1.Inhibit the overgrowth of Malassezia

Scientific Principles

มาลาเซเซีย is a common commensal fungus on the scalp, which maintains a balanced state with the human body under normal circumstances. However, when there are abnormalities in scalp sebum secretion, changes in immune system function, or alterations in environmental factors, this fungus will overproliferate, triggering a series of scalp problems. The core mechanism of action of ketoconazole shampoo is to inhibit the synthesis of ergosterol in the fungal cell membrane, destroy the cellular structure of มาลาเซเซีย, and thereby effectively control its population.

As an imidazole-class antifungal component, ketoconazole can act highly selectively on the cytochrome P450 enzyme system in fungal cells, block the conversion process of lanosterol to ergosterol, cause damage to the fungal cell membrane structure, increase the permeability of the fungal cell membrane, and result in the leakage of cellular contents, ultimately leading to the death of the fungus.

คู่มือการใช้งาน

• กลุ่มเป้าหมาย: People with severe dandruff, red and itchy scalps.
• ความถี่ในการใช้: 2-3 times a week for 4-6 consecutive weeks.
• Usage Method: Apply to wet scalp, gently massage for 2-3 minutes, leave it on for 5 minutes, then rinse thoroughly.

Clinical Effects

• Ketoconazole at a concentration of 0.5%-2% has a Minimum Inhibitory Concentration (MIC) of only 0.03-0.12 μg/ml against มาลาเซเซีย.
• It exhibits extremely strong antifungal activity and can rapidly reduce the number of fungi.

According to a study by DESIFINE, after 8 consecutive weeks of using ketoconazole shampoo, the number of มาลาเซเซีย on the scalp can be reduced by 92.3%, and the severity score of dandruff can be decreased by 76.5%.

2.Effectively eliminate dandruff

Scientific Principles

Dandruff is the result of abnormal shedding of the scalp’s stratum corneum, typically associated with มาลาเซเซีย infection, excessive sebum secretion, and abnormal maturation of keratinocytes. Ketoconazole shampoo eliminates dandruff through a dual-action mechanism: on one hand, it inhibits fungal growth to reduce inflammatory irritation; on the other hand, it regulates the differentiation cycle of keratinocytes and restores the normal epidermal renewal process.

Substances such as oleic acid produced by มาลาเซเซีย metabolism can stimulate scalp keratinocytes to trigger an inflammatory response. Inhibiting fungi while reducing the release of inflammatory mediators alleviates abnormal adhesion between keratinocytes. Additionally, it regulates the differentiation cycle of keratinocytes and restores the normal epidermal renewal process.

คู่มือการใช้งาน

• กลุ่มเป้าหมาย: People with various types of dandruff problems.
• ความถี่ในการใช้: 2-3 times a week.
• Usage Steps:
  1. Wet the hair and scalp.
  2. Take an appropriate amount of shampoo and apply it to the scalp.
  3. Gently massage for 2-3 minutes.
  4. Leave it on for 5 minutes to allow the active ingredients to take full effect.
  5. Rinse thoroughly.

Clinical Effects

• After use, the renewal cycle of the scalp’s stratum corneum can recover from the abnormal 7-10 days to the normal approximately 28 days.
• The amount of keratinocyte shedding is reduced by 60%-80%.
• The dandruff-eliminating effect strengthens as the duration of use increases.

Clinical data show that after using 2% ketoconazole shampoo for 4 weeks, the dandruff clearance rate can reach 83.6%, and the average user satisfaction score is 4.6 points (on a 5-point scale).
