Great stuff!

I’m using this along with the 4 in 1 spray. My naturally curly, frizzy hair is so smooth now. I will keep buying. I just bought the shampoo and conditioner from this brand too. I can’t wait to try them!

I love it!

It's a great product and does what it's designed to do...smooth out frizz and curl. For some reason, my bangs decided to kink up for the first time ever. I wasn't able to straighten the hair out with just blow drying, but this product does the trick. Thank you!

Love it!

I have a lot of hair and it likes to do it’s own thing! At last I think I’ve found the answer.

You should rename it, Magic in a Can!!!

Glad I got it

I never spend a lot on hair products. I’m so glad I made an exception this time. I love how my hair looks and feels, and I’ve gotten so many compliments! And it smells really good too!

Love this stuff

Makes my dry fuzzy hair very smooth, shiny, silky and straight. It’s winter now with no humidity so it works well. The real test will be this summer when my hair tranforms into the Lion King in the humidity.
