10 Best Keratin Treatment At Home 2025 in the United States

GK HAIR The Best Keratin Treatment offers a professional-level smoothing experience you can do at home, designed to reduce frizz and soften curls for up to five months. Its formula includes natural seed oils and an anti-aging keratin protein that help repair damaged hair, deeply condition strands, and add a healthy shine. This treatment works well on all hair types, making it versatile if you have anything from wavy to very curly hair.

The application is straightforward, but since it's a liquid treatment that temporarily straightens hair, some care is needed to follow instructions closely for best results. It effectively smooths the hair cuticle and makes styling easier by reducing natural curl patterns, which is great if you want sleek, manageable hair without frequent salon visits. However, because it’s a temporary solution, the effects gradually fade after a few months, requiring reapplication to maintain the look.

Also, while it’s marketed as strengthening, some users might find that its smoothing effect is more about surface shine and frizz control rather than deep structural hair repair. This treatment is a strong choice for anyone seeking a long-lasting, at-home keratin treatment that leaves hair shiny and frizz-free with relatively simple use.

Lasio Keratin One Day Treatment offers an easy at-home solution for controlling frizz and smoothing hair. Its cream formula includes keratin, which helps strengthen damaged or dry hair and adds a natural shine. The treatment promises instant frizz elimination and hydration, making hair feel softer and more manageable even in humidity.

One of its biggest advantages is that it suits all hair types—whether curly, straight, color-treated, or damaged—and doesn’t require waiting time; you can wash your hair the same day. This makes it convenient for quick use without the fuss of long processing times. The formula also locks in moisture, improving elasticity and giving a silky finish.

While it’s a one-day treatment, the smoothing effects may not last as long as more intensive professional keratin treatments that require heat and longer application. Those with very coarse or severely damaged hair might find the results less dramatic. This product is a solid choice for anyone looking to tame frizz, hydrate, and strengthen hair with minimal effort and time, especially if you prefer a cruelty-free product and want salon-like results from home.

The Keratin Complex NKST Natural Keratin Smoothing Treatment Kit is designed for at-home use and aims to provide smoother, straighter hair lasting up to 3 months, with some claims up to 5 months depending on use. It includes a powerful three-step system that combines a specialized keratin formula with modern smoothing technology. The formulation comes in a lotion form and is unscented, which is a plus for those sensitive to strong smells. The product is suitable for all hair types, making it versatile whether you have curly, wavy, or straight hair.

The application might require some careful attention to the instructions, as keratin treatments generally involve multiple steps and timing to achieve the best results. The kit promises healthy and manageable hair, though such treatments often need maintenance and might not work the same for everyone, especially if hair is very damaged or chemically treated. Packaged in a large 67.6 oz size, the kit offers good value for those who want to do multiple treatments or share with family members.

This product is well-suited for individuals looking for a strong, lasting smoothing treatment at home, provided they carefully follow the steps and consider their hair's condition before use.
