The progressive keratin treatment remains one of the most requested smoothing services in Canadian salons for those looking for smoother, shinier, and frizz-free hair. In Canada, salons now offer a wide variety of options, including traditional formulas and formaldehyde-free keratin treatments designed to prioritize both hair and scalp health.
What Is a Progressive Keratin Treatment?
A progressive keratin hair treatment is not a permanent chemical straightening. Instead, it smooths and straightens the hair about 80–90%, while maintaining natural movement. Unlike older keratin formulas with harsh chemicals, this treatment does not damage the hair. On the contrary, it helps to recover and restore hair health, leaving it softer, shinier, and more manageable. Results usually last 6 to 7 months, and in some cases up to a year, depending on your hair type and the aftercare routine you follow.
Progressive Keratin vs. Brazilian Keratin: What's the Difference?
Both treatments smooth and straighten the hair, but they are not the same. A traditional Brazilian keratin treatment often relies on formaldehyde or formaldehyde-releasing agents to lock the hair straight, which can weaken sensitive or color-treated hair over time. A progressive keratin treatment works gradually: it smooths about 80–90% of the natural texture while rebuilding the hair fiber, with formaldehyde-free formulas that are gentle on the scalp. If your hair is fine, blonde, or bleached, a progressive formula like our Light Blue is the safer choice; for thick, coarse, or resistant hair, Chocolate delivers the deepest smoothing effect.
Progressive Keratin Treatment Cost in Canada
The price of a keratin treatment in Canada varies depending on the city and salon. On average, you can expect to pay between CAD 200 and CAD 500. Our Progressive Keratin Straightening treatments are among the most affordable on the market, and they are easy to apply if you follow the steps in our instructions.
Aftercare: How to Maintain Results
To maximize results, we recommend using sulfate-free shampoo and avoiding washing your hair too often. You should also follow your stylist’s advice to keep your hair soft and healthy-looking for as long as possible.
Can You Color Your Hair After Progressive Keratin Treatment?
Yes, you can colour your hair if you’ve had a keratin smoothing treatment. However, it is preferable to do the keratin treatment first and color your hair afterward. This way, you avoid any fading, since the keratin process and pre-treatment washes can slightly strip colour from the hair. Colouring after ensures more vibrant, long-lasting results.
Can I Apply a Keratin Treatment if My Hair Has Been Bleached?
Yes. We actually have a progressive keratin treatment called Light Blue, which is suitable for delicate, blonde, or bleached hair. It is just as effective as other treatments, but with a formula that helps prevent damage to sensitive hair and the scalp.
Is It Safe for Pregnant or Breastfeeding Women?
Yes. Our Progressive Keratin Treatment is 100% safe, formaldehyde-free, and fully Health Canada approved, which means it can even be applied during pregnancy or while breastfeeding. However, as with any cosmetic treatment, we always recommend that you consult with your doctor first to make sure it is the right choice for your individual situation.
