This cream is a must

I have been using only this cream for 2 years, as a night cream, sometimes for a day. Perfect feeling on the skin. Very-very hydrated and healthy skin. Strongly recommend!

Nataliia K.
Advanced Snail 92 All-in-one Cream
Worth the money

There's a bit of a learning curve with the amount you need, which is way less than you think, the scent is pleasant a bit like tea and not over powering. Works great on my short hair.

Koleston Perfect 6/ Dark Blonde Series Permanent Hair Color
Good results

I like the shampoo. It cleans my hair without stripping it. And my blonde streaks remain blonde they don't turn brassy. I will definitely be buying this again

Extreme Bleach Recovery Shampoo
Perfect for Hair Coloring and Styling

I’ve been using these Metal Duck Billed Hair Clips (6 Pieces) almost every time I do my hair. They’re perfect for sectioning my hair while styling with my Dyson and also super helpful when I apply my Sebastian Cellophanes treatment. They hold the hair really well without slipping or pulling, and they make the whole process so much easier. One thing I really like is that they’re easy to wash afterward and still look brand new. Simple but really useful clips to have.

I love Sebatian's Cellophanes

I have some gray hairs and didn’t want to start using permanent dye because I hate how obvious the roots look as the hair grows out. Sebastian Cellophanes Cranberry has honestly been perfect for me. The color fades gradually with washes, so it looks much more natural. It gives my hair a beautiful rich tone, and my grays end up looking more like soft highlights blended into my hair instead of harsh gray strands. My hair also feels really shiny and healthy after using it. Definitely one of my favorite color products so far.

Cellophanes Semi-Permanent Color Gloss
Love it!

This spray honestly makes such a difference. My hair looks fuller and bouncier without feeling stiff or crunchy. I love that the volume still looks soft and natural, especially after a blowout or loose waves. Plus, it actually lasts for hours. Definitely buying this again!
