For customers of the GDS Hair store
DHALIORA

The GDS store is closed.
The product isn't.

We can't sell it under the GDS name any more — but the shampoo itself never changed. Same makers in Korea, same formula, same bottle. It's here now, and here is Dhaliora.

WHAT HAPPENED

The store you used to order from is gone, and the GDS name went with it. There's another party involved, so we'd rather not tell only our side of it in public.

That's the whole of it. It was only ever a name. Nothing happened to the shampoo, or to the people in Korea who make it.

Losing a name didn't have to mean losing the product — it meant finding somewhere else to sell it. Dhaliora is that somewhere. A shop of our own, so the thing you've been using can keep reaching you.

WHAT TO ORDER

Same bottles, two sets of names.

These shampoos have always been sold in Korea as well as abroad, and the two markets have always used different names for them. Neither set is the real one and neither is a stand-in — they're the same bottles, from the same makers, wearing whichever name belongs to the shelf they're on. What you'll receive from us is the Korean side of that pair.

Couture Deep Brown

Black goes by the same name on both shelves. The browns are made under Couture and carry that name at home — which is the only reason two brands appear here at all.

SEE FOR YOURSELF

Both bottles, one photograph.

Not two pictures taken separately — one frame, both bottles standing together, so there's nothing left to wonder about. The label on the front is the only thing that differs.

INGREDIENTS, LINE BY LINE

Nothing to spot the difference in.

Every ingredient on the bottle you used to buy, set against every ingredient on the one we'll send, in the order they're declared. Declarations are regulated in Korea and can't be reworded at will — which is what makes this worth checking rather than just reading.

QUESTIONS

What you're probably wondering.

Is this really the same product? +

Yes. Same makers, same formula, same bottle, same size — for every shade. The ingredient lists above are the ones printed on the packaging, and they match line for line. Hold your old bottle up against them.

Why can't you use the GDS name any more? +

There's another party involved, and we'd rather not tell only our side of it in public. What we can tell you is that it only ever touched the name — not the shampoo, not who makes it, not what's in it.

Why do the browns say Couture? +

Because that's what they're called in Korea, and always have been. Black happens to go by the same name in both markets; the browns don't. Two names for one bottle, one for each side of the world.

Why is the label in Korean? +

These are the Korean-market bottles. That's also why every ingredient is set out in English above — so you can read exactly what's in the one you're holding.

Brown and Dark Brown have the same ingredient list. Why? +

Because they do — the two shades share a formula and differ in how much of each dye component goes in. A declaration names what's in the bottle, not how much, so the ratio doesn't appear. Same ingredients, different mix, different result on your hair. This was true of your old bottles too.

What happens to my account and order history? +

Accounts don't move between stores, so you'll need to create one here. Use the same email address and we'll match your past orders, carry your status over, and put the $10 credit on the new account.

I still have a bottle from before. Can I use both? +

Yes. Same formula — use them in any order.

How do I get the $10 credit? +

Sign up with the same email address you used at the old store. The credit will be on your account when you reach checkout — there's no code to type in and nothing to apply for.

The label is different.
The people making it aren't.

All three shades. Same as they were.
