10 Best Keratin Shampoos 2026 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 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.

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.
