British hair care brand Hair Syrup has gained market traction in the UK, driven by the recent popularity of its pre-wash oils across the social media platform TikTok. The brand offers ten pre-wash and leave-in oils designed to address various consumer hair and scalp concerns, including dry ends, scalp imbalances, hair thinning, breakage, and frizz. It also claims to support hair regrowth as part of post-extension care.
