We make it. Now we sell it here.

G-Flow makes the GDS Hair Dye Shampoo in Korea. The agreement that put it in an outside shop has ended, so it is sold here now — same line, same formula, same three shades. Shipped from Korea and tracked, with the rate and any duties we collect shown before you pay.

How a product earns its place

Nothing gets in on marketing.

Every product goes through the same three steps — and we publish what we find, including where a pick falls short.

  1. 01Screened

    We read the ingredient list first.

    Every formula is graded ingredient by ingredient against public safety data — the risk level, what each one is there to do, and what the formula leaves out.

  2. 02Reviewed

    Then we check it against real use.

    We read what buyers actually report — what worked, what didn't, and who it wasn't for — and weigh that against what the label promises.

  3. 03Awarded

    Only then does it stand next to the category #1.

    We put every pick beside the best-seller on Amazon and Olive Young, and show the gap — whichever way it falls.

Screened, not sponsored

No brand pays for a place here. Every score, every benchmark and every flagged ingredient is published on the product page.

Read before you buy

Every ingredient, before any claim.

Open any product and you'll see the same thing we use to decide: every ingredient, its risk level, what it's there to do, and what the formula leaves out.

The screening list

Fewer emails. Only what's worth it.

New formulas we've screened, which products just won an award, and the occasional restock. That's it.
