First I am very satisfied with the company that delivers the product in Poland. The team confirmed via email in French or English, the receipt of the order, the departure of the parcel and is interested in feedback. He was also very well packaged which avoids surprises for a cream. Excellent business management. The great product !! I had already tried a sample and I loved ... the hair growing in brightness, softness, shine. They are much less relaxed and dull. I recommend this mask without hesitation. The price also excellent for a good quality product.
