Can a Cosmetic Product Safety Report Back Up Hair Care Claims? The CPSR View on Repair, Strengthen and Salon Quality
Share
The short answer
A Cosmetic Product Safety Report establishes that a hair product is safe and records whether its claims are consistent with the assessment, but it does not by itself prove performance. Cleansing, conditioning, smoothing and reduced breakage are cosmetic effects that can be measured on hair fibres and supported with test data filed in the Product Information File. Repair and strengthen need a named measurement such as tensile strength or combing force. Salon quality and professional are positioning, not claims. Anything about regrowth, hair loss or treating the scalp is medicinal and cannot appear on a cosmetic at all.
Key takeaways
- Hair fibre is dead keratin, so cosmetic claims concern the fibre's surface and structure and the condition of the scalp; growth from the follicle is medicine.
- A CPSR covers safety and claim consistency; performance evidence lives in the Product Information File claims table.
- Repair, strengthen, smooth and reduce breakage are measurable, and a credible brand can name the test in one sentence.
- Salon quality, professional and clinical strength have no definition and support nothing.
- Hero ingredients listed after the preservative are present at fractions of a percent and support only the word contains.
- Anti dandruff products are cosmetics only when presented as controlling visible flakes with permitted actives; treating a scalp condition makes them medicines.
Hair care carries more hero ingredients than any other category, and most of them sit near the bottom of the ingredient list. That is not a scandal; it is the starting point for reading the category honestly. The hair fibre is dead keratin with no living cells, so a cosmetic can clean it, coat it, smooth it, temporarily strengthen it and make it easier to comb, and can clean and condition the living scalp it grows from. Everything beyond that is either measurable performance, marketing positioning, or a medicinal claim that does not belong on a cosmetic. The Cosmetic Products Enforcement Regulations 2013 enforce Regulation (EC) No 1223/2009 and its claims rules in Regulation (EU) No 655/2013, and the Advertising Standards Authority rules on hair advertising regularly.
This article explains what a Cosmetic Product Safety Report can and cannot do for a hair claim, sorts hair claims into four kinds, lists the measurements that support the testable ones, goes product type by product type from shampoo to hair colour with the claims each can carry, explains why salon quality and plant based tell you nothing about performance, shows how to spot a hero ingredient at a garnish level from the ingredient list, draws the medicinal line that stops a cosmetic becoming an unlicensed medicine, works through a repair shampoo in the order an assessor reads it, and sets out how a brand can make hair claims that survive both the CPSR and an ASA complaint.
What can a Cosmetic Product Safety Report do for a hair claim?
Three things. It confirms the product is safe for its intended and foreseeable use, including scalp contact, eye contact during rinsing and ingestion risk for children where relevant. It applies the annex conditions, which matter enormously in hair care because hair dye substances, hydrogen peroxide, thioglycolates and several anti dandruff actives are restricted with maximum levels and mandatory warnings. And it records whether the claims made for the product are consistent with the assessment, striking anything medicinal or unsupported. What a CPSR does not do is prove that a conditioner makes hair thirty percent easier to comb; that is a performance claim, and its evidence belongs in the Product Information File claims table alongside the report.
The four kinds of hair claim
| Kind | Examples | What it needs | Where it lives |
|---|---|---|---|
| Testable performance | Reduces breakage, easier to comb, adds shine, smooths frizz, strengthens, repairs damage, protects from heat, colour protection | A named measurement on the finished product with a stated duration and sample size | Claims table in the Product Information File |
| Positional | Salon quality, professional, clinical strength, stylist approved | Nothing; lawful only if not misleading | Marketing, and nowhere else |
| Origin and absence | Plant based, natural, with rosemary oil, sulfate free, silicone free, clean | Truthfulness about the origin or absence, with no implied performance or safety benefit | Ingredient list, and the claims table if a percentage is claimed |
| Medicinal | Regrows hair, stops hair loss, stimulates follicles, treats dandruff, cures scalp conditions | Cannot appear on a cosmetic; the product would be a medicine | Nowhere; the assessor strikes it |
In practice
Sort every claim on the bottle into one of these four. Only the first can be checked, the second is noise, the third is description, and the fourth is the one that turns a cosmetic into an unlicensed medicine.
Which hair claims can actually be measured?
More than most people expect, which is why the good brands in this category are so specific. Strength is measured by tensile testing of fibres before and after treatment. Breakage is measured by counting broken fibres after repeated combing or brushing of treated and untreated tresses. Combability is measured as the force needed to comb wet and dry hair. Shine is measured by goniophotometry, which quantifies reflected light. Frizz and smoothness are measured by image analysis of tresses held at controlled humidity. Heat protection is measured as fibre damage after repeated heat exposure with and without the product. Colour protection is measured as colour retention across a number of washes. Repair, the most contested word in the category, can be measured as restoration of strength or cuticle condition on deliberately damaged hair, and a brand claiming it should be able to say what damage, how measured and how much improved. A brand with real evidence names the method in one sentence; a brand without changes the subject.
Product type by product type
| Product | What the CPSR focuses on | Claims it can carry with evidence | Claims it cannot carry |
|---|---|---|---|
| Shampoo | Eye irritation potential, scalp contact, preservation, rinse off exposure | Cleanses, gentle cleansing with named mild surfactants, colour safe with retention data | Treats dandruff, stops hair loss, repairs without a test |
| Conditioner and mask | Leave on or rinse off exposure, preservation, allergens | Detangles, easier to comb with force data, adds shine with measurement, reduces breakage with counts | Rebuilds hair, feeds the hair, repairs damage without data |
| Leave in and styling | Leave on exposure over large surface, aerosol inhalation where relevant | Heat protection with a damage study, hold, frizz control with humidity testing | Strengthens without tensile data, thickens hair follicles |
| Hair oil and scalp oil | Anhydrous stability, oxidation, sensitising constituents in essential oils | Conditions, adds shine, softens | Stimulates growth, treats scalp conditions, reduces hair loss |
| Anti dandruff | Permitted active level and conditions, scalp exposure, warnings | Controls visible flakes where the active is permitted and presented cosmetically | Treats seborrhoeic dermatitis or psoriasis, cures dandruff |
| Hair colour and bleach | Annex III maximum on head concentration after mixing, mandatory warning block, peroxide limit | Colour performance, grey coverage with a test | Gentle or hypoallergenic on a product carrying the allergy alert block; ammonia free implying safety |
| Relaxer and perm | Thioglycolate or hydroxide limits, strict warnings | Straightens or waves as directed | Damage free, safe for all hair types without data |
What do salon quality, professional and plant based tell you?
Salon quality describes an aspiration and professional describes a channel; neither says anything about what the product does, and a Cosmetic Product Safety Report neither supports nor refuses them because they make no factual assertion about performance or safety. Clinical strength is more troublesome, because it implies a test or a potency, and an assessor will ask what clinic and what strength. Plant based and natural describe origin, which is legitimate to state and says nothing about mildness: plant derived surfactants can be strong cleansers, and several natural essential oils are among the more potent sensitisers the assessor caps. Essential oils in hair care are fragrance, contributing scent and declared allergens rather than treatment, and claims that rosemary or peppermint oil thickens hair or stimulates the scalp are medicinal claims wearing a botanical coat.
How do I spot a hero ingredient at a garnish level?
Read the ingredient list in order. Ingredients above one percent appear in descending order of weight, so in a shampoo the first names will be Aqua and two or three surfactants, and in a conditioner Aqua, a fatty alcohol and a conditioning agent. A hero ingredient in that opening group is a real component of the product. A hero ingredient listed after the preservative and the fragrance is present at a fraction of a percent and, in a product that spends thirty seconds on the hair before being rinsed away, does very little. Keratin, biotin, collagen, caffeine and most botanicals occupy that position in the majority of products that name them on the front. That is lawful so long as the claim made about them is proportionate, and proportionality is exactly what the assessor checks: an ingredient present at a garnish level supports the word contains and nothing stronger.
Ask yourself
Find the ingredient named on the front of your bottle in the list on the back. If it sits after the preservative, what exactly is the front of the pack claiming, and what evidence is in the file for it?
Where does the medicinal line fall?
At the follicle and at disease. Claims to regrow hair, stop or reverse hair loss, stimulate follicles, or treat, cure or relieve a scalp condition such as seborrhoeic dermatitis, psoriasis or eczema make a product a medicine by presentation, and no Cosmetic Product Safety Report can be written for a medicine sold as a cosmetic. Anti dandruff products are the recognised borderline: they remain cosmetics when presented as controlling visible flakes and using actives permitted in the annexes at permitted levels, and become medicines when presented as treating a scalp disease. Licensed hair loss medicines exist and are regulated under medicines law with marketing authorisations, which is why a consumer comparing hair loss products is comparing two legal categories before comparing two levels of evidence. An assessor who sees a medicinal claim on draft hair artwork will strike it, and a brand that prints it anyway is trading unlawfully.
A repair shampoo, read in the order an assessor reads it
The artwork says salon quality repair shampoo with keratin and argan oil, sulfate free, plant based, for stronger, healthier hair. Part A section 1 gives the formula: Aqua, Coco-Glucoside, Lauryl Glucoside, Cocamidopropyl Betaine, Glycerin, then a preservative, then Hydrolyzed Keratin, then Argania Spinosa Kernel Oil last. Section 10 asks for claim evidence and receives none. The assessment proceeds: the product is safe, eye irritation potential is acceptable for a rinse off, the preservative system passes its challenge test. Then the claims. Salon quality is positional and survives as marketing. Repair and stronger are performance claims with no test and are struck. Healthier is a vague wellbeing word with no measure and is struck. With keratin and argan oil survives as a contains claim, since both are present, but cannot support repair. Sulfate free is true and, because the glucoside surfactants genuinely are milder, the brand is advised to make the positive claim instead: formulated with mild plant derived cleansers. Plant based is supported by the surfactant origins. The revised front says gentle plant derived cleansing shampoo with keratin and argan oil, and the brand books a combing force study if it wants to say more. The formula never changed.
What about hair claims on social media and in salons?
The same rules apply wherever the claim is made. A cosmetic claim is judged on the overall impression given to the consumer, which includes a brand's own posts, its paid advertising, its influencer briefs and the wording on a stylist's shelf card. An assessor reviewing draft artwork sees only the pack, so a brand can pass the Cosmetic Product Safety Report and still be making unlawful claims on Instagram, and the Advertising Standards Authority rules on exactly those cases. The practical answer is to keep one claims table covering every channel, to brief influencers with the approved wording rather than a free hand, and to treat a reposted customer testimonial claiming that a product cured their scalp condition as a claim the brand has adopted, because that is how it will be read.
How should a brand make hair claims that survive?
• Claim what the formula delivers. Cleanses gently, conditions, detangles, adds shine.
• Test before claiming performance. Combing force, breakage counts or tensile testing on the finished product, and say so on the page.
• Put hero ingredients at working levels, or claim only that they are present.
• Use origin words descriptively. Plant derived surfactants; scented with rosemary essential oil.
• Replace absence claims with the positive claim they imply.
• Keep medicinal language off every hair product. Growth, loss, follicles and named scalp conditions.
• Respect the hair colour warning block. Gentle and hypoallergenic claims sit badly beside a mandatory allergy alert.
Keep the claims table in the Product Information File and review it annually.

Myths we hear
• Keratin in a shampoo rebuilds hair. At garnish levels in a rinse off product it supports contains, not repairs.
• Essential oils treat the scalp. At cosmetic levels they scent the product and add declared allergens.
• Sulfate free means gentle. The replacement surfactants decide that, and they should be the claim.
• Salon quality implies testing. It implies a channel.
• A CPSR proves my product works. It proves your product is safe and that your claims are consistent; performance evidence is separate.
What to do this week
• Sort every claim on your hair range into the four kinds.
• Find each front of pack ingredient in the list and check its position.
• For every performance claim, write down what was measured, how and on how many.
• Strike every medicinal word from labels, pages and social posts.
• Send the revised artwork to your assessor with the next submission.
Hair claims become easy to judge once you accept that the hair is dead and the scalp is skin. Everything honest follows from that, and the Cosmetic Product Safety Report is where the honest version is written down. You can verify any Spectra report and ask our assessors about a claim before you print it.
