Keratin Conditioners: What Type and Brand Should You Use

Last Updated on December 16, 2022 by Gaga

Natural keratin production in the body slows down as we age, leaving our hair dull, weak, and vulnerable to damage. Exposure to chemicals, frequent heat styling, and harsh environmental conditions can also lead to keratin loss and weakened hair structure.

Since keratin is a major component of human hair, it sounds logical that adding keratin protein to hair products can provide multiple benefits. Over time, using hair products enriched with keratin can help replenish the lost keratin and temporarily fix damaged hair fibers.

If your hair is weak or damaged, there is a good reason why you should include keratin-enriched daily conditioners, deep conditioners, and leave-in treatments in your hair care regimen.

Keratin-rich hair conditioners help retain moisture and preserve the integrity of the hair. Your hair will be stronger, softer, and more resilient to future damage.
