Can You Mix Purple Shampoo With Developer? – Expert’s Tips And Advice

Can you mix purple shampoo with developer? If you come up with the idea of combining the two products for whatever purposes, we’re glad you ask before pulling the trigger!

There is a lot of creativity around matching and mixing hair care and coloring products, especially when it comes to dyeing and bleaching. 

While there are certain successes when people think outside the box, such as the case of bleach powder, regular shampoo, and developer to create an effective home-use bleach bath, futile efforts or even hair disasters are equally commonplace. 

Can you mix purple shampoo with developer? Today, we’ll examine the potential outcomes of mixing purple shampoo and developer to determine if they are a match made in heaven or a troublesome duo!

Unfortunately, the answer is No. You should not mix purple shampoo with developer as doing so makes no sense and you won’t reap any benefits.

Yet, first, we want to clarify your intention when you want to combine these two products. 

Are you expecting the purple shampoo to work the same way as a permanent dye and turn your hair purple when it is activated by the developer? Or else, are you planning to do a bleach bath but want to make a twist by replacing the regular shampoo with a purple one?

Whether you fall into which situation, the answer to this question is the same – they JUST won’t work!

The purple shampoo is not meant for hair color changing, and including purple shampoo in a bleach bath will serve no purpose! 

This mixture of purple shampoo and developer also does not darken or tone your hair or bring any positive change to your hair at all. The only thing that this good-for-nothing duo can do is to cause further damage to your hair strands. 

Why Purple Shampoo And Developer Won’t Dye Your Hair? 

If you plan to dye your hair using a mixture of purple shampoo and developer, it would be a disappointment to see the results. 

Purple shampoo can’t change the color of the hair strands, or to be more exact, can’t turn your hair purple. It is not formulated to function as a hair dye, after all. 

Instead, purple shampoos are meant to neutralize the style-ruining brassy, yellow tones that usually show up on freshly bleached hair. These pigment shampoos are also used to keep blonde hair vibrant, fresh and ashy after coloring. 

The purple pigments are temporary dye molecules that wrap around the hair’s surface to tone down brassiness. These pigments don’t have ammonia in them, and thus, they only offer a temporary fix for brassy tones. 

But what exactly is ammonia? It is an alkaline chemical that is mainly responsible for elevating the pH level of the hair strands. Normally, our hair’s pH level sits on the acidic side of the spectrum, at around 4 to 5.5. 

Ammonia makes the hair more alkaline and opens up the cuticles for the color pigments to access deeper into the hair. For this reason, this agent is commonly found in permanent dye. 

Due to the lack of ammonia, purple pigments in these shampoos cannot open up the cuticles to penetrate the hair fibers, and the color won’t hang on. 

Instead, the only thing that the pigments in purple shampoo do is coat the color on the exterior of the hair shafts without opening up cuticles to allow the purple pigments to penetrate into the hair. 

This coat will be gradually washed away every time the hair comes into contact with water.   

We have to repeat ourselves that these pigments only create a temporary mask that is not made to change the color but hide tones. 

When you lather the shampoo with water, the hair strands become more porous and absorb the violet pigments to correct the brassy, yellow undertones in hair. 

Besides, even when there is ammonia in the formulation of purple shampoo, the outcome cannot be the same as you would with a permanent dye. 

In summary, if you want to dye your hair purple, you’d better abandon the idea of using purple shampoo, but should buy yourself a temporary, semi-permanent, or permanent purple dye, depending on your personal preferences.

So, What Happens If You Mix Purple Shampoo With A Developer For A Bleach Bath? 

The mixture you’re going to use can only cleanse and lighten your hair. Peroxide in the developer is made to remove the color pigments. 

When you use the purple shampoo for whatever purposes you have in mind (toning the bleached hair or fighting the brassiness), remember that the moment the purple shampoo interacts with the developer, the peroxide will “eat” all the color pigments, including the violet pigments. 

This means that the amount of purple shampoo will go to waste. 

Therefore, if you want to tone your freshly bleached hair using purple shampoo, wait until the bleach bath is over. 

Otherwise, if you plan to lighten your hair in a gentle and gradual fashion or only wish to lift one level at a time, we recommend combining a developer with a colorless shampoo.

How To Lighten Your Hair With A Developer? 

It is possible to lighten your hair at home by a few shades by doing a bleach bath. This technique involves soaking your hair in a diluted bleach mixture (with the developer and regular shampoo) to lift the hair color gradually. 

Compared with regular bleach, a bleaching bath is more gentle as it uses the diluted strength of the bleach. For those with sensitive scalp or who often suffer from conditions like atopic dermatitis, a bleach bath is a safer option!

Essential Items

  • Bleach powder
  • Developer (10 or 20 volumes)
  • Gentle shampoo (not colored)
  • Coconut oil
  • A small bowl
  • Hair clips
  • Shower cap
  • Wide-tooth brush

Step-By-Step Instructions

Step 1: Mix The Bleach Powder And The Developer

As mentioned, developers have different levels, which shows how much peroxide they contain. It depends on how much you want to lift the hair color to choose the right developer. 

  • 10-volume developers can lift 1-2 shades when used in conjunction with bleach. You should use this concentration on fine or compromised hair to avoid damage.
  • 20-volume developers can lift 3-4 shades. This is a great option for those with healthy hair who are after a more significant change in the hair color. 
  • 30-volume developers are so powerful when combined with bleach, and you should not use them for a bleach bath. 

If this is your very first bleach bath, we recommend going for a 10-volume developer to see how much lifting it can do for your hair.  

Start by mixing bleach powder and developer in a bowl, with a 1-2 ratio (1 part of bleach with 2 parts of developer).  The ideal amount of the product should be anywhere between 25 and 50ml, depending on your hair length and thickness. 

Part hair into 4-5 even sections for better-controlling application afterwards. Put on a pair of gloves to get ready for the lightening job. 

Step 2: Add Your Chosen Shampoo

Any everyday colorless shampoo will do the job, but we recommend choosing a highly moisturizing shampoo that contains essential nutrients like keratin, argan oils, and/or essential oils. 

The bleaching process is incredibly aggressive; your hair will feel dry and weak right after. The moisturizing agents in the shampoo help combat dryness, whereas the nutrients work to restore your hair’s health.

Pour the gentle shampoo into the bowl – you need to add the same amount that you would normally use to shampoo your hair. Then, add some drops of coconut oil before stirring the mixture so they can blend before applying.  

Step 3: Apply The Bleaching Mixture

Wet your hair as normal, and then towel dry it – you need slightly damp hair for the mixture to work at its best. Use a brush to apply the mixture. Start with the ends and work all the way up to the roots. 

Remember that the roots should be the last section where you apply the bleaching mix. Hair at the roots always bleaches quicker than any elsewhere due to the heat emanating from the scalp. After that, get back to cover the hair close to the roots. 

Gently comb your hair with a wide-toothed brush before clipping it up and covering your head with a shower cap. 

Step 4: Wait For The Chemicals To Develop

Let your hair sit until it shows the desired shade. Usually, the developing time should range from 10 to 30 minutes, depending on the existing hair color, hair texture, and condition. Go back and check how the color changes every 5 minutes. 

  • Light hair: 7-10 minutes
  • Dark hair: 10-15 minutes or more (as long as you’re not exceed 30 minutes)

If you’re brave enough to use a 30 or 40 volume developer, never leave the bleaching mixture on your hair any longer than 7-10 minutes. 

Step 5: Rinse Your Hair

When you achieve the desired color or 45 minutes is over, wash your hair with cold water thoroughly. 

Step 6: Follow With A Deep Condition Mask

Your hair might become very dry after a bleach bath. Thus, you should apply a deep condition mask to counteract with the drying effects of both bleach and purple shampoo. Leave it on the hair for the amount of time specified in the instructions. 

After that, thoroughly rinse your hair with water and let it air dry to allow it to recover. 

Caring Tips For Hair After A Bleach Bath

  • Watch out the frequency

Bleach bath is highly damaging to hair in a sense that it leaves hair drier and more porous. Thus, it should not be used regularly. We only recommend using this lightening method one to two times at max in a year. 

  • Restore moisture

Hair going through a bleach bath requires the same attention as it would with a true bleaching process. Always follow up with a conditioner after you shampoo. 

When your hair is still dry, you may want to give it a leave-in conditioning treatment to further replenish the moisture and lock the moisture in by a smoothing serum afterward. 

After the bleach bath, let your hair recover and rest for at least a week before doing anything else like heat styling.

  • Always use heat protection: 

Avoid styling your newly bleached hair with hot tools unless you really need to do so. When heat styling, make sure to apply a heat spray or serum to protect your weak hair against the heat.

How To Use Purple Shampoo To Tone Your Hair?

Step 1: Wet Your Hair

Wet your hair. Keep in mind that you’ll only need sobbing wet hair. If your hair is too wet, the water will dilute the purple shampoo and reduce its effectiveness.

Step 2: Apply The Purple Shampoo

Apply the shampoo, use your fingers to massage your hair gently and build up the lather. Pay close attention to those areas plagued by unwanted brassy tones while lathering; you need more shampoo on these places to eliminate the brassiness. 

Step 3: Let It Sit

Depending on how severe the brassiness is, let the purple shampoo on your hair for two to three minutes.

Step 4: Apply A Conditioner

Purple shampoo can dry out your hair, and a conditioner is a great remedy. Applying the conditioner not only provides the moisture, but also helps to nourish your hair and minimize potential breakage.

If your hair is extremely brassy, you may want to use purple conditioner on your towel-dried hair. 


Can you mix purple shampoo with developer? The answer is NO! You should not try this if you don’t want to waste your time and money.

Here is our advice! When you want to dye your hair purple, always turn to a quality hair dye. If you wish to tone your hair after bleaching or correct the unwanted brassiness, let’s wait until you finish the bleach bath and use the toning shampoo. 

Simply put, purple shampoo and developer are not meant to be together; not only they can’t function well when blended, but they also cause hair weakening and damage in some cases.
