What is a keratin treatment?

Keratin is a key protein found in our hair that is produced naturally. It protects and maintains the health of your hair by acting as an exterior protective and inside the structural protein. The keratin in your hair is lost as a result of exposure to external elements such as the sun, pollution, or chemicals, as well as changes in your lifestyle, leading to dry, damaged, and lifeless hair.

A keratin treatment smoothes and shines frizzy hair via a chemical technique. Keratin is chemically added to the hair during a keratin treatment to make it seem smooth, lustrous, and frizz-free, making it immensely popular among women and men. These treatments fill up the porosity patches in your hair that has developed as a result of keratin loss. Frizz, knots, and breakage are all caused by too porous hair. A keratin treatment simply rebuilds your hair by replacing the protein that has been lost in your strands.

Types of keratin treatments

Brazilian blowout

This was one of the first keratin treatments to be created and introduced in Brazil in 2005. By coating strands in a protective protein layer, it removes frizz and smoothes the hair cuticle. Its effects might continue for up to three months.


This keratin hair treatment is the most natural and formaldehyde-free option. Cezanne is ideal for fine hair since it not only reduces frizz but also nourishes strands that have been damaged. If you have colored hair, you should avoid this since it might cause your blonde to fade. 

Trisolla and Trisolla Plus

These keratin hair treatments are the easiest to apply. They’re ideal for those who have thick hair that’s been damaged or dyed. The amount of times each strand is flat-ironed affects the softness of the curl texture. The procedure doesn’t lessen hair color, but it does make it manageable and keeps it in place in hot and humid conditions.

Keratin express

This is a quick treatment that involves applying keratin serum to the hair and sealing it with a blow dryer and flat iron. It’s perfect for people who have wavy or curly hair and want to make it more manageable. It might take up to six weeks for the effects to wear off.

Japzilian keratin

The Japzilian combines Brazilian keratin treatment with a Japanese hair straightening system to provide results that last five months longer than the Brazilian blowout. Curls are first loosened with the Brazilian treatment, then sealed with the Japanese treatment, which closes the cuticle and keeps frizz at bay. Hair is brushed through with a Japanese straightening perm, and coarse strands are treated twice. After an hour, the hair is washed and blow-dried one more for smooth hair that air-dries absolutely straight.

Pros of keratin treatments

Silky and glossy hair

Keratin works by smoothing out the overlapping cells that make up your hair strands. The hair cuticle, which is made up of layers of cells, absorbs the keratin, giving hair a full and glossy appearance. Keratin is also said to make curly hair less frizzy, simpler to style, and seem straighter.

Easy to manage hair

Keratin treatments help to make hair more manageable, especially if you have frizzy or thick hair. Moreover, if you often heat style your hair, a keratin treatment is a factor that makes your hair dry quickly. Keratin reduces drying time by more than half. Because you can air-dry your hair more regularly and avoid heat damage, it may become healthier and stronger.

Hair growth

Keratin may strengthen and reinforce hair, making it less prone to breakage. Because the ends aren’t breaking off, hair seems to grow faster.

Cons of keratin treatments

Formaldehyde is present in high concentrations in-salon keratin treatments. Handling keratin treatment materials and breathing their fumes repeatedly over time caused nosebleeds and respiratory difficulties in hair salon staff. According to a study by PubMed Central, these levels of formaldehyde were five times higher than the national safety threshold for chemical exposure. As a result, pregnant women should refrain from receiving this therapy. Keratin treatments should be avoided by anyone with formaldehyde sensitivity or respiratory difficulties.

Methods to use 

Salon-keratin treatments

This time-consuming keratin treatment, often known as the Brazilian keratin treatment, entails multiple phases. First, a formaldehyde-containing lotion is applied to your hair before it is blown dry and straightened at a salon. After applying the treatment, you are encouraged to leave your hair dry for several days. When you go to the salon to have the chemicals removed, another treatment is used to set the straightening result. This therapy is supposed to last 12 weeks.

Add keratin serums

When a keratin-infused styling serum is applied while the hair is still wet, it not only makes the hair glossy and smooth but also reduces drying time.

Use as a shampoo and conditioner

Keratin shampoos and conditioners can make hair stronger, more resistant to harm and restore hair that has been dried out by heat and hair color.

Repairing hair mask

Use a keratin-infused hair mask to help restore color-treated or heat-damaged hair for ultra-dry and damaged locks. Apply this mask to damp hair once a week and let it in for 5 minutes. Rinse thoroughly and style as usual.

Keratin supplements

Keratin supplements are available as powder or capsules. Supplementing with keratin carries certain hazards. They might cause too much protein to build up in your body if used excessively.
