Getting a protein hair treatment can transform your hair—leaving it soft, shiny, and frizz-free. But to maintain those results and enjoy the full benefits of a hair treatment, it’s essential to follow the right aftercare routine. In this blog, we share expert tips to keep your hair smooth and healthy for weeks after your keratin treatment.
1. Don’t Wash Your Hair Immediately
After a hair smoothing session, avoid washing your hair for at least 72 hours. This allows the protein treatment for hair to fully bond with the hair strands and lock in the results.
2. Use Sulfate-Free Shampoo and Conditioner
To protect your protein hair treatment, always use sulfate-free, salt-free shampoos and conditioners. These formulas are gentle on the hair and help extend the life of your hair care protein treatment.
3. Avoid Tight Hairstyles or Clips
For the first few days after a Brazilian hair treatment, keep your hair down. Avoid tying it back or tucking it behind your ears, as this can leave unwanted creases or waves.
4. Skip Hair Dye and Harsh Chemicals
Do not color or chemically treat your hair for at least two weeks after the keratin treatment, as your hair is still in a sensitive state and needs time to recover and stabilize.
5. Limit Heat Styling
Although your hair will already be smooth and sleek after a protein hair treatment, frequent use of heat tools can weaken it over time. Only use flat irons or blow dryers when necessary, and always apply a heat protectant.
6. Deep Condition Regularly
Moisture is key. Use a deep conditioning mask once a week and light oils like argan or coconut oil to keep your hair hydrated and to enhance the effects of the hair treatment.
7. Trim Your Ends Regularly
Split ends can develop over time even with great care. A small trim every 6 to 8 weeks helps maintain the health and appearance of your smooth, treated hair.
Final Thoughts
A protein treatment for hair offers outstanding smoothing and strengthening results, but proper aftercare is crucial for maintaining those benefits. By following these simple yet effective tips, you can make your Brazilian hair treatment last longer and keep your hair healthy, soft, and manageable.
