Introduction
If you have invested time and money into balayage, highlights, an all over dye job, or another color service, choosing the right shampoo matters. So, is Monday Hair Care color safe? Yes. MONDAY Haircare says its products can be used on color treated and dyed hair, and its formulas are made without SLS and parabens. The brand specifically recommends its GENTLE range for treated hair that needs extra care.
However, there is an important distinction between being color safe and being specifically designed to protect color. MONDAY has offered a COLOR PROTECT shampoo and conditioner designed for color treated hair, with ingredients such as amino acids, coconut oil, shea butter, vitamin E, and jojoba oil.
Here is what you should know before choosing a MONDAY shampoo and conditioner for your dyed hair.
What Does Color Safe Actually Mean?
A color safe shampoo is generally formulated to cleanse hair while being less likely to contribute to premature color fading than a harsh cleansing routine.
It does not mean that your hair color will never fade. Hair color naturally changes over time because of washing, heat, UV exposure, styling, water quality, and the chemistry of the original color service.
For someone with color treated hair, useful features include:
- A relatively gentle cleansing system
- No SLS
- No parabens
- Conditioning ingredients
- A formula suited to the hair’s texture and condition
- Good moisture retention
- Reasonable washing frequency
MONDAY’s current brand information says its shampoo and conditioner formulas are pH balanced, dermatologically tested, and free from SLS and parabens.
Is Monday Hair Care Color Safe for Dyed Hair?
Yes. MONDAY Haircare states that its products are suitable for color treated and dyed hair. The company says it has received positive feedback from people with color treated hair and recommends the GENTLE range for treated hair that needs additional TLC.
This makes MONDAY a reasonable option if you have highlights, balayage, ombré, permanent color, or other dyed hair.
There is also a useful distinction to make. Not every MONDAY product has exactly the same purpose.
For example:
| MONDAY range | Best suited to | Color treated hair |
|---|---|---|
| SMOOTH | Curly, wavy and frizzy hair | Suitable |
| MOISTURE | Dry, coarse and coily hair | Suitable |
| VOLUME | Thin, fine and oily hair | Suitable |
| REPAIR | Dry and damaged hair | Suitable |
| COLOR PROTECT | Color treated hair | Specifically designed for it |
The current MONDAY range lists SMOOTH, MOISTURE, VOLUME and REPAIR in its U.S. lineup, while MONDAY’s international sites also list COLOR PROTECT.
That means choosing a product should depend on both your color treatment and your hair type.
Why MONDAY Can Work for Color Treated Hair
One of the strongest points in favor of MONDAY is its cleansing approach.
MONDAY says its products do not contain SLS and instead use alternative cleansing agents. The U.S. FAQ explains that its shampoos use cleansers such as sodium olefin sulfonate and sodium cocoyl isethionate to create lather without SLS.
The brand also states that its full range is free from SLS and parabens.
That does not automatically make every shampoo perfect for every dyed head of hair. Your individual hair condition still matters.
For example, recently bleached hair may be much drier and more fragile than untreated hair. In that situation, a moisturizing or gentle formula may be more useful than simply choosing a shampoo because it says color safe.
Monday Smooth Shampoo and Conditioner for Colored Hair
If your color treated hair is also wavy, frizzy, or difficult to manage, MONDAY SMOOTH is worth considering.
The current SMOOTH formula includes hydrolyzed wheat protein, avocado oil and conditioning ingredients. MONDAY positions the range for curly, wavy and frizzy hair.
This is particularly relevant if your color service has left your hair feeling rough or less manageable.
The conditioner contains ingredients such as shea butter and coconut oil alongside conditioning agents designed to improve softness and manageability.
For someone with highlighted or balayage hair that also has natural waves, this can make more sense than selecting a shampoo based solely on oil control or volume.
What About Monday Color Protect?
COLOR PROTECT is the most obvious MONDAY choice when color preservation is your main concern.
MONDAY describes the range as being made specifically for color treated hair. Its formula includes essential amino acids along with coconut oil, shea butter, vitamin E and jojoba oil. The brand says the combination is intended to help prevent unnecessary color fading while supporting shine and vibrance.
The shampoo and conditioner are also listed as:
- Sulfate free
- Paraben free
- Cruelty free
- Dermatologically tested
- pH balanced
- Suitable for color treated hair
Amino acids are particularly relevant because they are associated with supporting hair’s protein structure, while conditioning ingredients can help improve the feel and appearance of processed hair.
Is Monday Hair Care Good for Different Hair Types?
Yes, but the best product depends on your hair’s needs.
MONDAY currently positions its core ranges for different hair types and concerns. SMOOTH is aimed at curly, wavy and frizzy hair, MOISTURE at dry, coarse and coily hair, VOLUME at thin, fine and oily hair, and REPAIR at dry to damaged hair.
For Thick Hair
Thick hair often benefits from conditioning and moisture rather than aggressive cleansing.
If your thick hair is also colored and feels dry, MOISTURE or another more nourishing option may be preferable.
For Wavy Hair
SMOOTH is particularly relevant because MONDAY recommends it for curly, wavy and frizzy hair. The brand also says SMOOTH and MOISTURE are its preferred options for curls and frizz.
For Fine or Oily Hair
VOLUME is designed for thin, fine and oily hair. It contains hydrolyzed collagen and conditioning ingredients intended to provide lightweight moisture.
For Damaged Hair
If your hair has been lightened, bleached, or repeatedly colored, REPAIR may be more relevant than VOLUME because MONDAY specifically positions it for dry to damaged hair.
Ingredients: What Should Color Treated Hair Look For?
When evaluating color safe hair care, do not focus on a single ingredient.
Look at the complete shampoo formula.
MONDAY’s current products commonly combine cleansing agents with conditioning and moisturizing ingredients. For example, the SMOOTH shampoo includes avocado oil and hydrolyzed wheat protein, while the MOISTURE formula includes hyaluronic acid and shea butter.
MONDAY also confirms that its products are vegan and cruelty free and that the range is made without SLS and parabens.
For color treated hair, I would pay particular attention to:
- How dry your hair feels after washing
- Whether your color appears to fade quickly
- Whether your scalp becomes oily between washes
- Whether your hair is bleached or simply dyed
- Whether you need moisture, volume, repair, or frizz control
This approach is more useful than choosing a shampoo simply because the bottle says “color safe.”
Is Monday Haircare Actually Salon Quality?
MONDAY markets itself as affordable luxury and describes its products as salon quality without the traditional salon price point. Its brand ethos also highlights recyclable packaging and cruelty free credentials.
The packaging is another recognizable part of the brand. MONDAY says its pink bottles are 100% recyclable and made using recycled materials.
That gives MONDAY an appealing position between traditional drugstore hair care and more expensive prestige products.
Still, “salon quality” is a marketing positioning rather than a guarantee that every formula will outperform a professional product. Hair responds differently to ingredients, texture, porosity, color treatment, and washing habits.
Is Monday Hair Care Worth It for Colored Hair?
For many people, yes.
The strongest reasons are its SLS free and paraben free positioning, variety of formulas, and dedicated options for different hair concerns. MONDAY also specifically confirms that its products can be used on color treated and dyed hair.
However, if your number one priority is minimizing color fading, choose a formula intended specifically for color treated hair when it is available to you.
If your priority is frizz, moisture, fine hair, or damage, choose the MONDAY range that addresses that problem instead.

Monday Hair Care Lawsuit Update
Some readers searching for MONDAY may also see references to a Monday shampoo lawsuit.
The case was Silvia Garcia v. Zuru, LLC, filed in the U.S. District Court for the Central District of California in July 2025. The lawsuit concerned allegations about the amount of unused space inside MONDAY shampoo packaging, rather than allegations that the shampoo was unsafe for colored hair.
On December 9, 2025, the court entered judgment dismissing the case. The plaintiff’s claims for injunctive relief were dismissed without prejudice for lack of standing, while the remaining claims were dismissed with prejudice.
So, the lawsuit should not be presented as evidence that MONDAY shampoo damages hair or makes color fade.
