How to Bleach Hair at Home DIY Hair Bleaching Tips From Colorists

how long to leave bleach on hair

Stages 3 and 4 can be confusing because light brown can look like dark blonde. Knowing your starting and ending point will help you understand how many levels your hair needs to go through. Then just pour over the hair and rub in very vigorously, so the entire head gets into contact with the toner. Use the violet blonde toner if the hair is more on the yellow side. If the hair is darker than that at this stage (as in the picture above), you need to make a fresh mix and apply again. If the hair is still at 9 or so, and it's been 15 minutes you need to keep processing it.

Leaving Bleach in Hair for Too Little Time

I’ve got a whole post devoted to how long you have to leave coconut oil in your hair before bleaching. You want to make sure you have everything there ready to go. If not, you’ll wind up having to run to the store or even worse, wing it, because you forgot something. I recommend just a few ends on the underside of your head because if you hate it, you can snip those off, and no one will ever see it. But if you love it, then you will be ready to go for the whole bleaching session. So, you’re probably asking yourself, how long do you leave bleach in your hair?

It is possible that you won’t need to undergo the full process of bleaching during the second attempt. If you’re using a hair color kit, you can easily follow the instructions on the box, including details on how long to leave the bleach on.

The bleach won’t lighten to the degree it’s supposed to, so you might have a color that’s not much lighter than how you started. Bleach is an aggressive substance that contains ammonia and hydrogen peroxide. These chemicals can burn your scalp if it has extended contact. If you feel your scalp start to burn while you’re bleaching your hair, wash it off immediately. So, you’ve decided to switch up your look and go full-fledged blonde, now what?

However, it’s always best to consult with a professional before bleach your hair at home. They will be able to give you specific instructions on how long to leave the bleach in, as well as what type of bleach to use. If you’re working on dark hair, Asian hair, or hair dyed black, use a blue-based bleach to tone down the orange pigments.

Apply bleach to a few hidden strands from the underneath layer of your hair and time how long it takes to lighten. If you need to lift your color more than 2 levels, you’ll have to use 30 volume or 40 volume developer (not recommended for at-home use). It’s easier to understand how long you can leave bleach in your hair when you know what developer is doing in the mix in the first place. You mix developer with bleach to either deposit or lift hair color. If you leave bleach on your hair too long, you will permanently damage your locks and can even lose hair in the process. If you don’t leave it on long enough, you won’t achieve the lift you want and may get uneven, patchy results.

Dos and Don’ts of Using Splat to Bleach Hair

Keep checking your hair every 2-3 minutes to see the shade it’s turning into until you get the shade you want. Keep a note of how long you’ve had the bleach in your hair as well – this will be the time that you’ll use it when you bleach the rest of your hair. Well, simply put, a strand test is when you apply the bleach on a few strands of your hair and carefully keep an eye on the time until you get the results you want. Basically, what you need to do is to prepare a small amount of bleach, and then dab it on a couple of hair strands. Choose the ends because you can always cut them out if you don’t like them. Similar to the toner, a purple shampoo helps eliminate orange or yellow hues in your hair.

Adding excessive amounts of bleach to your hair can lead to something called over-processing, which is when your hair shaft becomes brittle and damaged. Over-processing can also cause breakage and hair loss which is the last thing you want to deal with, so make sure that you’re treating your hair with care. Last but not least, the type of developer (hydrogen peroxide that aids in the bleaching process) you use can influence how long bleach should remain on your hair. Developer is available in different volumes; lower volumes typically require a longer time to work their magic, and vice versa for higher volumes.

Writing for respected publications like Forbes and HuffPost, she’s committed to bringing her passion for great hair to the masses. Rather, you what you should do is bleach first the level 6 root area and let the mix sit there for 10 minutes or so. Make sure that you saturate the hair properly with the product mixture. Work fast so that that you can give the whole head an equal amount of processing time.

After 30 to 45 minutes of exposure to the hair, the bleach starts to eat at the hair’s keratin, making the strands weaker and brittle. There have been speculations that the bleach mixture will only work for a certain period then it goes dormant. This is true to some extent meaning the bleach will only lift the hair about two to three shades, where a higher developer volume will lift more. However, other factors such as your hair type affect how much your hair can be lifted. From 20 to 40 minutes, it can lift the hair two to three tones lighter.

That will also result in greater damage, so it’s wise to be realistic about the shade you want to go. This becomes tricky when you have different levels of hair color at the same time, which is common for color-treated hair. Hair may be lightest at the ends and darker at the roots, so it needs to be lightened differently.

If you have coarse or very dark hair, you can leave it a few minutes longer. But make sure you keep checking it’s effect so you can rinse it out as soon as it’s achieved the colour you want, before it causes too much damage. It’s quick, easy, and relatively affordable– all the makings of a great beauty hack! But don’t let anyone fool ya; bleaching your hair can be a damaging process at times. One golden rule that hairdressers universally agree on is to avoid overdoing it. When you get your hair bleached at a salon, they’ll be checking in on your hair to make sure that it’s processing well.

There are so many different hairstyles to choose from, but bleaching gives you a unique look. If you feel ready to bleach your hair, make sure you follow the tips and timelines above to get the perfect shade for your hair. Hairdryers, straighteners, and curling irons dry your hair out already, so using them on bleached hair can cause breakage. When you’re bleaching at home, you might get nervous about how long to leave in the bleach. If you wash it out too soon, the chemicals won’t have a chance to make a difference in hair color.

We really recommend doing a strand test before using bleach because there are so many variables at play when bleaching your hair or someone else’s. 10 volume bleach can be safely left in your hair for up to 30 minutes before the chemicals stop working and the hair starts being over-processed. The ideal timing can vary depending on your hair’s unique characteristics and the strength of the bleach you’re using. The harsh chemicals used in hair bleach kits have been known to cause split ends, dryness and breakage. Studies published in the Journal of the Society of Cosmetic Chemists have shown how bleach interacts differently with various hair types.

Bleaching also works in removing artificial hair color, for example, if you want to remove previous hair dye and you want to start over. This is a required step to prepare the hair for coloring, usually for lighter shades. You might not achieve your desired results on the first try so it’s important to be patient.
