Wow
It’s rare that I fall for a product right at the first use. I actually didn’t have such high expectations for this, but WOW! ➕ The bottle has a handy pump function that makes it easy to dose the product. ➕ The scent is fresh, a bit tangy but not strong at all. I think this works well even for scent-sensitive people. ➕ The serum provides good moisture without weighing down or making the hair greasy. ➕ The hair becomes shiny and free from frizz. Additionally, it brings life to my tired straight hair (which gets curly when it feels good and is treated gently) so that it’s not pin straight. #lykoreview - Most helpful negative3 monthsRating: 2 out of 5
No home run
I have tested the Redken Acidic Bonding Concentrate 24 / 7 Night & Day Serum for just over a week. My hair is medium thick, bleached with blonde highlights, a bit dry, and gets frizzy easily. I like the practical pump bottle that the product has, it's easy to get the right amount out. I take about 1-2 pumps per use and scrunch it into the lengths. I am sensitive to scents and easily get migraines from strong fragrances, but the serum has a mild and pleasant scent that just feels fresh, without being overpowering. I really appreciate that! I have tested the product mainly on dry hair but also a few times on wet hair after washing. The serum has replaced my hair oil that I usually take a pump of in the evening before bed, and I can feel a difference. Unfortunately, not for the better. The product is supposed to provide up to 3 times more moisture, add shine, and reduce frizz according to Redken, but I notice none of that. My hair is rather drier than usual and the shine I used to have has disappeared. I also find my hair to be more frizzy than usual. The only thing I have changed in my hair routine is the serum, so unfortunately, it is the culprit in this drama. The serum costs 559 kr and it is expensive, especially with the lack of effect that I experienced. It is not a product I can imagine buying again, as it did not suit my hair at all. But now it will be passed on to a friend who has a completely different type of hair, hopefully, it will suit her much better.2403 views- 3 monthsGreat review and super honest picture 🥰 too bad the product itself wasn't better, but good for us others to know 🤗1 likes

Question?
Hey! I’m pretty confused about my hair (not confused) but I dyed my blonde hair brown and turned it back so now it’s blonde again, it took time but I’ve still bleached it myself until I thought it looked good. My hair is also a bit wavy in itself and needs a lot of moisture, and considering that it’s damaged and needs even more moisture, I wonder if this is worth trying in conjunction with the shampoo and conditioner? Asking because these products are quite expensive, does it provide moisture? Will it help with moisture? I have high porosity hair with a touch of medium porosity. Is this a good product then?🌟⭐️235 views- Hairdresser at Lyko1 weekHey Sanne! 🌸 Since your hair is bleached and wavy, this will be a really good complement. It helps to strengthen the hair, moisturize, and reduce frizz, while also repairing damaged hair. It works together with the shampoo and conditioner and can be used both day and night on dry or damp hair 👌🏼🥰 Have a nice day ☀️

Citric acid and dark colored hair?
I got a little curious about this series since I've read a lot of good things about it. So I've been using this product (also shampoo, conditioner, hair mask, and a leave-in cream) for a few weeks. I may have experienced that my hair feels a bit better and softer, so that's good. But suddenly the color in my hair is fading much faster. It colors dark brown that leans towards reddish-violet. And suddenly the lengths and ends turn orange in no time. I wonder if it could be the acid in these products that pulls the color out more? Okay that it's summer and the sun is doing its part. But I've had the same hair color for several years now, and I haven't experienced the color fading this much in previous summers.380 views- Hairdresser at Lyko1 monthHey Emma! 👋🏼 The Redken Acidic Bonding line is actually designed to protect colored hair, not to pull the color out. It works with a low pH value to close the hair strand's cuticle and thereby better encapsulate the color, not the other way around 🤗 However, sun, heat, and frequent washing can be real color thieves, especially when the hair is already colored in red-purple tones that tend to fade more easily. If you've washed your hair more often, been in the sun more, or maybe used heat tools more frequently lately, that could be the reason 😅 If you want to keep the color depth longer, it can help to complement with a color-preserving UV protection or a color mask that refreshes the shade between colorings 🌸 This UV protection is my favorite ☀️ lyko.com/sv/suntique/suntique-i-m-hair-sun-treatment-100ml Take care 🦋

Can it be used before blow-drying?
Hi. Is it heat protection/can it be used before styling with heat tools/blow-dryer?1166 views- Customer service at Lyko4 monthsHey hey Yasemin🌸 This serum does not contain heat protection, so I recommend you complement it with this spray on top of the serum to protect your hair from the heat of your styling tools 🥰👇 lyko.com/sv/redken/redken-styling-one-united-150ml-1 Good luck and take care of yourself!

Good serum
I have used Redken Serum for a week and am quite satisfied with the results. First of all, it has a wonderful scent that really makes the application a lovely experience. The serum gives a nice shine to the hair and makes it soft and shiny without weighing it down. However, I haven't noticed any significant difference compared to other serums I've tried before. It feels like a good alternative, but not really something that stands out significantly from other products in the same category. It's definitely good for those looking for a wonderfully scented serum with shine, but maybe not the most revolutionary on the market.

Moisturizing serum
I have used the product for 2 weeks. During this time, I have not noticed any long-lasting effect. When using the product, the hair becomes softer and shinier. But if you don't apply it, the effect disappears. I liked the scent and consistency. The product does not weigh down the hair and does not make it greasy.

Great for dry hair!
The packaging is really pretty and gives a luxurious feel. I've struggled with dry and frizzy hair and have now been using this serum for over two weeks – both day and night on the lengths. The result? My hair feels significantly softer, shinier, and less dry! I can really recommend this serum, especially if you have dry hair that needs moisture. The price is a bit steep, but since the product is very concentrated, it lasts a long time and you get what you pay for.

Works flawlessly!
My daughter and I both had mega dry and scratchy hair after we moved, as the water here is mega hard on the hair. We have used the product for 15 days, it worked on my hair after 7 days where I could see a change, my daughter's hair took a bit longer before you could see a difference! The hair is not scratchy anymore. It is wonderfully soft and shiny. I am totally hooked on this product But all in all, mega good product. Works as it should, extra plus it smells sooooo good!

Redken - super great product
I think this product was absolutely amazing. I've been testing it for about 2 weeks. It completely locks in frizz. Good consistency, easy to work into the hair. I always blow-dry my hair after applying the product to wet hair. The hair becomes easier to manage and smooth. It also feels thicker. I usually spray a bit of saltwater too. The price is totally okay when you think about how economical the product is and what results it gives.

Caroline
I have been testing this for 3-4 weeks now. I usually have very dry - normal hair. I also dye my hair very often. I noticed right away that it made my hair much less frizzy. You get incredibly soft and shiny hair from it. This is the first hair product I have tested that doesn't make my color bombs leak. I love the scent of it, there’s nothing bad to say about it. Could be a little cheaper but otherwise completely perfect!558 viewsto leave a comment
