UK Scalp Care Tips

Tackle Hard Water: Much of the UK (especially Southern and Eastern England) has hard water, which causes mineral deposits that trap oil. Rotating in a clarifying formula like OUAI Detox once a week breaks down mineral build-up.

Double Cleansing: Apply a small coin-sized amount to break down surface grease on the first wash, rinse, and follow with a second lather to deep-clean the scalp pores.

Condition Roots-Free: Always keep rinse-out conditioners restricted from mid-lengths to ends.
