When you bleach your hair, you’ll likely end up with very pale hair or hair with a yellow hue. If that is what you want, great. But if your goal is a clean ash blonde, you may wonder if you can apply ash blonde over bleached hair.
Quick Answer
Yes, you can use ash blonde dye over bleached hair. It is the most effective way to neutralize yellow tones and achieve a cool, matte finish.
- The Dye Type: You can use both permanent or demi-permanent ash blonde dye. Demi-permanent is safer and fades better on bleached hair.
- The Safety Rule: If you buy a box dye, do not use the developer included in the box (usually 20 or 30 vol). Mix the dye with a 10-volume developer to prevent chemical burns.
- The Result: Ash dye has blue/green pigments. If your hair is very porous, do a strand test first to ensure it doesn’t turn your hair green.
Putting ash blonde dye over bleached hair can refresh your look without re-bleaching. You can use ash blonde hair dye or toner over your bleached hair, but the result depends on your starting level and your formula.
Ash blonde shades exist across many levels, from darker ash blonde to very light ash blonde. The key is simple. Your bleached level should match the level on the color you choose.
How to Put Ash Blonde Over Bleached Hair
If you want that ash blonde hair color, this is how to do it at home with better control. Work slowly. Section well. Check your tone as you go.
Safety Notes
- Do a patch test 24 hours before you dye. This checks for allergy.
- Do a strand test first. This checks for green, gray, or muddy results.
- For previously bleached hair, use 10 volume developer only, or choose a demi permanent formula.
- Do not use 30 or 40 volume developer on hair that is already bleached.
- If you use a box kit, do not use the included developer if it is 20 volume or higher. Use 10 volume instead.
- Stop if your scalp burns or stings. Rinse right away. If redness or pain continues, get medical help.
- Do not dye over broken skin or an irritated scalp.
Assess The State of Your Hair
Before you begin, check two things. Your lightness level and your hair condition. Your lightness level should match the ash blonde level you want.
If your hair is not light enough for your target, the ash may look muddy instead of clean. If your hair is light enough, you can focus on tone and shine.
Choose Your Ash Blonde Shade
Ash blonde comes in several shades and levels. Choose based on your preference, your skin tone, and your current bleach level.
Some ash blondes read like cool beige. Others read more smoky and can look gray on very porous hair. Ash shades are meant to reduce warmth, not add warmth.
My Advice
- Semi-Permanent (Gloss/Masks): The safest option. Use these (like purple masks) to maintain ash tone in the shower. They last 1-4 washes and cause zero damage.
- Demi-Permanent: The best choice for dyeing bleached hair. It uses low developer (deposits only) and lasts 20+ washes without frying your hair.
- Permanent Color: Avoid this on bleached hair if possible. It contains high ammonia/peroxide and causes unnecessary damage for a color that is only being deposited.
- Toner: This is technically a sheer demi-permanent dye designed specifically to neutralize yellow/orange.
Prepare the Ash Blonde Hair Dye
After you pick your shade, prepare your dye or toner. If you have longer or thicker hair, plan for extra product so you do not run out mid-application.
Mix the formula exactly as directed. Use gloves and a dye brush so you can apply evenly from root to end.
Apply
Divide your hair into manageable sections. Apply the ash blonde toner or dye evenly. Saturate from roots to ends. Take your time so you do not miss spots.
Leave the Product on Your Hair
Leave the product on for the time listed on the label. Check a small section every few minutes, especially if you are using toner.
Timing Notes
- Do not go past the maximum time on the label.
- If your strand test processed fast, expect the full head to process fast too.
- If the tone turns too smoky or dull, rinse sooner.
Rinse Your Hair
Rinse when the time is up. Cool water is a good choice because it is gentler than hot water.
Rinse until the water runs clear. This helps remove leftover pigment before you shampoo and condition.
Wash and Condition Your Ash Blonde Hair
Once the water runs clear, shampoo your hair. Work it into a rich lather. Then condition.
A deep conditioner is best after bleach and color. It helps restore softness and hydration. If you only have a regular conditioner, that can still help.
Style Your Hair
Style your hair once it is dry. This is when you will see the true tone and shine.
Heat Notes
- Pat dry with a microfiber towel. Do not rub.
- Air dry when you can.
- If you must blow dry, use cool or low heat only.
Pros and Cons of Using Ash Blonde Over Bleached Hair
Here are the main benefits of putting ash blonde over bleached hair at home.
- It is a flattering tone on many skin tones.
- It can reduce the yellow hue of bleached hair.
- It can soften the look of slight unevenness from bleaching.
Here are the main drawbacks.
- If the bleach level is uneven, the ash result can look patchy.
- Very porous hair can grab cool pigment and look green, gray, or dull.
Troubleshooting
| If you see this | Try this |
|---|---|
| Green or swampy tone | Your hair may be very porous or your base may be too warm. Use a porosity equalizer or protein filler next time. For now, wash once with a clarifying shampoo, then use a beige or warm gloss to soften the green. |
| Too gray or dull | Rinse sooner next time and use a beige toner instead of a very cool ash. Add moisture masks to reduce rough porosity. |
| Still looks yellow | Use a violet based toner or purple shampoo. Yellow needs violet. Orange needs blue. |
| Patchy result | Section smaller. Apply to damp hair for more even absorption. Use a porosity equalizer to reduce uneven grab. |
| Hair feels stretchy when wet | Stop chemical services. Focus on bond and protein care. Consider a professional color correction plan. |
Ash blonde can look clean and modern when the level and tone match your base. Use a strand test to confirm the result before you commit to the full head.
