Who is it for?

No matter what color you’ve opted for, newly-dyed hair that comes out great always puts you in a good mood. However, colored hair needs proper and extra treatments so the color will last longer. Pretty sure you don’t want to see all that money and time you spent coloring hair wasted, right?

For fully hydrated hair, consider the Hydrasource Shampoo.

The Texture, Smell, Packaging, and More

Biolage ColorLast Shampoo has a bit of a thick, milky white texture (a little goes a long way) and lathers up very well. It doesn’t leave residue behind (which is a good thing especially if you have oily hair and scalp). It easily washes out, too.

The smell of this shampoo is pleasantly floral. While many users love it, some might not stand for the smell. However, the scent doesn’t linger after you finish washing and drying your hair.

If you are someone that prioritizes eco-friendly packaging, you’ll be happy to hear that Biolage ColorLast uses 100% recycled bottles (excluding the caps) to support better landfills. The 400-ml bottle is pretty sleek and perfectly fits in your palm. As for the one-liter bottle, it comes with a pump for easy deposit.

In the next section, we discuss Biolage ColorLast shampoo ingredients to help you determine if this is the right professional shampoo for you.

Biolage ColorLast Shampoo Ingredient Breakdown

We all love paraben-free shampoos, and the Biolage ColorLast Shampoo is exactly that. Biolage prides itself on using 100% vegan, no animal-derived ingredients as well as a pH-balanced formula to preserve your color vibrancy.

Given below are all the ingredients in the Biolage ColorLast Shampoo.

Water, Sodium Laureth Sulfate, Coco-Betaine, Sodium Chloride, Glycol Distearate, Dimethicone, Fragrance, Sodium Benzoate, Hexylene Glycol, Cocamide Mipa, Salicylic Acid, Carbomer, Guar Hydroxypropyltrimonium Chloride, Limonene, Hexyl Cinnamal, Coumarin, Linalool, Butylphenyl Methylpropional, Benzyl Alcohol, Benzophenone-4, Hydroxycitronellal, Amyl Cinnamal, Methyl Cocoate, Orchis Mascula Extract, Sodium Cocoate, Sodium Hydroxide, and Citric Acid.

At first glance, you may think the formula seems odd because there is Sodium Laureth Sulfate (SLES) in it. Many people with color-treated hair stay away from it due to its ability to strip too much of the hair’s natural oil and hair color.

However, to get a better understanding of sulfate and other standout ingredients, below we discuss how they work individually along with the pros and cons.

Sodium Laureth Sulfate (SLES)

We’re pretty sure all of us know the function of sulfate; Create a lather to deeply cleanse your hair from dirt and oil. However, sulfate may strip too much of the natural oil. Sulfate might also strip out hair color, though the scientific reviews are mixed.

Unfortunately, sulfate is often misinterpreted as a culprit behind color fading. In fact, the primary cause of fast color fading is usually the combination of water and hair damage. So, washing your hair with or without sulfate-free shampoo will eventually lead to a faded color.

Here’s the science behind it: During the coloring process, large dye polymers are formed in the hair cortex and get stuck there due to their size. When in contact with water, the hair shaft will swell which forces the cuticles to open as well. This is why the dye molecules leave the cortex, making your hair color fade.

Damaged hair also plays a major role in color fading. Everyday hairstyling activities, sun exposure, and the coloring process itself can lead to damage. When hair gets damaged, the natural lipid layer (18-MEA) cracks, leaving your hair shaft unguarded.

Eventually, water is able to sneak into the hair cortex and washes out the dye molecules. Shampoo may accelerate color fading due to the action of surfactants – not only sulfates but other surfactants also come into play.

Our point is that don’t let sulfate be an obstacle in using Biolage ColorLast Shampoo, but don’t use it often. If sulfate is indeed a big deal for you, then Biolage may not be your go-to color protection shampoo.

Butylphenyl Methylpropional

Biolage ColorLast Shampoo contains 11 fragrance ingredients. But, Butylphenyl Methylpropional is the one that caught our attention due to the controversy around it. It is also known as lilial and p-t-Butyl-alpha-methyl hydro cinnamaldehyde.

As of March 2022, lilial is banned in the EU and Northern Ireland due to its classification as a “carcinogenic” substance by the EU’s European Commission back in 2020. It can pose risks to fertility in animal studies due to its endocrine-disrupting properties.

However, more research is needed to understand the impact on human health due to insufficient data regarding evidence of exposure to lilial.

The EU’s Scientific Committee on Consumer Safety notes “When considering the use of multiple product types used at the same time the proposed concentrations of lilial cannot be considered as safe.” They also note that lilial is considered safe when used as a perfuming ingredient in leave-on or rinse-off products.

Most importantly, the amount of lilial in Biolage ColorLast Shampoo is way much less than the amount that could cause reproductive toxicity. Biolage ColorLast Shampoo is also not an inhalable product that could lead to inhalation exposure.


It is a non-water-soluble silicone that works by coating the cuticles to add softness and lock in moisture to prevent water loss. However, it may build up on your hair over time since it can’t be washed with water only. It’ll take a few sessions with a clarifying shampoo to remove the residue from your hair.

Guar Hydroxypropyltrimonium Chloride

A water-soluble compound that is partially derived from the guar or cluster bean plants. It is beneficial to help soften your hair and improve hair’s manageability by neutralizing the negative charges of your hair strands that can lead to tangling.

Orchis Mascula Extract

Otherwise known as “early purple orchid” or “early spring orchid”. It is believed to be rich in antioxidant properties that help fight against damaging free radicals which can cause faster color fading. Orchid also has a rejuvenating effect that is beneficial to moisturize your hair.


Commonly found in sunscreen, benzophenone-4 is a water-soluble UVB absorber that blocks out harmful UV rays. Due to its ability to filter UVB, benzophenone-4 is beneficial to help prevent color (both natural and treatment) fading from sun exposure.

However, in Biolage ColorLast Shampoo, this ingredient seems a bit ineffective to be used as a UVB filter since it’ll be rinsed out. That said, you should set an expectation that it may not give you as much benefit in UV protection as you get in sunscreen.

After taking a closer look at the important ingredients, now let’s find out what customers are saying about the Biolage ColorLast Shampoo.

Below, we provide both good and bad reviews from those three platforms to give you a broader and more diverse perspective on the Biolage ColorLast Shampoo.

The Compliments

On Amazon, many users gave major positive responses about the effectiveness of the shampoo that preserves their hair color and delivers softness. Just like this user says:

I bought this product about 2 months ago. My hair was dark purple and now it’s turquoise and when I wash it with shampoo and conditioner it seems like the color lasts longer. Also, my hair doesn’t feel dry. It feels soft being that I have done so much damage to my hair going from dark brown to blonde to now strong colors.”

One user on Ulta also reported that the shampoo did prolong her hair color vibrancy compared to other shampoos she’d used before.

As someone with vibrant purple hair, I’ve found that the Biolage Color Last Shampoo helps keep my purple lasting longer than other shampoos I’ve used. Granted the purple eventually does fade but it keeps it lasting way longer than 3-4 washes, which is what I find other conditioners and shampoos only work till.”

Biolage ColorLast Shampoo seems to help deliver shiny, bouncy-looking hair while maintaining color vibrancy. Here’s what a MakeupAlley user says:

“I’ve tried a lot of shampoos over the last few months, and this one is wonderful. It makes my hair feel bouncy, clean, healthy, and shiny after each use. It’s been a good hair day every time! I do have dyed hair and so far after a few weeks of use every other day, my color is staying put. I am also using it with the matching conditioner, which does a great job as well.”

Here’s another excellent review from Amazon users

My hair remains healthy and shiny even 8 weeks after color to where people think my hair was just done.”

Now, let’s take a look at the negative reviews.

The Complaints

Despite getting tons of praise, some users are also a bit dissatisfied with the shampoo. Below is a negative review of an Amazon user:

It’s definitely not a fake product. A bit pricey for my taste, and it didn’t really deeply condition my thick highlighted hair, but it does smell great.”

One Ulta user showed her disappointment with Biolage which makes her hair dry.

I started using this shampoo because it has good reviews on here and didn’t notice my hair getting drier until about 5 washes. I didn’t realize this has sulfate which is super drying for my hair. I spent a lot on the big bottle and plan to use it up before I find a hydrating, color-safe, sulfate-free shampoo. I do, however, think the conditioner is ok.”

While other people noticed dry hair after using Biolage ColorLast, other ones experienced greasy hair instead just as this MakeupAlley user reports:

This shampoo smells really good however I had a hard time getting it to lather for some reason. My hair seemed harder to straighten and a little limp too but overall.”

Below is the worth-noting review from an Amazon user who complained about broken packaging.

“I have had several bottles crack open and waste shampoo. I love the shampoo but am definitely thinking of changing.”

Based on reviews we sampled online, Biolage ColorLast did work on maintaining hair color, plus it also helped to deliver shiny and healthy hair. However, some users complained about compromised packaging and didn’t see improved hair quality, which makes it not worth the value.

In the next section, we take a look at the disadvantages and possible side effects of Biolage ColorLast Shampoo.

Biolage ColorLast Disadvantages and Side Effects

However, this con is not entirely accurate since water and hair damage play a major role in color fading.

Despite this issue, many users are satisfied with the performance of the product in helping maintain their hair color tone. Given the shampoo may dry out your hair, it is best to use the conditioner to moisturize and detangle after the washing session.
