When you suffer from sensitive skin conditions like rosacea, eczema, dermatitis, or acne we tend to only focus on the products we use on our face.
What is just as important is being aware of what haircare products you use. Haircare products can have a significant impact on sensitive skin, as many of them contain ingredients that may further irritate your condition or cause allergic reactions.
The most common ingredient offenders include:
- Fragrances: Many haircare products contain artificial or synthetic fragrances that can cause irritation, allergic reactions, or dryness. Even "fragrance-free" products can still contain masking agents that might trigger a reaction.
- Sulphates: Ingredients like sodium lauryl sulphate (SLS) or sodium laureth sulphate (SLES) are often used to create lather. They can be harsh, stripping the skin of natural oils, leading to dryness and irritation.
- Preservatives: Preservatives like parabens (e.g., methylparaben, ethyl paraben) can cause skin sensitivity, triggering allergic reactions.
- Alcohols: Certain alcohols, like isopropyl alcohol, can be drying and irritating to sensitive skin, causing discomfort and redness.
- Silicones: Ingredients like dimethicone can build up on the scalp, potentially causing clogged pores, irritation, or acne.
- Essential Oils: Though natural, some essential oils like tea tree oil, peppermint oil, or lavender oil can be irritating to sensitive skin or cause allergic reactions, especially when used in high concentrations.
- Colorants: Artificial dyes added to products for aesthetic purposes might also cause allergic reactions or irritation.
How Haircare Affects Eczema
The scalp and other areas of the body affected by eczema are more vulnerable to irritation, and certain haircare ingredients or practices can trigger flare-ups. Here is how haircare can affect eczema:
Harsh Ingredients
- Sulphates: These surfactants can strip the skin of its natural oils, leading to dryness and exacerbating eczema symptoms.
- Parabens: These can cause allergic reactions or irritation in people with eczema.
- Fragrances: Synthetic fragrances often used in shampoos and conditioners can be a major trigger for eczema flare-ups, leading to redness, itching, and irritation.
- Alcohols: Some alcohols in hair products (like isopropyl alcohol) can be drying and worsen eczema symptoms by stripping moisture from the skin.
Drying the Scalp
Eczema often causes the skin to become dry and inflamed. Haircare products that are too harsh, or washing the hair too frequently, can further dry out the scalp, leading to more irritation and flaking. This can create a vicious cycle of dry skin, itching, and discomfort.
pH Imbalance
The skin, including the scalp, has a natural pH that should be maintained for optimal health. Haircare products with an incorrect pH (either too acidic or too alkaline) can disrupt this balance, making the skin more vulnerable to irritation and eczema outbreaks.
How Haircare Affects Dermatitis
Both contact dermatitis and seborrheic dermatitis, a condition characterised by inflamed, irritated, and itchy skin can be affected by haircare products.
Contact Dermatitis
- Irritants in Haircare Products: Many shampoos, conditioners, and styling products contain irritants like sulphates, alcohol, fragrances, and preservatives. These ingredients can trigger or worsen irritant contact dermatitis, especially for people with sensitive skin. Prolonged exposure to these ingredients can lead to flare-ups on the scalp, neck, or forehead.
- Allergic Reactions: Some fragrances, preservatives, or even plant-based ingredients, can cause allergic contact dermatitis. This results in itching, redness, and swelling where the product was applied. If you have a known allergy, using a product with those ingredients can make symptoms worse.
Seborrheic Dermatitis
- Excess Oil and Overuse of Products: Many haircare products, particularly conditioners, styling gels, and serums, contain heavy oils or moisturising agents that can exacerbate seborrheic dermatitis by increasing oil build-up on the scalp. This can contribute to clogged hair follicles, trapped oils, more scaling and flaking, which can make the condition more visible or uncomfortable.
- Harsh Ingredients: Products containing harsh chemicals or fragrances can irritate seborrheic dermatitis. For example, sulphates can strip the scalp of its natural oils, which may cause the skin to compensate by producing even more oil, potentially worsening seborrheic dermatitis symptoms.
- Drying of the Scalp and Scalp Sensitivity: Some haircare products can strip the skin of its natural oils, leading to dryness. This loss of moisture can worsen irritation, itching, and flaking. A dry scalp can also lead to more inflammation, particularly in the context of seborrheic dermatitis or eczema.
Both irritant and allergic contact dermatitis can make the scalp more sensitive. The combination of sensitive skin and harsh haircare products can trigger discomfort, including burning, itching, or redness.
How Haircare Affects Acne
Haircare products can significantly affect acne, especially when they come into contact with the areas prone to breakouts including the face, forehead or back.
Comedogenic Ingredients
- Oils: Heavy oils like coconut oil, argan oil, or certain silicones used in hair products (such as conditioners and styling gels) can transfer to the skin when the hair touches the face, leading to clogged pores and acne breakouts (for those with acne-prone skin)
- Silicones: Some hair products contain silicones (like dimethicone) that can coat the hair and skin, creating a barrier that can trap dirt, oil, and bacteria on the skin, leading to acne breakouts.
Fragrances and Strong Chemicals
- Fragrances: Artificial fragrances in shampoos, conditioners, and styling products can irritate the skin, trigger allergic reactions, which can worsen acne or cause new breakouts.
-
Sulphates and Alcohols: Ingredients like sulphates and certain alcohols can be drying and irritating, stripping the skin of its natural moisture and potentially triggering an increase in oil production. This excess oil can clog pores, contributing to acne.
Scalp Acne (Folliculitis) and Hairline Acne
Acne is not limited to just the face; it can also appear on the scalp or around the hairline.
- Excess Product Build-Up: If hair products are not properly washed out, they can lead to build-up, causing irritation, clogged pores, and folliculitis on the scalp, or acne breakouts along the hairline.
- Sweat and Oil: People who use a lot of styling products or have oily hair may experience more scalp or hairline acne, especially when combined with sweating from physical activity. Sweat mixed with hair products can lead to clogged pores and acne flare-ups on the scalp and hairline.
How Haircare Affects Rosacea
Haircare products can have an impact on rosacea, as certain haircare products and practices can exacerbate flare-ups or contribute to irritation. Here is how haircare can affect rosacea.
Strong Ingredients
- Fragrances: Synthetic fragrances, which are commonly added to shampoos, conditioners, and styling products, can be a major trigger for rosacea. Fragrance can irritate the skin, causing redness, itching, or inflammation.
- Sulphates: Sodium lauryl sulphate and other harsh surfactants are often used in shampoos to help them lather. These ingredients can be drying and irritating to sensitive skin, leading to increased rosacea flare-ups.
- Alcohol: Some haircare products, particularly hair sprays, gels, and styling mousses, contain alcohols that can be drying and irritating to the skin. Alcohol can strip moisture from the skin and worsen rosacea symptoms, leading to increased dryness, redness, and irritation.
Hot Water and Heat
Heat is a well-known trigger for rosacea flare-ups. Haircare routines that involve hot water or heat styling can contribute to irritation and redness.
- Hot Water: Washing your hair with very hot water can dilate blood vessels and trigger rosacea flare-ups, leading to more redness and inflammation on the face and scalp.
- Heat Styling Tools: Blow dryers, curling irons, and straighteners generate heat that can exacerbate rosacea. The heat can increase blood flow to the skin, causing flushing and redness, which may worsen rosacea symptoms.
Scalp Sensitivity
Haircare products that are not suitable for sensitive skin can irritate the scalp, leading to inflammation, itching, or even seborrheic dermatitis (a condition that may overlap with rosacea).
- Product Build-Up: When hair products like conditioners or styling gels build up on the scalp, they can cause irritation. If these products come into contact with the face, they can also worsen rosacea symptoms.
- Increased Oil Production: Some haircare products designed for moisturising can leave a residue or excess oil, which can clog pores or irritate the skin, potentially leading to flare-ups in individuals with rosacea.
Haircare Tips for Managing Your Sensitive Skin
If you suffer from a sensitive skin condition, keep your haircare routine as simple and gentle as possible. Stick to products designed for sensitive skin, avoid known irritants, and prioritise ingredients that soothe and hydrate.
Being mindful of the ingredients and products you use, and taking care to protect the skin, you can help manage your sensitive skin while maintaining a healthy scalp and hair.
- Use Gentle and Fragrance-Free: Choose sulphate-free, fragrance-free, and hypoallergenic shampoos and conditioners that are formulated for sensitive skin.
- Moisturise: Look for hair products that contain moisturising ingredients like aloe vera, glycerine, or oat extracts, which can help soothe the scalp and prevent dryness.
- Avoid Over-Washing: Wash hair less frequently to prevent stripping the scalp of natural oils. When washing, use lukewarm water.
- Rinse Thoroughly: Always rinse out conditioners and styling products thoroughly to prevent any build-up or residue that could irritate the skin or scalp.
- Non-Acidic, Non-Irritating Styling Products: Choose styling products that are alcohol-free and sulphate-free, as these tend to be gentler on sensitive skin.
- Non-Comedogenic Products (Acne prone-skin): Look for haircare products labelled non-comedogenic or oil-free.
- Avoid Heavy Oils and Silicones: If you have acne-prone skin, avoid hair products containing heavy oils or silicones.
- Avoid Touching Your Hair: Try to keep your hair off your face as much as possible to avoid transferring oils or product residues to your skin.
- Patch Test New Products: Always patch-test new haircare products on a small area of skin to ensure they do not cause a reaction.
- Limit Heat Styling: Try to avoid excessive use of heat styling tools to prevent further dryness or irritation on the scalp.
- Avoid Scratching: If your scalp becomes itchy or irritated, avoid scratching, as this can worsen irritation and potentially cause infection.
- Scalp Massages: Gentle scalp massages can help increase circulation and maintain a healthy scalp without causing irritation.
- Be Cautious with Hair Dyes: If you dye your hair, be aware that certain hair dyes, especially those with ammonia or peroxide, can cause irritation on sensitive skin.
