Why Asian Stylists Recommend It
Dry indoor heating and hard water abroad often push Asian scalps from balanced to flaky, and a dry-scalp shampoo is the simplest correction.

Best for
Normal to dry scalps dealing with itch, flakes or odor who also want a thinning-focused wash.
Avoid if
Skip it if your scalp is genuinely oily by midday — a dry-scalp formula will not clear that.
Why we recommend it
RYO Hair Strength Expert Care is a daily shampoo positioned for normal and dry scalps rather than oily ones. It targets the everyday complaints that come with a dry scalp: flaking dead skin, itchiness and lingering odor between washes. The line is also marketed toward thinning hair, so it sits in the scalp-care lane rather than the repair lane. Treat it as a cleansing base and layer a mask or leave-in separately if your lengths are damaged.
