K18 has become one of the most searched hair care names in Iraq, especially for damaged, colored and heat-styled hair. In this weekly TajPrice update for September 15–22, 2026, we rounded up the most popular K18 products available across multiple Iraqi stores. Prices are in IQD and can change fast, so use the price range as a guide and check the live listing before you buy. The biggest opportunity this week is in the mini set, where the spread reaches 29.6%. The tightest spread is the color-safe shampoo at 1.3%, so there is little difference between stores on that one.

It cleans gently while helping maintain the hair’s integrity. The spread is small, so availability and shipping may matter more than saving a few dinars, but the lower price is still the better deal.

10.

Best price: 39,500 IQD across 2 stores. Range: 39,500–40,000 IQD, a 1.3% spread. This pH-optimized color-safe shampoo uses microdose protein and is formulated to clean without stripping natural oils, making it suitable for daily use on colored hair. The spread is tiny, just 500 IQD, so buy from the store with better delivery or stock.
Final buying tips for this week: if your priority is repair, start with the leave-in mask or the 5ml trial. If frizz and heat are your main issues, the hair oil and heat protectant are the strongest picks. For buildup or heavy product use, the detox shampoo is the clear match. For colored hair, the pH-optimized shampoo and Damage Shield options make sense. Always confirm authenticity, expiry and shipping cost in Iraq before ordering, and remember that TajPrice prices are a weekly snapshot for September 15–22, 2026.
