What Else You Need to Know

Everyone has metals in their hair.

• The cause: Metals erode in our pipes, mixing with our water and ultimately accumulating inside the hair fiber.

• The consequences: When metal particles mix with hair color and lightener oxidants, they can lead to unreliable color results and breakage.

• The solution: Metal Detox.

After cleansing with Metal Detox Shampoo:

1. Apply evenly on towel-dried hair and leave on for 1 minute, or 2-5 minutes for high formation hair.

2. Rinse thoroughly.

Rated 5 out of 5 by from Incredible mask! I used the mask in conjunction with the pre treatment and shampoo. When using all three together, it brought my hair to a raw state. This was a great thing. My hair felt strong and looked cleaner than it has in a very long time. The mask is not heavy and is the perfect sealer to an incredible hair system. This is now a must have product for me.

Rated 5 out of 5 by from Wonderful mask! This hair mask works wonders for build up of metals. It makes the hair soft and hydrated. Super easy to brush the hair after using it also! My clients are loving this, especially my blonde clients that turn brassy fast from hard metals in their water it’s like a sealer for the hair!

Rated 4 out of 5 by from Unsure if it works It has a light smell. It’s a nice thick cream. It doesn’t do much on the hair to help with frizz or moisture though. Not my favorite mask.

Rated 5 out of 5 by from New favorite! Loreal sent me this free sample through the BzzAgent sampling program. I’ve been loving the L’Oréal Metal Detox Hair Mask — it feels super nourishing without weighing my hair down. After using it, my hair feels noticeably softer, smoother, and healthier, especially after color services. It’s become a go-to in my routine when my hair feels dry or stressed from bleaching.

Rated 5 out of 5 by from Detox Mask The Metal Detox Mask is amazing for locking in color results. After detoxing and cleansing the hair, this mask helps seal the cuticle, add moisture back in, and protect the fresh color. It leaves the hair incredibly soft, shiny, and smooth while helping the color stay vibrant and glossy for longer. It’s the perfect final step to finish the Metal Detox routine and ensure long-lasting, beautiful results.
