过氧化物与显影剂
显色剂有不同强度,常见的有10倍、20倍、30倍和40倍浓度。虽然可以购买更高浓度的过氧化氢,但它们对头发来说过于强烈,应避免使用。显色剂强度有时以百分比表示,6%和20倍浓度是相同强度。

我应该使用什么强度/浓度的显色剂?
10倍浓度 适合在不想让自然发色被染发过程提亮时使用。它用于调色剂和色彩釉剂。这类染料被称为“仅沉积型”。
20倍浓度 过氧化氢常与半永久和永久染发剂一起使用。与永久染发剂配合使用时,对自然未染发可提亮1至2个色阶。
与漂粉混合时,20倍浓度显色剂可将未染发提亮约5个色阶。
30倍浓度 显色剂用于提亮颜色。它主要用于漂白,根据所用漂粉不同,可提亮约7个色阶。
40倍浓度 偶尔用于漂白过程中提亮非常深色、顽固的头发。它提亮速度快,效果比低浓度更强烈。不建议在头皮上使用40倍浓度。若使用不当,40倍浓度的显色剂可能导致头发损伤和化学烧伤。相反,使用多次低浓度过氧化氢可以实现更可控的提亮效果。
Let customers speak for us
from 3232 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!!!!!
