9 Best Straightening Cream 2025 in the United States

The Kerastase Discipline Keratine Thermique Blow Dry Primer Serum is a versatile product designed for all hair types, making it inclusive for a wide range of users. It offers excellent heat protection, safeguarding hair from temperatures up to 450°F, which is ideal for those who frequently use heat styling tools. The inclusion of ceramides helps strengthen the hair and prevent future damage, which is a significant advantage for maintaining long-term hair health.

Additionally, its ability to smooth frizz and control flyaways is beneficial for achieving sleek, polished hairstyles, especially in humid conditions. The serum also enhances the appearance of split ends and adds a noticeable shine, contributing to healthier-looking hair. However, the product requires an additional step of blow-drying after application, which might be less convenient for users looking for a quick fix.

While it is paraben-free, users with specific material sensitivities should note that it doesn't mention being free of other common allergens. The suggested use alongside other products in the Discipline Collection could imply better results, potentially increasing the cost. For those who prioritize comprehensive hair care and are willing to invest the time and money, this product provides robust benefits.

The Kerastase L'incroyable Blow dry Hair Lotion is designed for fine to normal hair types, making it accessible for a broad audience but may not be ideal for those with very thick or coarse hair. It offers a significant level of straightening and styling flexibility, allowing users to reshape their hair multiple times with heat tools while maintaining the desired look. This makes it particularly useful for those who enjoy frequently changing their hairstyles.

The product provides excellent heat protection up to 450°F, ensuring that your hair remains safe from heat damage during styling. Its moisturizing properties come from ingredients like Glycerin and Beeswax, which help to keep the hair soft and shiny. Additionally, it excels in frizz control, leaving the hair smooth and ready for any occasion. The application method is straightforward: apply to towel-dried hair before blow-drying or using other heat tools. However, it may require a learning curve for those not used to incorporating such products into their routine.

While it is paraben-free and unscented, which is a plus for those with sensitivities, its performance is best complemented with other products like hairspray for lasting hold. It's a versatile product but might not fully meet the needs of those with specific hair types or those looking for a product with a strong scent or additional benefits. Its relatively high price point might also be a consideration for budget-conscious consumers.

The Brazilian Blowout Protective Thermal Straightening Balm is suitable for individuals with frizzy hair looking to achieve straighter, smoother locks. This product is particularly effective at straightening waves and curls, providing a high level of frizz control. Additionally, it offers significant heat protection, which is ideal for those who regularly use blow dryers or other heat styling tools.

The balm must be applied generously to towel-dried hair from roots to tips and then blow-dried with medium to high tension for best results. Furthermore, the balm's citrus/grapefruit scent is pleasant, and it is free of parabens and gluten, making it a safer option for those with sensitivities to these ingredients. However, some users might find the application process a bit time-consuming as it requires meticulous blow-drying.

While it excels at straightening and frizz control, it doesn't highlight any moisturizing properties, which might be a drawback for users seeking hydration in their hair care routine. Therefore, this product is a solid choice for those primarily focused on achieving straight, frizz-free hair with heat protection.
