I have used this sample for the past week and haven’t noticed any changes to my hair. It does have a pleasant scent though.

It was an okay product, but not my favorite.
Sampled

It was an okay product but not my favorite. I enjoy great smells and it really was dull. I have thick, long hair that is very wavy.

sticky

left my hair feeling sticky and difficult to comb through. Difficult to apply evenly, felt like it clumped into sections .

Maybe it’s just me...

I’ve never been good with hair styling and I’m growing my hair out from a buzzcut on the sides so I need to start. I like the idea of this - protecting one’s hair from heat styling - but it made my hair feel starchy. Honestly I probably used it wrong but it wasn’t my favorite.

Dries my hair out
Sampled

I’ve never really been a fan of this brand to begin with and was not impressed with the spray. Of all the heat protectants this one dried my hair out and made it feel sticky and dirty. Will not use or buy again.

Light and delightful
Sampled

I always love my No.4 samples and this was no different. A light, nice smelling heat protectant that doesn’t weigh my hair down, or give it a funky texture like others do.

Do not like the smell
Sampled

I love this brand usually but this product does not smell good. I will use it till its gone but, I wouldn't purchase just because it doesn't smell nice.

Love this brand!
Sampled

I love this brand, I wish it was easier to find. It smells so good I’ve been asked many times what I use on my hair and then I’ll tell them to smell it(lol) the reaction is always about how great it smells!
