What is reverse hair washing and why does it work?

Why does it work?
If you use the products in this order, excess conditioner residue will be removed, resulting in amazingly thick and voluminous hair.
How to do it right?
Reverse hair washing takes place in 4 steps: thorough wetting of the hair, exposure of the conditioner for 5-10 minutes, washing the hair with shampoo, creating large, thick foam, and rinsing the hair.
A couple of tips from experience using this technique for the first time: always make sure your hair is completely wet before applying conditioner. It is also important not to rinse out the conditioner before applying the shampoo. And, finally, you can apply the conditioner a second time, but only at the ends, because otherwise you risk making your hair heavy.
You can also wash the trimmed hair using hair oils and masks, when you especially want to nourish your hair.
