10 Best Straightening Shampoos 2025 in the UK

The Redken Frizz Dismiss Shampoo is designed to cater primarily to those with curly hair, promising to tame frizz and smooth out unruly locks. Its primary ingredient, Babassu Oil, is known for its nourishing and hydrating properties, which helps in enhancing hair shine and sealing cuticles for a sleeker look. This makes it suitable for users dealing with frizz and seeking a smoother finish to their hair. It also comes in a decent 300ml size with a promise of 66 percent more product, making it economical for daily use.

A notable omission in its feature list is heat protection, which might be a concern for users who frequently use heat styling tools. The shampoo is fragranced with a citrus scent, which could be refreshing but might not appeal to those sensitive to strong odors. Redken as a brand has a solid reputation in haircare, which can provide assurance of quality and effectiveness.

While it excels in moisturizing properties and tackling frizz, it lacks specific mention of other ingredients that might cater to different hair needs or preferences. If your primary concern is managing frizzy, curly hair, this shampoo could be a strong candidate. But if you're looking for additional straightening or heat protection benefits, you might need to supplement it with other products or heat protectants.

The John Frieda Frizz Ease Brazilian Sleek Frizz Immunity Smoothing Shampoo and Conditioner Duo is a noteworthy option for those battling frizzy, medium to coarse hair. This product shines with its ability to tame unruly frizz, thanks to the inclusion of a frizz immunity complex and keratin drops, which are known for smoothing and enhancing hair's shine. Users have praised its ability to leave hair sleek and glossy, making it a practical choice for those looking to achieve long-lasting, smooth hairstyles.

The fruity scent adds a pleasant aroma, which can be a delightful feature for users who enjoy fragrant hair products. The generous salon-size bottles with convenient pumps make it easy to use and suitable for long-term application, providing good value for frequent users.

However, while this duo is especially formulated for frizzy and medium to coarse hair, it may not suit all hair types. Those with fine or oily hair might not receive the same benefits and might find the product too heavy. Additionally, while the product provides frizz management, it does not specifically mention heat protection, which might be a limitation for users who regularly use heat styling tools.

John Frieda is a well-regarded brand, known for its hair care products, which adds a layer of trust and reliability to this duo. With a customer review rating of 4.4 out of 5 stars, it has received positive feedback for its performance. However, potential buyers should consider their specific hair type and styling needs to ensure it aligns with their expectations.
