, but this really helps keep everything under control without making my hair feel heavy or greasy. It still feels soft and natural, which I really appreciate.
The shine is probably my favourite part it gives my hair that glossy, healthy look without seeming overdone. I’ve had a few people ask if I’d just come from the salon, which says a lot.
I also like how easy it is to use. I just spray it on before heat styling, and it does its thing. Knowing it offers some heat protection is a nice bonus too.
Yes, I recommend this product.

Worth the price tag!
7 months ago
[This review was collected as part of a promotion.] This is absolutely brilliant, I used it after using the keratin sleek hair products but also in between washes when giving my hair a quick straighten and it looks like salon quality smoothness! The fact that this protects your hair from the heat but also gives it such a sleek and shiny appearance is crazy, its like using a hair oil but it doesnt look dirty or greasy. Its a brilliant product, a little pricey in some shops but a little goes a long way and it will last for ages so id say its worth it!
Yes, I recommend this product.

Great for a glossy finish
6 months ago
[This review was collected as part of a promotion.] I am always a bit sceptical of shine sprays because they usually just make my hair look unwashed, but this one is actually brilliant. The pump sprays a really fine mist, so you don't end up with heavily coated, sticky patches. It just takes down those annoying little flyaways and leaves a lovely, healthy-looking gloss over the top. It's become my go-to for finishing off my hair before I head out the door. Plus, it smells absolutely gorgeous and fits easily into my bag if I need a quick top-up.
Yes, I recommend this product.

Good finishing spray, better for long hair
7 months ago
[This review was collected as part of a promotion.] Designed to be used with Keratin sleek shampoo, then conditioner, then keratin sleek mask and finally diamond sleek smoothing spray so need to set aside some time to follow the process. Finally hair has to be blow dried to activate the smoothing spray. My hair was quite shiny after, but got caught in the rain a short while after and the effect was gone. Probably much better on long hair than my very short cut. However tried tgis spray after just using the shampoo and was quite effective!
Yes, I recommend this product.

Easy to apply £ lovely product but not for my hair
7 months ago
[This review was collected as part of a promotion.] I have medium length and very thick hair so blow drying it myself isn’t easy. I tried doing it but was epic fail. I felt it’s too much to do at home but would be great in salons. I would’ve loved if you could spray it to your hair after a leave on conditioner and when the hair is fully air dried you could use the straightener and see the results. Having said that, from the brief few attempts I’ve done it, it works and made my hair very smooth and shiny. So worth a try!
Yes, I recommend this product.

Diamond Sleek Shine Coat Smoothing Spray
7 months ago
[This review was collected as part of a promotion.] I have thick, wavy-curly hair that feels dry. I used this spray alongside the rest of the Keratin Sleek range and found it satisfactory for wanting that sleek look when blow drying or straightening. I use it before styling the hair and it does give heat protection from high temperatures. It is good at lessening frizz and I think that a little goes a long way. It smells great and it does leave a nice shine to the hair. I will continue to use it, so far I am liking it.
Yes, I recommend this product.

Okay Results, Personal Preference
7 months ago
[This review was collected as part of a promotion.] I’ve always been sceptical about keratin-based products after reading and hearing so many mixed reviews. I decided to give this one a try anyway, alongside the mask. I used it after the mask and before blow-drying my hair. I noticed a slight difference, but nothing major or dramatic. I also wasn’t keen on the scent of the product, which is very much down to personal preference. Would I buy it again? I don’t think so — but it may work really well for others

Fantastic results!!
7 months ago
[This review was collected as part of a promotion.] This is the last step in the Keratin Sleek system that needs to be sprayed on to towel dried hair. I have used this with both a hairdryer and a straightener and it gives fantastic results with both. It goes very well with the Keratin Sleek shampoo, conditioner & mask and it is the perfect last step for amazing shiny sleek hair. I am very impressed with the results especially as this is not sticky and does not leave hair feeling coated or weighed down.
Yes, I recommend this product.

Great 4 step routine
7 months ago
[This review was collected as part of a promotion.] Used this for the first time this morning, here are my initial thoughts. the product claims to have heat protection so great next step before styling. I did use all 4 steps of the routine and hair was sleek shiny and not flat from the root like similar products tend to do. I did still have some frizz so did need to straighten it after drying. I usually blow dry with a round brush but found it difficult to gain tension due to the hair being to sleek!
Yes, I recommend this product.

Keratin Smoothing spray
7 months ago
[This review was collected as part of a promotion.] The Garnier Keratin Sleek Smoothing Spray has become a helpful finishing step in my hair routine. I was drawn to it because I love lightweight styling sprays that help reduce frizz and boost shine, and this one mostly delivers.
The spray itself is fine and mist-like, which makes it easy to distribute evenly without leaving any buildup or greasiness. I use it on damp hair before heat styling or on dry hair when I need a quick touch-up — and I appreciate how it softens flyaways and boosts smoothness without making my hair feel weighed down or sticky.
After using it regularly, I’ve noticed my hair looks sleeker and shinier, especially around the crown and ends where frizz tends to show most. It also seems to add a subtle gloss that I really like. The scent is pleasant and light, which is a bonus if you’re sensitive to strong fragrances.
Yes, I recommend this product.

Shiny, silky, soft hair
7 months ago
[This review was collected as part of a promotion.] After using the shampoo, conditioner and mask, I assumed I would be impressed, but this surpassed all expectations! Sometimes when using products like this, my hair gets a bit sticky, which is completely counterproductive when I'm trying to get rid of frizz and make my hair sleek and silky, however, this did not make my hair sticky at all! It smoothed, it banished the frizz and it protected my hair from any heat damage. This is a total must have!

Gives the best shine
7 months ago
[This review was collected as part of a promotion.] I’ve really enjoyed using this Diamond Sleek Shine-Coat Smoothing Spray as the finishing step in my routine. It’s a lightweight, non-greasy mist that feels nice on damp hair before blow-drying. It doesn’t make my hair feel sticky or heavy, which is a big plus. Once I blow-dry my hair after spraying it on, I notice that my frizz is definitely calmer and my hair has a nicer sheen than usual. It really boosts shine and makes my hair feel sleeker.

Diamond Sleek Shine-Coat
6 months ago
[This review was collected as part of a promotion.] I have been using Diamond Sleek Shine-Coat for a few weeks and I am really impressed with the results. From the first application it added a beautiful glossy finish that instantly made my hair look healthier and more polished. The formula feels lightweight and does not weigh my hair down, which I love.
It smooths down frizz and flyaways, helping my hair look sleeker throughout the day. I also notice that my hair feels softer to the touch and looks shinier without looking greasy. It works well on both freshly washed hair and on second day styles, which makes it very versatile.
The subtle, pleasant scent is an added bonus and it does not clash with other hair products I use. Overall it feels like a lovely finishing product that enhances shine and smoothness, and it has quickly become something I would repurchase and recommend for anyone wanting glossy, well groomed hair.
Yes, I recommend this product.

Cheaper alternative to Colow Wow Dreamcoat
7 months ago
[This review was collected as part of a promotion.] This is Garniers alternative to Dreamcoat which many people with frizzy hair will have.
You apply it to damp hair, it smells of apples and then for it to work you need to blow dry your hair and ideally use hair straighteners to get the sleek look (it does contain heat protection). I liked it although can’t say my hair was completely sleek and shiny.
If you are on a budget this is a good alternative to Dreamcoat.
Yes, I recommend this product.

[This review was collected as part of a promotion.] Garnier Diamond Sleek Smoothing Spray is a solid go-to for taming frizz and adding shine without weighing hair down. It leaves my hair noticeably smoother and sleeker, especially when heat styling, and the lightweight formula doesn’t make it feel greasy or stiff. I also love the glossy finish—it really does give that “diamond” shine. The scent is pleasant but not overpowering, and a little goes a long way.

Great Product!
7 months ago
[This review was collected as part of a promotion.] I used the Keratin Sleek shampoo and conditioner first, towel dried my hair and then applied Diamond Sleek on my damp hair. I used a liberal amount of the product. and then blow-dried my hair in sections with a brush. You need the heat from a blow-dryer to activate the formula. My hair looked incredibly shiny, no fly away hairs at all - just smooth and glossy! Great product!

Gives a lovely sleek shine to my hair

Spritzed on damp hair and then activated by my hairdryer when blowdrying, it leaves my hair smooth, sleek and shiny, taming any flyaway strands whilst also protecting against heat damage. As with the other products in this range, it has a gorgeous uplifting, tropical, fruity fragrance.

Good but needs a final products to lock in

[This review was collected as part of a promotion.] The Garnier Diamond Sleek Shine Spray worked really well for me. I was able to get my hair quite straight using just a blow dryer, which really impressed me. It helped smooth my hair and reduce frizz without feeling heavy or sticky. My hair looked sleek and shiny afterwards. I just wish there was a matching serum to finish everything off, but overall it’s a great styling spray.
Yes, I recommend this product.

Gorgeous smell and good spray
7 months ago
[This review was collected as part of a promotion.] This smoothing spray smells lovely and the bottle has a really good spray action, giving a good even spritz of product. I have used it in conjunction with the sleek shampoo and conditioner. I've also used the matching hair mask. I can't honestly say it has made any difference to the smoothness of my hair and I actually find that my hair feels heavy and slightly greasy.

Just a few sprays help my strands feel smoother and look healthier. It’s lightweight and doesn’t weigh my hair down or make it look greasy. I like using it before styling for added sleekness and protection. A quick and easy finishing product that gives great shine.
Yes, I recommend this product.

Heat protectant with dazzling shine!
7 months ago
[This review was collected as part of a promotion.] This spray is an amazing multi-task product! It detangles, smooths, provides heat protection and a mirror-like shine to my hair. It is lightweight and doesn't weigh down my hair. It is also non-greasy. It has some cool technology that is heat activated, which I found unique to the product. Love it, have been raving about it to family and friends
Yes, I recommend this product.

Great spray and range
6 months ago
[This review was collected as part of a promotion.] I am loving this range. I love this reduces frizz even in high humidity. I can't believe the difference in my hair since I have been using this. My hair feels so much smoother and looks glossy. This smells lovely and is easy to use, is light weight and non greasy. I Will definitely keep using this along with the other products in this range.
Yes, I recommend this product.

Lightweight & Shiny
7 months ago
[This review was collected as part of a promotion.] Wow, this is the perfect end to hair washing routine. I was a bit dubious to start with as sometimes serum sprays make my hair really heavy, but this felt really lightweight and gave my hair a real shine but also a bit of bounce. I was really impressed and will be using this regularly. Like the fragrance and like that it’s activated by heat,
Yes, I recommend this product.

Lovely smell

[This review was collected as part of a promotion.] The Shine‑Coat spray is a standout. It gives my hair that glossy, polished look without making it greasy. A couple of spritzes and my hair looks smoother, shinier, and more put‑together - almost like a finishing spray from a salon blow‑dry. It’s lightweight, smells lovely, and adds that extra sleekness that really completes the routine.
Yes, I recommend this product.
