Best Keratin Masks for Damaged Hair

Keratin is a tough, fibrous protein naturally found in our hair, skin, and nails. It’s also a vital structural component that makes our hair strong. The hair is up to 85% keratin which forms both the interior structure (cortex) and the outermost layer of the hair (cuticle).

The amount of keratin in human hair diminishes with age and can be further negatively affected by heat styling, chemical treatments, aggressive brushing, and environmental stressors.

When the cuticle layer is damaged, moisture escapes easily and your hair can become overly dry. Without a healthy and compact cuticle layer, the inner layer of the hair is exposed to damage, which leads to weak and inelastic hair. The loss of keratin also makes your hair dull and prone to tangles and frizz.

While that may sound grim, your damaged hair isn’t subject to a short (pun intended) life of being covered by hats and scarves. 🙂

With the reconstructing power of keratin masks, all the unwelcome changes in your hair due to keratin loss can be minimized. In just several minutes, these intensive treatments will replenish missing or damaged keratin and dramatically improve the condition of your hair.

Will a Keratin Mask Permanently Fix Damaged Hair?

Hydrolyzed keratin proteins in hair masks will not permanently renew damaged hair. Protein particles that bind to the hair will rinse off over time, which is why keratin hair masks should be repeated once a week or bi-weekly to keep dry and over-processed hair strong, soft, and frizz-free.

How to Identify High- Quality Keratin Mask?

Make sure to read the label and look for ingredients such as amino acids, hydrolyzed keratin, hydrolyzed soy protein, hydrolyzed wheat protein, and hydrolyzed silk. To be sure that your mask will provide you with the precious benefits of hydrolyzed proteins, these proteins should be listed high up in the ingredient list rather than at the very bottom of it. HASK KERATIN PROTEIN Deep Conditioner listed below is a good example.

Some hair masks use “keratin” in their name, but don’t actually contain keratin proteins at all. These so-called keratin masks actually have a high content of silicones, which will either wash out with the next shampoo or build up on your hair and require a clarifying shampoo to eliminate them.

You should also avoid keratin hair masks that contain sodium chloride, which speeds up the process of stripping keratin from your hair.

Below is the list of several exceptional keratin reconstructive hair masks you might want to consider.
