Good dupe for other expensive sprays
I’ve been using the Marc Anthony Anti-Frizz Heat Protectant Spray for a few weeks, and I’m really impressed. It has a lightweight, non-sticky feel and doesn’t leave my hair greasy or weighed down. I spray it on before blow-drying or straightening, and it really helps smooth frizz and keep flyaways down.My hair looks healthier and shinier, and I love that it protects against heat while still feeling soft and manageable. The scent is pleasant without being overpowering. Even on humid days, I notice less frizz than usual.Overall, this is a fantastic heat protectant that delivers great results for an affordable price. I’ll definitely keep it in my hair routine!

Bougie on a budget
This Marc Anthony Ultimate Blowout Spray understood the assignment. It gives smooth, shiny, frizz free results without making my hair stiff, sticky, or weighed down. My blowouts last longer, look more polished, and somehow still move like I didn’t try that hard. It also cuts down drying time, which feels like a personal favor on busy days. My hair looks fuller, softer, and way more expensive than it has any right to. If you want that fresh salon blowout vibe at home without selling your soul or your time, this is it.

Love this product I always recommend it to people
I will forever recommend this product!First off my hair is so soft after I use it and not weighed down at all, it truly feels like it prevents damnage from heat and it smells SO GOOD! You get a fair amount for the price, its a good sized bottle and its just high quality. The bottle sprays nicely and is easy to spray even with my hands having trouble holding onto stuff from nerve damnage & carpal tunnel. The bottle is easy to hold onto as well.

Humidity-Proof Hair in One Spray
This product has been solid in high humidity. I spray it on damp hair before blow drying, and it noticeably cuts down on frizz and puffiness, without making my hair feel coated or greasy. My hair dries faster, looks smoother, and holds a sleek finish longer, even on damp days. The scent is light and fades quickly, and I like that I’m getting heat protection and frizz control in one step.

Great product for hard to straighten hair
I have thick curls – about 3C with some parts of 3B. I do like my wearing my hair straight just for different looks, and this it made the process of drying my hair a bit easier and my hair feels really silky smooth. Even though it’s kinda like a thicker spray, I couldn’t feel it in my hair which I love. I still needed to use my flat iron at the end to make it perfectly straight but I really have some tough curls. Also it protects against heat which is a must for curls! Overall I will keep using this when I straighten my curls bc I loved the way it felt and looked. Smelled good too.

Nice
This stuff smells beautiful. It has a nice, clean scent that isn’t too strong. It’s a watery heat protectant as opposed to the oily kind. The atomizer does an amazing job at dispersing the product evenly.

Smooth, Frizz-Free Results!
This blowout spray leaves my hair smoother, shinier, and less frizzy, especially on humid days. It’s lightweight, smells nice, and adds good heat protection without feeling greasy. It doesn’t make your hair grow, but it does help you get a cleaner, faster blow-dry.A great option if you want softness and frizz control.

Lo compre por qué leí buenos comentarios, protege y no se siente pesado en el cabello, al contrario lo deja muy manejable.

I have curly hair that I like to straighten on a regular basis. I have tried a lot of different products. This one does a great job protecting my hair and also keeps it silky and straight for days. I have now bought other products from Marc Anthony and will definitely continue buying this product as well.Highly recommend it.

I have been religiously using the Grow Long blowout since it came out last year and have LOVED it. However, when i saw this product launched I immediate purchased it for my daughter who has coarser and curlier hair than me (i just have frizzy wavy hair). While her hair needs moisture and softness due to its coarser texture, most moisturizing smoothing products still weigh her hair down. The Curl-to-Straight made her hair SO smooth yet also lightweight and bouncy. AND the results lasted her over a week! She says it is her new go-to for when she wants to blowout her hair.
