Whether you have box-dyed your hair or dyed it professionally, it is recommended not to deep condition or wash your hair for up to 72 hours after the process.
Why? You risk fading the color, as deep conditioning will strip color from your hair, and you’ll lose your desired look.
Not only have you wasted money, but you also risk damaging your hair further. So, how would using a deep conditioner immediately after dyeing your hair damage it further?
- Condition right after you rinse out dye to smooth the cuticle and reduce tangles.
- Wait 48 to 72 hours before your first shampoo to help slow early fading.
- Use lukewarm water. Hot water can speed up fading.
- Deep conditioning is fine. Choose a color-safe mask and avoid “clarifying” treatments right after coloring.
Why You Should Wait 72 Hours to Shampoo (But Conditioning Is Fine)
After a coloring process, your hair may seem more frizzy, dry, and brittle, even if it was healthy and vibrant before coloring. Using conditioner right after you rinse out the dye helps smooth the cuticle and adds slip, which can reduce tangling and breakage.
So, is this a bad thing? No. Conditioner does not “push out” dye. What fades color fastest is shampoo, hot water, and frequent washing.
Hair dye is usually an alkaline process, which can raise the cuticle during coloring. A conditioner is often more acidic, which helps bring hair closer to its normal pH and smooth the cuticle again. That is why many dye kits include a conditioner to use right after rinsing.
- Always follow the dye kit or your stylist’s instructions, including the patch test. Stop and rinse right away if you feel burning, intense itching, or swelling.
- Get urgent medical help if you have trouble breathing, facial swelling, or widespread hives.
- For ingredient and safety basics, see the FDA: hair dyes.
- This is general information. It is not medical advice.
Is It Okay To Deep Condition Before I Dye My Hair?
Just thinking about dyeing your hair can feel damaging (hypothetically speaking). If your hair is dry or already damaged, deep conditioning a few days before coloring can help it feel softer.
You’ll want to give the deep conditioning treatment enough time to support moisture and help your hair feel smoother.
However, avoid heavy product buildup right before coloring. Some very oily or silicone-rich masks can reduce color penetration and lead to uneven results. A good rule is to deep condition 3 to 4 days before dyeing, then keep hair clean and product-light on dye day.
Does Your Hair Even Need Deep Conditioning?
Most color-treated hair benefits from deep conditioning about once a week. You likely need deep conditioning if:
- Your hair feels rough or tangles easily, especially when wet.
- The ends look dry or split, or you see breakage when brushing.
- It looks dull even after regular conditioner.
Things To Consider After Dyeing Your Hair
There’s nothing worse than spending a bunch of money on getting the ‘perfect’ look of your hair, and then a couple of weeks later, it looks dull, damaged, frayed, and lifeless.
So, how do you keep your hair looking its best after dyeing it?
Wait To Wash Your Hair
After you dye your hair, the formula raises the cuticle so color can enter the hair fiber. After you rinse, conditioning helps smooth the cuticle again.
If you shampoo your hair the same day or the next day, you can remove some dye at the surface and speed up fading within the first week.
It’s recommended to wait 48 hours, or up to 72 hours, before your first shampoo if you want the color to last longer.
Rinse With Cold Water
When you do hop in the shower after 48 hours, use lukewarm water. Hot water can speed up fading.
Cold water or cool water at the end of your rinse can help keep the cuticle smoother, which may slow fading over time.
Avoid Swimming Pools With Chlorine
Pool chlorine and other oxidizers can fade hair color quickly. Some pools also contain copper, which can shift light hair toward a green tone.
Chlorine can strip your freshly dyed hair and may also change its color.
What Do I Use When It’s Time to Deep Condition My Hair?
When you go to deep condition your hair, look for conditioners made for color-treated hair. Ingredients like argan oil, almond oil, coconut oil, rosehip oil, or aloe vera can help with softness and shine.
It’s a good idea to use the conditioner that comes with your dye kit immediately after dyeing your hair to lock in moisture and reduce that rough, dry feeling. For deep conditioning, many people wait until the first shampoo day (48 to 72 hours later), but a color-safe mask is also fine earlier if you do not shampoo.
Bottom Line
Deep conditioner does not automatically strip fresh hair dye. The bigger causes of early fading are shampoo, hot water, frequent washing, and chlorine. Condition right after coloring, then wait 48 to 72 hours to shampoo if you want your color to last.
