Healthy hair is an indicator of our overall health and, like facial skin, is closely linked to how we feel about ourselves – hence the concept of ‘good hair day’ and ‘bad hair day’.

These follicles, made up of connective tissue in the dermal layer of the skin, nourish the hair and help it to grow.

It is important to give our scalps specific gentle care in order to promote both healthy hair production and our overall health and wellbeing.
