Kerastase Genesis Shampoo Causes Oily Scalp
I purchased Kerastase Genesis Shampoo from the brand’s official seller because I was struggling with hair loss and dullness. After using it for just one week, I noticed a major issue—every time I washed and dried my hair, my scalp became excessively greasy. Hoping to get expert advice, I reached out to the seller through the "Ask a Question" section, since Kerastase has no customer service number available. Instead of real help, I got a dismissive response: "No, the shampoo does not cause oiliness." If Kerastase is truly a professional brand, where is their product expert to assist customers?
