PHS Hairscience ADV Elixir, $238

This smooth and runny exfoliant is packaged in a glass bottle with a dropper, which makes dispensing more hygienic. It soaks into the scalp without any oily residue and smells like fresh berries. Once you’ve applied it, the scalp tingles a little, like a cooling menthol sensation, and you need to massage it into the skin for 10 minutes. It rinses out easily and I do feel that my scalp is smoother. The product also has anti-inflammatory and anti-bacterial properties, thus improving scalp health and hair growth over time. Tip: follow up with the ADV Repair Hair Mask ($120) for super smooth, shiny and thicker feeling lengths.
