Act+Acre

New York, USA · Founded by Helen Reavey & Colm Mackin · Founder-led

Cold-processed, scalp-first haircare formulated by a trichologist.

Why it matters

Launched 2019; pioneer of the ‘scalp care = skincare’ category narrative now dominating prestige haircare. Cold Processed Scalp Detox is the hero SKU. Reference case for clinical-credentialled (trichologist-founded) haircare scaling at Sephora with a defensible technical story.
