I have short, thin and oily hair. I use Olaplex -3 once a week, then shampoo 4C, then mask 8. I wash it daily with Aveda Rosemary Mint shampoo, L'Oréal Professionnel Absolut Repair Serie Expert as a hair mask. In addition, I apply The Ordinary Hair multipeptide hair thickening serum daily. Once a week a scrub. I have never used Björn Axén cosmetics, but there are many good reviews on these products.I hope I can win one and share my opinion.
