10 Best Keratin Shampoos 2025 in the United States

Pureology Strength Cure Shampoo is designed to cater to adults with damaged and color-treated hair. One of its standout features is its ability to repair hair damage by up to 97%, making it a solid choice for anyone struggling with split ends or the effects of heat styling. The formula is enriched with plant-based protein Keravis, which strengthens hair strands, and Astaxanthin, an antioxidant that helps heal and protect the hair from further damage. Its sulfate-free and paraben-free composition makes it suitable for those with color-treated hair, ensuring your color remains vibrant while also getting the nourishment it needs.

The scent is another appealing aspect, featuring a refreshing blend of water flower, raspberry, and peach, which can make your hair care routine feel more enjoyable. This shampoo's moisturizing properties are effective, as it cleanses without overly stripping the hair of its natural oils, helping to soften and smoothen the hair, which is essential for frizz control.

If you're considering daily use, it's worth noting that while the shampoo is rich and effective, some may find it a bit heavy for frequent application, especially if they have fine or oily hair. Additionally, the price point can be on the higher side compared to typical shampoos, which may not appeal to budget-conscious shoppers. Those with extremely oily scalps might need to follow up with a clarifying shampoo occasionally to avoid any buildup.

Pureology Pure Volume Shampoo is specifically designed for flat, fine, color-treated hair, making it a solid choice for anyone looking to boost their hair's volume and texture. One of its standout features is its lightweight formula, which not only enhances volume but also clarifies the scalp, helping to remove buildup that can weigh hair down. The inclusion of Wheat Protein and Eucalyptus Leaf Extract is beneficial, as they contribute to both volume and overall hair health, promoting growth and vitality. This shampoo is vegan and free from sulfates and parabens, which adds to its appeal for those seeking a more natural and gentle hair care option.

The scent of eucalyptus is refreshing, providing a pleasant experience during use, but scent preferences can vary significantly among users. While the product excels in volumizing and is suitable for all hair types, it particularly shines for those with fine hair. However, individuals with very thick or curly hair might find it less effective in terms of moisture retention; they may require additional conditioning to manage dryness or frizz.

In terms of frequency of use, the shampoo is suggested to be applied as needed, with the option for a second cleansing if desired. This flexibility can be great for users who appreciate tailoring their hair care routine according to their specific needs. One potential drawback is that those unfamiliar with sulfate-free products may need to adjust their expectations regarding lather and cleansing power.

This shampoo is a great choice for anyone needing volume and a light cleansing experience, especially in the realm of color-treated hair. However, users with thicker or curlier hair types might want to test its moisturizing capabilities first to ensure it meets their specific needs.

The Bellisso Keratin Shampoo and Conditioner Set is designed to work well for all hair types, including dry, damaged, curly, frizzy, straight, and color-treated hair. Its main strength lies in the keratin protein, which helps strengthen hair strands and reduce breakage by forming a protective barrier. This can be especially helpful if your hair feels brittle or prone to split ends. The formula is sulfate and paraben free, making it gentle on the scalp and less likely to strip away natural oils, which suits those with sensitive scalps or who prefer milder products.

The set also includes nourishing ingredients like argan oil, collagen, vitamin B5, and silk protein, which provide added moisture and help smooth frizz without weighing hair down. Users looking to improve shine and manageability will appreciate these benefits. Since it is a salon-grade product, it is aimed at people wanting professional-level care at home and is gentle enough for frequent washing.

One potential downside is that while the set claims to work for all hair types, very fine hair might find the thickening formula a bit heavy. Additionally, those expecting an intense fragrance or very fast results might find its effects more subtle. This set suits anyone seeking stronger, smoother hair with reduced frizz, especially if they want a sulfate-free option that supports hair health without harsh chemicals.
