    How to Choose the Best Protein Treatment for Curly Hair?

    Below are the steps to consider before picking the best protein treatment for curly hair—

    a) Hair porosity- Before you invest in a protein treatment for your curly hair, find out the hair porosity! If you have a highly porous hair type, pick a heavyweight formula that helps the strands soak up all the nutrients. On the other hand, if you have low-porosity hair, a lightweight formula is needed so that it gets fully absorbed by your strands. 

    b) Ingredients- Look for ingredients like vegetable protein, amino acids, keratin, collagen, soy protein, etc on the product’s packaging to ensure that it contains potent protein. Similarly, avoid ingredients like paraben, sulfate, phthalates, and SLS to ensure your strands remain free of nasty chemicals.

    c) Formula- Look for a vegan-friendly and cruelty-free formula if you don't want to cause any harm to living beings in the name of haircare! You can go for vegetable protein in order to meet the needs regarding your protein treatment.

    Now, take a look at the benefits of the protein treatments before proceeding—
