Developer contains hydrogen peroxide, which is a pretty aggressive chemical. When used correctly, it helps to open up the hair cuticle and allow the dye to penetrate. But, when used alone, it's like pouring gasoline on a fire - it'll cause chaos and destruction!
What Is Developer For Hair? - Ivirgo Company
The hydrogen peroxide will start to break down the keratin bonds in your hair, leading to a loss of protein and structural damage. It's like your hair is saying, "Hey, what's going on here? I'm being attacked by a chemical bomb!"
Now, I know some of you might be thinking, "But I've heard of people using developer to lighten their hair". And, yes, that's true - some people do use developer as a lightener. But, it's essential to use it with a color deposit and follow the instructions carefully to avoid over-processing and damage!
In conclusion, just putting developer in your hair is not a good idea - it's like playing with fire (or in this case, chemicals)! So, if you want to achieve a new hair color or lighten your locks, always use developer with a hair dye and follow the instructions to the letter. Your hair will thank you, and so will your sanity!
