Miracle RepaiRx Anti-Breakage Serum

In the US, ingredients above 1% are listed from most to least. Below 1% they can appear in any order. Each note keeps three things apart: what the ingredient generally does, its role in this type of product, and what its position can tell you.

• 1 Cocos Nucifera (Coconut) Oil
  General function

  One of the few oils small enough to move into the strand, which is why it is used for pre-wash treatments. It can feel heavy or stiff on protein-sensitive hair.

  Leading ingredient

  Listed in the first three ingredients, it is likely a structural part of this formula.

  May suitDry, coarse, or high-porosity hair

  Because it penetrates rather than sits on top, it works on hair that loses water through a worn cuticle instead of only slowing evaporation from the surface the way a non-penetrating oil does.

  May suitFrizz-prone, damaged, or high-friction hair

  A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.

  May suitVery dry or highly damaged hair

  The exception to the class read: lauric acid is small and linear enough to enter the shaft rather than only coat it, and in comparison testing coconut oil was the one that reduced protein loss from washing on both undamaged and damaged hair.
