Detailed composition of Selsun 2.5% shampoo
The formulation of Selsun 2.5% has been specially designed to target the root causes of dandruff and seborrheic dermatitis. Here are its main components:
Main active ingredient
Selenium sulfide (2.5% w/v): This is the key compound that gives the shampoo its therapeutic properties. Selenium sulfide works on several levels:
- Reduction of excessive production of dead skin cells
- Control of the proliferation of the fungus Malassezia, often involved in dandruff
- Antifungal and anti-inflammatory action on the scalp
Other notable ingredients
The formula also contains complementary agents that optimize its action:
- Monoethanolamine Lauryl Sulfate: A surfactant that provides abundant lather for deep cleansing of the scalp.
- Empigen BB: Strengthens the cleansing action and helps eliminate excess sebum.
- Bentonite: Gives the product its ideal texture and improves its application.
- Glyceryl Monoricinoleate S: Promotes the cohesion of the different components.
- Sodium Chloride: Adjusts viscosity for optimal use.
How selenium sulfide works against dandruff
The mechanism of action of Selsun 2.5% shampoo is complex and multifactorial:
1. Targeted antifungal action
Selenium sulfide specifically inhibits the growth of the fungus Malassezia, a microorganism naturally present on the scalp but which, if excessively proliferated, causes irritation and flaking.
2. Regulation of cell renewal
It normalizes the process of desquamation of the epidermis, thus reducing the formation of visible scales (dandruff).
3. Anti-inflammatory effect
By calming irritations, it reduces itching and redness associated with seborrheic dermatitis.
4. Reduction in sebum production
It helps regulate the activity of the sebaceous glands, creating an environment less favorable to the development of dandruff.
Clinically proven effectiveness
Several scientific studies have evaluated the effectiveness of selenium sulfide in the treatment of dandruff and seborrheic dermatitis:
- A study published in the Journal of the American Academy of Dermatology showed a 70-80% reduction in dandruff after 4 weeks of use.
- In cases of moderate seborrheic dermatitis, the improvement rate reaches 65% according to research from the British Journal of Dermatology.
- Compared to other anti-dandruff agents such as zinc pyrithione, selenium sulfide shows superior efficacy on severe forms.
Recommended usage protocol
For optimal results with Selsun 2.5% , follow these steps:
- Wet your hair and scalp thoroughly
- Apply a sufficient amount of shampoo (approximately 5 ml)
- Massage gently to distribute the product evenly over the entire scalp
- Leave on for 2 to 3 minutes to allow the active ingredient to penetrate
- Rinse thoroughly with lukewarm water
- Repeat the operation 2 times a week for 4 weeks
- For maintenance, use once a week or as recommended by your dermatologist.
Precautions for use and potential side effects
Like any active treatment, Selsun 2.5% requires certain precautions:
Possible side effects
- Temporary dryness of the scalp
- Mild irritation in sensitive skin
- Temporary change in color of bleached hair (minimal risk)
Contraindications
- Known hypersensitivity to selenium sulfide
- Large skin lesions or open wounds on the scalp
- Pregnant or breastfeeding women (on medical advice only)
Expert opinions and dermatological recommendations
Dr. Martin Lefèvre, a dermatologist in Paris, explains: "2.5% selenium sulfide remains one of the gold standard treatments for stubborn dandruff and mild to moderate forms of seborrheic dermatitis of the scalp. Its direct antifungal action and its effect on cell renewal make it a complete solution."
However, it recommends:
- Do not use more than twice a week as an attack treatment.
- Alternate with a mild shampoo to avoid dryness
- Consult if no improvement is visible after 4 weeks
