What Are the Benefits of Keratin Treatment?

Keratin treatments benefit the hair by improving the health and structure of the hair by replenishing depleted keratin levels in human hair.

Hair keratins are the major structural proteins in the composition of hair, and there’s a wide variety of hair damage that can result when harmful chemicals and environmental factors cause a depletion of this protein (2).

The body has a natural system for the production of keratin. However, keratin hair treatment is a good option for supplementing natural keratin production for hair if need be.

The following are the key benefits of a keratin treatment:

1. Protective coating for hair strands

Keratin treatment provides a protective protein coating around each strand of hair. This helps to protect the hair shaft from constant exposure to environmental damage, and other stressors such as heat damage that can make the hair weak/porous.

2. A great solution to unmanageable hair

If you have unmanageable hair types, e.g., frizzy hair, curly hair, or even dull hair, keratin hair treatments are a good solution.

This chemical protein treatment can give you beautiful hair by improving hair smoothness and strength and also making your hair shiny.

3. Keratin hair treatment helps to save time

Keratin treatment can last up to six months. The advantage of this is that you can stay without styling your hair all through the period that the chemical treatment lasts.

The time spent at the salon for occasional hair styling can then be spent on other things.

4. Hair strengthening

Keratin treatment strengthens your hair by resealing the bonds between hair follicles. Those with damaged hair or conditions like extreme hair loss can avoid such with this chemical treatment.

Keratin hair treatment doesn’t just give you smoother hair, it also makes your hair strands resilient to breakage.

5. Keratin treatment helps you save costs for subsequent hair upkeep

You’ll only need a few upkeep appointments after doing a Brazilian keratin treatment (3). You can save a lot of money during the few months that your treatment lasts.

Other benefits include the prevention of constant exposure to heat styling and the promotion of hair growth in those experiencing poor hair growth due to hair breakage.

Here you go!

  • Avoid getting your hair wet within the first three days after the treatment. The keratin supplements applied during the salon treatment can be stripped off if you wash your hair during this time.
  • Don’t use sulfate-containing shampoos and conditioners. Hair products containing sodium laureth sulphate and sodium lauryl sulphate are harmful to keratin-treated hair (4).

When styling your hair, I recommend you use mild hair care products.

  • Make sure you do not wash your hair more than three times a week.
  • When sleeping in the first three days after a keratin treatment, make sure you protect your hair from crease formation.
  • Adopt the use of silk pillowcases in place of a cotton pillowcase. Silk pillowcases help to keep your hair smoother as they are frictionless.
  • Always blow-dry your hair after every workout session or any activity that can make you sweat.
