What I Am:

The perfect “I swiped right” tale you’ve been looking for in the quest for your hair’s perfect match— finally a detoxifying, zero irritation, no drama serum that enjoys a quiet night in deeply purifying and strengthening your strands (I’ll even let you pick the first rom-com).


  • Instantly soothes and hydrates itchy and irritated scalps
  • Rebalances sebum production
  • Precise applicator for an easy application, even at the back of the head
  • Refreshing effect


Divide freshly washed hair into sections and apply two to three drops of serum to each section directly to the scalp. Delicately massage the serum with the tips of your fingers or with the Voir Scalp Massage Brush to evenly distribute it over the whole scalp. Leave the serum on, do not rinse off. Product to air dry hair or style as usual.

Why Detox?

In order to have healthy hair, you need a healthy scalp. There are several areas that we must focus on to create this fit scalp environment:  follicle detoxification, dead skin cell exfoliation, oil reduction, sun protection and anti-aging. When a scalp is soothed with a balanced ph level, similar to the skin, it will be less likely to over-produce oil and keeps the scalp clean. A clean scalp will help with turnover of skin cells and promote healthy hair growth.

Detox is not simply just washing the scalp like shampooing, but to use a product that actually helps clean out the oils, dead skin cells, and any other residue that could be clogging your hair follicles. The difference between shampoo and detoxing is that shampoo focuses more on the hair rather than the scalp. It is recommended to detox your scalp once every 4-6 weeks.
