Purchased product at the end of August. Complete waste of money and absolutely no results. Got the conditioner, hair serum and hair mask. Hair mask did earn 2 start but the rest of the product is waste. The hair serum doesn’t even come out with the help of pipers. And the conditioner makes the hair more dry and fizzy. I got influenced by the influencer who advised it, but never again.
Hi, For the past two days I’ve been trying to send an email to your support, but it says that your inbox is full and cannot receive my message. This makes me a bit concerned about whether you have received my order? Kind regards, Silwia Østergaard
