I buy all my hair clips at Cosmetic World in a package. Great value, better price than anywhere else including the dollar store. One hair clip will last 1-3 years
Sometimes I just buy a hair product at Cosmetic World without shopping around because I know their prices are better than other shops. The staff is knowledgable about hair colour too.
Everywhere I go people compliment my hair colour, including strangers that walk past me. I mix 7:00 medium blond Igora Royal to cover grey with 7:57 copper blond (nice orange/gold colour, not reddish). With 20% developer to cover grey. It is a really nice darkish copper blond natural looking colour. People are not sure if it is my natural hair colour or not

First, let me give a 5 star shout out to Cosmetic World for making this product available to non-professionals. I have been shopping here for over 20 years, it is THE best place in Toronto to get products you won't find elsewhere, and great prices as well.

Eliminates brass!
No need for toner!
Hair stays soft!
Yes it really does get rid of the brass without needing toner, which is a game changer for me.
I use 12-16 with 30 vol developer. Have also tried 12-61 and 12-81 with great results as well.
This LOREAL majirel line has so many lovely shades of blonde . I found this really nice especially for summer as I want to go lighter and brighter . Very pretty - will be buying again !
I love this shade! I used it on my natural black hair to touch up my roots and gave me a gorgeous light brown/golden finish. My original shade was out of stock so I settled for this. I’m so glad I did because this is my be go to shade for summer!
This is a really solid crème developer from Loreal for their Majirel hair dye line. I love the thick consistency and it does take a bit more time to blend and mix however I find this is really good quality. I will definitely repurchase!

What’s the Difference Between Hair Colors?
The main difference between hair dyes is how long they last. Here’s a quick guide:Permanent Hair Color
Permanent hair dye lasts until your hair grows out or is cut. It changes the structure of your hair to create a lasting color that won’t wash out or fade. While it doesn’t require maintenance for fading, you’ll need to reapply it for regrowth or if you want to change your color.Demi-Permanent Hair Color
Demi-permanent dye lasts about 24 washes. It’s ammonia-free and gentler on your hair, making it a great choice for enhancing your natural color or covering gray. It contains a small amount of peroxide, making it more durable than semi-permanent dye and perfect for a variety of shades, from dark to light.Semi-Permanent Hair Color
Semi-permanent dye lasts up to 12 washes before fading back to your natural color. It’s the least damaging option and is ideal for enhancing your natural shade or temporarily covering gray.Why Buy Hair Dye from Cosmetic World?
