过氧化物和显色剂
开发剂有不同的浓度,常见的有10体积、20体积、30体积和40体积。可以购买更高浓度的过氧化氢,但它们对头发来说太强,不应使用。开发剂的浓度有时以百分比表示。6%和20体积是相同的浓度。

我应该使用什么强度/体积的显影剂?
10体积 在您不希望染发过程使自然发色变浅时使用是理想的。它用于调色剂和色彩光泽。这些类型的染料被称为“仅沉积”。
20体积过氧化氢通常与半永久和永久染发剂一起使用。它在与永久染发剂一起使用时,可以对自然未染的头发产生1到2个色调的漂白效果。
与漂白粉混合时,20倍显色剂将使原生发色浅化约5个色阶。
30倍 显色剂用于提亮颜色。它的主要用途是漂白,具体可以根据所使用的漂白粉提亮大约7个色阶。
40体积 有时用于在漂白过程中提亮非常黑暗、顽固的头发。它的漂白速度快,效果比低浓度的更强烈。40体积不建议用于头皮上。使用40体积的显色剂如果不正确使用可能会导致头发受损和化学烧伤。相反,使用多次低体积过氧化氢的应用将允许更可控的漂白。

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!!!!!
