Five Keratin Leave-In Conditioners for Stronger and Smoother Hair

Last Updated on October 3, 2021 by Gaga

Keratin is a major component of human hair and protecting it is crucial to have strong and flexible strands. Keratin content decreases with age, resulting in weak, lifeless, and brittle hair. Other factors that may cause keratin damage are frequent heat styling, regular coloring, and harsh chemical treatments. When keratin in your hair gets depleted, your hair is dry, frizzy, and prone to tangles.

If you want to strengthen, straighten, and revive your dry, lackluster hair, you should consider using hair products infused with keratin. Keratin enriched hair care products can improve the structure of hair fibers and keep your locks in top condition. Keratin particles in the form of hydrolyzed proteins and amino acids fill the gaps in the hair shaft, making your hair stronger, shinier, and easier to style.

What a Keratin Leave-in Sprays Can Do for Your Hair?

Leave-in conditioner enriched with keratin is a hair product that you leave in the hair between shampoos to restore depleted keratin levels and lock in moisture. It offers multiple benefits to weak, porous, and frizzy hair:

Shields from damage: A keratin leave-in conditioner can greatly reduce the risk of hair damage when you use it before blow-drying and straightening. It also rebuilds hair’s cuticle and makes your locks stronger, thicker, and less prone to breakage.

Tames frizz: Curly/coarse hair types are naturally prone to frizz that can be a nightmare to deal with. Keratin leave-in products make dry curly hair smooth, frizz-free, and manageable. They make your curls beautifully smooth and shiny.

Prevents tangles: To keep your hair tangle-free and easy to comb, apply a fine mist of leave-in keratin spray over your damp hair. This will also help reduce porosity and split ends.

Keratin Leave-In Treatments that are Worth Your Attention

1. Expensive, but it may Worth it: VIRTUE Smooth Conditioner

This conditioner is formulated with Alpha Keratin 60ku(R) – a protein that is almost identical to the hair’s natural keratin.

Keratin particles bind to areas of damage and fill the gaps in the hair shaft, leaving your hair stronger, shinier, and dramatically smoother.

VIRTUE Smooth Conditioner works as a daily smoothing treatment. It repairs and smoothes the cuticle to lock in moisture and reduce friction between hair strands. This results in tangle-free and frizz-free hair.

The company claim that their Smooth Conditioner reduces frizz up to 95% after four applications. It takes five applications to repair split ends up to 95%. A single strand becomes 22% thicker after just one application, creating added volume. Finally, color vibrance increases by up to 138% after five applications.

According to these claims, frizz-prone, dry, or curly hair will get the most benefits. It also may be worth considering if you frequently color and bleach your hair.

Hydrolyzed Keratin vs. Keratin

Keratin molecules have a high molecular weight and can’t penetrate the hair shaft. These keratin molecules just attach to the hair surface, and despite the benefits they provide, they can make your hair look heavy and greasy. Hydrolyzed keratin, however, has a very low molecular weight, which allows the protein particles to penetrate the hair shaft and rebuild the hair from the inside instead of just coating hair strands.
