Klorane SOS Serum with Peony, $19.95.

This hair serum will be those with sensitive, irritated scalps best friend forever.

The gentle, pH-balanced formula reinforces the scalp’s natural protection, keeps the scalp moisturised and balanced, and soothes discomfort. It is non-sticky, easy to use and doesn’t require any rinsing. The serum can be applied to either towel-dried or dry hair to comfort the scalp and ensure the hair is left soft and hydrated. That pretty much says it all really.
