The risks for scalp damage after washing is that your shampoo has stripped the oils from your scalp that provide a slight barrier (you shouldn't apply bleach directly to the scalp anyways unless you're using a gentle on-scalp bleach) and that any irritation/scraping from the manual process of washing could be inflamed ...
A bleach bath typically lightens hair by about 1-2 levels, but the result can vary based on factors like hair colour and processing time.
Keep in mind that color-wise, the end result will usually be the same whether you're going to the salon with freshly washed or dirty hair. Allowing oil to accumulate before bleaching your strands is solely to nourish your scalp and should have no impact on your desired color.
In conclusion, it is recommended to come to your hair appointment with clean hair but not freshly washed or wet hair. Communication is key, so don't hesitate to ask your stylist for their preference to ensure you get the best possible results.
“Hair should almost always be somewhat clean and dry—meaning no dry shampoo, no styling products, and no excessive oils, although a little natural oil is fine," Perkins says. Remember, bleach is notorious for ruining fabrics—so choose what you wear wisely. “Remove your bathroom rugs to ensure nothing drips.
Do you put bleach bath on wet or dry hair? As its name suggests, a bleach wash for hair is applied to wet strands. This allows the formula to spread faster and more evenly throughout the hair and dilutes the potent formula so that less damage occurs compared to a regular bleach process.
20 Volume (6%): Provides moderate lift and is commonly used for covering grey hair or lightening natural hair colour by one to two shades. 30 Volume (9%): Offers significant lift and is suitable for lightening natural hair colour by two to three shades. It is often used in more substantial colour changes.
Remember, high lift colour is an alternative to bleach. It provides a single-process application to help minimize damage. While high lift colour could be less damaging than bleach, even the gentlest hair colour can cause damage. This is because it raises the cuticle and chemically alters the inside of your strands.
Will Your Hair Fall Out If You Bleach It? Whilst no one can say your hair won't fall out if you bleach it, it's not very likely. Bleached hair will only fall out if it's been overprocessed to the max or the bleach is left on for far too long, which shouldn't happen with a trained professional.
Bleaching wet hair creates a diffused, soft effect, and the resulting color covers a larger surface area. Whereas, bleaching dry hair allows you to achieve more targeted results.
In general, it's recommended to wash your hair a day or two before your dye session rather than immediately before it. Skipping a day allows for oils to build up on your scalp, which, in turn, helps protect against irritation that can be caused by hair dye.
If you're applying bleach to wet hair, keep in mind that the color of your strands won't lift as much as it would if applied to dry hair. This is because the water on your hair will dilute the bleach, resulting in softer results.
If your hair turned yellow after bleaching, you can apply the following on your hair: the red petals of hibiscus, purple shampoo, henna, and apple cider vinegar.
Don't Overprocess
Using too high percent of developer will cause the hair color to lift too fast causing damage to the hair cuticle,” says Faye. Rez adds that leaving the bleach on too long—even with a lower volume processor—can also contribute to damage.
Hair dye volumes refer to the strength of the developer, which impacts the level of color lift. A 10 Volume developer provides minimal lift, perfect for depositing color. A 20 Volume developer lifts hair by 1-2 levels, while a 30 Volume developer lifts by 2-3 levels.
From a strand test, you should also get a better sense of how many sessions you'll need to make the full transition. For example, going from dark brown to light blonde hair may require three to four sessions.
Greasy hair is the recommended hair condition for bleaching, as your hair's natural oils are well-equipped to resist the bleaching process, and protect the scalp from chemical damage. We recommend bleaching hair at least 72 hours post-hair wash for ultimate protection.
How many levels does a bleach bath lift? A bleach bath can lift hair color by one to two levels. This is typically not as significant as the lightening achieved through traditional bleaching.

Tip 1: Prepare your hair
Minimise the use of chemicals and maximise the use of moisturising and protein-boosting treatments a few weeks in advance of bleaching.” Treat your hair with TRESemmé Botanic Moisture & Replenish Oil Mist. It's enriched with coconut oil and aloe vera to boost moisture and replenish hair.
When To Use Purple Shampoo After Bleaching? Avoid washing your mane for the first 48 to 72 hours after bleaching it. This is to give your hair enough time to seal in its new color. If you waited 72 hours before washing your hair after it was bleached, you could use the purple shampoo the next time you shower.
Lightening your hair more than three shades requires higher volumes of peroxide, which causes more hair damage. Editor's Note: Once the bleach starts to dry, it stops processing your hair, and your strands won't get any lighter from that point on.
