If you’ve ever experienced a hair color mishap, you may have wondered about the possibility of bleaching your hair twice with 20 Volume Developer.
It seems easy to try when you want to lighten your hair color quickly, but it’s important to understand the potential risks and consequences.
In this article, we’ll discuss the potential risks of bleaching hair twice with a 20-vol developer & how long to wait before bleaching again.
Is It Okay To Bleach Hair Twice?
Stylists don’t recommend bleaching hair twice in the same session. The bleaching process damages the hair, especially when done multiple times in a short period.
Bleaching hair twice in one session damages the shaft, leading to breakage and split ends. Bleach opens the hair cuticle, making it more vulnerable to damage. When you over-bleach your hair, you lose the natural moisture and end up with dry and brittle hair.
Wait a few weeks between bleaching sessions to allow your hair time to recover. While you wait, you can take care of your hair with heat-protectant sprays and deep conditioners to prevent further damage.
Can You Bleach Hair Twice With a 20-Volume Developer?
No, professionals advise against bleaching your hair twice with a 20-volume developer. The high volume is harsh on hair and causes dryness, breakage, and brittleness. It will lighten your hair up to nine levels to give your hair time to adjust before trying again.
The volume of hydrogen peroxide contained in the product impacts the developer’s strength. A 20-volume developer contains 6% hydrogen peroxide, making it very strong.
Using this harsh chemical too many times causes excessive damage to your hair. If you need to lighten your hair further, use a low-volume developer instead.
How Long Should You Wait Before Bleaching Hair Again With a 20-Volume Developer?
Wait a week or two before bleaching your hair again with a 20-volume developer. This period gives your hair time to recover. You should use a nourishing treatment before and after bleaching to help repair your hair.
Can You Bleach Hair Twice With Developer in One Day?
No, stylists never recommend you bleach your hair twice in one day with a developer. Putting your hair through such involved treatments without an adjustment period causes extensive damage.
There’s no rush to lighten your hair and risk ruining it, so give yourself time after using the 20-volume developer. See how the color looks after you shampoo and nourish your hair.
If you need to lighten your hair more than one shade, wait several days between bleaching sessions and try using a lower volume developer.
Things To Consider When You Bleach Hair Twice With 20 Volume Developer
You shouldn’t attempt to bleach your hair twice with a 20-volume developer because it’s so strong. However, if you’re determined, consider the following concerns and make sure you protect your hair and skin from the harsh bleach.
i) Assess Your Hair Before Bleaching
Use a 20-volume developer only if your hair is strong enough to handle it. People with weak, damaged, or overprocessed hair should avoid using a 20-volume developer since it’s so harsh. Even if you think your hair can take it, try doing a test strand.
ii) Prep Your Hair
Prep your hair before you start the bleaching process. You’ll provide the necessary moisture and nourishment to keep your hair healthy after applying the 20-volume developer.
- Make sure you use a deep-conditioning treatment after bleaching your hair twice with a 20-volume developer.
- Use a clarifying shampoo before bleaching your hair to remove any product build-up.
- Use a heat protectant spray before applying the 20-volume developer to prevent damage.
iii) After Using 20 Volume Developers the Second Time
Once you’ve dyed your hair twice with 20 volume developer, waiting at least a week between processes ensures you’re taking the best care of your hair. Switch to a color-safe shampoo and conditioner to nourish your hair. Add a leave-in conditioner for extra moisture.
Avoid styling your hair with hot tools and exposing your hair to direct sunlight for at least a few days after bleaching. The sun’s UV rays can lighten your hair even more, causing a color you didn’t intend to have.
So, Should You Bleach Hair Twice With a 20-Volume Developer?
No, you shouldn’t bleach your hair twice in one day with a 20-volume developer. If you bleach your hair and want to lighten it further, wait at least a week before trying again.
Consult a professional stylist before bleaching your hair to ensure that you use the right products and techniques for your specific hair type and have realistic expectations of what your hair can handle.
