Is Berina Hair Dye tested to prevent reactions in people with asthma or respiratory hypersensitivity?

Using hair dyes is a common practice for millions of people who want to change their look, cover gray hair, or simply express their personality. However, for individuals suffering from asthma or respiratory hypersensitivity, the application of chemicals, especially those releasing vapors or fine particles, can raise legitimate concerns. The question of the safety of Berina Dark Brown Violet Hair Dye A14 , available on Siam Marketplace , is therefore particularly relevant for this group of consumers.

This article aims to take an in-depth look at the composition of this specific product, analyze the potential risks associated with its components for the respiratory tract, and determine whether specific tests have been conducted to ensure its safety for people with asthma or hypersensitivity. We will also discuss general precautions to take when using any hair dye, with an emphasis on the needs of people with respiratory sensitivities.

Understanding Asthma and Respiratory Hypersensitivity

Before analyzing the product itself, it is crucial to understand what asthma and respiratory hypersensitivity are and why certain chemicals can trigger reactions.

What is Asthma?

Asthma is a chronic inflammatory disease of the airways, characterized by bronchial hyperreactivity. This means that the bronchi (the tubes that carry air to the lungs) of people with asthma are particularly sensitive to various stimuli, called triggers. When exposed to a trigger, the walls of the bronchi become inflamed, swollen, producing excess mucus, and the muscles surrounding them contract (bronchospasm). This narrowing of the airways makes breathing difficult, causing symptoms such as:

• Shortness of breath (dyspnea)
• Wheezing
• Cough, often dry and irritating, sometimes nocturnal
• Feeling of oppression or tightness in the chest

Asthma triggers vary from person to person but can include allergens (dust mites, pollen, mold, pet dander), irritants (tobacco smoke, air pollution, strong odors, volatile chemicals), respiratory infections (colds, flu), exercise, cold, dry air, or emotional stress.

What is Respiratory Hypersensitivity?

Respiratory hypersensitivity is a broader term that encompasses an increased reactivity of the airways to various environmental stimuli, without essentially corresponding to a diagnosis of classic asthma. This can manifest as asthma-like symptoms (cough, chest tightness, throat irritation) or as rhinitis-like reactions (runny nose, sneezing, nasal congestion) or sinusitis upon exposure to irritants. Individuals with allergic rhinitis, chronic sinusitis, or simply increased sensitivity to strong odors and chemicals may be considered to have respiratory hypersensitivity. The mechanisms may involve inflammation, direct irritation of the mucous membranes, or an exaggerated nervous reaction.

Why can Berina Hair Dyes be a problem?

Hair dyes, especially permanent oxidation dyes like Berina A14, contain several chemicals that can cause problems for sensitive individuals:

• Volatile Organic Compounds (VOCs): Many ingredients, as well as chemical reactions themselves, release VOCs into the air during mixing and application. Inhaling these vapors can irritate the respiratory tract and trigger symptoms in people with asthma or hypersensitivity. Ammonia (ammonium hydroxide) is a notable example, known for its strong, pungent odor.
• Fine Particles: Although less documented than VOCs, the process can also release fine particles or aerosols, which are potentially irritating.
• Fragrances: Added fragrances, while intended to mask chemical odors, can themselves be triggers for some sensitive or asthmatic individuals.
• Potential Allergens: Compounds such as p-Phenylenediamine (PPD) are known to be potent skin allergens, but in rare cases, systemic or respiratory reactions could theoretically occur in highly sensitized individuals, although inhalation irritation is the primary risk.

Analysis of Berina Hair Dye Components and Potential Risks

Now let's look at the key ingredients listed for Dark Brown Violet Dye A14 and their relevance to respiratory sensitivity.

Key Ingredients and Their Functions/Potential Respiratory Risks:

• Ammonium Hydroxide (Ammonia):
  • Function: Alkaline agent. Opens the hair cuticles to allow dyes and peroxide to penetrate.
  • Respiratory Hazard: This is one of the main culprits for the strong, pungent odors associated with hair dyes. Ammonia is a known respiratory irritant. Inhaling its vapors can cause coughing, throat and nose irritation, watery eyes, and possibly trigger an asthma attack or shortness of breath in sensitive individuals. Concentration and room ventilation are critical factors.
• p-phenylenediamine (PPD):
  • Function: Essential dye precursor for dark, permanent hair colors. Reacts with hydrogen peroxide to form large color molecules trapped in the hair.
  • Respiratory Risk: PPD is primarily known as a potent contact allergen, causing allergic dermatitis. Direct respiratory risks from inhaling PPD in powder form (rare in cream/liquid dyes) or vapors are less common but documented in exposed workers (hairdressers), potentially causing occupational asthma. For the occasional user, the main risk remains irritation from the overall vapors of the mixture, but extreme sensitization is never completely excluded.
• Resorcinol (Resorcin):
  • Function: Color coupler. React with precursors (such as PPD) and peroxide to modify and stabilize the final shade.
  • Respiratory Hazard: Like PPD, resorcinol is a potential skin irritant and sensitizer. It may also contribute to the overall irritating vapors of the mixture, although less volatile than ammonia. Occupational exposure studies indicate a potential for respiratory irritation.
• Hydrogen Peroxide (Hydrogen Peroxide):
  • Function: Oxidizing agent (in the activator cream). Lightens the hair's natural melanin and activates color precursors (PPD, resorcinol).
  • Respiratory Risk: Hydrogen peroxide solution can release oxygen and produce mildly irritating vapors, especially in high concentrations (9% or 30 volumes is quite potent). It contributes to the overall chemical reaction that can generate vapors. Direct contact with mucous membranes is irritating.
• Sodium sulfite:
  • Function: Antioxidant. Helps stabilize the formula and prevent premature oxidation of colorants in the tube.
  • Respiratory Risk: Sulfites are known triggers of asthma attacks in some asthmatics, particularly when ingested (in food and beverages). The risk of inhaling hair dye is less clear but not negligible. They can release sulfur dioxide (SO2), an irritant gas, in acidic environments or during certain reactions. The amount present in the dye is probably low, but caution is advised for asthmatics sensitive to sulfites.
• Perfume (Fragrance):
  • Function: Mask chemical odors from other ingredients.
  • Respiratory Risk: Perfume blends often contain many volatile compounds that are common respiratory irritants and asthma triggers for sensitive individuals. The exact identity of perfume components is generally not disclosed ("trade secret").
• Other Ingredients: Alcohols (stearyl, cetyl) and oleic acid are thickening, softening, and emulsifying agents, generally favored as low volatility and unlikely to cause major respiratory problems if inhaled, although they contribute to the texture of the product. Deionized water is the base. Tetrasodium EDTA is a chelating (stabilizing) agent. 8-Hydroxyquinoline sulfate is a stabilizer for the peroxide.

The Crucial Question: Specific Tests for Asthma/Hypersensitivity?

This is the crux of the matter. To date, it is highly unlikely that Berina Dark Brown Violet A14, or the vast majority of consumer hair dyes, has undergone specific clinical testing designed to assess its safety in people with asthma or respiratory hypersensitivity.

Standard safety testing for cosmetics typically focuses on:

• Skin irritation and corrosion (skin tests).
• Eye irritation.
• Skin sensitization (contact allergy).
• Acute oral or cutaneous route.
• Mutagenicity/genotoxicity (DNA damaging potential).

Specific inhalation tests assessing the asthma trigger potential of cosmetic products such as hair dyes are generally not part of standard regulatory test batteries for consumer products. Such tests would be complex and expensive to conduct, and reactions can be highly individual.

Therefore, it cannot be claimed that this product has been "tested for non-reactions" in asthmatic or hypersensitive individuals. The lack of specific mention of such testing on the packaging or in the manufacturer's information reinforces this conclusion. Safety for these groups therefore relies on a risk assessment based on known ingredients and the application of strict precautions for use.

Recommendations and Precautions for Sensitive People

Given the likely lack of specific testing and the presence of irritating ingredients (ammonia, perfume, PPD, resorcinol, sulfites), people with asthma or respiratory hypersensitivity should approach the use of Berina A14 tincture (and any similar tincture) with extreme caution. Here are the key recommendations:

1. Prior Consultation Essential

• Doctor/Allergist: Discuss your intention to use hair dye with your primary care physician or allergist. They are familiar with your medical condition, the severity of your asthma or sensitivity, and any allergies you may have. They can advise you on the level of risk, recommend specific allergy tests if necessary (such as a PPD patch test), and ensure your background asthma medication is optimal.
• Professional Hairstylist (if applicable): If you prefer to color in a salon, be sure to inform your hairstylist of your respiratory condition. A good professional should be aware of the risks, work in a well-ventilated space, and generally use techniques to minimize your exposure to fumes (e.g., faster application, directed ventilation). Some salons also use specific product lines that may be less irritating (but caution is still required).

2. The Patch Test: More Crucial Than Ever

Although the patch test is primarily intended to detect skin allergies (such as PPD), it is absolutely non-negotiable before each use, even if you have used the product before.

• How to do it: Mix a small amount of the coloring cream and the activating cream as directed in the package insert. Apply a small amount of the mixture behind your ear or in the crease of your elbow. Let it dry and do not wash the area for 48 hours.
• What to watch for: During these 48 hours, carefully monitor the tested area for any skin reactions (redness, itching, swelling, blisters).
• Respiratory Significance: Although it does not directly test for respiratory response, a positive skin reaction indicates sensitivity to one or more components. A person reacting via the skin route is potentially at greater risk of also reacting via other routes, including respiratory irritation. If the cut test is positive, DO NOT USE THE PRODUCT.

3. Maximum Ventilation: The Key to Reducing Exposure

This is arguably the most important precaution to minimize respiratory irritation.

• Choose the right location: Apply the stain in the best-ventilated room in your home, ideally a bathroom with an open window and/or an extractor fan (VMC). Avoid small, confined spaces with no ventilation.
• Open the windows wide: Create a draft if possible by opening a window and a door, or two windows opposite each other.
• Use a fan: Position a fan so that it directs the vapors away from your face (not toward anyone else). Do not point it directly at colored hair as this may affect the coloring process.
• Run the extractor fan: If your bathroom has one, turn it on before, during, and for at least 30 minutes after application and the setting time.
• Avoid peak pollution hours: If you live in a polluted area, avoid ventilating during outdoor pollution shots.

4. Minimize Exposure Time and Direct Inhalation

• Prepare everything in advance: Have all the equipment ready (gloves, non-metallic bowl, brush, old towel, timer) to reduce the time spent handling opened products.
• Mix just before use: Only prepare the mixture when you are ready to apply it.
• Apply quickly and efficiently: Try to be as quick as possible when applying to limit the time the products release fumes.
• Avoid breathing over the bowl: When mixing or scooping the product, keep your face away.
• Leave the room during the application time: If possible, once the application is complete, leave the well-ventilated room and go to another room not contaminated by vapors for the recommended application time (keeping an eye on the time). Return only to rinse.
• Wearing a mask? Wearing a simple surgical or fabric mask offers very limited protection against chemical gases and vapors such as ammonia. A mask with activated carbon filters (type FFP2 or FFP3 with a valve and carbon layer, or a reusable half-mask with suitable cartridges) could offer better protection, but its effectiveness depends on the fit and the type of filter. Its use can be restrictive and should be discussed with a doctor, as wearing a mask can also hinder breathing in some asthmatics. Ventilation remains the priority measure.

5. Have your emergency treatment on hand

If you have asthma, make sure you have your rescue bronchodilator (blue inhaler such as Ventolin®, Salbutamol, etc.) immediately available before, during, and after dyeing. Recognize the signs of worsening symptoms (cough, wheezing, chest tightness, shortness of breath) and do not hesitate to use your medication and stop the dyeing process immediately if necessary. If symptoms are severe or do not improve quickly, seek emergency medical attention.

6. Consider Alternatives?

If the risks seem too great or if you have already reacted badly in the past, explore potentially less irritating alternatives:

• Ammonia-free dyes: These often use other alkaline agents (such as monoethanolamine - MEA) which may be less volatile and have a less strong odor, but can still be irritating to some. They still contain dyes (often PPD or derivatives) and peroxide.
• Semi-permanent or temporary dyes: These generally contain neither ammonia nor peroxide and are applied to the cuticle without penetrating deeply. They are less aggressive but last less long and cover gray hair less well. Always check the ingredients for dyes and fragrances.
• Plant-based dyes (Henna, Indigo): Pure plant powders (beware of blends containing metallic salts or added natural PPD!) are an option. However, some people may also be allergic to plants, and the plant-based scent may be unpleasant or irritating to some. The color result is less visible and the range of shades is more limited.
• Professional Specific Services: Some salons offer techniques like highlights or balayage where the product touches less of the scalp and is applied further away from the airways, which can reduce exposure.

Focus on Berina Dark Brown Violet Dye A14

Beyond the respiratory safety aspects, Berina A14 dye aims to achieve a specific shade: a dark brown with purple highlights. It's a trendy and deep color.

Features and Intended Use

• Type: Permanent oxidation coloring.
• Target Color: Dark Brown Purple. The final result will always depend on your natural base color or the artificial color already present in your hair.
• Kit Contents (typical): One tube of coloring cream (60ml) and one bottle of 9% activator cream (60ml). Read the instructions carefully for the exact contents.
• Directions: Designed for home application, carefully following the provided instructions. These generally involve mixing the contents of the two components in a non-metallic bowl, applying the mixture to dry, unwashed hair (unless otherwise specified), leaving on for a set time (often 20-40 minutes), then rinsing thoroughly and applying a post-color treatment (sometimes included, sometimes not).
• Lift Level: The 9% activator (30 volumes) allows a certain level of lift (approximately 2-3 tones), necessary for the color pigments to reveal themselves, especially on a dark base.

It is essential to follow the specific instructions provided with the Berina A14 product to achieve the best color results and ensure correct application. Never forget the gloves provided or purchased separately to protect your hands.
