Yes! Our combination of treatment and technique straightens your hair and also repairs hair damage to make it healthier at the same time.
Our treatment uses a low pH amino acid formula to coat the hair tightly, sealing it closed to create a healthy straight look.

Keratin straightening operates differently from a chemical straightening service that straightens by  changing the internal structure of the hair and re-bonding it. The result for chemical or permanant hair straightening is that it damages your hair in the long term and event the short term.

The Terre a Mer Keratin treatment is not permanent and will last between 4-6 months.

The keratin treatment will only affect artificial colour due to its low pH natural formula. Any colour change can be corrected on the same day. Any lightening must be done strictly prior to the treatment as it can affect the keratin treatment.

The Terre a Mer keratin treatment contains no nasty for a typical child or adult, but no tests have been done on a pregnant woman, and we cannot provide a guarantee for its safety with unborn babies. We would recommend exercising caution asking your physician and choosing yourself as it is a personal one.

The only treatment that comes with a happy hair guarantee :) 

We always recommend doing bleaching BEFORE the keratin treatment and colour/toning AFTER the keratin treatment.

Bleaching or any lifting strips the pigment from deep in the hair to remove the pigment/colour. High level peroxide is almost always use and that will change the hair so we always recommend bleaching before the keratin treatment.

A colour and toner should be done post/after the keratin treatment as that will sit on top of the keratin and can counter act and tone or colour changes.

After Keratin Treatment

It is essential to use the right shampoo and conditioner following one of our keratin treatments as you want to maintain your investment. We only recommend the Terre aftercare, which has been specifically formulated to maintain the treatment and balance it. They are sodium chloride, sodium hydroxide free and contains hydration and protein to balance your hair. Take the best aftercare from our online store. Free Shipping.

Using the shampoo, conditioner, and other aftercare from Terre a Mer is essential. We also highly recommend getting a Terre a Mer Prescriptives Hydration Treatment once every four weeks.

The hydration treatments help treat your scalp by adding additional hydration to your hair and managing scalp health.

Any bleaching causing your hair to go lighter such as foils must be done before Terre a Mers keratin treatment. This rule is fundamental to follow as not to cause damage to the treatment.

You can colour your hair (depositing colour) on the same day but we do recommend 24 to 48 hours for best results as your hair will absorb the colour more effectively.

You can use what ever you want but its not guaranteed that it won't affect your treatment. Why? Every other shampoo, conditioner or treatment has their own formulations which can reduce the life or damage your treatment. Use at your own risk.

We recommend Terre a Mers aftercare range which has been designed to make your hair healthy and ensure your treatment lasts.

Avoid products containing sodium chloride (salt) and sodium hydroxide. Before swimming in the ocean or pool, use our great lipid protector called Intensive Rescue Therapy to coat your hair before you get into the water to give it some protection.

We recommend get the treatment every four months or three times a year. For individuals on a budget doing every 6 months is also a viable option. This ensures you get your healthiest hair and helps build on the previous treatment which maximises your investment.

Besides healthier and or straighter hair, some clients with a sensitive scalp may find some temporary oiliness flake for the first week after the treatment. This can be temporary and normal. Your pH on your scalp is rebalancing, but you can help it by using one hydration mask on your scalp and hair.

If this happens to you and you want help managing it use our Terre a Mer Prescriptive hydration treatment which uses essential oils to rebalance your scalp issue of dandruff or excess oil.

This can happen occasionally. Keratin is made from naturally extracting the amino acids from New Zealand sheep's wool, combined with high heat; the sulphur content can sometimes take a few washes to minimize and disappear. Do not worry, this is normal and will disappear.
