Rated 4 out of 5 by from Solid detox line. This is a decent detox product. I wish it had a bit more lather but I can definitely feel the difference in the hair after using the full system. I might pick this line up for my back bar.

Rated 5 out of 5 by from Product on point This product is on point. I can instantly feel the hair detangling in my hands and the hair feeling silky and smooth. I then followed up with the shampoo and conditioning treatment. When I blew out the hair it felt clean and healthy.

Rated 4 out of 5 by from pre-treatment shampoo I received this product for free for my honest review. It isn't my favorite pre-shampoo treatment but does do fairly well with the system. I prefer the pre-treatment spray over the pre-shampoo treatment. However, it did seem to add into the hair feeling extra fortified and giving it a little added boost to help with the overall health of the hair. It seems to be better on medium to coarse hair and not so much on fine hair.

Rated 5 out of 5 by from A Good Detox It is an interesting product for sure. it is really beneficial for those that want a quick in the bowl detox treatment instead of one before a color treatment. My clients love how their hair feels after we do this treatment is done. it provides shine and softness in ways other treatments haven't. Most of my clients do have thicker hair, so I have to sometimes have to use more than usual. but other than that it smells amazing, and doesnt effect color espcially the red hair color cleints I have.

Rated 4 out of 5 by from Staple This line works very well and is always on my backbar. I get consistent results and it helps prep the hair for color.

Rated 5 out of 5 by from Thick and not oily I really loved the light yet moisturizing consistency of the pre shampoo, it made de tangling the hair easier. The bottle set up to four pumps for one section however, I felt like 1 to 2 pumps was more than enough for a medium length hair.

Rated 5 out of 5 by from Great for porosity issues This is a great product to use to even porosity before toning or before vivid colors. My vivids came out even and consistent. I did receive this product for free.

Rated 4 out of 5 by from Great first step in detoxification I really enjoyed this first step in the metal detox process. There’s a bit of a learning curve when it comes to using the right amount and I never really got much of the “lather” that the product said it would have, but I feel like it helped in the overall positive outcome when used along with the shampoo and after treatment. I have since used just the shampoo and after treatment without this product and still got great results, but this product gives a bit of an added bonus when it comes to a deeper detoxification.

Rated 5 out of 5 by from Great for prior shampooing I love how this helps keep the hair clean way longer than just using shampoo. A pre shampoo prior to the shampoo is wonderful for oily scalps. It also helps with. Breakage and hard water in peoples showers.

Rated 5 out of 5 by from Easy to use! This pretreatment is so easy to use. I could tell that it instantly made my jar feel more manageable and left my hair so shiny and clean feeling. I’m so excited to be able to use this on clients with hard water before color services. I love the fact it only sits on the hair for 1-2 minutes! So great! Smells amazing!

Rated 4 out of 5 by from Amazing metal detox system I really enjoy using this product line. The product does say to work it into a lather and I find to get it to any sort of leather. You need to use a really large amount of product. I really enjoy the smell and I really enjoy the outcome.

Rated 5 out of 5 by from Amazing add on service! Love this whole set!! I have a client I offered this service to we started with the treatment and then the shampoo and then the deep treat. The hair felt smooth, soft, and deeply repaired even by the shampoo! The end result was a wtone free of yellow and hair that was full of body and shine! Would highly recommend adding the service to your salon offering

Rated 5 out of 5 by from Made hair feel smoother L’Oréal sent me this free sample through the Bzzagent sampling program in exchange for my honest review. This preshampoo is meant to be applied to wet haor. After sectioning my hair in 2 sections I applied 2 pumps per section and left it on for 2 minutes. It made my hair feel smoother by filling the hair and sealing the cuticle. Since it lowers the porosity of my hair it helps to prevent future heavy metal buildup over time. It is easy to use and doesn’t add too much time to my hair care routine.

Rated 4 out of 5 by from Great product Loreal sent me this free sample through the BzzAgent sampling program. I really like the L’Oréal Metal Detox Pre-Treatment Spray because it makes my hair feel stronger and more protected before coloring or lightening. It’s lightweight, easy to apply, and doesn’t leave any residue or heaviness. I’ve noticed more even color results and less dryness or breakage when I use it, which makes it feel worth adding to my routine.

Rated 4 out of 5 by from I really love this! Out of all the products I’ve received from bzzagent and salon centric review crew this might be on the list of my favorites, especially when you pair it with the complete system. It leaves the hair feeling so healthy and soft. I’ve not only used this on my hair but on my clients and hands down would recommend to anyone who wants to try it!!!
