Scalp first
Healthier scalp, thicker-looking strands
When the scalp is congested with build-up and excess oil, strands grow finer and weaker. Clear it away and rebalance the scalp, and those same follicles can support stronger, thicker-looking hair. That's the difference the Wash System is built to make, every time you wash.

Inside the follicle
Healthy hair starts beneath the surface
Every strand grows from a follicle rooted in your scalp. When the scalp is clean and balanced, the follicle stays clear and the root can produce a thick, strong strand. When oil and build-up clog it, hair grows finer and weaker over time. The Wash System is built to keep that whole environment clean, so your hair grows from the healthiest possible base.

I was sceptical, but wow
I was hugely sceptical about it, but hey presto, it's working. I was thinning more than balding, but it took just 3 months for hair texture to feel thicker and it's improving steadily all the time. Very impressed.
