GENESIS defense thermique by Kérastase ,

Strengthening, anti-fall and anti-breakage styling fluid for weakened hair.

Discover the new GENESIS care range, a complete treatment with double anti-loss action for weakened hair prone to loss.

It protects the roots weakened by internal factors such as stress, hormonal imbalances or diets on the scalp, while preventing fiber breakage in the mid-lengths and ends due to external factors such as brushing, heat tools or pollution.

Benefits:

This fluid thermal protector protects the fiber to prevent breakage and facilitates styling by providing hydration and softness, promoting hair elasticity and reducing breakage during brushing and drying without adding weight.

It is enriched with native Edelweis cells, known for their antioxidant power, and Ginger root known for its protective effect against external aggressors.

In addition, it has a spray milk texture and a delicious, fresh and invigorating bergamot fragrance, with citrus and floral notes that promote a vital and positive mood.

One of my favorite brands
I bought the line on the recommendation of my hairdresser, and I am delighted with it, at least for now. I combine it with Olaplex shampoo and conditioner with alternating washes and both lines work great for me.

FAQ Kérastase - GENESIS defense thermal

?
Does this product give volume to hair? Thank you.
Translated by Google
Consuelo09/03/2024
Hello Consuelo. Thanks for your question. No, it does not give volume to the hair. Its main function is to protect hair from heat up to 220°C, strengthen it and prevent breakage. We're here to serve you.
?
Can it be used on a 14 year old teenager?
Translated by Google
Nuria14/11/2023
Hello Nuria. Thank you for your inquiry. Yes, it can be used by teenagers. We're here to serve you.
?
Can it be used on dry hair to seal the ends? I use the kerastase biphasic and I don't know if this one will suit me better. Thank you
Translated by Google
Nerea12/12/2020
Hello Nerea! This in particular, in addition to being a thermal protector, helps to strengthen the hair, prevents breakage and provides softness and hydration. You can use one or the other depending on the needs of your hair. All the best.
?
For fine, colored hair and oily scalp, would it act as a serum on the hair ????
Translated by Google
Sonia29/11/2020
Hello Sonia! It can go very well and will help you to strengthen and prevent hair breakage thanks to the thermal protection (remember that you should not apply it to the scalp), however, it is not a serum and the texture is liquid and is applied by spray . All the best.
?
Can I use it daily or only when I am going to do my hair with a hairdryer or iron? Thanks for your time.
Translated by Google
Lali16/08/2020
Hi Lali! This thermal protective fluid is recommended for all types of weakened hair that seek to avoid hair breakage resulting from drying. If you are looking for a treatment for daily use, we recommend that you consult the rest of the products in the line. All the best!
?
Can it be used for both the heat of the iron and the heat of the dryer?
Translated by Google
Maria10/08/2020
Hi Maria, thank you for your question. Yes, it protects from the thermal heat of the iron or dryer. All the best

Hello, does the product require rinsing? Or does it end up absorbing it by itself into the hair?
Translated by Google
Inmaculada04/08/2020
Hello Immaculate, thank you for your inquiry. This spray does not require rinsing, it is applied to damp hair and acts by covering the hair fiber and protecting the hair from external aggressions, as well as providing hydration. All the best.
?
I have little and very fine hair, can I use it? Can I apply it to the root?
Translated by Google
Victoria28/07/2020
Hello Victoria, thank you for your inquiry. This product can be perfect for styling your hair type, thanks to the native Edelweis cells, known for their antioxidant power, they will work to strengthen your hair and help it look healthier, preventing hair loss and breakage. On the other hand, you should apply it throughout your hair evenly on wet or dry hair. However, if you are looking for a product that also treats the root, we recommend GENESIS cure anti-chute fortifiant ampoules, it will protect your scalp with roots weakened by factors such as stress or hormonal imbalances, while also preventing the break in the middle and ends. All the best.
