The NH23 formula is unique due to its intelligent vegan technology and exclusive protein complex. This combination fills micro damage with hydrolyzed wheat proteins, repairing hair strands, adding shine, and making hair silky, smooth, and resistant to further damage.

Yes, the ingredients in the IQ Shampoo and IQ Care complement each other perfectly. The shampoo gently cleanses and preps the hair, while the care provides deep nourishment and repair, enhancing overall hair health and shine when used together.

Ensure that towel-dried hair is thoroughly saturated with NH23. The amount needed may range from 5-20ml for short hair and 20-40ml for long hair, depending on the hair's porosity. Adjust the quantity based on individual hair characteristics.

Do not apply NH23 Care on dry hair. After washing with NH23 IQ Shampoo, dab the hair with a towel and dry lightly. Then apply NH IQ Care liquid. If the hair is too wet, the liquid may not penetrate deep into the hair shaft, and the result may last for a shorter time.

This depends on the level of damage to your hair structure. During the first week of using NH23, apply it after every wash. In the second week, you can reduce the applications to 2-3 times. The general rule is to use it as long as you still see damaged hair or split ends.

During exposure time on damp hair, depending on the condition of the hair and the amount of NH23 IQ Care used, warmth can develop, which supports the hair care and repair process and gives a special feeling of well-being. Feel how your hair regenerates and renews itself from the inside out.

For the first time, try not to use any other products to explore the amazing results of NH23 on its own. IS NH23 VEGAN? As so many Marc Weiss Paris products are vegan, so is NH23. It is not only vegan, it is also color safe and cruelty free.

 Yes, it is safe to use NH23 IQ Care after bleaching, color, perming or alike.

The more treatments you do initially, the longer the shiny, healthy result will last. It also depends on the other products you use. Harsh and cheap styling products can damage the beautiful result. Look for other Marc Weiss Paris products that will complement NH23 well.

No, IQ Care should only be applied to the lengths of the hair.

NH23 IQ Care should be applied starting 1-2 inches away from the roots onto the lengths. Therefore, the recommendation for the client is to apply the product on the hair lengths, while avoiding contact with the bondings.

A) Most likely, the hair was still too wet before applying IQ Care and wasn't lightly towel-dried. When hair is saturated with water, it can't absorb any more moisture, and IQ Care can only coat the outside of the hair, limiting its effectiveness. B) The hair wasn't pre-washed with IQ Care to prepare it for application. C) The hair was pre-treated with a product containing non-water-soluble silicones, which is common with inexpensive styling products.

NH23 repairs hair from the inside out, while conditioners are typically surface treatments that can weigh down the hair. Customers with fine hair have reported very positive experiences with NH23 because it doesn't weigh down fine hair. However, please ensure your hair is towel-dried before using it!

We didn't observe any changes when using Marc Weiss Paris hair color. With some other hair colors, there may be slight color loss, particularly with fashion shades that contain a high proportion of direct pigments.

Yes, that's possible because NH23's active ingredients accumulate with frequent use in the hair. However, it's recommended to use the suggested amount for the initial treatment. Afterwards, for severely damaged hair, daily mini applications are advised. You will notice a rapid improvement in your hair structure with increased shine.
