過酸化水素&現像剤
デベロッパーはさまざまな強度があり、一般的なものは10ボリューム、20ボリューム、30ボリューム、40ボリュームです。より強い濃度の過酸化水素も購入可能ですが、髪に使うには強すぎるため避けるべきです。デベロッパーの強度はパーセンテージで表されることもあります。6%と20ボリュームは同じ強度です。

どの強さ/ボリュームのデベロッパーを使うべきですか?
10ボリューム は、染色プロセスで自然な髪色を明るくしたくない場合に理想的です。トナーやカラ―グレーズに使われます。これらのタイプの染料は「デポジットオンリー」として知られています。
20ボリューム の過酸化水素は、セミパーマネントおよびパーマネントヘアカラーによく使われます。パーマネントカラーと一緒に使うと、自然な未染色の髪を1〜2トーン明るくする効果があります。
ブリーチパウダーと混ぜると、20ボリュームのデベロッパーは未処理の髪を約5レベル明るくします。
30ボリューム のデベロッパーは色を明るくするために使われます。主にブリーチングに使用され、使用するブリーチパウダーによって約7レベル明るくすることができます。
40ボリューム は、非常に暗く頑固な髪を明るくするためのブリーチングプロセスの一部として時々使用されます。速く明るくなり、その効果は低濃度よりも強力です。40ボリュームは頭皮への使用は推奨されません。40ボリュームのデベロッパーを正しく使用しないと、髪の損傷や化学やけどを引き起こす可能性があります。代わりに、低ボリュームの過酸化水素を複数回使用することで、よりコントロールされた明るさを得ることができます。
Let customers speak for us
from 3217 reviewsCosmetic World never disappoints! They always have what I’m looking for and evidently really care about providing excellent quality products and customer service.
I was a little worried about ordering from Canada given the tariff situation and the sometimes dodgy sites selling Shades of EQ. However, everything was on-time and legit – I could not be happier!
Prompt, helpful service paired with prices well below salon RRP makes shopping here a pleasure. Orders arrive quickly and exactly as described, so you feel taken care of from checkout to unboxing. If you want reliable service and real savings on pro‑grade beauty products, this store delivers both.
Customer service that goes above and beyond. I needed to add to my order before it shipped. I was called and it was modified for me no problem. Very happy with the products as well.
The employees seem lovely and the products are authentic. They are professional and precise. I can't say enough good things! I will continue to purchase from this store.
Cosmetic World has a great variety of hair colour products. The customer service was top-notch: excellent communication and fast shipping. And the shipping was free for the products I ordered. In addition, the prices were reasonable.
Am so grateful to have found this distributor of European hair colour. Will definitely make future purchases.
Thank you Cosmetic World!
I've been using this hair color for 2 years now and no complaints! It gives great coverage for my greys and easy to mix and apply.
J'ai aimé le produit. Satisfaite du résultat de couleur
Cosmetic World was so helpful and professional. I ordered some hair dye and came within 2 days without a hitch. Thank you Cosmetic World!
Using the reasonably priced INOA hair dye I wondered if any developer would do...but this product line developer has some benefits for hair built in to this! Add to that so far I have dyed my hair Twice and still have lots left makes this a great value. I had been buying hair dye for the online mail subscription service paying a fortune and then shipping on top of that despite doubling orders which should have worked. That product faded so quickly unlike INOA which lasts even with red hair. Plus I like that as long as I do not mix this developer with the dye I can add a little more red in the summer or go a little more darker in the winter just by adding a complimentary color to go with the base and developer..saving the rest of the product for the next time needed..The bottle goes a long, long way and gives me the power to find the subtle shade differences that make me so happy I am a red head.
My order was delivered quickly and everything was as I expected.
This hair colour passed my 7 days of patch test (behind the ear), 30 minutes duration each time, without any adverse reactions. I think I have found a keeper for my ultra sensitive skin. The colour is amazing and covered all my greys. I used 10V Oxy colour with it.
My hairdresser recommended Cosmetic World to me. Their selection is superb with high quality products. I was able to find all the products I was looking for in one quick browse. The delivery fee was affordable and the products were delivered quick in a well packaged box. I highly recommend Cosmetic World to anyone looking to buy high quality and yet affordable hair products. If you can't make it in person, the delivery is a breeze!
I’ve been using Nioxin shampoo and conditioner for some time now and love it. But I want to praise Cosmetic World in particular. I discovered them just recently when I was comparing prices and they had the best prices by far, including all of the usual big discount retailers. This was my first time ordering from them and I was a little anxious about being in the US and ordering from Canada. But the shipping was not expensive and it arrived quickly and in perfect condition. I’m very pleased and will order again!
The perfect green to fade my daughter’s hair from blue teal to like green! We love anything joico!!!!!
