What the formula actually does
Read from the label, not the marketing
Each row says where it comes from: F means we derived it from this product’s own ingredient list, S means it is a claim the brand makes that the formula neither confirms nor contradicts.
Cleansing strength
Strong
Removes oil, buildup, and most residue — a reset wash.
Expected lather
High
Thick foam that spreads quickly through the hair.
Slip and detangling

Full ingredient list (24)
US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Annotations keep three readings separate: the ingredient's general function, its role in this product type, and what its position can support.

Water
· Aqua/Water/Eau
General function
The base of almost every rinse-off and cream hair product. It carries everything else and is normally the first ingredient on the label.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
- solvent

2
Sodium Laureth Sulfate
General function
A strong, high-foaming cleanser and the most common shampoo detergent. It removes oil and product efficiently, which can be more than dry or colour-treated hair wants.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
Indian Journal of DermatologyMay suitBuild-up-sensitive routinesA sulfate detergent removes deposited silicone, wax and styling films in one wash, which is what resets a routine before build-up is visible.
May suitFine or easily flattened hairFine hair that goes limp under conditioning films usually reads a full detergent wash as volume returning.

Coco-Betaine
General function
A coconut-derived mild cleanser that boosts foam and softens stronger detergents.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May suitDry, coarse, or high-porosity hairMild cleansing leaves more surface lubrication in place on hair that dries out quickly.
May suitVery dry or highly damaged hairOne of the mildest detergent classes. It is usually there to let a formula lather without a harsher detergent doing the work.

Glycerin
General function
A small water-loving molecule that draws moisture into the hair and holds it there. It is the most common softening ingredient in conditioners and leave-ins.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Scientific ReportsMay suitDry, coarse, or high-porosity hairHigh-porosity hair loses water fast; a humectant holds some of it in place for longer than the wash itself would.
May suitVery dry or highly damaged hairBinds water into the outer layers of the strand, and water is what makes dry hair flexible again rather than brittle.
DependsClimate-sensitive or frizz-prone hairWater moves both ways. Measured across concentrations, glycerin solutions give water up in some conditions and take it from the air in others. What it does for you depends on how much of it is there and on the air around it.
- humectant

Glycol Distearate
General function
A wax that gives shampoo its pearly look and a slightly richer feel.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
PubChemMay suitFrizz-prone, damaged, or high-friction hairEmollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

Propylene Glycol
General function
A small humectant and solvent that keeps formulas stable and helps active ingredients spread.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
PubChemMay suitFine or easily flattened hairLight and water-binding rather than oily, so it hydrates without contributing weight.
May suitVery dry or highly damaged hairA small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.
DependsClimate-sensitive or frizz-prone hairA humectant follows the air: it holds water in humid conditions and can give it up in very dry ones. Climate decides what it does more than the label does.

Polyquaternium-10
General function
A cellulose-based conditioning polymer that leaves a thin, static-reducing film. Very common in shampoos as the ingredient that keeps them from stripping.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitCurls or waves needing flexible holdCationic polymers hold a curl loosely and stay soft, which is why they turn up in definition products rather than firm-hold ones.
May suitFrizz-prone, damaged, or high-friction hairA cationic polymer stays on the hair through rinsing, which is what keeps static and combing friction down after the wash.

Fragrance
· Parfum/Fragrance
General function
An undisclosed blend of scent ingredients. Regulations let it stay unlisted, so a fragrance-free product is the only way to be certain what is not in it.

Sodium Hydroxide
General function
A strong base used in trace amounts to raise pH; fully neutralised in the finished product.

International Journal of TrichologyDependsFrizz-prone, damaged, or high-friction hairThe alkali half of a pH-adjusting pair, used in small amounts to bring a formula up to its target rather than to make it alkaline. Alkaline conditions raise the fibre's surface charge and lift the scales — but the finished pH is not on the label.
- pH adjuster

Citric Acid
General function
Used to bring the product to a slightly acidic pH, which helps the cuticle lie flat. It is almost always near the end of the list.

International Journal of TrichologyMay suitBuild-up-sensitive routinesHolds hard-water minerals in solution so they rinse away instead of depositing on the hair.
May suitFrizz-prone, damaged, or high-friction hairThe acid side of pH adjustment, and the reason it matters is measured: alkaline formulas raise the fibre's surface negative charge, increase friction between strands and lift the scales, while lower-pH ones do the reverse.
May suitGray, silver, or brass-prone hairWhere a warm cast comes from water minerals rather than from the hair itself, holding those metals in solution is what removes it.

Carbomer
General function
A thickener that turns a liquid into a clear gel. It also contributes a light hold.
Estimated lower-concentration zoneIt appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
May suitClimate-sensitive or frizz-prone hairA set polymer film is a physical barrier to humidity, so a style keeps its shape longer in damp conditions.

Sorted by price per ounce. Dated observations from our research, not live prices. Direct store pages, no affiliate links. We don’t sell this product.
How we work this out
- 10.1 oz is the size stores list most often; every comparison on this page is made at it. Other sizes are shown in the Sizes row and the store list.
- Commonly seen is the middle half of current prices for the 10.1 oz at recognised stores — the cheapest quarter and the dearest quarter are left out, so one sale or one overpriced listing can’t move it.
- Good value under $9 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $0.90/oz; at 10.1 oz that is $9. Under that line you are paying less than most of them.
- About $17 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 10.1 oz.

Formula score
10 of 10
The formula carries the systems a shampoo is built around, and it sits in the middle of the range for shampoos per ounce.
How the score is counted
- 3 products we score as doing the same job cost less per ounce
- Costs more per ounce than 65% of the 817 shampoos we’ve priced
- Covers 7 of the 7 things a shampoo should do
- Reviewers mention 3 recurring complaints

- Slip for detanglingReduces the force it takes to comb wet hair.2 pts
- A humectantBinds water into the hair.1 pt

- No detergent-dependent filmNothing that needs a clarifying wash to remove.1 pt
- Fragrance kept out of the top eightScent as a finishing touch, not a major share.1 pt
The formula score is completeness for the job: the share of the systems this product type is normally built around that we can find in this list, weighted. It is not efficacy, not quality, and it never compares across product types.
Does the same job, for less
Same derived functions — what it cleans, conditions, coats or holds — at a lower cost per ounce. Scent, texture and where you buy it can still differ.

Claims check

Claims are quoted from the brand. We only mark one supported, partly supported, or conflicting when the ingredient list actually speaks to it; everything else stays "stated by the brand", which is not a criticism — most claims simply cannot be read off a label.

Reviewers
What people report
Recurring themes our researchers wrote in their own words from sourced reviews. We do not store or scrape star ratings.
Reviewers report noticeably reduced breakage and split ends, with hair feeling clean, soft, and smooth after use
A number of long-time customers say the product replaced the discontinued So Long Damage line and prefer the original formula
former So Long Damage usersSome reviewers say hair feels greasy or heavy within 24 hours of use
Reviewers with curly hair report drying effects and poor slip during conditioning that leads to tangles
curly hairSome reviewers report a strong chemical scent that caused an allergic reaction, though most describe the fragrance as pleasant floral/sweet

How this page was made
- Everything above is generated from our researched product record — identity, the ingredient list as printed, the brand's own claims, dated price observations, and review themes written in our researchers' own words. No part of this page is written per product.
- The value band is a fixed label over two stored numbers: this product’s cost per ounce as a percentile of every product of this type we have priced, each at the size it is most often sold in, and how many products we score as doing the same job cost at least a quarter less per ounce.
- Both scores out of ten are defined on this page. The formula score is completeness for the job, computed from a fixed per-format checklist shown beneath the gauge; the price score is cost per ounce against every product of this type we have priced.
- The "Is this right for you?" panel reads only your own consultation answers, and it applies exactly the filters our recommendation engine applies. It is computed when you load the page and is never stored on it.
- 7 sources consulted for this product (6 manufacturer or regulatory, 1 retailer, 0 editorial), last checked 2026-08-25.
- Ingredient references are linked for 10 of 18 product-aware annotations on this page. Fit notes are conditional formulation guidance, not a conclusion about the finished product or about you.
- We have not tested this product in a lab and we do not physically test your hair. Formula readings come from the ingredient list; behaviour claims are labelled as the brand's.
- Ingredient order tells you relative amount only above roughly 1%. Prices are observations on the dates shown and change without notice.
- Ingredient names link to our ingredient library, where each entry shows what it does, which product types use it, and where it usually sits on a label across everything we have researched.
- This is cosmetic information, not medical advice, and nothing here diagnoses or treats a health condition.
- Formula readings: derivation v22. Record last updated 2026-08-25.
