The Pro-Reconstructive Treatment must be used on already cleaned wires. And, if you want to enhance the result, you can start it with the Restructuring Shampoo, which is also part of the Treatment System for Chemically Damaged Hair by Natura Lumina.
The first step in the kit is to apply a small amount of Primer Concentrate to clean hair, avoiding the root. Spread the product on the hair with your fingers, without detangling. Leave on for three minutes and do not rinse.
Then, with the Primer still on the strands, apply the Lengthening Mask to the ends of the hair, avoiding the root. Untangle strand by strand with the help of your fingers or a comb and let it sit for another three minutes. Then just rinse.
The Pro-Reconstructive Treatment is able to reconstruct the porosity of the wires by up to 83%. By using it, you get more resistant, strong hair with three times less split ends.
