Especially for bleach hair, you'll have to grow new hair to get your bleached hair back to usual. The time it would take depends mostly on how rapidly your hair grows, but it might take anywhere from two to three years.
In summary, while some improvements can be seen in weeks, full recovery for severely bleached and damaged hair may take several months to a year, depending on individual circumstances and care practices.
Bleached roots will not go back to normal color. They will grow out and you will have new roots but the bleached roots will remain bleached until you color them to match your natural color. The tricky part with this is that you can not just slap color on the bleached area and expect it to match again unfortunately.
How long does bleached hair last? In comparison to other dyes, hair bleaching is a permanent process which cannot be washed away over time. This is because the melanin, which gives your hair its colour, is stripped away from the hair during the bleaching process.
The good news is that there are solutions for damaged hair. There are no 'long-term' effects from bleaching hair, however, immediately after first bleaching the hair, it becomes prone to damage.
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.
If your lousy bleach job has come out more yellow, you'll need a purple toner. Purple shampoo can help neutralize the yellow. If your hair is orange, you'll need a blue toner. Try a blue shampoo to tone the brassiness and get rid of the orange.
Damage from bleaching is not only permanent; it also continues to build up over time. This is because weakened hair strands will not be able to combat new damage with each successive bleaching session.
Open cuticles make your hair much more prone to breakage, split ends, and frizziness. While you can't undo all the damage bleach does, the fix here is to supply your hair with some added strength to prevent any additional breakage and achieve smoother strands.
Once you have processed or color-treated hair, it can never go back to being virgin. That's right, once you've dyed your hair, even just once, you lose your virgin strands forever. Virgin hair is a hair colorist's dream because it's also much easier to color hair that doesn't already have dye on it.
Getting your hair back to its natural shade depends on the current state of your hair as well as its health. Oftentimes, returning to your natural color takes several sessions with a colorist unless you're planning to let your hair grow out.
However, in this transformation process, bleach can sometimes remove more than just color. Essential proteins, oils and lipids that maintain your hair's strength, moisture resistance, and shine can get stripped away. This can leave your hair dry, fragile and vulnerable to breakage.
When people bleach their hair, there is the time it goes on the scalp and penetrates underneath into the hair follicles, which will harm the skin barrier (acid mantle) and the microbiome and cause irritation and inflammation. This temporary type of hair loss is called telogen effluvium.
If you take care of bleached hair it can be healthy, silky and shiny.
Dyeing and bleaching fine and thin hair
Hair dyeing and bleaching can weaken or damage hair, making it break off faster. Of course, dyeing and bleaching remains a chemical process. Therefore, use a professional product that minimises damage to your hair.
Your stylist's colour-correction methods may vary, but it's likely they'll reapply bleach to lighten your hair to fully remove the orange, then tone your hair with an ash or light beige colour to neutralise brassiness.
Deep conditioning is one of the best ways to repair bleach damaged hair. Deep conditioners penetrate the hair shaft and help to restore moisture and nutrients. Look for deep conditioners that are specifically designed for damaged hair.
Tip 5: Know When You Bleach Your Hair
This is one of the most important hair care tips because hair that is brittle, dry or breaking, should not be bleached.
Avoid washing your hair for the first 48-72 hours after bleaching it. Give your hair ample time to seal in its new color. Because bleaching is such a volatile process, your cuticles remain open for longer immediately following a bleaching session.
While some hair types may hold better the second or third day of washing, in most cases it's best to visit the salon with clean, dry hair. Despite what you may have heard before proms and formal dances back in the day, it's actually preferable to work with hair that is free of oil and buildup.
Applying bleach to dry hair lets the lightening agent penetrate further into your hair cuticle and cortex to dissolve melanin, leading to a more vibrant and bold result.
