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.

The Keratin Complex Color Care Smoothing Shampoo & Conditioner Duo is designed for anyone with color-treated hair, but it works well on all hair types. One of its strengths is that it not only protects your hair color but also hydrates and adds shine, which helps keep your hair looking vibrant. The formula includes natural ingredients like lavender oil, which can encourage hair growth, and wheat and oat proteins that help make your hair stronger and more resistant to heat styling and damage from the sun or daily wear. It’s also free of parabens, which is a bonus if you want to avoid certain chemicals.

The product is creamy in texture, which usually means it’s gentle and moisturizing. While it doesn’t specifically mention heavy frizz control, the smoothing benefits suggest it can help manage frizz to some degree. The scent includes lavender, which many find pleasant and calming but may not suit everyone’s preference. This duo is gentle enough to be used regularly, making it a good choice for daily or frequent use without stripping your hair.

A limitation is that it doesn’t target very specific hair concerns like extreme dryness or intense frizz, so if those are your main issues, you might need a more specialized product. This shampoo and conditioner set is a solid option if you want to maintain color, add moisture, and gently smooth your hair with natural ingredients, especially if you prefer a paraben-free formula.

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.
