Kristin Ess built a small lineup that punches above its weight, with shampoos for curls, sensitive scalps, brass-prone blondes, oily roots, and everything in between. Picking the right bottle often comes down to your texture, color, and how often you wash.
The shortest path to a good match is knowing what your hair actually does on wash day: does it frizz up, fall flat, itch, or build up fast. From there, this list walks through the trade-offs of each formula so you land on one that earns its shelf space.

A Deeper Look At The Lineup
If your hair lives anywhere from loose waves to tight coils, this Moisture Rich Curl Shampoo is built around the reality that curly textures often dry out faster than other hair types. The formula is lightly clarifying, which means it lifts build-up without stripping the natural oils your curls lean on for definition.
At 33.8 fl oz, this is the family-room-size bottle that tends to outlast a couple of months even for daily washers. The curl range on the label, 2A through 4C, covers everything from soft S-waves to springy coily textures, so you don’t have to second-guess whether it fits your pattern.
What It Does Well
- Castor oil and shea butter help lock in moisture through wash day, leaving curls softer instead of straw-like.
- Free of sulfates, parabens, and silicones, which matters for anyone avoiding heavy coatings that dull curl shape.
- Light clarifying action means you can use it as your regular wash without needing a separate detox step.
- The 33.8 fl oz size keeps the per-wash cost down, helpful for households that wash curly hair frequently.
Things To Consider
- On very fine, low-density curls, the richer formula can feel like it weighs strands down, depending on how much you use.
- Owners with hard water commonly report a faint residue over time, so a monthly clarifying rinse helps keep things balanced.
Made For
Wavy to coily textures (2A-4C) that want a sulfate-free daily wash with built-in moisture and minimal frizz.
Consider Something Else When
Your hair is fine, oily, or scalp-reactive, in which case the gentler Kristin Ess Hair Extra Gentle Shampoo for Sensitive Scalp 10 fl oz is the safer match.
The Signature Shampoo sits in the middle of the Kristin Ess range, designed as a daily, sulfate-free wash that doesn’t pick favorites between straight, wavy, or color-treated hair. It’s a sensible pick when you want one bottle in the shower that handles whatever your week throws at it.
Avocado oil and castor oil show up here in small but meaningful amounts, lending slip without making fine hair feel coated. At 33.8 fl oz, it stretches further than most daily washes, and it stays color-safe so you don’t have to switch bottles after a salon visit.
The Case For It
- The universal formula means a shared bathroom can stock just one shampoo for multiple hair types.
- Color-safe and keratin-safe, so it won’t shorten the life of fresh color or smoothing treatments.
- The vegan, sulfate-free formula is gentle enough for frequent washing, even on dry ends.
- Large 33.8 fl oz bottle lowers cost per wash, helpful for daily shower routines.
Worth Noting
- It doesn’t target any specific concern, so if you need real curl definition or brass correction, a more specialized bottle will do more for you.
- The light hydration won’t satisfy very thick or curly hair on its own, where the curl-specific Moisture Rich formula tends to perform better.
Quick Facts
Right Fit For
Everyday washers with straight to wavy hair, color-treated hair, or anyone who wants a single bottle that flexes across hair types in the household.
Reach For A Different Pick When
Your main concern is defined, frizz-free curls, in which case the larger Kristin Ess Moisture Rich Curl Shampoo for Wavy to Tight Curls 2A-4C is the more targeted option.
For anyone whose scalp protests louder than the rest of their hair, this Extra Gentle Shampoo is one of the quietest formulas in the Kristin Ess lineup. The fragrance is subtle, the surfactant system is mild, and the finish is described as weightless, which adds up to a calmer wash day for reactive skin.
It also doubles as a moisture pick for dry hair that gets crunchy or straw-like with harsher shampoos. At 10 fl oz, the bottle is a travel-friendly size that fits easily in a gym bag or carry-on.
What Earns Its Place
- Mild surfactant blend is well suited to scalps that itch, flake, or react to stronger cleansers.
- Subtle fragrance is easier on people bothered by stronger scents in the shower.
- Color-safe and keratin-safe, so it plays well with salon work and chemical treatments.
- Vegan formula with a gentle moisturizing profile keeps hair soft without heavy residue.
Room For Improvement
- Smaller 10 fl oz size runs out faster than the 33.8 fl oz bottles, which adds up for daily washers.
- The gentle cleanse can feel underpowered on hair with heavy styling-product build-up, where a clarifying shampoo would do better.
Who It Suits Best
Anyone with a reactive, itchy, or easily irritated scalp who wants a fragrance-light, sulfate-free daily wash.
Look Elsewhere When
Your main issue is oily roots and product build-up, in which case the Kristin Ess Deep Clean Clarifying Shampoo for Oily Hair is built for that job.
The travel-size sibling of the larger curl shampoo gives you the same curl-targeted, lightly clarifying formula in a 10 fl oz bottle. It’s a smart way to test the Moisture Rich line before committing to a bigger pump, or to keep a backup in your gym bag.
The blend still leans on gentle cleansing and good slip, so wash day stays short for curls that tangle easily. Compared with the 33.8 fl oz curl bottle, the trade here is purely about size and shelf space, not formula strength.
Noteworthy Benefits
- Smaller bottle is easy to toss in a weekender, gym locker, or hotel bathroom.
- Same curl-friendly formula, so you don’t sacrifice moisture or anti-frizz performance for portability.
- Sulfate, paraben, and silicone-free for curl routines that avoid those ingredients.
- Light clarifying action keeps curls clean without drying them out, even on busy wash schedules.
Honest Caveats
- Run out faster than the larger 33.8 fl oz curl bottle, so the per-wash cost runs higher for daily users.
- Not as practical for households where multiple people share one shampoo bottle.

Best Suited To
Curl-wearers who want to try the Moisture Rich formula in a small bottle, plus travelers and gym-goers who need a portable curl wash.
Swap It Out When
You wash daily and want to cut down on reordering, since the larger Kristin Ess Moisture Rich Curl Shampoo for Wavy to Tight Curls 2A-4C is the better value per wash.
The One Purple Shampoo is Kristin Ess’s brass-neutralizing formula, sold here as a two-pack of 33.8 fl oz bottles. Purple shampoos work by depositing violet pigment (a pigment that cancels out yellow tones on the color wheel) to balance unwanted warmth in blonde, silver, or highlighted hair.
Going sulfate-free matters here because harsher surfactants can strip cool tones out of color-treated hair almost as fast as they tone it. The two-pack is built for households or stylists who use purple shampoo often enough to want a backup on hand.
Useful Strengths
- Neutralizes brass and yellow tones without the drying feel of stronger purple formulas.
- Sulfate-free formula is kinder to color-treated, bleached, or highlighted hair.
- Two-bottle pack reduces the hassle of reordering for regular toning routines.
- Works on both cool blondes and brunettes who want to dial down orange or yellow undertones.
Points To Keep In Mind
- Used too often, purple shampoo can over-tone, leaving a faint lavender cast, especially on very porous or platinum hair.
- Two large bottles take up significant shelf or storage space in smaller bathrooms.
Who Will Love This
Regular toning routines for blondes, silvers, balayage, and highlighted brunettes who want a sulfate-free purple shampoo in a value-sized two-pack.
A Better Fit Elsewhere
You only tone occasionally and want a smaller bottle, in which case the 10 fl oz Kristin Ess Hair The One Purple Shampoo is easier to store.
Clarifying shampoos are designed to remove the gunk that regular shampoos leave behind, and this Deep Clean version is the strongest reset in the Kristin Ess lineup. It’s formulated to lift mineral deposits, excess oil, and silicone build-up that can leave hair flat or waxy over time.
The brand describes it as a “when you need it” shampoo, not an everyday wash, which keeps expectations realistic. For thick, curly, or color-treated hair that struggles with residue, it’s a useful reset button between regular wash days.
Key Advantages
- Targets product build-up, mineral deposits, and excess oil in a single wash.
- Suitable for thick, curly, and color-treated hair, where build-up tends to weigh strands down.
- Vegan, sulfate-free formula lifts residue without leaning on the harshest surfactants.
- Works as a periodic reset between regular shampoos, helping other formulas do their job better.
Points To Note
- Not designed for daily use; overuse can leave hair feeling dry, especially on already-dry ends.
- Won’t replace a moisturizing shampoo, so most routines pair it with a gentler daily wash.
Technical Highlights
Built With In Mind
Oily, product-heavy, or thick and curly hair that needs a periodic clarifying reset rather than a daily cleanser.
Not Your Match When
Your hair is already dry or color-treated and you need a gentle daily wash, since the Kristin Ess Hair One Signature Shampoo 33.8 fl oz handles that routine better.
The 10 fl oz size of The One Purple Shampoo is the easier, lower-commitment way to try a purple shampoo before scaling up. It uses the same brass-neutralizing, sulfate-free approach as the larger bottles, just in a friendlier size for occasional toning.
It’s also free of silicones and parabens, so you don’t have to worry about layering heavy ingredients on top of color-treated hair. For most blondes and silvers, that means a clean tone without a waxy finish.
Positive Points
- Compact 10 fl oz size suits smaller bathrooms and travel kits.
- Sulfate, silicone, and paraben-free formula keeps color-treated hair from getting overloaded.
- Color-safe and keratin-safe, so it pairs well with smoothing or chemical treatments.
- Shine-restoring finish helps blondes look less dull between toning sessions.
Trade Offs
- Runs out faster than the 33.8 fl oz bottle for anyone toning weekly.
- Small size isn’t ideal for households that share one bottle across multiple users.
Perfect Match For
Blonde, silver, or highlighted hair that only needs occasional toning, plus anyone wanting a smaller bottle to start with.
Where A Sibling Pick Shines
You tone regularly and want fewer reorders, since the 33.8 fl oz Pack of 2 of Kristin Ess Hair The One Purple Shampoo gives you more bottles for less hassle.
Micellar shampoos borrow from micellar water (a cleansing water that uses tiny surfactant molecules to lift impurities without stripping) to gently pull oil and residue away from the scalp. This Scalp Purifying version leans into that idea for build-up-prone roots.
The brand notes it works across hair types, from fine, thin strands to thick, curly textures, which is unusual for a scalp-focused formula. The 10 fl oz bottle is also vegan, sulfate-free, color-safe, and keratin-safe, so it slots into most routines without a conflict.
What Works In Its Favor
- Micellar water technology lifts impurities without leaving the scalp feeling dry or tight.
- Shine-boosting, strand-fortifying finish supports hair that looks dull from product build-up.
- Color-safe and keratin-safe, so it won’t shorten the life of salon work.
- Vegan, sulfate-free formula fits routines that avoid animal-derived or harsher surfactants.
A Few Limitations
- Smaller 10 fl oz size means you’ll reorder more often than the 33.8 fl oz bottles.
- Won’t replace a heavy-duty clarifying wash for very oily, product-heavy hair where the Deep Clean Clarifying Shampoo does more.
Feature Rundown
Whose Shelf It Belongs On
Anyone whose main frustration is scalp build-up and dull roots, especially people with fine hair that gets weighed down fast.
Skip It When
Your hair is oily all the way to the ends and needs a deeper reset, where the Kristin Ess Deep Clean Clarifying Shampoo for Oily Hair is the stronger match.
This two-pack of the 10 fl oz Deep Clean Clarifying Shampoo is the grab-and-go version of the larger detox bottle. Two smaller bottles travel better than one big one, and they’re easier to stash in a gym bag, suitcase, or guest bathroom.
The formula itself does the same job as the larger clarifying bottle: it lifts build-up, oil, and dirt from hair and scalp so your regular shampoo can do its job. It’s still vegan and sulfate-free, so the clean isn’t coming at the cost of harsher surfactants.
Features That Help
- Two 10 fl oz bottles are easier to travel with than one large bottle.
- Works as a periodic reset for oily, product-heavy, or hard-water-exposed hair.
- Vegan and sulfate-free formula lifts build-up without relying on harsh surfactants.
- Smaller bottles fit in tight shower storage and shared bathrooms.
Less Ideal Details
- For most people, two small bottles cost more per ounce than the larger single bottle.
- Not built for daily use, so you still need a separate gentle wash for in-between days.
Right Fit For
Travelers, gym-goers, or households that want a clarifying backup in two smaller bottles rather than one large one.
Where Another Pick Suits Better
You want one bigger bottle at home instead of two smaller ones, where the larger Kristin Ess Deep Clean Clarifying Shampoo for Oily Hair is the more efficient option.
What Matters Most Before Choosing Kristin Ess Shampoos
Start with your hair type, because most Kristin Ess formulas are designed around a specific texture or concern rather than a single universal fix. Wavy-to-coily hair usually does best with the Moisture Rich Curl line, while straight or color-treated hair tends to do well with the Signature Shampoo.
Next, think about your scalp. If your scalp tends to itch, flake, or react to fragrance, the Extra Gentle formula is the safer bet. If your roots get oily or waxy fast, a clarifying or micellar option will reset things faster than a daily moisturizing wash.
Finally, look at the ingredient list you actually want to avoid. The line is broadly sulfate-, paraben-, and silicone-free, but the curl and toning formulas go further by skipping extra coatings that can weigh curls down or dull blonde tones. Matching these filters to your habits is usually the fastest path to a bottle that earns its place.
Key Considerations Across These Picks
Where Shoppers Go Wrong
A common slip is grabbing a purple shampoo and using it every wash. Purple pigment builds up fast, and overuse can leave blonde or silver hair looking dusty or lavender. Treating it as a once-a-week reset rather than a daily wash keeps tones balanced.
Another trap is using a heavy curl shampoo on fine, low-density hair. The richer Moisture Rich formula that works beautifully on 3C and 4C coils can flatten thinner curls if you use too much. Reading the texture range on the label before you commit saves a return trip later.
When Paying More Pays Off
The bigger 33.8 fl oz bottles and two-packs cost more up front, but they tend to lower the per-wash price for daily shower routines. They’re also worth it when you know you’ll use a formula often, like a weekly purple shampoo or a curl wash on shared hair days. For occasional toning or travel, the smaller bottles make more sense.
Frequently Asked Questions
Are Kristin Ess shampoos safe for color-treated hair?
Most formulas in the line are color-safe and keratin-safe, including the Signature, Curl, Extra Gentle, and Purple options. The clarifying shampoo is also sulfate-free, though it functions as a deeper reset, so you’ll want to use it sparingly on freshly colored hair.
How often should you use a clarifying shampoo?
For most people, once every week or two is enough to lift product and mineral build-up. Daily use can leave ends dry, so pairing a clarifying wash with a gentler daily shampoo is the more balanced routine.
Which Kristin Ess shampoo works for curly hair?
The Moisture Rich Curl Shampoo line covers the full curl range, 2A through 4C, with castor oil and shea butter in the formula. The 33.8 fl oz bottle suits daily home use, while the 10 fl oz version is easier for travel or testing the formula first.
Is purple shampoo safe for brunettes?
Yes, the purple formula can help neutralize orange or yellow undertones in highlighted or balayaged brunette hair. For full brunettes without highlights, results can be subtle, so you’ll want to use it only when warmth shows up.
Can you use Kristin Ess shampoo every day?
The Signature, Curl, and Extra Gentle formulas are gentle enough for daily washing on most hair types. The clarifying and purple formulas are better saved for occasional use to avoid stripping color or over-toning.
Closing Remarks
The best Kristin Ess shampoo for you comes down to matching the formula to your texture, scalp, and color situation rather than chasing a one-size-fits-all bottle. Curl-patterned hair usually lives in the Moisture Rich line, sensitive scalps do better with Extra Gentle, and brass-prone blondes reach for The One Purple. Clarifying and micellar options earn their place as periodic resets between daily washes.
