We can say that 30 vol developer will not bring about serious damages to your hair under the following factors including, but not limited to

Of all the classic science experiments out there, learning how to make elephant toothpaste has been one of the most amazing I have ever tried. EVER. It definitely has a big wow factor that impresses both kids and adults and leaves everyone talking excitedly about how cool science is! If you have the same desire as the girl in the picture above, then 20 vol is for you. By this, we mean you do not want to lighten the color too much and all you want is just two or three tones. Moreover, 6% peroxide developer works well in light brown hair. Here’s an alternative approach: When performing a strand test, mix your bleach as you normally would and apply it, but only to a few strands of your hair that you’ve removed from your head.How about toning hair? As we have mentioned, 20 volume developer is mainly in charge of lifting hair color; hence, it can’t be used to tone dark hair. It is the best to tone light colors like platinum and pale blonde. For instance, your base is in a light ash blonde extra light golden blonde or platinum blonde, then a silver-grey, golden or purple toner is highly recommended. Another factor to consider is your target color. If you are hoping to lighten your hair by a significant amount, then you will leave the bleach in for a longer period of time. If you are only hoping to go lighter by a shade or two, then you will only need a few minutes. You can literally do everything by yourself if you do it with care and it is not an exception with 20 vol developer. Let’s get started with mixing the color and conditioner at the ratio 1:3 and as we said, try to make it right and just enough to saturate your hair. But not all developers have equal cuticle- and color-lifting power. The weakest developer, 10 volume, is only used to deposit color and won’t lift because it contains only 3% peroxide. You shouldn’t leave 20 volume developer in your hair for more than 30 minutes. However, 30 minutes is a long time.

And the developer volume you choose has a lot to do with how long your hair will take to process and finish lifting. Developer’s role in the bleaching process is an important one. The bottles can easily tip! Once the hydrogen peroxide has been poured into the bottles please have kids hold the bottle steady so it does not fall over and spill. Foam Safety The foam is HOT! Once cooled it is safe to touch however I do recommend keeping your gloves on. Any hydrogen peroxide that may not have reacted with the yeast or might have leaked on the tray or bottle can sting and/or burn the skin.You leave it in the hair for more than 30 minutes. This runs the risk of inactive color and irritating scalp. The place of this volume developer is also crucial. To be more specific, you should leave it 1 inch off the scalp to avoid the itchy scalp. A strand test is when you apply hair dye or bleach to a few strands of hair to see how it will react. cup (4 oz) Hydrogen Peroxide- Use 20 volume for classroom experiment and 40 volume for adult demo.
