Soin Thermo-protecteur sans rinçage Thermal Guard

Love the formula of this Leave in, it gives more protection in my hair plus bonus the smell is heaven ❤️

En Vanny amamos este producto por su ligereza e hidratación! Incluso cuando su textura es suave, brinda la protección e hidratación necesaria para nuestra melena!

I’ve been waiting for Bounce Curl to come out with a heat protectant for so long, and it’s finally here! I already love their products, so I was really excited to add this one to my routine.
I blow-dry my hair regularly, so having a good heat protectant is important to me. The leave-in has a very lightweight texture, and the scent is a little different from their usual products—less fruity, which I actually really like.
This is definitely going to be a staple in my routine, especially on the days when I want to straighten my hair and give it some extra protection from heat.

This is the FIRST and ONLY product that has left my fine, curly hair defined, shiny (but not GREASY), and light (NOT flat/weighed down). I used it just as a leave in conditioner and my hair has never looked this good. Bounce Curl, don’t change a THING! Please! This is the product of my dreams!

My hair feels so healthy after using this. I use it on my daughter with straight hair (very small amount in ends) and my daughter with high porosity curly hair. Her hair has been dry no matter what I've used, but this has made it so much softer. A little goes a long way. The smell is pretty, but I'll say here too, that I wish their was a fragrance -free option.

Spray leave in is a game changer. I absolutely can’t get over the amount of control I know have over how much leave in goes into my hair. The added heat protection is everything! I am so impressed by this whole line! Obsessed!

I usually have to use some sort of curl cream before any fixative, as my hair tends to be on the dry side. However, my hair is also super fine, so most creamy products can be heavy and leave my waves weighed down. This product helped me detangle and brush through my hair easily, and also provided the moisture I need, without weighing it down. I used the ceramide jelly on top for more hold. Plus, with my hair being so fine, it's nice to know this is a heat protectant also, to keep my fine hair healthy on days I diffuse.

I love the Weightless Collection! I’ve been looking for products like this for what seems like forever. I’m so glad I finally found them.

Amazing formula and great bottle! Evenly distributes product. The scent is fantastic without being overpowering. My hair has never felt so soft. I've been using it with the hydra-lite styling cream. Love how much volume I can get with these products. Using on 2a-3c fine/fragile curls. Highly recommend if you are looking for a new leave-in conditioner. Love the packaging too! No excess plastic like false bottoms. Love everything about this new line!

Love this light weight leave in! Keeps my hair soft and smells great!

This my favorite heat protectant. I have curly/wavy hair, but honestly, I blow it out with a round brush and hair dryer most of the time. I still just adore Bounce Curl products for maintaining my hair health and this quickly became a must have for me. Leaves my hair so soft and manageable. I just love it!

This is an amazing lightweight leave-in conditioner spray that also offers heat protection! I use it before the Ceramide Jelly to make sure that my wet hair is fully detangled, moisturized, and primed to protect my curls during any subsequent heat styling when I'm going to diffuse my curls dry with a hair dryer! The formula is very concentrated, which means I only need to apply two to three spritzes of this leave-in spray onto my clean wet hair in order to achieve full coverage! Then I brush detangle to remove any knots and to ensure that the leave-in spray gets evenly distributed throughout all of my wet hair! It provides ample moisturizing slip without also weighing my curls down!

I wasn’t sure how to use this at first and now I can’t go a day without it especially in this FL heat. It’s hydration for my curls.

Smells amazing and I believe it’s making a big difference in protecting my hair. Great for refresh days too

This is the first leave in/heat protectant that I’ve consistently used because it’s lightweight.

It’s a winner because:
- doesn’t weigh down my fine 3a hair
- it’s a leave in AND a heat protectant
- works well with my other gels/mousses
- the smell is light and not overpowering imo
- the product is moisturizing and feels good gliding through my hair

My only critique is the spray bottle. I spray about 30 pumps directly into my hand and then evenly distribute the product in my hair. Sometimes the spray bottle can “choke” when I use the bottle at an angle. I have to hold it upright or place the bottle on a flat surface and pump in order to dispense the product. Other than that, the product itself is wonderful and I will definitely be repurchasing. [I wash my hair about 2x a week. I’ve had the same bottle since beginning of March 2026 and I’m about halfway done in July 2026.]

Light weight, smooths frizz and smells amazing

My curls love this!! Takes the frizz away and is a good refresher! Detangles well, I use it on my son as well and it’s perfect!

I love it 💕 I started diffusing my hair and this leave in heat protectant helps my hair not get damaged. It’s very lightweight for my 2c-3a curls

This is a great product! However, I am not crazy about the amount you get for the price. It is priced the same as the weightless lotion and that last A LOT longer than this spray. I think I would not buy it again and just use water. Especially since I am not one to put heat on my hair so the heat protectant aspect is not that important to me.

The leave in was really lightweight on my palms and easy to rake in my hair. It smelled good too!

This is a standout product! My hair is soft but not too soft, I'm on day 4 and I used this as my only refreshment. I was able to finger comb my hair without disturbing the curls and, my hair is so shiny! Please offer this in a salon size.

Smells amazing and leaves my hair soft.

No frizz in the NYC heat.

This one is my favorite of the entire line. The fragrance is different from the rest of the collection and I like this one better! I wish the entire weightless collection would smell like this.
I love that it's a leave in with heat protection.

When I first tried this line I fell in love with my hair all over again. I used this with the ceramide jelly and my hair was alive again. My wavy curly hair was so defined with no frizz. I love the smell of this product and it’s not strong where it’s gonna give me a headache. My journey finding a good clean hair care is over. You got a customer for life!!🫶🏽

WAVY HAIR GIRLS REJOICE! I have 2b/2c wavy hair and it works so great at defining my waves while still providing volume and managing frizz. I use it with the weightless shampoo and conditioner.

The packaging is great, love the smell, and would highly recommend for wavy, fine hair. Plus the nozzle on the bottle is fantastic because it evenly distributes a fine spray in a large area, which I love. As someone who has tried many leave in conditions from the drug store, and luxury companies alike, this has been my favorite by far. Would highly recommend!

I love the heat protection with this leave in. It’s also super light and the spray application is great. I usually have trouble with leave ins being too heavy and weighing down my curls, but this one has lived up to its name. Definitely a new staple in my routine.
