Posted by Sarah Arif on

Keratin hair treatment is a popular hair smoothing treatment that uses keratin, a natural protein found in hair, to help restore and repair damaged hair. However, before considering this treatment, it is important to weigh the pros and cons to determine if it is the right choice for you.

Pros of Keratin Hair Treatment

A. Restores natural proteins in the hair

Keratin hair treatment helps to replenish natural proteins in the hair, improving the strength and elasticity of the hair, reducing breakage, and promoting hair growth.

B. Makes hair smooth, shiny, and more manageable

The treatment smooths and tames unruly hair, leaving it soft, silky, and easy to manage. It also adds a healthy shine to the hair, giving it a natural glow.

C. Results last for several months

The results of keratin hair treatment can last for several months, depending on the type of treatment and how well it is maintained.

D. Reduces frizz and tames curly hair

The treatment helps to reduce frizz and tame curly hair, making it more manageable and easier to style.

Works on all hair types

Keratin hair treatment is effective on all hair types, including straight, wavy, curly, and kinky hair.

Cons of Keratin Hair Treatment

A. Costly treatment

Keratin hair treatment can be expensive, and the cost varies depending on the salon and the type of treatment.

B. Can be difficult to maintain

Maintaining keratin-treated hair requires special care and products, and it may take longer to style your hair due to the treatment's smoothing effects.

C. Contains formaldehyde, which can be harmful

Formaldehyde is a chemical used in some keratin hair treatments to help bond the hair. It can be harmful if inhaled or absorbed through the skin.

D. May cause scalp irritation or hair damage

Some people may experience scalp irritation or hair damage from the treatment, especially if it is not done correctly or if the wrong type of treatment is used.

E. Not a permanent solution

Keratin hair treatment is not a permanent solution, and the effects will gradually wear off over time.

F. Not suitable for severely damaged hair

Keratin treatments work by filling gaps and cracks in the hair cuticle. However, if your hair is severely damaged, it may not be able to withstand the treatment. In fact, keratin treatment can worsen the condition of extremely damaged hair.

G. Requires a skilled stylist

Keratin treatment is a complex process that requires skill and expertise. If the treatment is not done correctly, it can damage your hair and scalp.

Types of Keratin Treatments

A. Formaldehyde-based treatments

Formaldehyde-based treatments use formaldehyde to help bond the hair, resulting in longer-lasting effects but with potential health risks.

B. Formaldehyde-free treatments

Formaldehyde-free treatments use alternative ingredients to bond the hair, making them a safer option but with shorter-lasting effects.

C. Home treatments

There are also keratin hair treatment kits available for home use, but they may not be as effective as salon treatments and could lead to hair damage if not used correctly.

How Keratin Treatment Works

A. Step-by-step process

Keratin hair treatment involves washing the hair, applying the treatment, blow-drying the hair, and then flat ironing it to seal in the treatment.

B. Duration of treatment

The treatment can take anywhere from 2 to 4 hours, depending on the length and thickness of the hair.

C. Things to avoid after treatment

After the treatment, it is important to avoid washing your hair for at least 24 to 48 hours and to use sulfate-free shampoo and conditioner to maintain the treatment's effects.

Aftercare for Keratin Hair Treatment

A. Washing hair after the treatment

It is important to wait at least 24 to 48 hours before washing your hair after the treatment to allow the treatment to fully set in.

B. Using sulfate-free shampoo

Using sulfate-free shampoo and conditioner can help maintain the treatment's effects and prevent damage to the hair.

C. Avoiding harsh chemicals

After a keratin hair treatment, it is essential to use hair products that do not contain harsh chemicals such as sulfates, chlorine, and salt. These chemicals can strip the keratin treatment from your hair and cause damage. Instead, opt for gentle hair products that are specifically formulated for chemically treated hair.


Can I color my hair after a keratin treatment?

Yes, you can color your hair after a keratin treatment, but it is recommended to wait at least two weeks after the treatment to give your hair time to recover. It is also important to use hair color that is specifically formulated for chemically treated hair.

How long does keratin treatment last?

The duration of a keratin treatment depends on several factors, such as the type of treatment used, the condition of your hair, and how well you maintain your hair after the treatment. Generally, a keratin treatment can last between three and six months.

Can I go swimming after a keratin treatment?

It is recommended to avoid swimming in chlorinated or saltwater pools for at least a week after a keratin treatment. If you must swim, wear a swimming cap to protect your hair.

Is it safe to get a keratin treatment while pregnant?

There is limited research on the safety of keratin treatments during pregnancy, so it is best to consult with your healthcare provider before getting a keratin treatment if you are pregnant.

How often can I get a keratin treatment?

It is recommended to wait at least three months between keratin treatments to give your hair time to recover. Over-treating your hair with keratin treatments can cause damage, so it is important to space out treatments appropriately.
