K18 is one of those hair-care brands where the same product can carry very different price tags from one Iraqi store to another. For the week of 26 October–2 November 2026, TajPrice compared K18 listings across hair-care subcategories — masks, shampoos, conditioners, oils, heat protectants and mini sets — and ranked the products by cross-store price spread. A bigger spread means a bigger chance to save simply by checking more than one store before you buy. All prices are in Iraqi dinars and reflect the best available prices during this weekly update; always confirm the final price, stock and delivery before checkout.
Here are the 10 K18 products with the biggest price gaps this week.
1) 
K18 Biomimetic Hairscience Future Faves Minis — Best price: 49,000 IQD. Available at 3 stores. Price range: 49,000–77,000 IQD. Spread: 57.1%. Potential saving: up to 28,000 IQD. This is the clear number-one saver this week. The gap is wide enough that a quick comparison can cover a big part of another hair-care purchase. If you want to test more than one step in a routine, this is the option where checking store prices matters most.
2) 
K18 Damage Shield Conditioner — Best price: 28,000 IQD. Available at 2 stores. Price range: 28,000–41,750 IQD. Spread: 49.1%. Potential saving: up to 13,750 IQD. The spread is close to 50%, so the difference is not small. This option is designed to help protect hair from daily damage while improving softness and shine, so shoppers should compare both stores before choosing.
3) 
K18 Damage Shield Ph Protective Shampoo , 250 ml — Best price: 26,600 IQD. Available at 2 stores. Price range: 26,600–38,000 IQD. Spread: 42.9%. Potential saving: up to 11,400 IQD. A pH-balanced shampoo can be an important part of a damaged-hair routine, and this week the store gap is large enough to justify a quick check. At the lower price, it is a more comfortable add-on to a repair-focused basket.
4) 
K18 Leave-In Consumer Hair Mask - 5ml — Best price: 13,050 IQD. Available at 2 stores. Price range: 13,050–18,500 IQD. Spread: 41.8%. Potential saving: up to 5,450 IQD. This small-size option is a low-commitment way to try the routine, and the percentage gap is still significant. If you are buying several items, saving here can help balance the total.
5) 
Leave-In Molecular Repair Hair Mask — Best price: 61,750 IQD. Available at 3 stores. Price range: 61,750–82,500 IQD. Spread: 33.6%. Potential saving: up to 20,750 IQD. This is one of the higher-ticket items on the list, so the cash difference is especially noticeable. Comparing all three stores is worthwhile because the highest price is over 20,000 IQD above the best price.
6) 
K18 Molecular Repair Hair Oil - 30ml — Best price: 62,000 IQD. Available at 5 stores. Price range: 62,000–79,000 IQD. Spread: 27.4%. Potential saving: up to 17,000 IQD. With five stores in the comparison, shoppers have more chances to find a better deal. The spread is smaller than the top four, but the cash saving is still meaningful for a premium hair oil.
7) 
K18 - Peptide Detox Shampoo 250ml — Best price: 36,250 IQD. Available at 3 stores. Price range: 36,250–46,000 IQD. Spread: 26.9%. Potential saving: up to 9,750 IQD. This option is aimed at scalps and hair dealing with oil, buildup or heavy styling products. The price gap is moderate, but checking the three stores can still keep nearly 10,000 IQD in your pocket.
8) 
K18 HeatBounce Conditioning Heat Protectant - 118ml — Best price: 55,000 IQD. Available at 4 stores. Price range: 55,000–69,750 IQD. Spread: 26.8%. Potential saving: up to 14,750 IQD. For shoppers who use heat styling, protection matters, and so does the price. Four stores are listed, so it is worth comparing before you settle on the first price you see.
9) 
K18 DAMAGE SHIELD protective conditioner, 250ml — Best price: 38,000 IQD. Available at 2 stores. Price range: 38,000–46,000 IQD. Spread: 21.1%. Potential saving: up to 8,000 IQD. The gap is smaller, but 8,000 IQD is still a useful saving. This is a good example of why even a two-store comparison can be worth the extra minute.
10) 
K18 Leave-in Molecular Repair Hair Mask - 15ml — Best price: 47,750 IQD. Available at 2 stores. Price range: 47,750–55,250 IQD. Spread: 15.7%. Potential saving: up to 7,500 IQD. It has the smallest spread on this week’s list, but it still shows that the same item is not priced the same everywhere.
Quick buying tip for this week: start with the items at the top of the list if you want the biggest percentage savings, but also look at the cash difference. Products 1 and 5 have the largest potential cash gaps, while products 1, 2 and 3 have the widest percentage spreads. If you are building a full K18 routine, compare each item separately instead of assuming one store is cheapest for everything. Prices and availability can change, so use TajPrice to check the latest listing before you buy.
