When it comes to hair, the question of how long should you leave bleach in your hair can be a little tricky. The answer depends on what type of hair you have and how light or dark you want those strands to turn out. However, if there’s one thing that most hairdressers will say is important: don’t overdo it!

Bleaching your hair is a great way to lighten and brighten up those strands, but it can be hard to know how long you should leave bleach in your hair for.

The thing about bleaching your hair is that if you don’t get the timing right then you could end up with some pretty awful results.

Over-bleached locks are not only dry and damaged looking, they’re also incredibly hard to reverse! That’s why we’ve put together this guide on how long you should leave bleach in your hair based on what sort of result you want to achieve. We hope it helps!

How long should you leave bleach in your hair?

There’s a misconception that bleach will work better the longer you leave it on. Wrong! The maximum amount of time recommended for leaving bleach in your hair is 30 minutes. This is so you don’t damage your hair with long-term use.

Some people think that bleach lasts longer on your hair if you leave it for a few hours, but this is not true. This can lead to serious damage including brittle strands and an orange hue in the end result!

Only thirty minutes of bleaching time should be used at most- anything more than that risks too much improper chemical processing that will ruin all those beautiful locks we’ve worked hard (and paid good money) for!

What happens if you leave bleach on too long?

While bleaching your hair can be really fun, it can also go very wrong if you’re not careful. You could end up with a colour that isn’t what you wanted or even worse, damage your locks in the process.

This means leaving bleach in for too long – which can make your hair brittle and break easily – as well as not leaving enough time between treatments (which makes the colour uneven).
