10What Is A Keratin Treatment

Keratin Treatment For Black Hair guide

Usually a four-step process, a keratin treatment is defined as a conditioning process that uses the aforementioned ingredients to saturate the hair and then high direct heat to seal the treatment onto the hair.

Unlike relaxers, keratin treatments are only able to modify the hair’s structure temporarily (3 months on average when kept properly), given that during processing hair is not submitted to irreversible heat damage from blow-drying or flat ironing.

The alkaline composition of the product allows the chemicals to loosen up the hair structure, while the heat expands and seals the hair with a strong silicone coating that grants the hair its soft and silky look. Previously relaxed or color-treated hair might react better to the treatment as the hair cuticle is open and allows the product to penetrate faster.

How long does keratin treatment last on curly hair? A properly applied keratin treatment can last up to 4 months on regular to high porosity hair.

12Best Keratin Treatment For Curly Hair

Keratin Treatment before and after

While it’s generally advisable you go to a licensed hair stylist who’s an expert in keratin treatments to get an assessment of your hair and a treatment that’s suited for your goals and needs, here are some general rules when selecting a DIY keratin treatment for curly hair:

  • Choose treatments with little to no formaldehyde
  • Consider purchasing the whole line of maintenance products for post-treatment care
  • Verify the authenticity of the product with the manufacturer before purchasing or applying: only buy from authorized resellers or call and verify the lot number. Bootleg keratin treatments are not uncommon and due to the nature of the ingredients, it’s very important to keep an eye out.
  • Use high-quality tools: Precision flat irons are a must for a successful keratin treatment. Your flat iron must be able to heat evenly for long periods of time to minimize the risk of under or over processing your hair and causing heat damage.

13Hair Care After A Keratin Treatment

The way you take care of your keratin treated hair is just as important as the treatment itself. Good maintenance is based on avoiding the use of hair products that might reverse the hair to its natural curly state or strip it off from the conditioning ingredients.

To take care of hair that has undergone a keratin treatment consider:

  • Doing a hair trim every 6 weeks.
  • Use sulfate-free shampoos and conditioners.
  • Use keratin enriched deep conditioners once a week.
  • Invest in a good heat protectant before heat styling.
  • Aim for the minimal amount of heat possible when heat styling: You can air dry your hair in a ponytail before flat ironing or curling.
  • Avoid getting your hair soaked in chlorine or beach water too often.
  • Wait at least two weeks to apply any new hair color.
  • Don’t do more than three consecutive treatments to avoid permanently altering your curl pattern.
  • Wrap your hair at night or use a satin pillowcase to minimize friction and breakage.
