Oily Hair: Causes and Effective Solutions
Understanding Oily Hair
Oily hair is a common problem affecting many. To effectively address it, understanding the underlying causes is crucial. These causes range from simple mistakes in hair care routines to more serious internal health issues. This article will explain what causes oily hair and provide effective solutions to manage it.
Recognising the Signs of Oily Hair
Oily hair is characterised by hair looking limp and greasy just a few hours after washing. Even after a morning wash, the hair may appear limp and clumped together by evening. For those with excessively oily hair, daily washing may not be enough, leading to frustration and a feeling of uncleanliness.
Causes of Oily Hair
Oily hair is actually a problem with an oily scalp. Overactive sebaceous glands on the scalp produce excess sebum (oil). This sebum accumulates on the scalp and transfers to the hair through combing or touching.
Several factors can contribute to overactive sebaceous glands, including:
- Hormonal imbalances: Excessive production of hormones such as androgens, progesterone, and prolactin.
- Genetics: A hereditary predisposition to excessive sebum production.
- Nutritional deficiencies: Poor diet or medication side effects leading to vitamin and mineral deficiencies.
- Stress: Particularly long-term stress.
- Hair care mistakes: Using unsuitable products or improper hair washing techniques.
- Skin conditions: Such as seborrheic dermatitis.
- Internal illnesses: Such as hyperthyroidism or diabetes.
Common Hair Care Mistakes
The following hair care mistakes can accelerate oil buildup:
- Washing hair only once: Washing hair twice is recommended to thoroughly cleanse the scalp and remove buildup.
- Insufficient rinsing: Residue shampoo can leave hair looking greasy and may cause irritation and dandruff.
- Using harsh shampoos: Shampoos with aggressive detergents can damage the scalp's protective barrier and disrupt sebum production.
- Sleeping with wet hair: Moisture on the scalp combined with warmth creates a breeding ground for bacteria and fungi.
- Washing hair too frequently or infrequently: Over-washing can trigger increased sebum production, while infrequent washing disrupts the scalp's microbiome.
Seborrheic Dermatitis and Oily Hair
Excessive oiliness can be a sign of seborrheic dermatitis (SD), a chronic and bothersome skin condition. If excess sebum appears as yellowish scales accompanied by itching and redness, consult a dermatologist or trichologist, as you may have SD.
Seborrheic dermatitis results from the overproduction of abnormally composed sebum. Malassezia yeast feeds on this sebum, multiplying rapidly and causing inflammation, discomfort, and deterioration of the scalp and hair condition.
Combating Oily Hair: A Holistic Approach
To effectively reduce oily hair, a holistic approach is recommended. This increases the chances of addressing the root cause. Analyse your hair products, ensure proper hair care habits, and review your diet.
Hair Care for Oily Hair
Frequent washing is common for oily hair, but let's look at your products first. Switch to products better suited to your scalp. A gentle shampoo without harsh detergents is ideal for daily use. Oily scalp can be a reaction to over-stripping, or a sign of irritation. Use only mild products that strengthen the scalp's hydrolipidic film and care for its microbiome – says Karina Pietrzela, cosmetologist at Clinica Cosmetologica.
Opt for hair products with light, preferably natural, active ingredients. Plant extracts like rosemary, calendula, and centella asiatica moisturise and normalise sebum production. Betaine, panthenol, and allantoin moisturise and soothe the scalp, preventing irritation. Black seed oil repairs the hydrolipidic film, reduces itching and scaling, minimises hair loss, and stimulates hair growth.
Use a scalp scrub at least once a week to remove dead skin cells and excess sebum, dissolving sebum in hair follicles. Acidic peels are particularly recommended, as they don't damage hair shafts and restore the scalp's pH, benefiting the skin's microbiome. Peels lift hair from the roots, keeping your style looking fresher for longer.
For SD, where oily scales accumulate, removal may be more challenging. Exfoliation should be more frequent, even every other day, using dedicated products. Simultaneously, moisturise and soothe the scalp and use anti-fungal shampoos.
Good Hair Care Habits
Beyond products, review your hair care habits. Ensure thorough washing (twice) and use lukewarm water, as hot or cold water can stimulate sebum production. Air drying is best, avoiding towels or turbans, which create a sauna effect. If air drying takes too long, use a hairdryer on a cool setting rather than sleeping with wet hair.
Maintain hygiene for hair tools and frequently change pillowcases. Brushes and combs accumulate sebum and dead skin, becoming breeding grounds for microorganisms. Clean them regularly – at least once a week. Change pillowcases with the same frequency.
Diet and Oily Hair
Poor nutrition can contribute to oily hair. A diet high in processed foods, sweets, fats, and alcohol will worsen sebum production. Avoid spicy foods.
Base your diet on unprocessed foods – vegetables, fruits, nuts, eggs, meat, cereals, and dairy. Prioritise B vitamins (legumes, nuts, eggs, dairy, fish, cereals). Include zinc-rich foods like pumpkin seeds, sunflower seeds, eggs, and hard cheeses. If medication causes vitamin and mineral deficiencies, consult your doctor about supplementation.
Consider herbal infusions known to regulate sebum production, such as nettle leaf, calendula flower, yarrow herb, or lavender flower. Consult your doctor before using herbs if you are on medication.
Summary
Many factors contribute to oily hair. If the problem persists despite changes in hair care, and is accompanied by itching, redness, and scaling, consult a dermatologist or trichologist. You may have seborrheic dermatitis, requiring specialist treatment and care.
