Can I Tone My Hair Twice After Bleaching?
It’s a common myth that you can’t tone your hair more than once. But actually, there are two cases in which you should be able to get the toner effect twice.
The first is if you’re bleaching your hair and applying toner afterwards – this is technically the same process as having it done at a salon and will achieve the same effect.
You should also be able to do it again two weeks after, at least for some types of toners (say, red).
The second is if you’re dyeing your hair with a toner, which is designed to deposit dye rather than bleach.
This means it doesn’t actually alter the structure of your hair at all, but simply deposits colour onto it.
If you’re doing this more than two weeks after your first application of this kind of toner, you shouldn’t get the same results, but it shouldn’t be damaging in itself.
A word of caution with both these methods, though: if you’re using a pre-shampoo toner, make sure it doesn’t contain any ammonia.
If it does, the ammonia will sit on your hair and turn into chlorine dioxide (the chemical used in most permanent hair dyes) when you shampoo.
This is extremely damaging, and will strip your hair of all the dye you’ve just applied.
So, if you’re going to apply a toner more than once, you need to be really careful to avoid any products with ammonia in it.
If the toner has any obvious ammonia-based ingredients, avoid it – they’re not worth the risk.
Alternatively, start using pre-shampoo toners, which are applied after shampoo but before dyeing.
With these you can also use the same colour more than once – just make sure you don’t leave it on for longer than 15 minutes on each application.
What does this Mean for you?
Well, if you want to try a toner more than once, don’t do it. If you’re using a pre-shampoo type of toner, it’s probably best to use a conditioner or leave-in conditioner after it as well – that way the ammonia from the toner will be neutralised.
You could also try to find a post-shampoo toner that doesn’t contain ammonia.
A Final Word of Warning
Always make sure you don’t leave any conditioner in your hair, and if you do, make sure it’s rinsed out well. There’s a very real risk of skin irritation from hair dye which can be exacerbated by the oils in conditioners.
