BioKeratin Advance Shampoo! Step 1 of our revolutionary formula is designed to give you a deep cleanse that goes beyond the ordinary. Not only does it remove the natural oiliness of your scalp , but it also gets rid of any residue from hair products such as gels, foams, dry shampoo, serums and more.

With the power of Step 1 Shampoo , we guarantee a total cleanliness that lays the foundation for the success of a 100% perfect straightening. It is crucial that your hair is impeccably clean so that the active ingredients of Step 2 are optimally absorbed by each hair strand. Remember that the key to a long-lasting and spectacular straightening lies in this essential step!

Important! Don't underestimate the importance of Step 1: if impurities remain in your hair due to the omission of this previous step, the result will not be optimal and the duration of the straightening treatment will be compromised. Don't let anything stand between you and smooth, radiant and impressive hair. Make BioKeratin Advance Shampoo your ally to dazzle with impeccable keratin!
