Two items on a federal to-do list could eventually change what is sold in salons and what is printed on the back of your lotion. The Food and Drug Administration has signaled plans to propose a ban on formaldehyde in hair straightening products and to propose a rule on labeling fragrance allergens. Both are proposals still ahead of us, not final rules.
In this article, we will explore what the agenda says, how the rulemaking process works, what remains unknown, and how to shop sensibly while you wait.
The Agenda Entries and Where They Come From
The news comes from the semiannual Regulatory Plan and Unified Agenda, a document that federal agencies publish to tell the public which rules they hope to work on in the months ahead. The latest edition appeared on July 3, 2026. A regulatory news service called ChemLinked summarized the cosmetics-related entries on July 9, and an explainer from Dermstreet, last reviewed on October 29, discussed them for a consumer audience. It is worth noting that the Dermstreet piece relies on secondary sources and does not link to FDA documents, so the details here rest on the agenda listing as relayed by those outlets rather than on an FDA press release.
According to those summaries, FDA lists a target of November 2026 for issuing a Notice of Proposed Rulemaking on two separate topics. The first would prohibit formaldehyde, along with chemicals that release formaldehyde, in hair smoothing and hair straightening products. The second is titled “Disclosure of Fragrance Allergens in Cosmetic Labeling” and would carry out the fragrance allergen labeling provisions of the Modernization of Cosmetics Regulation Act, usually shortened to MoCRA.
The single most important word in all of this is “planned.” An agenda date is a target, not a promise. Agencies routinely miss these dates, sometimes by a few weeks and sometimes by years, and an entry can disappear from one edition to the next without any announcement. Nothing has been proposed yet in the formal sense, nothing is binding, and nothing on a store shelf or in a salon has to change today. If you read a headline that says FDA “bans” formaldehyde in hair straighteners, treat it as premature.
What a Proposal Is and Is Not
A Notice of Proposed Rulemaking is the agency’s draft. It describes the rule FDA is considering, explains its reasoning, and invites the public to respond. It has no legal force on its own. Companies that make or sell the affected products are not required to comply with a proposal, and enforcement cannot be based on it. Think of it as a published rough draft with the agency’s name on it.
Why the Timing Deserves Skepticism
Because the November target is so close, readers may expect an announcement within weeks. That is possible, but a cautious reading is better. The agenda is a forecast of intent, and the proposals still have to clear internal and administrative review before they are released. Any of those steps can take longer than hoped. The responsible approach is to watch for the actual publication of the proposal and treat everything before that as a plan.
Formaldehyde in Smoothing Treatments and the Proposed Prohibition
Hair smoothing and straightening treatments are the products at the center of the first proposal. They are typically applied in a salon or at home, left on the hair for a period, and then sealed in with a flat iron or other heat tool. The heat is the key detail, because the agenda language describes products that are applied to hair and heated under their intended conditions of use. That wording points to the moment when problems tend to arise.
How These Treatments Work
Many long-lasting smoothing treatments work by coating the hair shaft and setting a straighter shape with heat, in a way that is reminiscent of how a press holds a pleat in fabric. Some formulas have relied on formaldehyde or on ingredients that slowly or rapidly release it to lock that shape in place. The result can be hair that stays smoother for weeks or months, which explains why the category has been popular, and why manufacturers have been tempted by the chemistry.
Why Methylene Glycol Appears in the Proposal
The agenda names methylene glycol as an example of a formaldehyde-releasing chemical. In plain terms, methylene glycol is what formaldehyde becomes when it is dissolved in water, and it can turn back into formaldehyde gas when heated. That is how a product can avoid listing formaldehyde on the label and still expose people to it during a flat-ironing step. Including both formaldehyde and its releasers in the proposed prohibition closes that loophole on paper, since a ban that named only the pure chemical would be easy to sidestep by reformulating.
What a Prohibition Would Cover
Based on the agenda language, the target is a narrow product class: hair smoothing and hair straightening products that are heated as part of normal use. It does not describe a ban on every product that contains a preservative, and it does not, from what has been reported, reach shampoos, conditioners or ordinary styling products. Whether the eventual text would draw the line exactly there is unknown until it is published. The details of definitions matter enormously in rulemaking, and the final scope can be narrower or broader than an agenda summary suggests.
Formaldehyde itself is well documented as an irritant to the eyes, nose, throat and skin, and international cancer research bodies have classified it as a human carcinogen. Those are long-standing, general facts. This article will not claim anything about how many people have been harmed or about any specific brand, because the sources behind the agenda coverage do not provide that, and a proposal is not the place to look for it either.
Reading Labels While the Rule Is Pending
Until anything changes, the burden of checking falls on the buyer and the professional. A product described as a keratin-style or smoothing treatment may or may not rely on these chemicals, and a label that sidesteps the word formaldehyde does not settle the question. The more reliable clue is a safety data sheet, which lists hazards and composition in more detail than a consumer label does. Ask for it before the service, not after.
Fragrance Allergen Labeling Under MoCRA
The second proposal is a different kind of rule, aimed at transparency rather than prohibition. MoCRA is the federal law that expanded FDA’s authority over cosmetics, and it includes provisions about identifying fragrance allergens on labels. The agenda entry says FDA intends to implement those provisions, including by identifying which substances must be disclosed as fragrance allergens when they appear in a cosmetic.
Why Scent Ingredients Stay Hidden
For decades, a single word such as “fragrance” or “parfum” has been allowed to stand in for a blend that may contain dozens of individual components. Manufacturers have traditionally treated scent formulas as trade secrets, so shoppers with a sensitivity could not tell which component was responsible for a reaction. A person who breaks out from a perfume might not be able to work out whether the trigger was in a body wash, a candle or a facial moisturizer.
Some labels already go further than the minimum. Some ingredient lists name individual scent components such as linalool and limonene, which are common aromatic compounds found in many essential oils and fragrance blends. Seeing them can be helpful for people who know they react to them, but they appear inconsistently, and the absence of a name on a given label is not proof that a component is missing.
What a Disclosure Rule Could Change
If FDA proposes and eventually adopts a rule, the practical effect would be a defined list of fragrance allergens that must be named when present, instead of hiding behind a single catch-all word. That would make it far easier for people with contact allergies to avoid their triggers, and it would give dermatologists a more reliable way to trace patterns in patients. It could also push manufacturers to reformulate products so as to avoid triggering a disclosure requirement.
Other regions have had allergen labeling systems for years, and the European Union is the most commonly cited example, so the concept is not new. Whether a US list would resemble those lists, or how long the list would be, cannot be determined from what has been reported. The rules there have changed over time, so anyone comparing systems should check current official sources instead of relying on a summary.
The Unknowns That Matter Most
Three questions will determine how much this rule matters in daily life. The first is which substances end up on the list, because the official allergen list has not been published. The second is whether concentration thresholds apply, meaning how much of a substance must be present before it has to be named. No thresholds have been published either. The third is the number of allergens, which the coverage does not state. Until a proposal appears with those answers, any claim about what your perfume bottle will say is guesswork.
From Proposal to Final Rule
Knowing the route a proposal takes makes the whole story less confusing. The path has a few clearly defined stages, and the first of them has not even happened yet.
The Proposal Stage
The agency publishes the draft rule in the Federal Register, the government’s daily record of notices and rules. The draft includes the proposed text, an explanation of why FDA believes the change is needed, and information about the expected costs and benefits. This is the stage the November 2026 target refers to.
The Public Comment Period
After publication, a public comment period follows. Anyone can submit comments: consumers, stylists, dermatologists, manufacturers, trade groups, and advocacy organizations. The length of this period for these two proposals has not been stated. Comments that contain specific data, such as reports of reactions or information about product reformulation costs, tend to be more useful to an agency than short expressions of support or opposition.
The Decision
After the comment period closes, FDA reviews what it received and decides whether to adopt the rule as proposed, change it, or withdraw it. Changes are common. A final rule normally specifies an effective date and sometimes a compliance date that gives manufacturers time to adjust labels and formulas. In this case no final rule exists, no labeling deadline has been set, and no compliance date can be guessed responsibly. Withdrawal is also possible, and recent history shows that it does happen.
A Realistic Picture of the Timeline
It helps to picture the sequence in calendar terms without attaching dates that nobody has announced. Suppose a proposal appears late this year or early next. A comment period would run for some weeks or months, followed by a stretch in which staff read and respond to what came in. Then the agency drafts the final text, which goes through its own review. Only after that does an effective date start the clock for businesses. Each step can be quick or slow, and a controversial topic tends to be slow. That is why the sensible planning assumption for both topics is that shelves will look the same for a good while.
Items Missing From the Agenda
The coverage of the new agenda also noted two things that are absent, and they help readers calibrate how much weight to put on agenda entries. Neither is a promise or a prediction, but both illustrate that the list can shrink as well as grow.
The first is an asbestos-testing rule for talc-containing cosmetics. The agenda no longer lists it, because FDA withdrew that rulemaking in late 2025. The second is the MoCRA good manufacturing practice rule. According to the coverage, that rule does not appear on the current agenda, which makes its timeline uncertain. Good manufacturing practice rules deal with how cosmetics are made, tested, and documented in a facility, and they are a significant part of how a safety law gets applied day to day.
The lesson is not that FDA is retreating from cosmetics regulation. The lesson is that an entry appearing on one edition of the agenda does not guarantee that a rule will arrive on schedule, in the form described, or at all. The two entries in this article have been listed with a November 2026 target, so they are on the current plan, but the same caution applies to them.
It also helps to keep the two proposals separate in your mind. The formaldehyde item is a prohibition on a specific class of salon and at-home products. The fragrance item is a disclosure requirement applying to a much wider range of cosmetics, from perfume to lotion to shampoo. They share an agenda and a target month, but they could proceed at different speeds, be amended differently, or end differently.
Known Facts and Open Questions at a Glance

One thing the table cannot show is the direction of travel. Both items are listed because FDA wants to move on them, and on the formaldehyde topic the agenda language is quite specific. Even so, a specific description in a planning document remains a description of intent.
Here is a simple example of why one list can behave differently from the other. A ban on a class of ingredients in a narrow product category affects a small number of formulas, and manufacturers can swap in alternatives. A labeling mandate touches nearly every scented item in a bathroom cabinet, requires new artwork and supplier data, and invites arguments about trade secrecy. The second type is often harder to finalize, even when its goal is easier for the public to grasp.
Practical Steps for Shoppers and Salon Clients
Nothing in the plan requires you to throw anything away or cancel an appointment. Still, there are sensible habits worth adopting now, none of which depend on the rules ever being finalized.
If You Get Smoothing or Straightening Treatments
Ask the stylist or salon for the product name and request the full ingredient list and the safety data sheet, which manufacturers are expected to provide. Look for words such as formaldehyde, methylene glycol, formalin and methanediol, and ask directly whether the formula releases formaldehyde when heated. Be cautious about a vague assurance such as “formaldehyde-free” without the paperwork behind it, since the proposal itself is concerned with chemicals that release formaldehyde rather than only the pure compound.
Pay attention to your body during and after a service. Strong fumes, stinging eyes, a burning nose or throat, and scalp irritation are all reasons to stop and get fresh air. A well-ventilated space matters, both for you and for the person doing the work, who may be exposed many times a day. Pregnant clients and people with asthma may want to talk to their own clinician before booking, since a professional can advise on personal circumstances in a way a news article cannot.
If You React to Scented Products
Start a simple log. Write down what you used, when, and what happened. A pattern across a week or two often reveals more than any single label. If reactions are frequent or severe, a dermatologist can perform patch testing, which identifies the actual substances your skin reacts to and gives you a personal list to compare against ingredient panels. That personal list will remain useful whatever the FDA does.
When you shop, read the whole ingredient panel, not just the front of the package. If you already know that linalool or limonene bothers you, check for them by name, and remember that a product that simply says “fragrance” may contain them without saying so. Fragrance-free products are a safer choice than products marketed as unscented, because the latter can contain masking scents.
If You Are Comparing Alternatives
Smoothing is not the only way to manage frizz or curl. Heat styling, blowouts, bonding or acid-based smoothing products, and simply changing a haircare routine all exist, and each carries its own trade-offs for hair health and cost. A stylist you trust should be able to explain the chemistry of whichever option they recommend without dodging questions. If the answers are evasive, treat that as information.
If You Work in the Beauty Industry
Salon owners, stylists, and small brands can use the waiting period productively. Review the formulas you use and the suppliers behind them, keep safety data sheets organized, and ask suppliers whether their smoothing products depend on formaldehyde releasers. Brands that make scented products might begin mapping which allergens their blends contain, so that a disclosure rule would not catch them off guard. Consider submitting comments when the proposal appears, because practical details from the people who make and apply products can shape a workable rule.
Conclusion
The sensible way to follow this story is to wait for evidence rather than rumor. The first thing to look for is the publication of the actual Notice of Proposed Rulemaking in the Federal Register. Only then will the open questions in the table above start to get answers: the length of the comment period, the scope of the formaldehyde prohibition, the list of fragrance allergens, and any thresholds.
Until then, three habits are enough. First, check the official FDA website and the Federal Register for primary documents rather than relying on social media posts, which tend to turn a proposal into a ban within a day. Second, remember that agenda dates can slip, so a quiet November would not be a sign that the idea has been dropped, and a loud November would not mean anything is final. Third, keep personal safety decisions independent of the rulemaking. If a treatment or product bothers you, you do not need a federal rule to stop using it.
For readers who want to take part, the comment period is the moment to act. Comments are most helpful when they are specific: describe what product you used, what happened, and what information on the label would have helped. A salon professional can explain how often a certain service is performed and what alternatives exist. A dermatologist can describe how allergen disclosure would change diagnosis. None of that requires technical expertise, only clarity.
Finally, keep expectations realistic. Even in a favorable case, a final rule would come after the comment period, after FDA reviews what it received, and with a compliance date that gives industry time to adapt. That points to a long timeline, measured in months or years rather than weeks. For now, the right posture is informed patience: read labels, ask questions, and wait for the real text.

Frequently Asked Questions
1. Is the FDA Banning Formaldehyde in Hair Straighteners Right Now?
No. According to the regulatory agenda summaries, the FDA plans to issue a proposed rule in November 2026 that would prohibit formaldehyde and formaldehyde-releasing chemicals in heated hair smoothing and straightening products. A proposal is not binding, and nothing has to change in salons or on shelves yet.
2. When Will the New Fragrance Allergen Labels Appear on Cosmetics?
No date has been set. The agenda lists a proposed rule for November 2026, but a public comment period, an FDA decision and a final rule would all have to follow. No labeling deadline exists at this point.
3. Why Is Methylene Glycol in Hair Products a Concern?
It is a form of formaldehyde dissolved in water, and it can release formaldehyde gas when heated, for instance, by a flat iron. That is why the agenda names it as an example of a formaldehyde-releasing chemical to be covered by the proposed prohibition.
4. How Do I Know if a Fragrance Allergen Is in My Lotion or Shampoo?
Today, you often cannot tell, because a single word such as “fragrance” may cover many components. Some labels name specific compounds such as linalool and limonene, so check the full ingredient panel and consider asking a dermatologist about patch testing.
5. Can I Comment on an FDA Proposed Rule?
Yes. Once a proposal is published, a public comment period opens, and anyone can submit comments. The length of the period for these two proposals has not been stated, so check the official notice when it appears.
6. What Happened to the Talc Asbestos-Testing Rule for Cosmetics?
The current agenda no longer lists it, because FDA withdrew that rulemaking in late 2025. The good manufacturing practice rule under MoCRA also does not appear on the current agenda, so its timeline is uncertain.
