K18 Molecular Repair Mask is a repairing leave-in hair mask that transforms even extremely damaged hair into resilient and healthy hair. The damage can be caused by bleaching, perming, hair dyeing, other chemical treatment or heat styling. K18 Molecular Repair Mask contains a groundbreaking molecule, namely K18Peptide. This patented peptide repairs the hair from the inside out by rebuilding damaged hair and preventing future damage, frizz and split ends. In addition, it is clinically proven that the formula recovers 91% of the hair's own strength and 94% of the hair's elasticity. K18 Molecular Repair Mask consists of a delicious, light texture that feels weightless in the hair, without appearing heavy or greasy. Simply let the hair mask work for four mint teats in freshly washed, towel-dried hair, and say hello to a nourished and super soft result. Recreate smooth, strong and healthy hair with this professional hair care product that will become an indispensable product in your hair care routine! NOTE: As this is a leave-in product, it should NOT be rinsed out of the hair. Therefore, do not use conditioner in conjunction with this product.

The delivery time was exceptionally fast, and everything was just as it was described on the website. The product description on the site helped me select the perfect fragrance without having the opportunity to experience it first-hand. A beautiful fragrance and perfect gift my partner loves it and so do I. Overall a wonderful online experience, would highly recommend.

I’ve just received my 4th order from Beauty Affairs. Their range is amazing and there is always great promotions on so I don’t think I’ve ever paid full price. I love the free samples and bonus gifts. Quick delivery and on the one occasion that I had an issue with a gift card, they fixed it up straight away for me. Love this company!

I’m not really here to talk about the products although it is actually something I absolutely love right now (olaplex) and I absolutely do recommend it especially for people like me who has over stressed hair due to constantly bleaching and coloring! I finally found something to help my hair!

Love this company! I’ve made multiple orders and have been very impressed with the range of products and amazing customer service, plus the generous samples. Recently experienced a internal issue where my order was accidentally cancelled so I had to follow up to rectify. The beauty consultant got back to me almost immediately. She was so apologetic and understanding and resolved the matter promptly and professionally. It will not deter me from using Beauty Affairs in the future, I’ve recommended adore to my friends and family and look forward to my next purchase. ❤

I’ve only recently started buying from Beauty Affairs and I have to say I’m really impressed, firstly by how quickly Aubrey (customer service rep) got back to me, but also how friendly she was/is. It’s nice to be spoken to in the same kind of language that I’d use if I was working in a store, or how I’d like to be spoken to if I was walking into a store - as opposed to the inauthentic ‘chat bot’ style or the very dry online customer service that I normally get elsewhere. I’m impressed by Beauty Affair’s style thanks for all of the above. Thanks Aubrey. X

I've shopped at Beauty Affairs for a few years now without a problem, however last week my package was stolen- at the fault of the courier. I purchased around $200+ of skincare and was completely devastated when it happened, as I didn't think I would be able to get it resent or refunded because it wasn't Beauty Affair’s fault. I contacted them and to my surprise, they immediately offered to resend or refund my purchase, not only that but they included a gift! I have never had such exceptional customer service from any other company in my whole life! Knowing they are a relatively small (compared to Sephora etc) Australian owned brand makes it even more impressive and I'm so happy (even excited) to know my money is going to a company that highly values its customers. ... MoreI've shopped at Beauty Affairs for a few years now without a problem, however last week my package was stolen- at the fault of the courier.

I would encourage EVERYONE to shop here. Side note: they are also very budget inclusive with the range of products they carry which is always lovely. Thank you Beauty Affairs!!!!

I’ve received a few packages from Beauty Affairs this week, and I just wanted to say thank you so much for my products, and I love the idea of a Gifts and free express post. It is awesome! I love ordering from you guys! It is so quick and easy! In addition, you have everything I want! I was so excited when I saw on your Instagram that you stocked Chanel and La Mer, so I had to order it! Again thank you! Xx

Simply wonderful customer service. Prompt delivery, a couple of surprise goodies in every box and outstanding support when things don’t go as planned. My parcel was “delivered” by a company and I couldn’t find it for days. Anna from Beauty Affairs REPLACED it, added extra goodies at no cost and sent it via Australia Post. Anna was just brilliant. Kind, empathetic and very professional. Thank you so much to a wonderful company.

They ensured that the items were as secure as possible with some butchers paper (which is very common to use) and none of the products appeared to be damaged on the packaging, they also included a freebies, which is a nice thing that did make me want to write a review since they didn't have to do that. If I ever want to gift someone, I know some cosmetic products I will be going through Beauty Affairs.
