Why Do You Need a Hair Mask for Keratin Treated Hair?

how masks improve hair health after keratin intensive treatments

A hair mask helps to fortify your hair after chemical treatments like keratin, color, or bleaching, which can cause hygral fatigue during the process.

Hygral fatigue happens when the hair shafts have to swell (opening the cuticles) to absorb the treatment and then unswell to seal in the treatment (with heat).

The fatigue and stress can leave your hair stressed out, in a traumatic state that may eventually lead to breakage because of tiny fractures that may occur when it’s chemically manipulated.

So here are the ways a hair mask can help your hair after a keratin treatment:

  • Fortify the hair strands:To restore order, a hair mask brings in reinforcements in the form of keratin, amino acids, and healing antioxidants like argan oil to help your hair recover quickly. Moreover, once your hair starts to rebuild its strength back, continuous use of a hair mask with keratin renews your treatment progressively to make it feel fresh so it can last longer.
  • Stop breakage:By fortifying the hair fibers from within, a hair mask also makes your hair more resilient against minor breakage, which is not always noticeable by the naked eye but can inevitably lead to hair thinning from the top.
  • Renew keratin:Imagine a keratin hair mask as a booster for your treatment. Every time you use it, it tops up the keratin coating gradually lost when washing the hair. I always use a keratin mask to prolong the length of my treatments. It always helps me go beyond the 3 months until my next salon top up.
  • Intensify Hair Color:A hair mask can help intensify and revive color-treated hair that looks dull. When your hair is well hydrated from within, it makes your hair color glow. When it looks dry and frazzled, it makes your color look dull. So add more glaze and let your hair color shine in all its glory.

How to Use a Hair Mask after Keratin Treatment

  1. Wash your hair first:
    Clean hair absorbs better and faster.
  2. Apply the amount recommended in the instructions:
    You don’t want to burden your hair by using too much for too long. This can lead to protein overload, which makes the hair brittle and dry.
  3. Rinse off thoroughly:
    Rinse off the mask thoroughly until the water runs clear.

How Often to Apply a Hair Mask on Keratin Treated Hair

If your hair feels in good condition, use a hair mask once a week or once every 2 weeks.

If your hair tends to feel too dry, then use it twice weekly.

says Lisa Caddy, Trichologist and brand ambassador for Philip Kingsley.

Ideally, you would use a hair mask to heal your hair back into a healthy state and then gradually reduce the usage to around once or twice a month.

However, it’s important to note that using too much of it won’t work any magic shortcuts. It can make your hair feel worse.

What to Look for When Buying a Hair Mask for Keratin Treated Hair

Sulfate-free and Sodium Chloride Free

Sulfates and salts are the enemies of keratin and colored hair. They are abrasive chemicals that strip anything that coats the outer layers of the hair – even your hair’s natural oils.

You’d use sulfates and salts to remove a keratin treatment.

So avoid hair masks that contain sulfates and salts.


Although hair masks are known to be heavy and creamy, most of them should rinse out easily without creating any residues in your hair. So keep an eye out for reviews like “sticky and hard to wash out”.

These are the red flags that the hair mask has hard silicone and quads that stick to the hair and require several washes to rinse out.

You should always refrain from over washing your hair after a keratin treatment.

You want a hair mask that’s easy to apply and easy to wash out.

Enriched with Micro Keratin

Using hair products that contain hydrolyzed keratin helps your keratin treatment last longer. It also helps to improve the texture and strength.

So look for a mask rich in keratin, protein, and amino acids.

Your Hair Type and Condition

Hair masks are created for specific hair types to target specific conditions.

So if you have curly hair, stick to a mask designed for curls. If you have fine hair, stick to one that caters to fine and thinning hair.

The right hair mask for the right hair type and condition ensures that you won’t overuse or underuse the product because each mask has its specific application instruction and frequency of use.

A hair mask is an essential product you need in your hair care routine after a keratin or Brazilian hair treatment.

Besides boosting moisture and hydration, a keratin hair mask also provides essential nutrients deep into the hair cortex to heal damage and make your hair fibers more resilient.

And finally, it helps to renew your treatment to give it more mileage.
