Q&A

Q. There have been a lot of issues with hair dye recently, so I am worried about the ingredients. Is it safe?

A. The product has completed a functional report for hair dye with the Ministry of Food and Drug Safety, and tests have been conducted on 19 substances of concern* for scalp and hair. It has been confirmed as 'not detected.'

* Benzophenone-1, Benzophenone-3, Benzophenone-4, Benzophenone-8, Ethanol, Triethanolamine, p-Hydroxybenzonic acid, Methylparaben, Ethylparaben, Propylparaben, Butylparaben, Isopropylparaben, Isobutylparaben, Acetate, CMIT, MIT, SLES, SLS, ALES, ALS

Q. Do I need to rinse with shampoo after use?

A. This product contains cleansing ingredients, so it is safe even if you do not use shampoo separately.

Q. Can I use it daily?

A. Yes, it is safe to use daily. However, since this is a product with excellent and long-lasting hair dye effects, we recommend using it according to the user’s hair dye cycle.

Q. Is it okay to perm or straighten my hair immediately after dyeing?

A. It may not give the desired results. We recommend spacing about a week before proceeding.

Q. Are there any allergic reactions?

A. Allergic reactions may occur depending on the skin type. Also, sudden allergic reactions may occur due to changes in body constitution. Therefore, please make sure to perform a patch test before using the product.

Q. When I try to use it, a black liquid flows out like water. Why is that?

A. The contents on the spout side may react with oxygen and flow out. This is a natural phenomenon, so please discard the reacted contents and pump again before use.

[Image: Illustration showing how to store the product packaging in a zip bag or wrap the spout with vinyl and tie it tightly with a rubber band.]

To prevent this phenomenon, please store the product by putting it in a zip bag or wrapping the spout with vinyl and tying it tightly with a rubber band.
