Home Bargains Slashes Mizani Smoothing Shampoo Price, Receives Mixed Customer Reviews

Home Bargains has slashed the price of Mizani Press Agent Thermal Smoothing Sulfate-Free Shampoo by 85%, from £39.99 down to just £5.99. OK Magazine reports the deal has sent bargain hunters rushing online, with the 1,000ml professional-sized bottle selling out fast in stores.
The shampoo — normally a salon staple — is a L'Oréal-owned product designed for high-heat styling. The Mirror notes Home Bargains describes it as having "reparative and protective properties," promising soft, sleek results. But not every shopper agrees.
Mizani is a professional hair brand founded in 1991 in Chicago for the Black salon market. L'Oréal bought it in 2001. Its products typically sell only through salons. Seeing it on a discount retailer's shelves — or website — is unusual. The 1,000ml size is a "back bar" bottle, meaning it is made for salon use across roughly 30 to 50 washes.
Daily Star confirms the bottle's original retail price was £39.99. At £5.99, shoppers save £34 per bottle. Similar thermal or smoothing shampoos of this size typically cost between £20 and £45. That makes this one of the steepest hair care discounts seen at a UK high street retailer in recent memory.
When premium salon brands appear at places like Home Bargains, there are usually a few reasons. The brand may be updating its packaging, making old stock useless to salons. Or L'Oréal may be moving Mizani from its professional range into its consumer range. Either way, surplus stock gets sold to third-party suppliers, who then pass it to discount retailers.
Home Bargains has over 600 UK stores. The Mirror notes this deal is online-only for home delivery, suggesting limited central stock. The retailer has been building a reputation as a beauty destination, with other high-end brands like Christophe Robin and Sebastian Professional also recently appearing at 80%-plus discounts.
Reviews are mixed. On the positive side, customers cited by The Mirror say their hair feels "beautiful and silky soft" and that the shampoo "worked well" for their hair type. The product contains argan oil and agave extract, which are designed to protect against heat, UV rays, and humidity.
But a growing number of buyers say they saw "no visible effects" despite regular use. Hair experts suggest this may be because the shampoo is heat-activated. Without a blow-dry or flat iron at high heat, the formula may leave hair feeling heavy rather than smooth. In short: it works best as part of a full heat-styling routine, not a wash-and-go.
The Mizani Press Agent shampoo is not currently available in Home Bargains stores. Liverpool Echo confirms shoppers must order it online for home delivery. Stock has moved quickly since the deal went viral on UK bargain-hunting groups and social media in mid-June 2026.
For those who do buy it, experts recommend using it alongside a heat-styling step to get the best results. Without a blow-dry or flat iron, the thermal-smoothing ingredients may not activate properly. At £5.99 for a litre, though, the risk is low — even if results vary.
