Overview

Siam Ketazon Ketoconazole 2% Shampoo is a scalp shampoo that, as its name states, contains ketoconazole 2%. It is intended for people with a flaky, itchy-feeling scalp who want a dedicated scalp-care shampoo in their hair routine. The shampoo is applied to wet hair, worked into the scalp and left on briefly before rinsing, as described on the pack. Because it contains a medicinal active ingredient, it should be used exactly as directed on the label or as advised by your doctor or pharmacist.

Flaking and an itchy-feeling scalp are common complaints, and Malaysia’s hot, humid climate, frequent sweating and use of helmets or headscarves can make the scalp feel uncomfortable. A scalp-focused shampoo such as Siam Ketazon Ketoconazole 2% Shampoo is designed to be massaged directly onto the scalp rather than just the lengths of the hair. Following the recommended contact time and rinsing thoroughly are important parts of using it correctly. Many people use it alongside their regular shampoo on alternate wash days, depending on the pack directions.

Persistent scaling, redness, patches, crusting or itching that does not settle are reasons to see a doctor or pharmacist rather than simply continuing to wash with a scalp shampoo. They can help work out the cause and advise whether this product is appropriate for you. Avoid getting the shampoo in your eyes, and stop using it if your scalp becomes irritated. Always read the full label, including warnings and the list of ingredients, before use.

Directions for Use

  • Wet your hair and scalp thoroughly with water.
  • Apply a small amount of shampoo to the scalp and massage gently to form a lather.
  • Leave on the scalp for the contact time stated on the pack.
  • Rinse thoroughly with clean water, keeping the shampoo away from the eyes.
  • Use your regular conditioner on the lengths of the hair if needed.

Storage Instructions

  • Store below 30°C in a cool, dry place.
  • Protect from direct sunlight and heat.
  • Keep the cap tightly closed after use.
  • Keep out of reach of children.

Side Effects

  • Siam Ketazon Ketoconazole 2% Shampoo is generally well tolerated when used as directed.
  • Local scalp irritation, burning or stinging.
  • Dryness or oiliness of the hair or scalp.
  • Changes in hair texture or a feeling of hair being harder to manage.
  • Eye irritation if the shampoo gets into the eyes.
  • Allergic reactions such as rash, swelling or severe itching (uncommon).
  • Stop use and consult a doctor or pharmacist if any reaction persists or worsens.

Contraindications

  • Do not apply to broken, raw or severely inflamed skin.
  • Pregnant or breastfeeding women should check with a doctor or pharmacist before use.

  • If you are using other medicated scalp products or prescribed topical treatments (such as steroid lotions), ask your doctor or pharmacist before using them together.
  • Tell your doctor or pharmacist about all medicines you are taking if you are unsure whether this shampoo is suitable for you.

Quick Tips

  • Focus the shampoo on the scalp, not just the hair lengths.
  • Time the contact period so the shampoo is not rinsed off too quickly.
  • Rinse thoroughly to avoid residue on the scalp.
  • Wash pillowcases, caps and headscarves regularly.
  • Do not share towels or combs.
  • See a doctor or pharmacist if flaking or itching persists.
