1 weekVerifierad testareSomething to have in the routine ✨
A little about my hair, I have thick colored hair from a few years back and hair that lately needs a bit more nourishment and support. I'm also losing some right now. We who live in southern Skåne have a lot of lime in our water, so we really need products that work against that! Very interesting product! I like that it should be used before shampoo and also in conjunction with the shampoo so you don't have to rinse twice. It's a transparent serum that is applied to the hair. I find that you need to have the hair a bit more on the wet side before applying it and that it still requires a fair amount of product. I perceive the scent as citrusy and not like other shampoos that are sweet/flowery. It's a lovely serum that comes in a pump bottle, which makes it easy to dispense. The products in the series can be used individually and do not need to be in conjunction with the rest of the series, which means you can choose which part you want. This serum should be used for the first 5 washes and then as needed 👌 The only downside is that the product is expensive! I think my hair stays between washes almost a whole day longer and I absolutely think it has more shine and feels healthier ✨ #LYKOINFLUTESTER #KERASTASE14 likes1738 viewsCharlotte

14 hoursVerifierad testareBest pre-shampoo!!😍
This pre-shampoo from KERASTASE is truly a tip for you who want to feel that your hair gets a proper wash, while also getting an incredibly shiny result! I have used the entire series and I feel that my hair has been strengthened, and I definitely notice a HUGE difference in the shine my hair gets from this series!!!! I have tried many different pre-shampoos, but I have experienced that they almost become drier and of poor quality.. MEEEEEN with this, it’s like seeing a whole new world!😍 Besides giving shine, I really feel that my hair feels stronger, and I see significantly fewer broken hair strands when I, for example, brush my hair, straighten, blow-dry, style. There’s hardly anything at all, which I would say is because of this series! Builds up, strengthens, gives shine, light hair, fullness, clarifies your color/toning as it removes lime! Recommend 10/10 bottles!!😍 #LYKOINFLUTESTER #KERASTASE #HAIRTIPS #HAIRCARE #LYKO #KERASTASELOVE6 likes662 viewsSotnosen

16 hoursVerifierad testareA product that works
As a #lykoinflutester, I have been tasked with testing this pre-treatment. My hair is thin and fine, but dry and needs lots of moisture, while products with a lot of moisture often weigh it down, so I often have a hard time finding the perfect products. This pre-treatment is supposed to remove product buildup and lime from the hair. We have our own well with lots of lime, so I was really looking forward to testing this product. The consistency is quite thin and easy to distribute in the hair. You need to use quite a bit, but it feels okay since it doesn't need to be used every time. The scent is heavy and a bit musky. It smells like a perfume store, so if you're very sensitive to scents, I wouldn't recommend it. Together with other products, it becomes very strong, and you can smell it for several days. Fortunately, the product can be used with other products, so I've used other shampoos and conditioners while testing it, and it works great, and the scent isn't as strong. Shampoos usually lather very little when the water is hard, but after using this, you get a lovely lather, and the hair feels super clean. The only downsides are the price and the scent, but overall, it's really a product that works! #kerastase10 likes1169 viewsEmilia

1 weekVerifierad testareCleanses the scalp well before washing✨
A pre-shampoo treatment that is a unique pre-treatment that can really make a difference for your hair.🌠 This treatment is designed to remove product buildup and impurities from the scalp, providing a cleaner base before you wash your hair.🤧 The consistency is light and gel-like, and I like to apply it to the scalp and massage it in before I use shampoo. After the treatment, I feel like my hair becomes lighter and airier, and the shampoo lathers better! Lots of lather actually!! I use shampoo from the same series🙌🏻 The pre-shampoo also helps improve hair health by preparing it with the other products in the same series like the mask or conditioner.🌟 Using this pre-shampoo treatment can really transform your hair care routine, especially if you have a lot of product in your hair from styling. Or need a good scalp cleanse. Overall, this is a great addition to my hair care routine to achieve healthier and more radiant hair.💖 #LYKOINFLUTESTER #KERASTASE #shampoo #haircare4 likes1443 viewsto leave a commentSannu
