Potential benefits of keratin treatment
The body naturally makes the protein keratin. It’s what hair and nails are made up of.
The keratin in these treatments may be derived from wool, feathers, or horns. Certain shampoos and conditioners contain keratin, but you’ll typically get the most significant benefits from a salon treatment done by a professional.
The benefits of getting a professional keratin treatment or doing one at home can include:

Smooth, shiny hair
It adds intense glossy shine to hair and can reduce frizz. Keratin smooths cells that overlap to form hair strands, which means more manageable hair and less frizz. This results in hair that dries with little frizz and has a glossy, healthy look. Keratin can also reduce the look of split ends by temporarily bonding the hair back together. Some formulations can smooth curls, making them appear softer.

Chemically straightened hair
A keratin treatment can make your hair look straighter for up to 6 months.

Thicker looking hair
Replenishing the keratin in your hair can cause it to look thicker.

More manageable hair
Keratin treatments make hair more manageable, especially if your hair is particularly frizzy. If you constantly heat style your hair, you’ll notice that a keratin treatment makes it dry more quickly. Some people estimate that keratin cuts their drying time by more than half. Your hair may also become healthier and stronger because you can air dry it more often, preventing heat damage.

Hair growth
Keratin can strengthen and fortify hair so it doesn’t easily break off. This can make hair seem to grow faster because the ends aren’t breaking off.
