    Moisturizing serum!

    I've had problems with dry and frizzy hair and have been testing this serum for almost two weeks. I've used it both at night as a "mask" and during the day on the lengths. My hair feels much softer, shines more, and is less dry!! I really recommend it, especially if you have dry hair in need of moisture! The only downside I would say is the price - BUT the product is economical, so keep that in mind. I use one pump for all my hair, which is very long and thick.

    A flop for my hair

    I had high hopes for Redken Acidic Bonding Concentrate, but unfortunately, it did not live up to my expectations. The packaging is really nice and feels exclusive, which makes the product tempting to try. However, I was not satisfied with the product itself. For starters, I thought the scent was way too strong and felt quite chemical, which was not pleasant. As for the results, I felt that the product made my hair drier rather than providing the moisture I had hoped for. I noticed no significant improvement in the hair's structure or elasticity. In summary, despite the nice packaging, I was not impressed with Redken Acidic Bonding Concentrate. The review was conducted on behalf of Smartson - the test pilot received the product for free.

      Hi Alexandra! 😊 Thank you for your review! So sorry that the product didn't meet your expectations 💗 If you find that your hair feels drier, it might be worth applying a smaller amount or using it together with a moisturizing product, like a leave-in cream or hair oil. Have a really nice day! 🌞

    Can it be used before blow-drying?

    Hi. Is it heat protection/can it be used before styling with heat tools/blow-dryer?

      Hey 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.

    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!

    Moisturizing and good scent!

    I have tried this product for 2 weeks, and I notice that my hair ends have become much stronger! Smells good, and I who have curls absolutely think it made a difference! But I think I need to use it for a longer time to see a bigger effect :)

    Can be used over time

    I am very satisfied with the product, although the initial scent may seem somewhat intense. Fortunately, it disappears after about 10 minutes. For optimal styling, I recommend applying 2–4 pumps before styling and an extra pump after the hairstyle is set. The product reduces frizz and gives the hair a radiant shine, especially when used in combination with Colorwow Dreamcoat, which provides a long-lasting, fresh, and shiny finish. The packaging is practical and travel-friendly – the pump can be locked, it doesn’t leak, and therefore it’s perfect to take on vacation. It’s important to note that the product requires a bit of time before you see the full effect. After just one week of regular use, you may not notice any immediate results, but over time you achieve the desired effects. I have also found that the product works excellently on colored hair. By combining it with weekly use of purple shampoo, the color stays fresher, despite the fact that styling can often lead to some color loss and reduced shine. After using the serum, I find that the color holds better and lasts longer. The review was conducted on behalf of Smartson – the tester received the product for free.
