You may have heard of Kat Burki when it comes to luxury skincare, but now the brand has officially expanded into haircare with this new Kat Burki Shampoo and Conditioner with Bio-Ferment Renewing formulations. I have been testing them out. Here’s what you need to know.
What is Kat Burki Bio-Ferment Renewing Shampoo & Conditioner?

These new Kat Burki Shampoo and Conditioner haircare products are designed to transform the health and vitality of your hair, rooted in the same clinical approach that brand uses for their skincare. The aim is to deliver results that go beyond surface shine to genuinely restore hair and scalp health over time.

My Experience with the Kat Burki Shampoo and Conditioner

From the very first use, I found the Bio-Ferment Renewing Shampoo to be super soothing and gentle on my scalp. The creamy lather feels luxurious yet doesn’t strip the hair, and instead, it leaves my scalp feeling balanced and refreshed.
The Bio-Ferment Renewing Conditioner is equally impressive. It leaves my hair incredibly soft and tangle-free, so much so that I can comb through immediately after rinsing without needing any detangling spray or leave-in treatment.

Perhaps most impressively, the duo seems to keep my hair looking and feeling clean and fresh for much longer than usual, which makes it a game-changer for anyone trying to extend the time between washes without sacrificing style or volume.

Final Verdict
The Kat Burki Bio-Ferment Renewing Shampoo & Conditioner feel like the haircare equivalent of a luxury skincare ritual. They not only deliver immediate softness and manageability but also work in the background to improve scalp health, hair strength, and long-term resilience.
Top Tip: I love to use a scalp massager with the shampoo to really work it into the scalp.
If you already love Kat Burki’s skincare, this is a natural extension of the brand’s results-driven philosophy, and if you’re new to the brand and love serious haircare, the Kat Burki Shampoo & Conditioner is a good place to start.
