The Dos And Don’ts Post Keratin Treatment

April 30, 2024

Everyone with wavy or curly hair has at least once thought of lustrous straight hair that is frizz-free and manageable. If you are also one of those dreamers, keratin treatment can help you out! This hair treatment leaves hair smoother, with shinier locks. However, since it has chemicals like formaldehyde, the aftercare is a bit tricky. Let’s discuss details about the dos and don’ts of keratin treatment.

What Is Keratin Treatment?

Keratin treatments are a chemical process that helps hair regain smoothness, shine and eliminates the frizz, making it look straighter. The treatment starts with a keratin-based product applied to your hair and then sealing it with a flat iron.

This step alters the cross-linking of the keratin strands and turns curly or wavy hair straight. The good news is that keratin treatment is a one-time wonder, and the effects easily last for several months. However, it requires meticulous maintenance, such as avoiding washing the hair for at least 2 days after the treatment. That, too, can only be done with a sulfate-free shampoo and conditioner and salt plus chlorine-free water.

How Long Does It Last?

This popular hair-smoothing and straightening procedure coats a layer of protein (keratin) to the hair. It is then sealed to the hair’s cuticle, preventing the movement of moisture in and out of the strands, making your hair smoother and frizz-free hair that lasts for about 3 months.

Typically, this process takes between 1-3 hours to complete. The stylist initiates treatment by applying the keratin treatment to your hair, rough-drying it, and then finishing off with a straightening machine to seal and activate the coating.

The Dos and Don’ts

Keratin treatments show the best results on coarse or unruly strands; however, they do have some risks. This is why strong adherences to the dos and don’ts post keratin treatment is required.


  1. Wash Hair Less Often: Keratin treatments are bound to last longer if you wash your hair with greater gaps. Try to wait at least 2 days (48 hours) after the treatment before washing your hair, and then put them under water only once or twice per week.
  2. Use a sulfate-free shampoo and conditioner: Sulfates are known to strip away the keratin from your hair. Therefore, it is crucial to use a sulfate-free shampoo and conditioner after your treatment. The good news is that you do not have to waste your time in markets deciphering the product’s capabilities. Now, the companies have come up with specific options that you can ask for.
  3. Use a wide-toothed comb: Since the cross-linking of your hair takes place, it may become more prone to tangling. This is why we suggest using a wide-toothed comb that gently detangles your hair because of the space it has, avoiding pulls or breaks.
  4. Protect your hair from heat: Since keratin lock requires usage of a flat-iron, it may make your hair more susceptible to damage from heat styling tools. But fear not, you can use a heat protectant spray before passing your hair through a curling iron; however, try to avoid using high heat settings.
  5. Trim your hair regularly: Regular trims can prevent split ends and keep your hair healthy.


  1. Don’t Wash Your Hair Immediately Post-treatment: Let the keratin treatment set in your hair and wait at least 48 hours before washing. Going underwater too soon can reduce its effectiveness.
  2. Stay Away From Hairstyles That Can Dent Your Hair: Steer clear of putting your hair up in ponytails and braids because they can dent your keratin-treated hair.
  3. Avoid Rubbing Your Hair with your hands: Refrain from rubbing your hair with your hands, as the malleable nature of keratin-treated hair can make it susceptible to damage.
  4. Don’t Perform Heavy Workouts: Since working out can make you sweat, the entry of moisture can ruin the results of your hair.
