Causes of Keratin Damaged Hair

Before we dive into the solutions, let's first understand the common causes of keratin damaged hair:

  • Excessive use of heat styling tools, such as hair straighteners and curling irons
  • Overwashing or using harsh shampoos
  • Chemical treatments, such as hair coloring or perming
  • Exposure to sunlight, wind, and pollution

How to Repair Keratin Damaged Hair

1. Use a protein-rich hair mask

One of the best ways to repair keratin damaged hair is by using a protein-rich hair mask. Look for products that contain ingredients such as keratin, collagen, and amino acids. Apply the mask to damp hair and leave it on for 15-20 minutes before rinsing it off with cool water.

2. Cut back on heat styling

Heat styling tools can cause significant damage to your hair. If possible, try to limit your use of these tools or switch to a lower heat setting. Additionally, always use a heat protectant spray before styling your hair.

3. Switch to a milder shampoo

Harsh shampoos can strip your hair of its natural oils, leaving it dry and brittle. Look for shampoos that are sulfate-free and contain natural ingredients such as aloe vera and coconut oil.

4. Protect your hair from the sun

Exposure to UV rays can cause your hair to become dry and prone to breakage. To protect your hair, wear a hat or use a leave-in conditioner that contains SPF.

5. Eat a balanced diet

A healthy diet is essential for healthy hair. Make sure you are getting enough protein, vitamins, and minerals in your diet. Foods such as leafy greens, nuts, and fish are particularly beneficial for hair health.
