Keratin Amino Acids – These powerful protein fragments rebuild your hair from within, filling in gaps in the shaft to boost strength, elasticity, and shine. Heat sealing bonds them to the cuticle, creating a smooth, protective shield that keeps hair healthy, frizz-free, and effortlessly manageable.

Shea Butter – Packed with vitamins A and E plus essential fatty acids, shea butter delivers deep hydration and softness. It smooths the cuticle, tames frizz, and forms a heat-protective barrier during the treatment, leaving hair nourished, silky, and long-lastingly smooth.

Glyoxyloyl Carbocysteine – This advanced straightening/smoothing agent reshapes hair by softening and realignings and set the hair fibres. With heat activation, it locks in a straighter, frizz-free finish that’s sleek, manageable, and stays that way for months.

The rule is bleach BEFORE the treatment and tone AFTER the treatment.

We recommend waiting absolute minimum of 48 hours (minimum two washes) after bleaching to do an Express Smoothing Hair Botox This allows to hair to reset before the next treatment is applied.

Maintain Your Results Longer

With proper aftercare, your Terre a Mer Keratin Treatment can last 6 months or more. We stand behind our work with a 30-day Happy Hair Guarantee! (but you must use the aftercare)

Use the Right Shampoo ➡️ Skip Sodium Chloride

Always wash your hair with Terre a Mer’s sodium chloride-free shampoo. Sodium chloride although effective and safe, can weaken the treatment layer on the hair will bring frizz back sooner.

Limit Washing

Shampooing too often can strip away the treatment faster. Try to wash your hair sparingly, up to 2 times a week, to preserve smoothness and shine.

Be Cautious with Water Exposure

For the first week after your treatment, avoid swimming pools and open water (like the ocean). Chlorine, salt, and minerals can degrade the keratin seal and shorten the lifespan of your treatment.

Results typically last between 4 to 6 months, depending on your hair type, lifestyle, and aftercare routine. Some clients report results last longer when they carefully care for their hair. We provide a happy hair guarantee for 30 days.
