Protein treatment for hair

What is it and why you should do it

If you don’t know yet, our body produces a lot of different proteins – you may have heard of keratin before, the substance that composes most of the hair. Unfortunately, due to external factors such as heat, pollution, wind, and chemical treatments, keratin can be damaged. That’s why protein treatments are so important: they restore the damaged hair’s protein, adding strength, smoothness, and brightness to it[1]Perkins, S. (2018, June 11).

You may be asking yourself “How do I know if I should do a protein treatment?”… Don’t worry, because there are some very noticeable signs your mane needs an extra protein boost:

  • Your hair is dyed – Due to the number of chemicals involved in the dyeing process, color-treated hair becomes damaged. If you want to keep your hair healthy, you should do a protein treatment.
  • You’re losing your hair – It is normal to lose around a hundred strands of hair a day. However, if you find yourself with an absurd amount of hair on your hand after you comb it, you should probably add some protein to it. 
  • Your hair is dry and has a lot of frizz – Most of the time, frizzy dry hair means porous hair. If you tried hydrating it with a hair mask and it didn’t solve the problem, a protein treatment could be the answer. 
  • Lifeless hair – If your hair is simply lifeless (non-elastic, dry, brittle, and weak) and you’ve tried other hydration methods before, don’t lose any more time and get yourself a protein treatment done ASAP!

So now you know the signs that your hair needs some extra protein. But what does a protein treatment consists of[2]Globyte, E.

The frequency of a protein treatment depends on both the type of treatment you choose (intense or simple) and your hair type. There are both intense protein treatments that usually demand a hair salon visit as well as simpler treatments that can be done at home. Normally, “easy” protein treatments can be done once a week, while complex ones should be done every 4-6 weeks. 

Protein treatments for hair can be found in the form of oils, lotions, conditioners, and hair masks. Below, we are going to show you 2 different protein treatments from the Brazilian brand Nazca, that will leave your hair smooth, strong, and gorgeous! 


As we said before if your hair brittle, fragile, and frizzy, you are in need of some serious protein repair! Nazca’s Keratin Repair mask will hydrate and add protection to your main. And since it’s a hair mask, it is very simple to use: after shampooing and conditioning, apply the mask throughout the hair length, leaving it to act for 3-5 minutes. After that, rinse it well and your hair will thank you! You can redo this treatment once a week, ok?


If your hair is EXTREMELY lacking protein, Nazca’s professional Brazilian Keratin Lotion could be your savior. It will leave your hair really smooth (and straight for a while). But be aware: you may need to go to a professional because this product is strong and a little complex to apply: 

  1. Wash your hair with an anti-residue shampoo and  let it completely dry;
  2. Divide the hair into four parts and apply the  Brazilian Keratin with the help of a brush to the entire length of the hair;
  3. Let it act for about 15 minutes (don’t leave it for more than this!); 
  4. With a hairdryer, dry the hair and use a brush to straighten the hair (you  may use a flat iron, as well);
  5. After your hair cools down, wash it with warm water and apply a hair mask or a conditioner for about 3-5 minutes;
  6. Rinse it, and done!
