I have thin Nordic hair.
I have mostly used shampoo and conditioner. I used the serum a few times, but my hair looked greasy afterwards, so I have excluded it.
I have very itchy scalp in winter especially. It has been a great help to use the wonderfully scented shampoo and conditioner. Smells like mint and feels nicely cooling.
Even though I only squeeze out excess water, the ends become like steel wool. It's a shame, a big difference from other conditioners.
Now I spray on a heat protectant that also makes it easier to detangle.
