Longon-KZ Shampoo (Ketoconazole 2% w/v)
Longon-KZ Shampoo is a therapeutic antifungal cleanser formulated to treat and prevent scalp conditions such as seborrheic dermatitis, dandruff, and pityriasis versicolor. The active ingredient, Ketoconazole (2%), is a potent imidazole antifungal that works by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes. By targeting the Malassezia yeast—the primary culprit behind scalp flaking and inflammation—Longon-KZ effectively eliminates the root cause of the problem rather than just washing away the flakes. Its formulation is designed to provide rapid relief from intense itching and redness while helping to restore the natural balance of the scalp’s microbiome.
Key Features
- Contains a clinical 2% concentration of Ketoconazole for the effective elimination of scalp fungi.
- Significantly reduces scalp itching and irritation from the very first few washes.
- Specifically targets the oily, scaly patches and inflammation associated with severe dandruff.
- Effectively removes excess sebum and environmental pollutants that can exacerbate fungal growth.
- Helps prevent the recurrence of dandruff when used as part of a regular maintenance routine.
Key Ingredients
- Ketoconazole (2% w/v)
- Conditioning Base
Precautions
- The shampoo must be left on the scalp for a specific duration to be effective. Rinsing too early will reduce its therapeutic benefit.
- Avoid contact with eyes. If the product enters the eyes, rinse immediately with plenty of cold water.
- In rare instances, Ketoconazole can cause slight discoloration in chemically treated, bleached, or very grey hair.
- Discontinue use if you experience severe burning, swelling, or a rash on the scalp.
- Consult a healthcare professional before use, although topical absorption is generally very low.
How to Use
- Step 1: Wet the hair and scalp thoroughly with lukewarm water.
- Step 2: Apply a sufficient amount of Longon-KZ Shampoo to the scalp and massage gently to create a rich lather.
- Step 3: Leave the lather on the scalp for **3 to 5 minutes**. This is essential for the medication to work effectively.
- Step 4: Rinse the hair and scalp thoroughly with water until all traces of the shampoo are removed.
- Frequency: For active dandruff, use twice a week for 2 to 4 weeks. For prevention, use once every 1 to 2 weeks.
