When you decide to make a change to your hair, whether it’s a new color or a different texture, you want it to last. The term “permanent” can be a bit misleading, as it suggests a change that will never fade. In the world of hair, “permanent” simply means the treatment will last until your hair grows out, but that doesn’t mean it’s immune to fading or wear and tear.
So, how long can you truly expect your new look to hold up? The answer isn’t a single number, as it depends heavily on the type of treatment you choose and how you care for it afterward.
The Lifespan of Permanent Hair Color
Permanent hair dye works by opening the hair cuticle and depositing color inside the hair shaft. This color will not wash out. However, your hair will continue to grow at an average rate of half an inch per month. This means you will see your natural roots reappearing in about four to six weeks. While the color itself is permanent, it can fade over time due to washing, sun exposure, and heat styling, often lasting between 6 to 8 weeks before a refresh is needed for vibrancy.
What About Permanent Hair Straightening?
Permanent straightening treatments, like relaxers or keratin treatments, alter the hair’s internal bonds to smooth out curls and waves. These results are also outgrown as your new hair grows in with its natural texture. You can typically expect the sleek, straight effect to last anywhere from three to six months, depending on your hair’s growth rate and how quickly the treatment wears off from washing.
Making Your Permanent Hair Treatment Last Longer
Your aftercare routine plays a huge role in preserving your investment. To extend the life of any permanent service, switch to a sulfate-free shampoo and conditioner system designed for color-treated or chemically processed hair. Washing your hair with cool water can also help keep the hair cuticle sealed, locking in color and smoothness. It’s also wise to minimize the use of hot tools and always apply a heat protectant spray when you do style.
Ultimately, a permanent hair treatment is a long-term commitment that grows out with you. By understanding the process and caring for your hair properly, you can enjoy your beautiful, fresh look for as long as possible before your next salon visit.
