If you’re a fan of K18’s science-backed hair repair, you know the products work wonders — but the prices can vary a lot between stores. This week (August 11–18), we’ve crunched the numbers on TajPrice to find the K18 items with the biggest cross-store price spreads. These are the deals where comparing prices can save you serious dinars. Let’s dive in.
First up, the biggest gap of the week: 
K18 Biomimetic Hairscience Future Faves Minis. This mini set includes three essentials — Detox Shampoo, Leave-In Repair Mask, and more — and the price jumps from 59,400 IQD to 77,000 IQD across three stores. That’s a 29.6% spread. If you grab it at the best price, you save nearly 18,000 IQD. Perfect for trying the full routine without committing to full sizes.
Next, the 
K18 Leave-In Consumer Hair Mask - 5ml is a travel-friendly or trial-size option. It’s available at two stores with a 22.6% spread: from 13,050 IQD to 16,000 IQD. The 5ml size is ideal for a quick repair boost, and the savings of almost 3,000 IQD make it a smart buy.
Moving to a full-size treatment, the 
Leave-In Molecular Repair Hair Mask (50ml) has a 15.8% spread. Prices range from 61,750 IQD to 71,500 IQD across three stores. This mask is the brand’s hero product — it repairs damaged bonds in just four minutes. By choosing the cheapest store, you save nearly 10,000 IQD.
For those who need a deep clean, the 
K18 - Peptide Detox Shampoo 250ml shows a 12.5% spread: 36,000 to 40,500 IQD. Great for removing buildup from heavy styling products. The 4,500 IQD difference might not seem huge, but every bit counts when you’re stocking up.
The 
K18 Molecular Repair Hair Oil - 30ml is available at five stores, with prices from 62,000 to 68,750 IQD — a 10.9% spread. This oil works on two levels to fight frizz and strengthen hair. With 6,750 IQD in potential savings, it’s worth checking the best price before you buy.
Conditioners are also in the spotlight. The 
K18 Damage Shield Conditioner (unspecified size, likely 250ml) has a 10.7% spread: 37,700 to 41,750 IQD across two stores. It protects against daily damage and improves softness. Saving 4,050 IQD is a nice bonus.
If you use heat styling, the 
K18 HeatBounce Conditioning Heat Protectant - 118ml is a must. It shields up to 232°C and prevents colour fade. With a 10% spread (55,000 to 60,500 IQD) across four stores, you can save 5,500 IQD.
A special edition item, the 
K18 x Future Society Leave-In Molecular Repair Hair Mask - 50ml also has a 9.7% spread: 70,200 to 77,000 IQD. This collaboration version offers the same 4-minute repair in a sleek package. The 6,800 IQD difference is worth noting.
Another conditioner option: the 
K18 DAMAGE SHIELD protective conditioner, 250ml (note: different slug from above) has a 9.2% spread: 38,000 to 41,500 IQD. It provides up to three days of protection against UV and environmental damage. Saving 3,500 IQD is easy with a quick comparison.
Finally, the 
K18 Damage Shield Ph Protective Shampoo , 250 ml has the smallest spread this week at 4.8% (36,250 to 38,000 IQD). Still, 1,750 IQD saved is better than nothing. This pH-balanced shampoo is gentle on chemically treated hair.
